Abstract

The present invention belongs to a sewage purifying biomass pool technical field. The biomass pool body is an integrated ring structure, which consists of a first-class anaerobic room, a second-class anaerobic room, a first-class biological filter room and a second-class biological filter room. A water inputting mouth is arranged in each room for connecting a pipeline and two neighboring rooms. A baffle is arranged in each room. A water outputting mouth, which is communicated to a ring anaerobic pool, is arranged in the second-class biological filter room. The bottom of the pool adopts a lean structure, which is used for easily collecting sewage sludge. The present invention adopts a composite materials integrated design. The risk of leaking is reduced; the equipment is compact; the occupied acreage is small; the production efficiency is high; industrialized production is easily to be realized; the scene operating time is reduced and the installing and constructing are convenient. The present invention has the advantages of high strength, corrosion resistant, low thermal conductivity, and good heat preserving effect and long service time and so on.

Description

technical field [0001] The invention relates to a biogas pond for purifying domestic sewage. Background technique [0002] At present, the biogas digesters built according to the design plan in the existing standard atlas 90SS-1 of domestic sewage purification biogas digesters adopt brick-concrete structure and consist of multiple treatment ponds. The structure, construction and technology of this biogas digester can no longer meet the needs of social development. First of all, due to many problems in design, construction, use, management, etc., more than 95% of the biogas digesters began to leak seriously after 1-2 years of use. Because they were not taken seriously, the leakage of biogas digesters seriously polluted underground drinking water. Water sources and urban underground water supply pipelines, more serious ones cause buildings to tilt to varying degrees. The on-site construction of this biogas digester takes a long time, and the labor intensity is high, which al...
