Solar septic tank apparatus and treatment process for pretreating domestic sewage

Abstract

The invention discloses a solar septic tank device for pretreatment of domestic sewage and a treatment process thereof, which is suitable for small-scale distributed domestic sewage. Wherein the septic tank device includes a solar energy system and a septic tank, and the septic tank includes a first cell, a second cell and a third cell separated by a first partition and a second partition, the first cell It is a water inlet cell, the second cell is a transition cell, and the third cell is a filter cell; a multi-layer heating plate is arranged in the first cell, and at least one circle of evenly distributed heating plates is provided on each layer of the heating plate A small hole; a second water inlet pipe and a filter layer are arranged on the third compartment, the water inlet of the second water inlet pipe is connected to the second water inlet, and the water outlet of the second water inlet pipe is located in the filter bottom of the layer. Compared with the traditional septic tank, the invention is not limited by the influence of the environment temperature, and the effect of anaerobic digestion is enhanced through the regulation and control of the temperature field and the flow field, and the degradation ability of microorganisms and the removal efficiency of pollutants are 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
