This is an "environmentally friendly" septic tank, so there is no need to pump water and fertilizer?

"The builder said that this is an environmentally friendly septic tan, so there is no need to pump water and fertilizer! I have lived in the house for more than 3 years and have not pumped water and fertilizer. The toilet is in normal use, and now I want to clean and maintain it."

"Our house is a 20-year-old house and recently changed to an environmentally friendly septic tank. At that time, the manufacturer said that this kind of septic tank can be used without pumping water and fertilizer. Only the old-style septic tank needs to be pumped, but the drainage has smelled recently. Why is this happening? ?"

"The builder told us that we are using an environmentally friendly septic tank, so we don't need to pump water and fertilizer, but the toilet on the first floor is a little difficult to flush, so we still need to pump water and fertilizer, right? The house is 12 years old."

Recently, the editor of Green Earth received several calls from homeowners to say this. My conclusion is: No soup~ No matter "traditional" or "environmentally friendly" septic tanks, as long as there is a squatting toilet every day, you must pump water and fertilizer regularly! Especially "environmentally friendly" septic tanks, if the water and fertilizer are not pumped regularly, the price to be paid in the future is higher than that of traditional septic tanks.

The new house uses an "environmentally friendly" septic tank. Is it okay to live in it for three years without pumping water and fertilizer?

The key is not environmental protection or traditional septic tanks, but "new houses"!

"Environmental" and "traditional" septic tanks, the first tank design of both is a "sedimentation tank", also known as a primary sedimentation tank or a septic tank. It is the place where the septic tank intercepts and temporarily stores feces. This pool settles down to form water and fertilizer.

The first, second and third tanks of traditional septic tanks are all "sedimentation tanks". However, only the first tank is a sedimentation tank, the second tank is a "biological aeration tank", and the third tank is a "disinfection tank", as shown in the figure below.

Because the septic tank in the new house is also new, the septic tank is originally empty. Generally, an "empty" sedimentation tank can last for 2 to 3 years without pumping water and fertilizer. The main difference is: pumping water and fertilizer once a year can Chang ensures that the sedimentation tank has enough space to accommodate feces to ensure that the toilet and septic tank can be used normally; water and fertilizer are pumped every three years. During this period, the sedimentation tank space is getting smaller and smaller due to the continuous deposition of water and fertilizer. When it is filled with water and fertilizer, the toilet on the first floor will not flush properly, and in severe cases, feces will come out of the manhole of the septic tank (as shown in the picture below), and the gold in the house will flow all over the floor!

In order to prevent the "sedimentation tank" of the septic tank from being filled with water and fertilizer, it is recommended that everyone should pump water and fertilizer once or twice a year to maintain the quality of the home environment.

If you use an "environmentally friendly" septic tank, if you do not pump water and fertilizer regularly, you will pay a higher price in the future than traditional septic tanks!

If you have lived in the new house for 2-3 years and have not pumped water and fertilizer, and have not encountered problems such as poor flushing of the toilet, squeaking, manure, etc., please don't be too happy, it means that your septic tank is not in a beautiful mood. Prepare to give the master a shocking education!

If the septic tank has not pumped water and fertilizer for more than three years, the water and fertilizer produced in the past few years will not disappear, and the water and fertilizer will be deposited in the first tank. When the pool is full, it is piled into the third pool.

When the three pools of the septic tank are full of water and fertilizer, the toilet will start to have problems such as poor flushing, squeaking, and even feces from the manhole of the septic tank (as shown in the figure below)!

Although the three septic tanks are full, the symptoms are the same as when the first tank is full. The toilet flushing is not smooth, the water is squeaking, and the manhole of the septic tank is full of feces. However, the solutions and costs of the two are different. A world of difference!

When the three tanks of the septic tank are fully filled with water and fertilizer, it cannot be solved simply by "pumping water and fertilizer", because the following three problems will be encountered:

(1) The water and fertilizer are hardened, and the water and fertilizer truck cannot be pumped.

When the water and fertilizer are piled in the septic tank for a long time, the water content will gradually decrease, and finally the water and fertilizer will be dehydrated and hardened. Especially when the septic tank has not pumped water and fertilizer for ten years, the water and fertilizer will be as hard as a stone, and even people standing on it will not sink. The petrochemical water and fertilizer cannot be removed by the water and fertilizer truck. It needs to be slowly excavated manually with a round shovel or an electric drill, as shown in the figure below, which is very time-consuming and labor-intensive!

(2) The ditchholes in the septic tank are too small, or the manholes in the second and third pools of the septic tank cannot be found?

The manholes in the septic tank are all large manholes with a diameter of 50 cm, but at the beginning of building a house, the builders (or homeowners) will think that the manholes of the septic tank are too large, too ugly, and smelly, etc. The reason is to shrink and hide the original manhole, but these modifications will cause troubles in cleaning the septic tank in the future. The details are as follows:

(1) Reduce the large manhole with a "diameter of 50 cm" when the septic tank leaves the factory to a small manhole with a diameter of 10 cm.

Trouble: The petrochemical water and fertilizer need to be excavated manually, but the small manhole with a "diameter of 10 cm" cannot be used for this operation, and the adult manhole of the septic tank must be restored.

(2) The second and third manholes of the septic tank are covered by tiles or decorations, and only the first manhole is reserved for pumping water and fertilizer.

Trouble: When the first, second, and third pools of the septic tank are full, it is not possible to remove only the first pool of the septic tank, but the water and fertilizer of the second and third pools of the septic tank must be treated at the same time. Therefore, it is necessary to restore the manholes of the original three pools of the septic tank, and then remove the accumulated water and fertilizer in the first, second and third pools.

(3) The internal parts and structures of the second and third environmental protection septic tanks are damaged.

The first, second and third tanks of traditional septic tanks are all sedimentation tanks, and the sedimentation tank is an "empty" tank. Its function is to stack water and fertilizer. Therefore, if the water and fertilizer are piled into the second and third tanks, you just need to find a way to remove it. That is, it is less harmful to traditional septic tanks.

However, only the first tank is a sedimentation tank, the second tank is a "biological aeration tank", and the third tank is a "disinfection tank". In the biological aeration tank, there are air supply pipelines, air diffusers, filter materials and other parts; in the disinfection tank, there is a chlorine ammonium cylinder structure, as shown in the figure below. Therefore, when the water and fertilizer are piled into the second and third pools of the environmental protection septic tank, it will directly damage its internal parts and structures.

In addition, when water and fertilizer accumulate in the second and third pools for a long time, it will gradually evolve into petrochemical water and fertilizer. However, the piping, filter material, air diffuser, and chlorine ingot cylinder in the environmental protection septic tank are all delicate parts, which cannot stand the toss and beats. Therefore, after the water and fertilizer are manually excavated, most of these two tanks are also scrapped and cannot be normal. used.

For the above reasons, when using an "environmentally friendly" septic tank, please regularly pump water and fertilizer 1-2 times a year, and use [Green Earth Septic Cleaner] water and fertilizer decomposing enzymes to maintain the septic tank. Enzymes can decompose the dead water and fertilizer that cannot be pumped by the water and fertilizer truck, especially the water and fertilizer accumulated near the end of the manure pipe and the inlet of the septic tank (as shown in the figure below), slow down the accumulation of water and fertilizer, and prevent the water and fertilizer from being piled into the second and third pools too quickly. The septic tank is functioning normally.
