甘洛縣海棠產(chǎn)業(yè)園區(qū)（正西片區(qū)）生產(chǎn)用水處理后排水2海棠產(chǎn)業(yè)園區(qū)排污管道工程DN200～DN300（ 500 m3/d）甘洛縣海棠產(chǎn)業(yè)園區(qū)（正西片區(qū)）污水處理廠所有收集主干管網(wǎng)建設(shè)期限：1521 個(gè)月（前期工作 2~4 個(gè)月，設(shè)計(jì) 2~3 月，施工10~12 月，驗(yàn)收 12 月）。我公司受甘洛縣工業(yè)集中區(qū)管理委員會(huì)的委托，進(jìn)行甘洛縣海棠產(chǎn)業(yè)園區(qū)污水管道收集及海棠產(chǎn)業(yè)園區(qū)污水處理廠工程可行性研究報(bào)告的編制工作。四川涼山彝族自治州甘洛縣海棠產(chǎn)業(yè)園區(qū)正在建設(shè)，一旦建成工業(yè)廢水如果直接排放將會(huì)給人們生產(chǎn)生活帶來嚴(yán)重影響，如果工業(yè)污水未經(jīng)任何處理或只經(jīng)過簡(jiǎn)單的化糞池預(yù)處理便排入附近河流、溝渠會(huì)造成嚴(yán)重水環(huán)境污染；污水中含有的大量重金屬、細(xì)菌、病毒會(huì)對(duì)周邊及下游人畜的飲用水源安全及健康造成嚴(yán)重潛在危害。甘洛縣海棠產(chǎn)業(yè)園區(qū)污水處理廠工程可行性研究報(bào)告四川西南交大土木工程設(shè)計(jì)有限公司2022
