Application of mud membrane coupled integrated buried treatment equipment in rural domestic sewage treatment: a case study of Taizhou, Jiangsu Province
Year: 2024
Type: conference-paper
Abstract: Employing a self-developed mud membrane coupling integrated process along with its underground treatment equipment to manage rural domestic sewage in Taizhou City., Jiangsu Province, this study investigates the treatment effects and performance during continuous stable operation after installation and commissioning of the equipment. Long-term onsite experimental results indicate that the average removal rates of NH4 + -N, COD, TP and TN in sewage are approximately 85.4%, 87.6%, 71.9%, and 73.8%, respectively. The average effluent concentrations are reduced to 4.4, 22, 0.88, and 17.2 mg/L, meeting the primary A standards of Jiangsu Province’s local standard “Village Domestic Sewage Treatment Facility Water Pollutant Discharge Standard” (DB32/T3462-2018). During seven months of stable operation, the sewage system of the equipment runs steadily with a maximum processing capacity of 5 t/d. The removal performance and efficiency of various pollutants remain stable, and the operating cost of the equipment is approximately 0.35 yuan/m3. This equipment demonstrates good performance in rural sewage treatment, strong resistance to shock loads, convenient management, stable operation, and low operating costs, providing valuable reference for other agricultural pollution control projects.
