摘 要

 隨著城市的發(fā)展，以及工業(yè)的進(jìn)步，環(huán)境尤其是水體也正受著嚴(yán)重的污染。所以本設(shè)計(jì)主要是研究城市污水的各種處理工藝，通過對各工藝技術(shù)經(jīng)濟(jì)的比較，為哈爾濱呼蘭鎮(zhèn)選用適合的污水處理工藝，并為該城市設(shè)計(jì)污水處理廠。總設(shè)計(jì)水量為100000m3/d,擬采用的主體工藝為A2O法。A2/O工藝流程較簡單，運(yùn)行穩(wěn)定，污泥沉降性能好，并且有良好的脫氮除磷效果，非常適合較大規(guī)模的污水處理廠。本設(shè)計(jì)主要是對水路、泥路的各構(gòu)筑物的計(jì)算及設(shè)備選型，并進(jìn)行圖紙繪制。

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.
