Problems solved by technology

However, such as anaerobic + aerobic + wetland method, this method has disadvantages such as high energy consumption, unstable effluent quality, and limited effect of nitrogen and phosphorus removal.
In addition, the MBR / constructed wetland process is also very competitive in the field of decentralized sewage treatment and reuse due to its high sludge concentration and stable effluent quality, but its high operating costs limit its wide application

Embodiment Construction

[0032] The preferred technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] Such as figure 1 As shown, a kind of solar rural domestic sewage trickling filtration treatment system of the present invention includes a grid regulating tank 1, a trickling filter tank 2, and an artificial wetland 3 connected in sequence by water pipes;

[0034] The grid adjustment pool 1 is provided with a water inlet pipe 4, and a water tank is arranged near the water inlet pipe 4 in the grid adjustment tank 1. There is a grid 5 in the water tank, and a reserved hole 6 is provided at the bottom of the water tank, and the waste water passes through the grid 5. Filtration flows from the reserved hole 6 to the regulating pool. The grid regulating pool 1 is also provided with a lift pump 7. A flowmeter well 8 is arranged above the lift pump 7. An electromagnetic flowmeter is installed in the well. The lift pump 7 and the fl...

Abstract

The invention discloses a solar rural domestic sewage trickling filtration system and a use method thereof. The system comprises a grid adjusting tank, a trickling filter and a constructed wetland, and collected rural domestic sewage is purified step by step. Compared with the prior art, the system has the advantages that a storage battery supplies energy by the aid of a solar panel, energy sources are saved, running cost is reduced, the structure is simple, pumice stone fillers are arranged in the trickling filter, COD (chemical oxygen demand), ammonia nitrogen and total nitrogen and total phosphorus removal rate is high, water treatment effects are good, oxygen is supplied for the trickling filter by natural ventilation, an aerator is omitted, investment cost is reduced, enhanced phosphorus removal can be realized by modified limestone ceramsites in a constructed wetland treatment area, nitrogen and phosphorus adsorption effects are remarkable, and the whole project is simple in structure, convenient in construction, stable in running and low in running cost.

Description

technical field [0001] The invention relates to a sewage treatment system and method, in particular to a solar-powered rural domestic sewage trickling filtration treatment system and its use method, belonging to the field of rural domestic sewage treatment. Background technique [0002] In recent years, my country's rural economic construction has developed rapidly, and the level of urbanization has continued to increase. However, the discharge of domestic sewage in rural areas has also increased, and the water quality pollution has gradually deteriorated. The problem of rural water environment pollution has become more and more prominent. The main characteristics of rural domestic decentralized sewage are small water volume and large fluctuations, and high nitrogen and phosphorus content in sewage, which can easily cause eutrophication of water bodies. [0003] At present, the common rural decentralized domestic sewage treatment methods mainly use anaerobic biological treat...
