Water treatment method for purifying sewage by use of microorganisms

Abstract

The invention relates to the water treatment field and specifically relates to a water treatment method for purifying sewage by use of microorganisms. The water treatment method is characterized by comprising at least the steps of arranging at least one biochemical bed in a water area to be treated and arranging a frame with a through opening on the biochemical bed. The water treatment method has the advantages that excellent microbial slow release effect can be produced, the microbial diversity in the water area is greatly increased, the reproduction and growth environment for the microorganisms is greatly improved and the influence of activity decline of the microorganisms in winter is counteracted, and the addition volume ratio of the biochemical bed relative to the water area to be treated is greatly lower than that of a filler in a conventional biochemical process.

Description

technical field [0001] The invention relates to the field of water quality treatment, in particular to a water treatment method using microorganisms to purify sewage, in particular to a water treatment method using slow release to release microorganisms to purify sewage. Background technique [0002] In today's society, due to the acceleration of urbanization, industrial pollution, pollution from rural livestock and poultry breeding, pollution from aquaculture residual bait and manure, and pollution from agricultural planting fertilizers, water habitats are degraded, and water quality and bottom quality are seriously polluted, which not only directly affects the The development of aquaculture has also brought adverse effects on the development of human living environment, agriculture and other industries. [0003] Due to the aggravation of water pollution and people's increasing attention to water habitats, the field of water treatment should also develop rapidly. At present...
