The left side area is used for residence, primary treatment and sedimentation of sewage, the supernatant passes through the water flowing weir to enter the right side area for residence and sewage treatment again, the water flowing weir not only can intercept water bodies and ensure that the supernatant flows into the right side area, but also can be used as a living carrier of small-sized aquatic plants, algae and the like, and the efficiency of the facultative pond water treatment is improved; the aeration pond is provided with the water inlet baffle, so that the vertical centralized inflow of the water body is facilitated, the mixing of the water inlet and the water body in the aeration area is reduced, and the treatment efficiency is effectively improved; biological filler walls are arranged on the four walls of the aeration pond, so that the water treatment effect is improved by using a biomembrane method; the aeration pond is designed with 2 groups of U-shaped aeration branched pipes, and the U-shaped mode is beneficial to reducing aeration resistance in the pipes and reducing wind power consumption. The plurality of aeration heads on the U-shaped aeration branched pipes are distributed in a staggered manner, so that the fluidity and oxygen enrichment capability of the water body of the aeration tank can be improved; the zigzag aerobic pond has long water flowing distance, effectively increases the flowing area and the detention time of the water in the aerobic pond, and the zigzag aerobic pond body is obliquely built, thereby being beneficial to the natural flowing of the water; the water body of the treatment system naturally flows, and a pump is not required to do work; the device carries out sewage treatment in an ecological environment-friendly mode, and the power supply is provided by a solar power generation system; the device can also be used for front-end treatment of river and lake water.
The device constructs facultative pond, aeration pond, good oxygen pond into integrated processing system, compact structure, area are little, utilize water head between each pond to advance water and go out water, utilize solar power system to provide electric power, utilize small-size aquatic plant, algae, microorganism etc. in the pond to carry out biochemical degradation layer upon layer, finally reach high-quality water outlet index. The raw materials of the internal structures of the combined device mostly adopt natural gravels, cobbles, matrix particles and the like as carriers, and biological filler walls and U-shaped aeration pipes are adopted in an aeration pond for biological membrane aeration treatment, so that the treatment mode is ecological and environment-friendly, energy-saving and emission-reducing, and the ecological treatment is carried out on the inflow water by using lower economic cost.
