摘要：The down industry is one of the special agricultural industrial clusters in West Anhui province, China. There are large drainage and large pollution load in the washing down industry. By analysing the characteristics of wastewater from down washing industry, it is proposed that the enterprises of down industry should separate heavily polluted wastewater from slightly polluted and reuse the wastewater directly or after regeneration treatment. According to the gathering situation of down feather industrial enterprises in West Anhui province, it is proposed to build down feather industrial park and down specialized sewage treatment plant in the industrial gathering area, so as to solve the pollution problem of enterprises through centralized treatment and make industry bigger and stronger.
