Converse circulation method for harnessing lake pollution

Abstract

A method for controlling lake pollution. Water flows to low places under natural conditions, and this invention uses the principle of circulation pump to send the polluted lake water to a high place, and then let it flow to a low place, which also achieves the purpose of circulating the water body. During the circulation of polluted lake water, a large number of living water molecules will be produced, and the newly produced living water molecules will decompose a certain amount of pollutants to achieve the effect of purifying water quality. It has been proved in experiments that a large amount of chemical oxygen demand COD, total nitrogen (TN), and total phosphorus (TP) have dropped to the lowest point, and cyanobacteria blooms have completely disappeared in the cycle.

Description

technical field [0001] The invention relates to a treatment method for lake pollution. It is especially effective for heavily polluted waters of lakes. Background technique [0002] At present, the three most polluted lakes in my country are: Taihu Lake, Chaohu Lake, and Dianchi Lake are all inferior to V-class water quality, which is unusable water quality. However, my country is a very water-deficient country in the world, and the per capita possession of water resources ranks No. The 110th place in the world. But we have nearly 16 billion cubic meters of water (the total of the three lakes), which cannot be used and also affects sightseeing. But the current treatment method takes a long, long time, and maybe it can’t be cured at all. Take Dianchi Lake in Kunming as an example: more than 30 years ago, the water body beside Dianchi Lake was crystal clear. At that time, Dianchi Lake had more than 20 waterways. The clear river flowed into Dianchi Lake, forming a good natura...

But we have nearly 16 billion cubic meters of water (the sum of the three lakes), which cannot be used, and it also affects sightseeing

But the current treatment method takes a long, long time, and maybe it can’t be cured at all. Take Dianchi Lake in Kunming as an example: more than 30 years ago, the water body beside Dianchi Lake was crystal clear. At that time, Dianchi Lake had more than 20 waterways. The clear river flowed into Dianchi Lake, forming a good natural circulation system. At that time, Dianchi Lake was really "a hundred boats competing for the flow, and fish and boats sing late". According to historical records, the aquatic products at that time, all kinds of fish, had an annual output of more than 10,000 tons
