UASB-SBR Biochemical System Treating Pharmaceutical Wastewater Emission Reduction Research

Anaerobic aerobic system^has been in the treatment of industrial and municipal wastewater using anaerobic system for a longer period of time, high volume load and the aerobic system of low load and high removal rate of CODcr is the set of stable operation of the system’s cornerstone. UASB-SBR biochemical system is very representative of the anaerobic aerobic system, its operation is relatively simple, operation cost is reasonable, for the high concentration pharmacy wastewater treatment has formed a more mature process control parameters [2]. Based on the analysis of the sewage the normal operation of the system under the premise, in response to the local energy conservation and emission reduction, cleaner production ideas and policies, factories in the absence of production under the premise of control of the production of drainage volume, by raising the influent concentration, lower into the water, the sewage system in the700m/D, CODcr7500mg/L, overexpression of300m/D, CODcr16500mg/L stability during operation, which not only reduces the sewage charges, water saving, but also reduce the work intensity of operators. The case of the successful operation of the sewage system, proved the potential of mining work the necessity, proposed the similar factories through reduction, control of wastewater emissions, the sewage system operation cost and other issues will be solved. This paper based on the Hohhot supporting Electric Industrial Park Jin Dawei pharmaceutical anaerobic-aerobic process for treatment of wastewater from production of yellow pigment in the project operation, the factory emissions sewage system operation analysis.
