蒸发池是污水处理、石油化工等领域的重要设施之一

蒸(zheng)发池是污(wu)水处理、石(shi)油化(hua)工(gong)(gong)等(deng)领域的重(zhong)要设施(shi)之一，HDPE土工(gong)(gong)膜(mo)，即高(gao)密度(du)聚乙烯膜(mo)，作为(wei)蒸(zheng)发池的防渗(shen)材(cai)料，具有强度(du)高(gao)、柔韧性(xing)好(hao)，以及优异的耐(nai)候性(xing)、耐(nai)腐(fu)蚀性(xing)、抗老(lao)化(hua)性(xing)能。为(wei)了(le)确(que)保(bao)蒸(zheng)发池HDPE土工(gong)(gong)膜(mo)的施(shi)工(gong)(gong)质量和使用(yong)寿命，需要采(cai)取合理的施(shi)工(gong)(gong)工(gong)(gong)艺和严(yan)格(ge)的质量控制措施(shi)。

项目蒸(zheng)发池(chi)(chi)(chi)(chi)分为(wei)盐(yan)水(shui)蒸(zheng)发池(chi)(chi)(chi)(chi)和生物(wu)脱硫蒸(zheng)发池(chi)(chi)(chi)(chi)，本文以面(mian)积(ji)更大的盐(yan)水(shui)蒸(zheng)发池(chi)(chi)(chi)(chi)为(wei)例(li)来说明。盐(yan)水(shui)蒸(zheng)发池(chi)(chi)(chi)(chi)尺(chi)寸为(wei)235/m×180/m×4.75/m，由(you)于池(chi)(chi)(chi)(chi)底设计有坡(po)度(du)(du)(du)，池(chi)(chi)(chi)(chi)底最深处5.1/m，中间有堤坝把(ba)池(chi)(chi)(chi)(chi)子分为(wei)A，B两个对称池(chi)(chi)(chi)(chi)子，独立进(jin)水(shui)，四周边(bian)坡(po)长(zhang)度(du)(du)(du)8.6/m（坡(po)度(du)(du)(du)1∶1.5），池(chi)(chi)(chi)(chi)底有20/m×20/m混凝土平台(tai)，从(cong)地面(mian)有4m宽混凝土坡(po)道与池(chi)(chi)(chi)(chi)底平台(tai)相连（坡(po)度(du)(du)(du)1∶10）。混凝土池(chi)(chi)(chi)(chi)底、坡(po)道以及混泥土进(jin)水(shui)口都有HDPE预埋件(jian)，以便之后与土工(gong)膜(mo)焊接。本项目采用的是厚度(du)(du)(du)1.5/mm，背面(mian)带微(wei)凸起的土工(gong)膜(mo)。
