Embodiment 1

[0019] Specific process such as figure 2 As shown, the implementation site is a certain place in northern Jiangsu, Jiangsu Province. The anaerobic hydrolysis + micro-dynamic aerobic integrated pool adopts a glass fiber reinforced plastic cylindrical structure. After being treated by septic tanks, the domestic sewage in the residential area is discharged into the regulating tank at the front end of the integrated pool, and then enters the anaerobic hydrolysis section from the bottom through the water collection system at the upper end of the regulating pool. Then it enters the aerobic section from the bottom. The aerobic section is equipped with spherical packing and a jet aerator. After the upper part collects water, it enters the secondary sedimentation tank through the guide tube. The secondary sedimentation tank is equipped with a submersible sewage pump with a power of 0.55KW. Connect the jet aerator and regulating tank at the front end. Rely on the pump for jet aeration...

Embodiment 2

[0021] Specific process such as figure 2 As shown, the implementation site is a place in southern Jiangsu, Jiangsu Province. The anaerobic hydrolysis + micro-dynamic aerobic integrated pool adopts a steel concrete structure, and the landscape green space is designed as a submerged middle-periphery-direct current water distribution, with a processing capacity of 50t / d. The domestic sewage in the residential area is discharged into the small river. The water of the small river enters the anaerobic hydrolysis tank at the front end of the integrated pool after being lifted. The anaerobic water stage is equipped with combined elastic fillers. The section is equipped with combined elastic packing and a jet aerator. After the upper part of the aerobic section collects water, it enters the secondary settling tank through the guide tube, and the sludge from the secondary settling tank enters the sludge well. The sludge well is equipped with a 0.55KW power The submersible sewage pump i...

Abstract

The invention discloses a micro-power dispersion type domestic sewage treatment process. A device for implementing the process flow mainly comprises a regulating pond (optional), an anaerobic hydrolysis pond, an aerobic biochemical pond, a secondary sedimentation pond, a sludge well (optional), a clear water pond and landscape green land, wherein all the biochemical ponds are integrated ponds; and the landscape green land is of undercurrent type. Only a low-power pump is arranged in the entire process; aeration and sludge reflow are realized through the pump and a jet aerator; a better sewage treatment effect is achieved under the micro-power condition; and then deep treatment of the wastewater is realized through the landscape green land and the environment is beautified. The actual running results show that the process has the advantages of high denitrogenation and dephosphorization efficiency, good treatment effect, low energy consumption, less remaining sludge, low investment and operation cost, small occupied area and the like and is worthy of popularization and application.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and specifically refers to a method for performing microdynamic and low-cost treatment of domestic sewage by using a combined process of anaerobic hydrolysis-microdynamic aerobic-landscape green space. Background technique [0002] With the centralized treatment of large-scale urban domestic sewage, more and more attention has been paid to the pollution of domestic sewage discharged from scattered population settlements (rural areas or communities, etc.) or activities (highway service areas or resort villages, etc.). Sewage treatment processes or devices are not suitable for this kind of decentralized domestic sewage due to economic, management and efficiency issues. It can be seen from the literature review that the buried non-powered or micro-powered sewage treatment processes and equipment mainly used in China have certain advantages in treating them. But there are also some common p...
