The Courtyard Wastewater Treatment Equipment is designed for rural domestic wastewater discharge, which is characterized by scattered distribution and low discharge volume, making it unsuitable for constructing centralized wastewater pipeline treatment systems. It adheres to the environmental protection concept of "source control and recycling," drawing upon successful experiences from both domestic and international decentralized wastewater treatment. It is a newly developed micro-power courtyard wastewater treatment equipment.

The courtyard-style wastewater treatment equipment is powered by an electrical grid system. The equipment casing is made of pressed composite materials, which are resistant to aging and corrosion. It can meet the needs of various scales of decentralized domestic wastewater treatment, including large-scale farmers, small "agritainment" facilities, and small town enterprises. The main treatment process employs the principle of microbial cyclic degradation, gradually decomposing the wastewater and removing nitrogen and phosphorus as it flows through different treatment units, achieving water purification. The treated effluent meets the standards for green space irrigation and can be used for irrigation purposes.
