Problems solved by technology

[0005] In the current existing technology, the compound microbial agent used to control the river is not proportioned according to the degree of pollution, but is described by the polluted river. The proportion of this compound microbial agent is not suitable for the case. The pollutants in river water cannot be treated in a targeted manner, resulting in the loss and waste of beneficial microorganisms

Embodiment 1

[0020] The compound microbial bacterial agent used for the treatment of lightly polluted river water includes compound microbial photosynthetic bacteria, yeast, Pseudomonas stutzeri, actinomycetes, denitrifying bacteria, Alcaligenes, and Bacillus subtilis. The composite microbial bacterial agent is composed of the following raw materials in weight percentage: 15% of photosynthetic bacteria, 5% of yeast, 15% of Pseudomonas stutzeri, 20% of actinomycetes, 15% of denitrifying bacteria, 15% of Alcaligenes %, Bacillus subtilis 15%.

[0021] A river in Meixi Town, Anxian County, Huzhou City, Zhejiang Province, underwent dredging and aquatic plant restoration in May 2017, but the water quality of the river still did not meet the standard. After sampling, the water quality index was determined: COD was 37mg / L, NH 3 -N is 3.2mg / L, TP is 0.7mg / L, dissolved oxygen content is 8.3mg / L, pH value is 7.85, and its CPI is 4.275, which belongs to lightly polluted river. In July, 2017, the comp...

Embodiment 2

[0025] Composite microbial agent for moderately polluted river water treatment, including composite microbial photosynthetic bacteria, Bacillus subtilis, nitrifying bacteria, denitrifying bacteria, Pseudomonas, Aeromonas. The composite microbial bacterial agent is composed of the following raw materials in percentage by weight: 15% of photosynthetic bacteria, 25% of Bacillus subtilis, 15% of nitrifying bacteria, 20% of denitrifying bacteria, 15% of Pseudomonas, and 10% of Aeromonas .

[0026] A certain river in Xiaofeng Town, An County, Huzhou City, Zhejiang Province, due to the surrounding farmland, the pesticides applied in the fields will enter the river water with the action of surface runoff in rainy days, and the river channel is affected by the mixed sewage of nearby residents all the year round, and the river water is relatively turbid , there is a layer of moss floating along the river, and the water quality index is determined after sampling: COD is 64mg / L, NH 3 -N ...

Embodiment 3

[0030]Composite microbial agents for the treatment of heavily polluted river water, including complex microorganisms Bacillus cereus, Bacillus subtilis, Acinetobacter awnii, Thiobacillus oxidans, lactic acid bacteria, yeast, actinomycetes, and denitrifying bacteria. The composite microbial bacterial agent is composed of the following raw materials in weight percentage: 15% of Bacillus cereus, 15% of Bacillus subtilis, 15% of Acinetobacter junii, 20% of Thiobacillus oxidans, 10% of lactic acid bacteria, and 5% of saccharomyces , Actinomycetes 20%,.

[0031] A certain river in Guangde County, Anhui Province, due to the lack of management all year round, a nearby factory secretly discharged untreated sewage into the rainwater pipe network and flowed into the river, causing the river to be black and smelly. After sampling the river water, its water quality index was determined: the COD of the river water was 145mg / L, NH 3 -N is 24mg / L, TP is 2.8mg / L, dissolved oxygen content is 2...

Abstract

The invention discloses a compound microorganism bacterium agent for treating river water at different pollution levels. The compound microorganism bacterium agent is characterized in that the river water at different pollution levels is classified through organic integrated evaluation method CPI. The compound microorganism bacterium agent for treating river water with mild, intermediate and serious pollution is prepared specifically and acts appropriately to the situation, thus the microorganism loss and waste can be avoided, and the economic cost is saved while the microorganism utilizationefficiency and the treatment effect are improved. According to the compound microorganism bacterium agent, strains mutually coordinate and act together; organic substances are decomposed by oxidation-reduction and fermenting and other ways; the compound microorganism bacterium agent is capable of quickly and stably covering the ecological niche of an aquatic ecosystem after being launched into water, thus a dominant bacterial community of beneficial microorganism can be formed, and the growth and reproduction of harmful microorganisms can be inhibited.

Description

technical field [0001] The invention belongs to the field of biotechnology treatment of polluted rivers, and in particular relates to a composite microbial bacterial agent used for treatment of rivers with different pollution degrees. Background technique [0002] Rivers play an important role in the process of urban development, not only providing water for the city, but also an important channel for the city's external traffic, which has an important and far-reaching impact on the work and life of urban residents. However, the rapid economic development and rapid population expansion lead to more and more pollution of urban rivers. Pollution from point sources and non-point sources destroys the aquatic ecological balance of rivers, and the water quality of urban rivers shows different degrees of pollution. The main pollution factors exceeding the standard are organic matter, ammonia nitrogen and total phosphorus. [0003] Microbial remediation technology, as a new type of...
