Problems solved by technology

[0005] However, at present, the cost of sewage reuse is relatively high due to technical and scale problems, and the cost of some small-scale sewage reuse projects even exceeds the price of tap water
Tap water is a direct substitute for sewage reuse, which greatly weakens the competitive advantage of sewage reuse

Embodiment Construction

[0036] Below in conjunction with accompanying drawing, further illustrate structure and working method of the present invention:

[0037] This SBR+constructed wetland combined treatment system is composed of SBR treatment device and constructed wetland treatment device;

[0038] see figure 1 , figure 2 , image 3 and Figure 4 , The SBR treatment device includes an SBR tank, a water inlet system, an aeration system, a drainage system, a mud discharge system and automatic control equipment. The sewage enters the SBR pool through the water inlet pipe 1, and the air pipe 4 is arranged in the pool through the elbow 7, and a certain distance is maintained between the bottom of the pool and the bracket 9 to facilitate the normal operation of the aeration system, and the outlet water of the SBR pool enters the constructed wetland through the outlet pipe 2 for treatment System, the remaining sludge is discharged through the sludge discharge pipe 3, the water intake of the system ...

Abstract

The invention provides an SBR+ artificial wetland combined treatment system for domestic sewage recycling. The system consists of an SBR treatment device and an artificial wetland treatment device; the SBR treatment device comprises an SBR tank, a water inlet system, an aeration system, a drainage system, a sludge discharge system and automatic control equipment; and the artificial wetland treatment device consists of a three-level side wetland bed, a natural reoxygenation tank and a stabilization pond. The SBR and artificial wetland combining technology has the advantages of two water treatment techniques. The SBR has the advantages of strong impact load resistance, high automatic control degree and simple operation; and the artificial wetland has the advantages of low operation cost, simple maintenance, ecological effect, greening function, and capacities of beautifying the environment and combining the residential landscape. Meanwhile, the SBR and artificial wetland combining technology can overcome respective defects of the two techniques, shorten the aeration time of the SBR system, and reduce the energy consumption thereof. The artificial wetland can make up the nitrogen and phosphorus removal effect in the SBR; and the SBR system can solve the problem that the artificial wetland system has poor treatment effect in winter, effectively prevents the blockage of the artificial wetland, and reduces the occupied area of the artificial wetland.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and specifically relates to the "SBR+constructed wetland" combination process for treating domestic sewage in residential quarters. The water quality after treatment must meet the "Landscape Water Standard" (GB / T18921-2002) at normal temperature (T≥15°C). Scenery requirements, at low temperature meet the toilet flushing requirements in the "Urban Miscellaneous Water Quality Standards" (GB / T18920-2002). Background technique [0002] When the shortage of water resources has become a serious problem facing the world, it has become the consensus of the whole world to properly treat sewage for reuse and water recycling. Residential sewage treatment and reuse provides new "water sources" for water-scarce areas. For areas with abundant water resources, it can prevent and control pollution and reduce the pressure on pipe networks and sewage treatment. The establishment of decentralized sewage t...
