Research on Rural Wastewater Treatment Technology in Northwest China Based on Anaerobic Biofilm Coupled with Anaerobic Baffle Plate Reactor (ABR) Technology

The northwest of China has a shortage water resources, and classic sewage treatment techniques have high cost produce waste nitrogen phosphorus. In order to achieve inexpensive discharge standards, an anaerobic biofilm coupled with ABR technology was adopted as for normal rural wastewater in the arid semi-arid vicinity Northwest investigate its operational impact on China’s domestic wastewater. results illustrated that best pollutant elimination effect reached under conditions set temperature 35 °C, hydraulic retention time 3 d application suspended ball filler hanging carrier. Therefore, aggregated process can boost purification capacity offer reference solving difficulty non-agricultural irrigation areas.
