The Process Design Of Sewage Treatment Plant In A Chemical Industry Park

This paper focuses on the process design of municipal sewage plants in a chemical industrial park.This process design includes of grill, blowers, aerators and improved A2/O technology.In this process design, they use three different technologies (Anaerobic technologies, anoxic technologies and aerobic technologies) to removal biological nitrogen, biological phosphorus and BOD,then keep the process running stable.The sewage treatment standard is according to level3water quality standard which defined in’integrated wastewater discharge standard’, we expect the scale of sewage treatment will be30,000m3/d. Based on the principle of improving the scientific management level and increasing the economic benefit, we must know much about the actual production requirements, the condition of technology, the condition of economy and equipment in order to improve the city sewage treatment capacity.
