Method for controlling water pollution

Abstract

The invention provides a method for controlling water pollution. The method comprises the steps of (1) spraying a mineral carrier microorganism onto a water surface by a microbial precipitation technique, and sinking the mineral carrier microorganism to a bottom of a water sludge layer, wherein the mineral carrier microorganism is prepared from, by weight, 2%-4% pf yeast, 6%-8% of lactic acid bacteria, 51%-53% of actinomycetes, 24%-26% of photosynthetic bacteria, 7%-9% of denitrifying phosphorus accumulating bacteria and 4%-6% of rhodococcus erythropolis; (2) preparing a carrier bio-base and putting into a water body; (3) installing an aeration device 10-30 mm from the water sludge layer. The mineral carrier microbial with unique proportion of microbial strains and the organic combinationof a carrier bio-base technology are adopted to effectively decompose and pollute a polluted organic matter in a sediment into carbon dioxide, water and the like, a river mud layer is lowered insteadof dredging, and the water body can be repaired in a short time.

Description

technical field [0001] The invention relates to the technical field of treatment of river polluted water bodies, in particular to a method for controlling water body pollution. Background technique [0002] At present, the water quality of major river basins in my country has not undergone fundamental changes, and the situation of water pollution prevention and control is still very severe. From the water quality of the national control sections in the past three years, it can be found that the proportion of water quality inferior to Class V has been declining year by year, but at the same time, the proportion of water quality of Class I has also declined. In 2016, the proportion of water quality of Class IV and worse than Class IV still has With a high proportion of 32.3%, the situation of water pollution prevention and control is still very severe. [0003] At present, the treatment methods for surface water basins such as rivers, lakes, and reservoirs in my country basic...

[0002] At present, the water quality of major river basins in my country has not undergone fundamental changes, and the situation of water pollution prevention and control is still very severe.

From the water quality of the national control sections in the past three years, it can be found that the proportion of water quality inferior to Class V has been declining year by year, but at the same time, the proportion of water quality of Class I has also declined. In 2016, the proportion of water quality of Class IV and worse than Class IV still has With a high proportion of 32.3%, the situation of water pollution prevention and control is still very severe

[0003] At present, the treatment methods for surface water basins such as rivers, lakes, and reservoirs in my country basically adopt municipal sewage interception engineering methods, dredging and changing water, adding microbial strains and planting aquatic plants, etc. These methods are very beneficial to water purification and can be invested heavily , the purification process is single, once the water body is polluted by external sources, it will deteriorate again, and it will not cure the symptoms
