Ten million tons of sewage treatment plant design
With the development of the city,together with the porgress of the industry,invironment,espedially the water,is being under suriously polluted.So this design is main to do a research on every kind of urban sewage processing craft,compared with these crafts by technology and economy,and try to find a suitdble sewage process for the Hulan town in Harbin, and do a design of sewage treatment plan for the city. The total design water volume is 100000m3/d,the main body craft is A2/O craft.The A2/O craft has a simple flow, a stable movement and a nice sludge settling property ,as long as a good denitrogenation eliminates the phosphorus effect,it’s really suitable for big scale Sewage treatment plant.This design is mostly to do a calculation for various constructions of the waterway and sludgeway,and select equipments,then integrate blueprints. Keywords:A2/O craft;Pump room; Sewage treatment;Sludge treatment
