Abstract

The invention belongs to the technical field of sewage treatment, and discloses a compound microorganism water purifying agent and an application thereof. The compound microorganism water purifying agent comprises a microorganism and a carrier, the microorganism comprises clostridium, saccharomycetes, micrococcus, acidobacteria, bacteroid, rhizobia, burkholderia cenocepacia, thiobacillus, opitutae, hydrogenophilales, lysobacter, brevundimonas, xanthomonas, comamonas, rhodocyclus and rhodospirillum, and the microorganism is fixed onto the carrier. The compound microorganism water purifying agent has high activity and is high in treatment efficiency, long-time domestication and selection is omitted, a short stable period is achieved in a treatment system, strains in the compound microorganism water purifying agent are cooperatively interact, utilization and metabolic decomposition of nutrient substances in water by the microorganism are facilitated, and COD (chemical oxygen demand) and ammonia nitrogen are efficiently reduced.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a composite microbial water purifying agent and its application. Background technique [0002] China is a big agricultural country. Agriculture is in a basic position in the industrial structure, and the proportion of GDP is also in an important position. Moreover, the large proportion of agricultural population increases the demand for water resources and produces a large amount of sewage. With the acceleration of rural urbanization, the discharge of domestic sewage in rural areas has greatly increased, and the rural population is relatively scattered. There is no unified sewage collection pipe network, and centralized treatment cannot be carried out, resulting in a large amount of untreated sewage being directly discharged into nearby natural water bodies. Thereby causing serious water pollution. The pollutant content of domestic sewage in rural areas is ...
