One-body domestic-sewage treatment system

Abstract

Provided is a one-body domestic-sewage treatment system for treating sewage in daily life. The system comprises: a biological treatment apparatus including an anoxic pool, an aerobic pool and a sedimentation pool which closely abut against each other, wherein one overflow orifice is arranged between the anoxic pool and the aerobic pool, the other overflow orifice is arranged between the aerobic pool and the sedimentation pool; and a membrane treatment apparatus including a membrane treatment pool of original water, a membrane treatment assembly and a water producing pool. The combination of biological treatment with membrane treatment is adopted in the invention, so that excurrent water can reach a water quality standard of drinking water. Apparatuses in the invention combined with each other closely can be integrated in a container and loaded on a trailer to move instantly, so transport and installation of the system are convenient. Sewage can be treated conveniently in areas which are remote, far away from a sewage drain pipeline network of the city and not suitable for building a sewage treatment factory. In particular, the system in the invention is suitable for treating domestic sewage in tourism areas, scenic spots, villa quarters, resorts, sanatoriums, armies, countrysides, desert areas, wellsites, etc.

Description

technical field

[0001] The present invention is a sewage treatment system for treating daily sewage, especially for an integrated domestic sewage treatment system that is far away from urban sewage pipe networks and is not suitable for building sewage treatment plants locally. Background technique

[0002] Some remote areas far away from urban sewage pipe network and not suitable for building sewage treatment plants. The sewage in these areas cannot be treated centrally, but it cannot be discharged directly. Such as tourist areas, scenic areas, villa communities, resort areas, nursing homes, troops, rural areas, desert areas, well sites, etc. Correspondingly, an integrated domestic sewage treatment system is required, and the sewage treated by the system is required to meet the secondary water or drinking water standard.

[0003] The traditional domestic sewage treatment system consists of two parts: primary treatment and secondary treatment. The primary treatment mainly ...

Embodiment Construction

[0017] Examples of the present invention figure 1 Shown: Integrated domestic sewage treatment system, including biological treatment device and membrane treatment device, biological treatment device includes anoxic tank 3, aerobic tank 4 and sedimentation tank 5 close together, anoxic tank 3 to aerobic tank 4 is provided with an overflow hole, and the aerobic tank 4 to the sedimentation tank 5 are provided with overflow holes. A thruster is installed at the bottom of the anoxic pool 3, and its function is to prevent the mixed solution in the anoxic pool from settling. A microporous aeration pan is installed at the bottom of the aerobic pool 4, and a Roots blower is arranged outside the microporous aeration pan to aerate the aerobic pool. A submersible sewage pump is installed at the end of the aerobic pool 4, and the sludge in the aerobic pool 4 is returned to the anoxic pool 3 through the submersible sewage pump. A submersible sewage pump is installed at the bottom of the s...
