Renovation and Expansion Design of Domestic Sewage Stations in Zhaolou Coal Mine
In order to solve the problem that the domestic sewage treatment station in Zhaolou Coal Mine does not meet the standard,the existing sewage treatment station was rebuilt and expanded by means of field investigation,process comparison and scheme comparison.After process comparison and scheme comparison,the reconstruction project adopts the process of"biological aerated filter+sand filtration"to build a 3500 m domestic sewage treat-ment station.After transformation,the effluent quality can meet the requirements of the three kinds of surface wa-ter quality,and the design and production cost can reach 1.19 yuan/m3.This paper mainly introduces the determi-nation method of sewage treatment process and transformation scheme,and gives the process flow,design parame-ters and effect analysis,in order to provide a reference for similar projects.
