The courtyard-style wastewater treatment equipment is designed for rural domestic wastewater discharge, which is scattered and low in volume, not suitable for constructing centralized pipeline treatment systems. It adheres to the environmental protection concept of "source control and recycling," fully drawing on successful experiences from both domestic and international decentralized wastewater treatment. It is a newly developed micro-power courtyard-style wastewater treatment equipment.

The courtyard-style wastewater treatment equipment is powered by an electrical grid system, featuring a shell made of molded composite materials, which is resistant to aging and corrosion. It can meet the decentralized domestic wastewater treatment needs of various scales, including large-scale farmers, small "country resorts," and small town enterprises. The treatment process primarily employs the principle of microbial cyclic degradation, gradually degrading and removing nitrogen and phosphorus as the wastewater flows through different treatment units, achieving water purification. The treated effluent meets the irrigation standards for green spaces and is used for irrigation purposes.
