Study on Energy Saving and Resources Comprehensive Utilization in a Large Dyeing Industrial Park

Abstract

This paper studied the wastewater treatment in GAO Yang Dyeing and Textile Industrial Park, with the dealing capacity of 19x104 ton/d, on its wastewater discharge, water reuse, energy saving and resources utilization. Through the process optimization consisted of the enhanced chemical conditioning, diagonal up-flow anaerobic reactor, intelligent closed-loop oxygen supply system, double membrane water recycle process and sludge drying- burning circulation, the effluent water all reached the "Emission Standards for Municipal Wastewater Treatment Plant", (GB18918-2002) Alevel, the whole system operated steadily for 2 years and achieved tremendous economic and environmental benefits.
