Abstract

The invention provides a sewage treatment device and a sewage purification method, and relates to the field of sewage purification. The sewage treatment device comprises an anoxic tank. A plurality offlexible ropes which extend along the length direction of the anoxic tank and are longer than the anoxic tank are arranged in the anoxic tank. A plurality of flexible ropes are arranged at intervalsin the width direction and the depth direction of the anoxic tank. A biological membrane filler is arranged on each flexible rope in a penetrating manner and is arranged on the flexible rope at intervals. When the adjacent flexible ropes in the pool width direction and the pool depth direction perform relative reverse motion, the biological membrane fillers on the adjacent flexible ropes can collide with each other. The water distribution lattice wall is arranged at the water inlet end of the anoxic tank, is provided with water distribution holes with different hole diameters, and is used forenabling liquid in the anoxic tank to generate oscillation and enabling sludge mixed in the anoxic tank to be not settled. According to the invention, the problem of energy consumption caused by uniform distribution of the biofilm filler can be solved, the biofilm filler can be distributed more uniformly, and the biofilm in the biofilm filler can be updated in time.

Description

technical field [0001] The present application relates to the technical field of sewage treatment, in particular, to a sewage treatment device and a sewage purification method. Background technique [0002] The essence of the sewage biofilm treatment method is to make microorganisms such as bacteria and fungi and micro-animals such as protozoa and metazoans attach to the filter material or some carriers to grow and multiply, and form a film-like biological sludge on it. --Biofilms. The contact between sewage and biofilm, the organic pollutants in the sewage, as nutrients, are taken up by the microorganisms on the biofilm, the sewage is purified, and the microorganisms themselves are multiplied. [0003] At present, the sewage treatment method commonly used in sewage plants is to add biofilm filler in the activated sludge anoxic tank. The arrangement of biofilm fillers can be divided into two types: mobile type and suspension type. When the mobile biofilm filler is applied...
