摘要:遼寧省TZG市排水工程規(guī)劃及污水處理廠的設(shè)計(jì)內(nèi)容為：污水管道的規(guī)劃與設(shè)計(jì)、雨水管道的規(guī)劃與設(shè)計(jì)及污水處理廠的設(shè)計(jì)。
該市面積約為1600多公頃，被鐵路劃分為三個(gè)區(qū)，其中一區(qū)人口密度為310人/公頃，二區(qū)人口密度為320人/公頃，三區(qū)人口密度為360人/公頃，其中甲工廠（位于一區(qū)）的排水量為220 m3/h，乙工廠（位于三區(qū)）的排水量為280 m3/h，丙工廠（位于三區(qū)）的排水量為330 m3/h.在該市的南面有一條自東向西的河流，河水的最高水位為64m,最低水位為60m,常年主導(dǎo)風(fēng)向?yàn)闁|南風(fēng)，城市綜合徑流系數(shù)為0.64，冰凍線為-1.00m.
本工程設(shè)計(jì)采用分流制排水體制。污水處理廠設(shè)在河的下游，城市的西南部，遠(yuǎn)離城區(qū)，占地約23公頃,采用二級(jí)處理,處理水量為131401m³/d，進(jìn)水BOD為227.37 g/m3。
雨水直接排入河流中，為重力流。
平面布置在滿足工藝流程的前提下，利用原有地形設(shè)置，布置大致分為四個(gè)區(qū)：生活區(qū)、污水處理區(qū)、污泥處理區(qū)、預(yù)留地。要求布置緊湊、進(jìn)出水流暢、節(jié)省用地。
關(guān)鍵詞：污水管道;雨水管道;污水處理廠;分流制
Abstract
The design elements of TZG City, Liaoning Province drainage works planning and design of a sewage treatment plant: Sewage pipelines planning and design, stormwater pipelines planning and design and the sewage treatment plant design.
The area of the city is more than one thousand six hundred hectares, it is divided into three areas By the railway, the population density of the first area is 310 persons / ha, the population density of the second area is 320 persons / ha, the population density of the third area is 360 persons / ha.The displacement of A factory（Located in the first area ）is 220 m3 / h, the displacement of B factory（Located in the second area ） is 280 m3 / h, the displacement of C factory（Located in the third area ）is 330 m3 / h. In the south of the city there is a river from east to west, the river's highest level is 64m, the minimum water level is 60m, the perennial leading wind direction is south-east, the city's comprehensive runoff coefficient is 0.64, the frozen line is -1.00m.
The engineering design uses the drainage adopted triage system. Sewage treatment plant located in the lower reaches of the river, the south-west of the city, away from the city, covering about 23 hectares, uses secondary treatment to deal with 131401m ³ / d water, the influent BOD is 227.37 g/m3
Rain water is discharged directly into rivers which is gravity flow.
To meet the technological process the layout use the original terrain settings, arranged roughly divided into four areas: living area, sewage disposal areas, sludge treatment area, Reserve. Require compact layout, and out of the water flow, saving space.
Key words: Sewage pipelines; stormwater pipelines; the sewage treatment plant; Triage system
