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

[0033] Below in conjunction with accompanying drawing, further illustrate structure and working method of the present invention:

[0034] The lateral flow biological aerated filter-lateral flow constructed wetland combination system for the treatment and reuse of domestic sewage in green buildings is composed of a lateral flow biological aerated filter and a lateral flow constructed wetland.

[0035] see figure 1 , figure 2 , image 3 and Figure 4 , The lateral flow biological aerated filter mainly includes a regulating tank 2, a section A filling area 4, a transition area 5, a B section filling area 6 and an outlet area 7. The sewage enters the regulating tank 2 through the water inlet pipe 1, and then enters the packing area 4 of section A through the perforated plate 3. The packing frame in the packing area 4 of section A is filled with zeolite with a particle size of 10-15mm, and is arranged in a staggered manner. S-shaped water flow channel, so that most of the sewa...

Abstract

The invention discloses a side flow aeration biofilter-side flow artificial wetland combination system used for treating and reusing the domestic sewage of the green building. The system consists of two parts, namely a side flow aeration biofilter and a side flow artificial wetland, wherein the side flow aeration biofilter mainly comprises an adjusting tank, an A-section filler zone, a transitionzone, a B-section filler zone and an effluent zone; and the inside space of the side flow artificial wetland is divided to S-shaped gullies by parallel baffles which are arranged in a staggered manner. The combination technology has the following advantages of both the two water treatment technologies: the side flow aeration biofilter has high shock resistance and high and stable treatment efficiency; and the side flow artificial wetland has low operation cost and good water outlet effect, also has ecological effect and can be used to beautify the environment of the green building. Meanwhile,the combination technology can compensate the following weaknesses of each technology: by adopting the side flow artificial wetland, the weakness of the aeration biofilter that the removals of nitrogen and phosphorus are not complete; and by adopting the aeration biofilter, the problems of the artificial wetland that the artificial wetland is easy to block and the treatment effect is not stable in winter, can be solved.

Description

technical field [0001] The invention belongs to the technical fields of sewage treatment, environmental protection and green building, and specifically relates to the combined process of "lateral flow aerated biological filter - lateral flow constructed wetland" for treating green building domestic sewage, and the water quality after treatment can simultaneously meet the requirements of "Urban Sewage Recycling and Utilization" Requirements of "Water Quality of Urban Miscellaneous Water" (GB / T18920-2002) and "Water Quality of Urban Sewage Reuse and Landscape Environment" (GB / T18921-2002). Background technique [0002] When the shortage of water resources has become a serious problem facing the world, the reuse of sewage after treatment has become the consensus of the whole world. The treatment and reuse of domestic sewage in green buildings provides new "water sources" for areas with scarce water resources. For areas with abundant water resources, it can prevent and control p...
