Abstract
The invention provides a composite distributed rural sewage treatment system, which comprises a grating tank, a collection hydrolysis tank, a wetland earthworm tank, an algae tank and an artificial wetland, wherein the grating tank, the collection hydrolysis tank, the wetland earthworm tank, the algae tank and the artificial wetland are sequentially communicated through pipelines, the wetland earthworm tank is provided with a water distribution pipe, an earthworm filter layer, a soil layer, a filter material layer and a gravel layer from top to bottom, the water distribution pipe is communicated with the water outlet pipeline of the collection hydrolysis tank, the water outlet of the water distribution pipe is arranged above the earthworm filter layer, the water outlet of the wetland earthworm tank is arranged below the gravel layer of the wetland earthworm tank, the earthworm filter layer comprises earthworms and a first filter material, the first filter material comprises a celluloseplant material, a vertically suspended algae hanging net is arranged in the algae tank, algae are attached to the algae hanging net, and an aeration device is further arranged in the algae tank. Thecomposite distributed rural sewage treatment system disclosed by the invention is simple and reasonable in structure and low in operation cost, and has good removal effect on nitrogen, phosphorus andorganic matters in sewage.
Description
technical field [0001] The invention belongs to the technical field of water treatment of environmental engineering, and in particular relates to a compound distributed rural sewage treatment system. Background technique [0002] Since the beginning of the new century, with the expansion of the rural economy and the improvement of farmers' living standards year by year, the discharge of rural domestic sewage has continued to increase. This is not only related to the production and life of farmers, but also to the fairness and justice of the entire society. . Therefore, it is imminent to solve the problem of rural domestic sewage. [0003] Rural domestic sewage generally has the characteristics of scattered discharge and large changes in water quality and quantity, and rural sewage collection and treatment facilities are not perfect, which is likely to cause water environmental pollution and affect the safety of drinking water for villagers. Coupled with the constraints of ...
