Problems solved by technology

[0005] However, due to the technical and scale limitations of domestic sewage reuse, the cost of small-scale sewage reuse is relatively high, and even the cost of reuse in some areas exceeds the price of tap water, seriously weakening the competitive advantage of reused water

Embodiment Construction

[0029] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0030] The present invention is composed of an upflow biological aerated filter and a horizontal subsurface constructed wetland, both of which together form a green building domestic sewage reuse system; after domestic sewage is pretreated, it enters an upflow biological aerated filter for pretreatment. Treatment, the effluent enters the horizontal subsurface flow artificial wetland for advanced treatment, and the effluent is reused for green buildings after treatment.

[0031] Such as figure 1 As shown, the upflow biological aerated filter mainly includes the supporting layer 4, the filling area 5 of section A, the filling section 6 of section B and the water outlet area.

[0032] The sewage enters the water distribution buffer chamber through the water inlet diversion pipe 1, enters the supporting layer 4 through the filter plate 2, and the aeration pipe 3...

Abstract

The invention discloses a reclaimed water treatment system combining an upflow aerating biological filter with horizontal underflow artificial wetland. The system consists of the upflow aerating biological filter and the horizontal underflow artificial wetland; the upflow aerating biological filter comprises a water inlet guide tube positioned at the bottom of the filter; a filter plate, a supporting layer, an A section filler area, a B section filler area and a water outlet area are sequentially arranged above the water inlet guide pipe; a communicating water pipe is mounted on the water outlet area, and communicated with a regulating tank of the horizontal underflow artificial wetland; an aerator pipe is led out of the supporting layer; the regulating tank and a matrix area parallel to the regulating tank are arranged at the lower layer of the horizontal underflow artificial wetland; the matrix area sequentially comprises a macadam area, a steel slag area, a zeolite area and a water outlet gravel area from left to right; the water outlet gravel area is equipped with a water outlet pipe; and a soil covering layer and aquatic plants are arranged at the upper layer of the horizontal underflow artificial wetland. With the adoption of the system, on-site treatment and utilization of sewage are achieved; the sewage treatment process flow is simplified; and operation and management costs are lowered.

Description

technical field [0001] The invention belongs to the technical fields of sewage treatment, green building and environmental protection, and in particular relates to a reclaimed water treatment system. Background technique [0002] Facing the depletion of fresh water resources, saving water is the premise and key to realize the optimal allocation and sustainable use of water resources. Reclaimed water reuse technology reduces the amount of water that must be obtained from the environment to meet water requirements, which is beneficial to the natural water volume; at the same time, it also reduces the pollutants discharged to the environment, which is beneficial to the environmental water quality. The implementation of decentralized sewage reuse devices in green buildings not only reduces the pressure of sewage treatment, but also facilitates the reuse of reclaimed water. [0003] According to the requirements of the "Twelfth Five-Year Plan", by 2015, my country's urban sewage...
