【實(shí)用技術(shù)】內(nèi)蒙古水產(chǎn)養(yǎng)殖十項(xiàng)主推技術(shù)模式（九）集中連片池塘養(yǎng)殖尾水處理技術(shù)模式

導(dǎo)讀：近幾年，內(nèi)蒙古對呼和浩特市、巴彥淖爾市、鄂爾多斯市、通遼市、烏海市、阿拉善盟等地1000畝以上的集中連片池塘開展進(jìn)行了標(biāo)準(zhǔn)化改造和尾水治理。

　　【農(nóng)機(jī)網(wǎng) 科技創(chuàng)新】 技術(shù)概述：對養(yǎng)殖尾水進(jìn)行多級處理后再循環(huán)利用或達(dá)標(biāo)排放。尾水設(shè)施總面積占養(yǎng)殖總面積較大的應(yīng)建立“三池兩壩”，即沉淀池、曝氣池、生態(tài)凈化池以及夾在這三個池塘中間的兩個過濾壩。 養(yǎng)殖池塘排放的尾水通過管網(wǎng)系統(tǒng)排入收集池，再流入一級凈化區(qū)(沉淀池)，經(jīng)自然沉淀后的尾水經(jīng)過溢流壩自流到二級凈化區(qū)(曝氣池)，曝氣增氧后的尾水最后經(jīng)過潛流壩自流入三級凈化區(qū)(生態(tài)池)，實(shí)現(xiàn)循環(huán)利用或達(dá)標(biāo)排放。
 
　　典型案例：近幾年，我區(qū)對呼和浩特市、巴彥淖爾市、鄂爾多斯市、通遼市、烏海市、阿拉善盟等地1000畝以上的集中連片池塘開展進(jìn)行了標(biāo)準(zhǔn)化改造和尾水治理，通過建設(shè)“生態(tài)渠”+“人工濕地”以及“三池兩壩”處理模式，使養(yǎng)殖尾水中的有害固體物、懸浮物、可溶性物質(zhì)從水體中排出或轉(zhuǎn)化為無害物質(zhì)，實(shí)現(xiàn)養(yǎng)殖尾水資源化綜合利用或達(dá)標(biāo)排放，促進(jìn)水產(chǎn)養(yǎng)殖業(yè)綠色發(fā)展。
