Research On The Treatment Of Coal-chemical Engineering Wastewater

The characteristics of the coal chemical engineering wastewater is:large water volume, high concentration wastewater and contains a lot of phenols, alkane. aromatic hydrocarbons, heterocyclic, ammonia nitrogen and high concentration of poisonous and harmful material such as melamine material, at the same time with high chromaticity and turbidity, belong to the refractory wastewater. Harbin coal chemical industry co., LTD., China coal dragon of overall wastewater is a typical coal chemical wastewater, the company adopts the external loop combination anaerobic multistage biochemical process waste water reach the national discharge standard.This topic Outlines the following contents:the source of the coal chemical industry wastewater at home and abroad, the water quality characteristics and the research and application status of this kind of wastewater treatment process. Introduces the Harbin coal chemical industry co., LTD., the sewage treatment station of process flow, design parameters and structure; Systematically discusses the sewage treatment station by using the characteristics of various biochemical process. Investigate the best conditions of various processing device for processing point, the maximum processing capacity and system optimization; For each processing unit production research, examines the various processing plant start-up phase and stable phase organic matter degradation ability, resistance to impact load capacity, discusses various microbial population structure in the reactor. Affect all levels of processing device of high efficiency and stable operation of ecological factors were studied, conclusion summary opinion of a certain reference value for practical engineering can provide the reliable theoretical basis for stable operation, technical methods and way to resolve the problem, can make the process better and stable operation for a long time.
