A solar septic tank device and treatment process for domestic sewage pretreatment

Abstract

The invention discloses a solar septic tank apparatus and treatment process for pretreating domestic sewage and applies to small-scale distributed domestic sewage, wherein the septic tank apparatus comprises a solar system and a septic tank, the septic tank comprises a first compartment, a second compartment and a third compartment divided by a first partition and a second partition, the first compartment is an inflow compartment, the second compartment is a transition compartment, and the third compartment is a filter compartment; in the first compartment, provided are heating plates in multiple tiers, each heating plate is provided with at least one circle of uniformly distributed pores; the third compartment is provided with a second inflow pipe and a filter layer, a water inlet of the second inflow pipe is connected to a second water inlet, and a water outlet of the second inflow pipe is positioned at the lower end of the filter layer. Compared with traditional septic tanks, the invention is insusceptible to ambient temperature, anaerobic digestion is enhanced by controlling a temperature field and a flow field, and degrading ability of microorganisms and pollution removal efficiency can be improved.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to an anaerobic domestic sewage pretreatment device and treatment process utilizing solar energy. Background technique [0002] 1. In the existing domestic sewage treatment, especially in decentralized treatment facilities, the use of septic tanks is relatively common. It is a pretreatment facility that uses the principle of sedimentation and anaerobic fermentation to remove suspended organic matter in domestic sewage. It belongs to Primary life processing structures exist widely in both urban and rural areas. [0003] 2. The treatment of decentralized domestic sewage has increasingly become the focus of environmental protection work. The current centralized domestic sewage treatment process is complicated, the reaction process is long, the operation is complicated, and the energy consumption is relatively high. It is not suitable for the decentralized domestic sewage treatm...

AI Technical Summary

Problems solved by technology

At present, the centralized domestic sewage treatment process is complicated, the reaction process is long, the operation is complicated, and the energy consumption is relatively high. It is not suitable for the decentralized domestic sewage in rural areas and other areas.

[0004] 3. Although the existing septic tank can treat this kind of scattered domestic sewage, the treatment effect is not good, which increases the difficulty and cost of subsequent treatment
