給水工程初步設計-給水工程畢業(yè)設計完整版

1、摘要隨著我國經(jīng)濟的進步，人民生活水平有了極大的改善，使得人們對生活、飲用水質(zhì)和水量的要求也有所提高。與之相反的是，伴隨著經(jīng)濟發(fā)展所導致的環(huán)境污染也使得自然水質(zhì)降低，這就要求給水排水工程設計人員對城市給水工程有更專業(yè)和更合理的規(guī)劃和設計。本設計為XX省XX鎮(zhèn)給水工程初步設計，設計的主要內(nèi)容包括取水工程、凈水工程、輸水管渠、城市管網(wǎng)、泵站以及其它調(diào)節(jié)構筑物。結合設計規(guī)范以及實際情況，本設計采用如下凈水流程：管式靜態(tài)混合——隔板絮凝池——斜管
