【摘要】：探討了海泡石與生物質(zhì)炭投加對于厭氧技術(shù)處理養(yǎng)豬廢水效能的影響,并通過三維熒光光譜(EEM)與傅里葉紅外光譜(FTIR)分析了海泡石與生物質(zhì)炭對于厭氧污泥溶解性微生物產(chǎn)物(SMP)及胞外聚合物(EPS)組分的影響.結(jié)果表明,投加海泡石與生物質(zhì)炭后,提高了厭氧反應(yīng)器對COD與氨氮的去除效果,對COD的平均去除率分別提高了10.1%與15.4%,對氨氮的去除率最高分別達(dá)到了50.9%和71.5%.對于厭氧污泥SMP而言,投加海泡石后,其FTIR光譜中2930cm~(-1)、1460cm~(-1)處的吸收峰減弱,表明其對養(yǎng)豬廢水中大分子有機(jī)物的去除效果有一定程度增強(qiáng);而投加生物質(zhì)炭后,其EEM光譜中類富里酸(Ex/Em=340nm/420nm)的吸收峰強(qiáng)度降低,從而提高了厭氧反應(yīng)器出水水質(zhì).對于厭氧污泥EPS而言,通過EEM分析可知,投加生物質(zhì)炭后厭氧污泥中簡單類蛋白(Ex/Em=225nm/340nm)吸收峰、色氨酸類蛋白(Ex/Em=280/340nm)吸收峰強(qiáng)度增大,蛋白含量的提高有利于厭氧污泥的絮凝;同時出現(xiàn)了輔酶F420(Ex/Em=420nm/470nm)的吸收峰,這表明加入生物質(zhì)炭后,厭氧反應(yīng)器內(nèi)產(chǎn)甲烷菌活性更佳,為厭氧反應(yīng)器對養(yǎng)豬廢水的高效處理提供了保障.
[Abstract]:The effect of sepiolite and biomass carbon on the efficiency of anaerobic treatment of pig wastewater was discussed. The effects of sepiolite and biomass carbon on soluble microbial product (SMPP) and extracellular polymer (EPSs) of anaerobic sludge were analyzed by means of three dimensional fluorescence spectroscopy (EEM) and Fourier transform infrared spectroscopy (FTIR). The results showed that the removal efficiency of COD and ammonia nitrogen was improved by adding sepiolite and biomass carbon, the average removal rate of COD was increased by 10.1% and 15.4% respectively, and the highest removal rate of ammonia nitrogen reached 50.9% and 71.5% respectively. For anaerobic sludge SMP, when sepiolite was added, the absorption peak at 2930 cm ~ (-1) and 1460 cm ~ (-1) in FTIR spectra was weakened, which indicated that the removal of macromolecular organic compounds in pig wastewater was enhanced to some extent, and biomass carbon was added. The absorption peak intensity of the absorption peak of the EEM spectra is decreased, which improves the effluent quality of the anaerobic reactor. For anaerobic sludge EPS, EEM analysis showed that the absorption peak of simple protein in anaerobic sludge was 225nm / 340nm ~ (-1), the intensity of absorption peak of tryptophan protein was increased, and the increase of protein content was beneficial to the flocculation of anaerobic sludge. At the same time, the absorption peak of coenzyme F420Nm / Em / 420nm / 470nm) appeared, which indicated that the methanogenic activity of anaerobic reactor was better after adding biomass carbon, which provided a guarantee for the efficient treatment of pig wastewater by anaerobic reactor.
