Embodiment 1

[0029] An artificial lake in Wuxi City covers an area of ​​5 mu. Due to the high temperature and lack of rain, the water level is lower than in previous years. A layer of blue-green foam with a fishy smell is formed on the water surface. There are many dead fish floating on the lake surface. The average nitrogen and phosphorus content of the lake water is as high as 3.0mg. / L and 0.11mg / L, algae have been distributed throughout the lake, far exceeding the standard of eutrophic lakes, seriously affecting the air quality and the quality of life of surrounding residents.

[0030] For above-mentioned artificial lake, adopted technical scheme of the present invention to control, concrete implementation steps are as follows:

[0031] (1) Put algicide into the artificial lake, first put in 20 parts of copper sulfate, copper sulfate is used to kill algae, after 5 hours, then put in 10 parts of polymerized alumina, used for polymerized alumina For the precipitation of algae and suspend...

Embodiment 2

[0039] A certain fish pond in Kaifeng City is surrounded by farmland, overuse of pesticides and chemical fertilizers, more than 60% of the pesticides and fertilizers are discharged into the fish pond along with the farmland drainage. In the hot summer weather, large-scale cyanobacteria suddenly appeared, and a large number of fish died. The test results showed that the nitrogen content was 0.9ppm, and the phosphorus content was 0.08ppm.

Abstract

The invention discloses a method for treating an algal turbid water body. The method comprises the following steps: killing algae by using copper sulfate, conducting flocculating and precipitating byusing polyaluminium oxide, pumping water into a precipitation tank, adding one selected from a group consisting of ferric salt, aluminum salt and calcium salt, further precipitating nitrogen and phosphorus in the water body, increasing the oxygen content of the water body, and conveying the precipitated water back to the water body. The above steps can reduce the nitrogen and phosphorus contents of the water body in a short time; and to achieve long-term good ecological balance, the biological purification effect of the water body itself needs to be improved, emergent aquatic plants are evenlyplanted on the periphery of the algal turbid water body, submerged plants are evenly planted at the bottom of the water body, and carnivorous fishes and benthic animals are evenly put into the waterbody. According to the invention, short-term treatment and long-term treatment are combined, water quality treatment and environmental beautification are combined, the water body is beautified while water quality is purified, the self-purification capacity of the water body can also be improved, and lasting and long-acting algae quantity control is achieved.

Description

technical field [0001] The invention relates to the field of water environment treatment, in particular to a treatment method for algal turbid water bodies. Background technique [0002] Algal turbid water is a kind of water pollution caused by excessive content of nitrogen, phosphorus and other plant nutrients. Due to the development of industry and the improvement of people's living standards, a large amount of industrial wastewater, domestic sewage, and plant nutrients in farmland runoff are discharged into slow-flowing water bodies such as lakes, reservoirs, estuaries, bays, etc., destroying the ecological balance of the water body, causing algae and other Plankton reproduced rapidly, the dissolved oxygen in the water decreased, the water quality deteriorated, and fish and other organisms died in large numbers. [0003] At present, the algae pollution of water bodies in our country is relatively serious, and the prevention and control of algae pollution is the most comp...
