Water and fertilizer trucks discharge oil to pollute farmland, and enzymes "turn pollution into fertilizer"
Recently, when I searched the Internet for sewage treatment information, I found that there were quite a few news about water and fertilizer trucks stealing and polluting farmland this year. Among them, this news made me the most incredible--“Water and fertilizer trucks were arbitrarily discharging water and fertilizer on the roadside and were caught live on the spot by the Environmental Protection Bureau”, Because this photo is so clear, even people and cars are in the mirror, because the driver of the water and fertilizer truck did not steal the discharge after dark, but stabbed the pollutants directly in broad daylight. Discharge into farmland as if it were "legal"?
In fact, the incident of water and fertilizer truck stealing has been repeated over the years. Except for a small part to save costs, the biggest reason is that there are too few water and fertilizer treatment plants set up by the government. According to ITRI estimates, Taiwan's daily water and fertilizer removal volume exceeds 5,000 tons, but in Taiwan, only five cities, including Taipei, Hsinchu, Taichung, Tainan, and Kaohsiung, have water and fertilizer treatment plants. The other 18 counties and cities are basically There is no water and fertilizer treatment facility; and the five water and fertilizer treatment plants in Taiwan only process 890 metric tons of water and fertilizer per day. In other words, at least about 4,000 metric tons of water and fertilizer are lost every day in Taiwan. It is reasonable to speculate that most of these 4,000 tons of water and fertilizer are secretly discharged into the country. river or soil. (For more information, please refer to 4,000 tons of water and fertilizer flowing through Taiwan every day)
Before, my uncle’s bamboo shoot garden had also been polluted by water and fertilizer trucks, but he invited the water and fertilizer trucks to dump “water and fertilizer” in the bamboo garden, because farmers generally believe that water and fertilizer are very fertile and can help crops grow, which can not only save fertilizer costs, but also It can also be regarded as an alternative organic cultivation, and the water and fertilizer industry is also very happy, so there is no need to enter the water and fertilizer factory set up by the government, and the follow-up processing fee can be exempted. But after being dumped several times by the water and fertilizer truck, my uncle found that the soil had turned into hard lumps, as shown in the photo below: Not only did the farmland not grow any grass, but the production of bamboo shoots dropped sharply, and many bamboos even began to wither and die...
This is because today's water and fertilizer are different from the water and fertilizer in the early days of simple folk customs. In addition to a variety of pathogenic bacteria mixed in the excrement, there is also a large amount of "oil", because the water and fertilizer truck will not only pump toilet waste, but also pump it. In addition to the oil in the restaurant, it is very difficult for the oil to be decomposed by microorganisms because free radicals will be generated after the oil is oxidized. In addition, the oil will also block air conduction, causing a large number of deaths of soil microorganisms, insects, earthworms, plants, etc.
