Problems solved by technology

[0005] At present, the organisms commonly used in biological sewage treatment are microbial strains. Although the process is mature, it has insurmountable shortcomings. It has low treatment efficiency and poor impact resistance for most industrial sewage, especially high-concentration and refractory organic sewage and high-ammonia nitrogen sewage. ; Especially the wastewater produced by natural gas power generation has high content of organic matter, ammonia, and nitrogen, and it is difficult to efficiently degrade toxic and harmful organic matter, nitrogen, and phosphorus with simple strains
For example, the patent application document with application number 201010249613.0 discloses a compound high-efficiency microbial preparation for enhancing efficiency of sewage treatment plants, which cannot efficiently degrade harmful substances in sewage, and there is no report on the transparency of treated sewage water.

Description

technical field [0001] The invention relates to a sewage treatment agent, more specifically, the invention relates to a biological sewage treatment agent used for natural gas power generation sewage treatment. Background technique [0002] Natural gas is an efficient energy source. The calorific value of natural gas is 2.5 times that of artificial pipeline gas. Using natural gas to generate electricity can alleviate energy shortages, reduce the proportion of coal-fired power generation, and is an effective way to reduce environmental pollution. The treatment methods for sewage generated in natural gas power generation include physical treatment, chemical treatment and biological treatment. Physical treatment is the most primitive and simple water treatment method, which recovers insoluble suspended pollutants in sewage through physical separation. , This separation can be divided into gravity separation, centrifugal separation and sieve retention separation. This method can...
