【摘要】：排水泵站是城市給排水工程中重要的組成部分，其設(shè)計(jì)和運(yùn)行直接影響整個(gè)社會(huì)的穩(wěn)定與發(fā)展。但目前泵站設(shè)計(jì)運(yùn)行中仍存在著一些問題，本文以西青區(qū)辛口鎮(zhèn)津靜復(fù)線雨污合建泵站建設(shè)為例，充分結(jié)合工程實(shí)際對(duì)泵站建設(shè)的可行性進(jìn)行了較為詳盡的研究。 本次可行性研究首先對(duì)國(guó)內(nèi)外排水泵站的現(xiàn)狀和發(fā)展進(jìn)行了分析總結(jié)，針對(duì)我國(guó)城市排水系統(tǒng)的特點(diǎn)，指出目前國(guó)內(nèi)市政排水泵站設(shè)計(jì)中存在的問題，為今后排水泵站發(fā)展改進(jìn)指明了方向。 其次，對(duì)本項(xiàng)目的工程背景、西青區(qū)及辛口鎮(zhèn)區(qū)域概況、區(qū)域自然條件以及排水現(xiàn)狀等資料進(jìn)行了歸納分析，指出本項(xiàng)工程實(shí)施的必要性。結(jié)合西青區(qū)及辛口鎮(zhèn)當(dāng)?shù)氐淖匀粭l件以及排水現(xiàn)狀，確定泵站采用雨、污分流制排水體制。在確定排水設(shè)計(jì)標(biāo)準(zhǔn)和參數(shù)后，計(jì)算確定雨、污水的泵站規(guī)模。雨水泵站服務(wù)面積約345ha，流量Q=12m3/s；污水泵站服務(wù)面積約2250ha，流量Q=2.2m3/s。根據(jù)規(guī)劃，確定本泵站為雨污水永久性泵站，總占地面積為4600m2。 再次，在確定泵站規(guī)模的基礎(chǔ)上，對(duì)泵站工藝流程進(jìn)行設(shè)計(jì)，計(jì)算確定各構(gòu)筑物的工藝參數(shù)，并對(duì)主要的設(shè)備進(jìn)行比選、定型，其中，格柵設(shè)計(jì)：雨水泵站采用移動(dòng)式格柵3臺(tái)，單個(gè)流量為4m3/s，渠道寬度2.5m，格柵間隙b=50mm；污水泵站采用固液分離機(jī)3臺(tái)，單個(gè)流量約為0.73m3/s，渠道寬度1.5m，格柵間隙b=20mm。泵房設(shè)計(jì)：雨水泵房采用半地下式，，水量Q=12m3/s，選用900QZB-50型潛水軸流泵6臺(tái)，單臺(tái)流量2056L/S，揚(yáng)程8.1m；污水泵房針對(duì)泵站的特殊地理位置（鎮(zhèn)政府旁），提出了全地下式污水泵房配合自控輸送柵渣裝置和除臭裝置的設(shè)計(jì)方案，既保護(hù)了周圍環(huán)境，又節(jié)省了人工勞動(dòng)力。污水泵房水量Q=2.2m3/s，水泵型號(hào)為400WQ1600-10-756臺(tái)，5用2備，流量1600m3/h，揚(yáng)程8.5m。此外，對(duì)建筑、結(jié)構(gòu)、電氣和自控進(jìn)行了設(shè)計(jì)分析。 最后，對(duì)泵站內(nèi)的環(huán)境保護(hù)、勞動(dòng)安全衛(wèi)生、安全防火和節(jié)能等方面進(jìn)行分析，提出了具體的可行性要求。
[Abstract]:Drainage pump station is an important part of urban water supply and drainage project. Its design and operation directly affect the stability and development of the whole society. However, there are still some problems in the design and operation of the pumping station. This paper takes the construction of the pumping station in Xinkou Town, Xiqing District, as an example. The feasibility of pumping station construction is studied in detail. Firstly, the present situation and development of domestic and foreign drainage pump stations are analyzed and summarized, aiming at the characteristics of urban drainage system in China. This paper points out the problems existing in the design of domestic municipal drainage pump station at present, and points out the direction for the future development and improvement of the drainage pump station. Secondly, the engineering background of the project and the general situation of Xiqing district and Xinkou town area are given. The regional natural conditions and drainage status are summarized and analyzed, and the necessity of this project is pointed out. Combined with the local natural conditions and drainage status in Xiqing District and Xinkou Town, the drainage system of rain and sewage distribution system was determined. After determining the design criteria and parameters of drainage, the size of pumping station for determining rain and sewage is calculated. The service area of Rain Water pumping station is about 345ha, the flow rate is 12m3 / s, and the service area of sewage pumping station is about 2250ha. the flow rate is 2.2 m3 / s. According to the plan, the pump station is determined to be a permanent pumping station with a total area of 4600m2. Thirdly, on the basis of determining the scale of the pumping station, the technological process of the pump station is designed, and the technological parameters of each structure are calculated and determined. The main equipments are compared and selected, and the design of grid is as follows: Rain Water pump station adopts 3 mobile grille, single flow rate is 4m3 / s, channel width is 2.5m, gap between grille is 50mm, sewage pumping station adopts three solid-liquid separator, The single flow rate is about 0.73 m3 / s, the channel width is 1.5 m, and the grid gap is 20 mm. Pump room design: rain water pump room is semi-underground, water quantity is 12m3 / s, and 900QZB-50 submersible axial flow pump is used. The sewage pump room is aimed at the special geographical position of the pump station (next to the township government, the design scheme of the all-underground sewage pump room combined with the self-controlled grid slag device and the deodorizing device is put forward, which not only protects the surrounding environment, but also has the following advantages: 1) the flow rate of the pump station is 2056L / S, and the head is 8.1 m. The labor force is also saved. The sewage pump room water quantity is 2.2 m3 / s, the pump model is 400WQ 1600-10-756 sets with 2 sets, the flow rate is 1600 m3 / h, the head is 8.5 m. In addition, the design and analysis of building, structure, electric and automatic control are carried out. Finally, the feasibility requirements of environmental protection, labor safety and health, fire prevention and energy saving in pump station are put forward.
