Abstract

The invention discloses a compound microorganism water-purification agent and a preparation method thereof. The water-purification agent is composed of bacillus megaterium, bacillus circulans, rhodopseudomonas palustris, nitrobacter and lactobacillus plantarum. In a culture process, after all strains are cultured separately, mixed culture of the strains is carried out according to the ratio of all strains, so that the finished product is obtained finally. The density of each of five strains in the agent can reach 7-10*10<8>/ml/. By adopting the method provided by the invention, all strains can grow effectively, so that effective microorganism concentration of the compound microorganism water-purification agent is ensured; after the compound microorganism water-purification agent is fed into recycled water receiving water, the effective concentration of microorganisms is high, various microorganism strains play corresponding roles to effectively remove COD, ammonia nitrogen, TN, TP and other pollutants in water originally, particularly, the removal rate for TN is high, and the compound microorganism water-purification agent can change chromaticity and odor of water, and has an obvious water purification effect.

Description

technical field [0001] The invention belongs to the field of environmental protection and ecological restoration, and more specifically relates to microbial water purification technology, in particular to a composite microbial water purification preparation, preparation method and application. Background technique [0002] Due to long-term over-exploitation and utilization, many rivers, lakes and groundwater resources are almost exhausted, and surface water is mostly polluted, which not only reduces the use function of water bodies, but also further aggravates the contradiction of water resource shortage. In order to solve the water shortage problem in modern cities, the search and development of the second water source has become an important topic. Recycled water resources are regarded as a new water source by many countries and regions in the world, and the reuse of regenerated water resources is also called "the second water source of the city". An effective way for sus...
