【摘要】：在系統(tǒng)分析現(xiàn)有污水處理廠存在進(jìn)水水質(zhì)中SS含量較高、出水總氮不能達(dá)標(biāo)排放及剩余污泥含水量較高等問(wèn)題的基礎(chǔ)上,通過(guò)現(xiàn)場(chǎng)調(diào)研與實(shí)驗(yàn)、實(shí)測(cè)相結(jié)合的方式,指出了進(jìn)水SS含量高的原因,提出采用增加平流沉砂池來(lái)化預(yù)處理,降低出水SS含量,減少其對(duì)生物作用的負(fù)面影響；通過(guò)考察生物硝化與反硝化作用的效果,揭示出水總氮超標(biāo)的原因,提出減小污泥負(fù)荷、延長(zhǎng)水力停留時(shí)間和增補(bǔ)優(yōu)勢(shì)菌種PCN等措施,有效提高生物硝化與反硝化效率,出水總氮實(shí)現(xiàn)達(dá)標(biāo)排放；運(yùn)行相關(guān)軟件包對(duì)進(jìn)、出水水質(zhì)參數(shù)的相關(guān)性進(jìn)行了分析,揭示了進(jìn)水BOD_5/TN對(duì)出水TN兩變量中度負(fù)相關(guān),進(jìn)水BOD_5/TP對(duì)出水TP兩變量低度負(fù)相關(guān),進(jìn)水BOD_5/COD對(duì)出水TP相關(guān)程度弱,進(jìn)水SS/BOD_5對(duì)出水TN基本不相關(guān)等進(jìn)水水質(zhì)與出水水質(zhì)間的關(guān)聯(lián)性,為污水處理廠的提標(biāo)改造提供借鑒。對(duì)剩余污泥含水量高的原因進(jìn)行了分析,通過(guò)改造脫水設(shè)備降低污泥含水率。通過(guò)工藝改造后的系統(tǒng)運(yùn)行分析發(fā)現(xiàn),工藝改造后的各項(xiàng)水質(zhì)指標(biāo)均有較大幅度的提升,COD、TN、NH3-N、TP及SS的去除率分別達(dá)到84%,30%,94%,76%和95%以上,出水指標(biāo)均達(dá)到《城鎮(zhèn)污水處理廠污染物排放標(biāo)準(zhǔn)》GB18918-2002一級(jí)A排放標(biāo)準(zhǔn)；污泥含水率在60%以下；且改造后的工藝具有運(yùn)行穩(wěn)定,抗沖擊負(fù)荷的能力。
[Abstract]:On the basis of systematical analysis of the problems of high SS content in influent water quality, high total nitrogen content in effluent and high water content of excess sludge in existing wastewater treatment plants, the method of combining field investigation and experiment with actual measurement is adopted. The reasons for the high SS content in influent were pointed out, and the effect of biological nitrification and denitrification was investigated by adding advection sand tank to pretreatment, reducing SS content in effluent and reducing its negative effect on biological action. In order to improve the efficiency of biological nitrification and denitrification, the effluent total nitrogen can be discharged up to the standard, and the relevant software package should be run in order to improve the efficiency of biological nitrification and denitrification, and put forward the measures of reducing the sludge load, prolonging the hydraulic retention time and supplementing the dominant strain PCN. The correlation of effluent water quality parameters is analyzed. It is revealed that influent BOD5 / TN has moderate negative correlation with effluent TN, influent BOD5 / TP has low negative correlation with effluent TP, influent BOD5 / COD has weak correlation with effluent TP. The relationship between influent water quality and effluent quality is basically irrelevant to effluent TN by SS- / BOD5, which can be used as a reference for upgrading and upgrading of wastewater treatment plant. The reasons for the high water content of excess sludge were analyzed, and the sludge moisture content was reduced by revamping dewatering equipment. Through the analysis of the system operation after the process transformation, it is found that the removal rates of COD, TNN, NH _ 3-NU _ (TP) and SS are over 84% and 95%, respectively. The effluent indexes are all up to the first class A discharge standard of GB18918-2002, the sludge moisture content is below 60%, and the modified process has the ability of running stably and resisting shock load.
