1、中文摘要i養(yǎng)豬場(chǎng)污水 養(yǎng)豬場(chǎng)污水 UASB+SBR 工藝處理工程設(shè)計(jì) 工藝處理工程設(shè)計(jì)摘 要養(yǎng)殖業(yè)污水中富含大量營(yíng)養(yǎng)物質(zhì)，若不經(jīng)處理直接外排入水體，往往會(huì)造成水體富營(yíng)養(yǎng)化。養(yǎng)豬廢水的特點(diǎn)是排放集中、水力沖擊負(fù)荷強(qiáng)、有機(jī)質(zhì)濃度高、水解酸化快、沉淀性能好。本設(shè)計(jì)采用 UASB+SBR 處理工藝，該工藝優(yōu)點(diǎn)在于藝對(duì)有機(jī)物、懸浮物、氮和總磷均有很好的去除效果。廢水首先進(jìn)入調(diào)節(jié)池,去除大部分懸浮物和少量有機(jī)物，出水流入集水井，通過(guò)泵輸送到 UA

2、SB 反應(yīng)器，大部分有機(jī)物被降解，并產(chǎn)生沼氣。UASB 反應(yīng)器出水進(jìn)入 SBR 反應(yīng)器進(jìn)行后續(xù)處理，部分有機(jī)物和大部分 NH3-N 被降解。由于 SBR 反應(yīng)器出水 SS、COD還較高，影響出水水質(zhì)，因此通過(guò)氧化塘作進(jìn)一步處理，以滿足達(dá)標(biāo)排放要求。廢水經(jīng)處理后達(dá)到《畜禽養(yǎng)殖業(yè)污染物排放標(biāo)準(zhǔn)》（GB18596-2001）排放標(biāo)準(zhǔn)，本設(shè)計(jì)采用的工藝可達(dá)到預(yù)期的處理效果。關(guān)鍵詞： 關(guān)鍵詞：養(yǎng)豬場(chǎng)廢水；有機(jī)廢水；UASB；SBR；氧化塘目 錄
