摘 要

随着城市的发展,以及工业的进步,环境尤其是水体也正受着严重的污染。所以本设计主要是研究城市污水的各种处理工艺,通过对各工艺技术经济的比较,为哈尔滨呼兰镇选用适合的污水处理工艺,并为该城市设计污水处理厂。总设计水量为100000m3/d,拟采用的主体工艺为A2O法。A2/O工艺流程较简单,运行稳定,污泥沉降性能好,并且有良好的脱氮除磷效果,非常适合较大规模的污水处理厂。本设计主要是对水路、泥路的各构筑物的计算及设备选型,并进行图纸绘制。

Ten million tons of sewage treatment plant design

Abstract

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.
