Abstract
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.
Highlights
Based on the excellent breed resources of the West Anhui white goose and unique geographical environment, the West Anhui region has established a deep processing system for down products, and it is “China export base of fine down products" and "national professional demonstration base of foreign trade transformation and upgrading" [1, 2]
According to the information released on the website of the Lu'an municipal government, in the second half of 2018, the Lu'an municipal environmental authorities imposed administrative penalties on two washing down enterprises for allegedly discharging water pollutants in excess of national standards or operating sewage treatment equipment improperly
It is important to formulate a reasonable water pollutant control route for the washed down industry based on the agglomeration characteristics of the West Anhui down industry and the wastewater discharge characteristics of washed down enterprises
Summary
Based on the excellent breed resources of the West Anhui white goose and unique geographical environment, the West Anhui region has established a deep processing system for down products, and it is “China export base of fine down products" and "national professional demonstration base of foreign trade transformation and upgrading" [1, 2]. It has cultivated the down and feather industry cluster of Guzhen town and the down products cluster of Shucheng county[3], which is one of the largest down export regions in China. It is important to formulate a reasonable water pollutant control route for the washed down industry based on the agglomeration characteristics of the West Anhui down industry and the wastewater discharge characteristics of washed down enterprises
