Abstract

The invention provides rural domestic wastewater treatment equipment which comprises a shell (12) and an inner supporting wall (11). The inner supporting wall (11) is divided into a biological filter layer (1), a composite biological reaction layer (4) and one to three water collecting layers (5) from top to bottom through supporting plates (2). A ventilating layer (3) is arranged between every two adjacent layers. Small water leakage holes are distributed in the supporting plates (2). The biological filter layer (1) is filled with a biological filter material. A water distributor (6) is arranged above the biological filter layer (1). The water collecting layers (5) are provided with water outlet pipes (10). A biochemical system is enhanced through the composite biological reaction layer, the bearing capacity of pollution loads is improved, microbial flora cultivation environments under different anaerobic, aerobic and aerobiotic resistant conditions are provided, and the long-term maintenance-free purpose can be achieved. The wastewater treatment and operation cost is low, the treatment cost is good, and the effluent quality can reach the national urban wastewater discharge standard.

Description

technical field [0001] The invention relates to water treatment equipment, in particular to rural sewage treatment equipment, in particular to a rural domestic sewage treatment equipment with low operating cost and zero power consumption. Background technique [0002] The lack of water resources and water pollution are important obstacles restricting the healthy and sustainable development of my country's economy, and the hazards of water pollution and their control have attracted much attention. Municipal sewage treatment plants collect sewage and centralize treatment. In rural areas, the infrastructure lags behind and the management level is low, and the amount of sewage treatment is small, the area is scattered, the management is difficult, and the operating cost is high. As a result, most of the domestic sewage and agricultural sewage in rural areas are directly discharged without treatment, leading to the deterioration of the local environment. The direct flow of sewag...
