Embodiment 1

[0036] About 1200m in a ditch in Changping District, Beijing 2 In natural waters, the downstream water is often cut off, and dams are built to block it. The upstream waters do not flow. There are many sewage outfalls in the natural waters, and no one cleans them up. At present, it is in a black and odorous state in summer, which seriously affects the nearby residents. Although there are recreational dams along the coast, but because the water quality is too smelly, no one cares.

[0037] The biological water purifying agent of the present invention is used to treat the water body in this area, and the specific formula is according to parts by weight: 10 parts of yeast, 15 parts of bacillus, 20 parts of photosynthetic bacteria, 25 parts of nitrifying bacteria, 25 parts of denitrifying bacteria, and 25 parts of sulfur bacteria. 25 parts, 20 parts of sulfur bacteria, 6 parts of accessories. The auxiliary materials described therein include sodium carboxymethyl cellulose, ammoniu...

Embodiment 2

[0043] About 1800m from a polluted artificial lake in Cangzhou, Hebei 2 The water area is often in a dilapidated and dilapidated park, and no one has cleaned it up. At present, it is in a black and smelly state in summer, which seriously affects the lives of nearby residents. However, due to the smelly water quality, few people come here for leisure.

[0044] The biological water purifying agent of the present invention is used to treat the water body in this area, and the specific formula is according to weight parts: 12 parts of yeast, 18 parts of bacillus, 20 parts of photosynthetic bacteria, 25 parts of nitrifying bacteria, 25 parts of denitrifying bacteria, sulphur bacteria 25 parts, 25 parts of sulfur bacteria, 8 parts of accessories. The auxiliary materials described therein include sodium carboxymethyl cellulose, ammonium sulfate and ammonium chloride, and the weight ratio of the three is 1:1:1.

[0045] Specific use method: When implementing the treatment plan, mix e...

Abstract

The invention relates to a combined formula of a biological purifying agent for treating black and odorous water bodies or surface water of eutrophicated rivers and lakes and a using method. The biological purifying agent is mainly used for treating black and odorous and eutrophicated rivers and various water bodies caused by over-standard emission of organic pollutants or nutrient salts such as nitrogen and phosphorus. The product has the outstanding advantages that the product is formed by directionally inducing strains to grow, and has the functions of effectively reducing harmful algae ina water body, reducing bottom mud, reducing ammonia nitrogen and the like.

Description

technical field [0001] The invention relates to a microbial water purifier for treating black, odorous and eutrophic rivers, lakes and other water bodies. The invention especially has obvious manifestations in reducing water turbidity and ammonia nitrogen content and inhibiting algae growth. Background technique [0002] With the rapid development of today's society and economy, people's living standards are improving day by day, and environmental problems are becoming more and more serious. The pollution of rivers and lakes not only affects the balance of water ecology, but also threatens the safety of human drinking water. The root cause of river and lake pollution is that the amount of pollutants in the water body exceeds its own water purification capacity. The high pollutant concentration makes the water quality continue to deteriorate. Various treatment plans have little effect. Sewage is directly discharged into rivers and lakes, which increases the difficulty of rive...
