1、摘要摘要我國是水資源短缺的國家。由于存在著這些問題，使我們對水資源的利用應更加趨于理性，更加科學。在科學技術(shù)突飛猛進的21世紀，我們要合理利用科學技術(shù)對原水進行水質(zhì)處理，經(jīng)過合理的技術(shù)經(jīng)濟比較，以滿足人們對水資源不斷增長的迫切需要。本設計采用的主要構(gòu)筑物有：取水構(gòu)筑物及取水泵站，穩(wěn)壓井，投藥間，機械混合器，折板絮凝池，斜板沉淀池，均質(zhì)濾料濾池，清水池，加氯設備，吸水井，送水泵站，還有輸水管線。穩(wěn)壓井起到穩(wěn)定水壓的作用。絮凝池采用折板絮凝池，該池絮凝時間短，絮凝效果好。沉淀池才用斜板沉淀池，該池可以大大降低雷諾數(shù)，從而減小水的紊動，促進沉淀，加設斜板，使顆粒

2、沉淀距離縮短，減小了沉淀時間。濾池采用均質(zhì)濾料濾池，該池慮速較高，過濾周期長，出水效果好，單池面積較大時，有利布水均勻，因此更適用于大中型水廠，沖洗采用空氣，水反沖和表面掃洗，提高了沖洗效果并節(jié)約沖洗用水。送水泵站選用兩種型號的水泵，最大限度的使供水曲線與擁護用水曲線相吻合。管網(wǎng)中為保證不間斷供水采用環(huán)狀管網(wǎng)布置，定線原則是平行設置幾條干管，按規(guī)劃道路定線，且指向大用戶靠近大用戶。在環(huán)狀管網(wǎng)中設置消火栓，按照國家規(guī)范每隔120米設置一消火栓，在整個城區(qū)地勢高出設排期閥，在地勢低處設泄水閥。關(guān)鍵字：水資源；絮凝沉淀池；均質(zhì)濾料濾池；取水構(gòu)筑物及送水泵站；管網(wǎng)
