Abstract

The method of sewage processing has high nitrogen-phosphorus disloading ratio. It includes following process steps: pretreatment is to make sewage will be processed pass through grille to get rid of impurities; precipitating treatment is to do precipitating to the pretreated sewage in sedimention tank to get rid of grits; ecological filtering treatment is to send the sewage precipitation processed into worm lizard tower-type ecological filter to make the processed sewage reaching standard.

Description

technical field

[0001] The invention belongs to the technical field of sewage treatment, in particular to a sewage treatment method using an ecological filter and a special earthworm tower ecological filter. Background technique

[0002] Vermibiofi1ter is a treatment technology for domestic sewage that was first developed in France and Chile in recent years. 【1-4】 . This technology is designed based on the ecological functions of earthworms such as improving soil water permeability and promoting the decomposition and transformation of organic matter.

[0003] The use of biological filters to treat organic sewage is a commonly used sewage treatment method. In this process, the biological purification of water is combined with physical filtration, that is, the sewage is first treated by microbial aerobic and anaerobic fermentation in the water to degrade and transform the organic matter in it, and then it is filtered to achieve the purpose of sewage purification. Purpose. ...
