摘要:
As a new sewage treatment technology, biological activated carbon technology has the advantages of simple operation, economic reliability, and it has a good application prospect in wastewater treatment.In this experiment, taking chemical wastewater treated in sewage treatment plant as the research object, using biological activated carbon process to conduct advanced treatment, a new way of chemical wastewater treatment is obtained.The results show that after the advanced treatment of chemical wastewater by biological activated carbon technology, the COD removal rate can reach about 40%,and ammonia nitrogen removal rate is about 60%.And the effluent can reach environmental quality standard of surface water.%作為一種新的污水處理工藝,生物活性炭技術(shù)具有操作簡(jiǎn)單、經(jīng)濟(jì)可靠等優(yōu)點(diǎn),在污水深度處理中有著良好的應(yīng)用前景.以某污水處理廠處理過(guò)的化工廢水為研究對(duì)象,采用生物活性炭工藝對(duì)其進(jìn)行深度處理,以獲得化工類廢水深度處理的新途徑.結(jié)果表明,化工類廢水經(jīng)過(guò)生物活性炭技術(shù)深度處理后,COD的去除率可達(dá)40%左右,氨氮的去除率可達(dá)60%左右,工藝出水可達(dá)到地表水環(huán)境質(zhì)量標(biāo)準(zhǔn).
摘要:
The anaerobic degradation model for municipal solid waste ( MSW) is developed to study the influence of temperature on the biochemical degradation process in MSW. The existing first-order dynamic equation of biochemical degradation is improved to take the temperature into consideration by introducing a temperature dependent coefficient for both hydrolysis and methanogenesis process. With the numerical simulation program OGS, the impacts of temperature on the degradation proces-ses of cellulose, total sugar, protein and fat are analyzed, and also the hydrolysis and methanogene-sis processes at different temperature are investigated. The thermo-hydro-mechanical-chemical-bio-logical ( THMCB ) coupled model is calibrated by a pilot-scale experiment of MSW to reveal the effect of temperature in multi-field coupling. The results show that in the temperature range of 10 to 45 °C, the biological degradation process can be significantly affected by temperature.%通過(guò)建立厭氧降解模型研究了溫度對(duì)城市固廢中生化降解過(guò)程的影響,對(duì)已有的生化降解反應(yīng)速率一級(jí)動(dòng)力方程進(jìn)行了修正,通過(guò)加入溫度影響系數(shù)考慮溫度的影響?;贠GS軟件,通過(guò)數(shù)值計(jì)算分析了溫度對(duì)城市固廢中纖維素、總糖、蛋白質(zhì)和脂肪組分的降解過(guò)程的影響,并研究了不同溫度下的水解與甲烷化過(guò)程。將大型模型槽試驗(yàn)數(shù)據(jù)與數(shù)值計(jì)算結(jié)果進(jìn)行對(duì)比,揭示了溫度在多場(chǎng)耦合作用中的影響。結(jié)果表明,在10~45°C溫度范圍內(nèi),溫度會(huì)顯著影響水解與甲烷化進(jìn)程的反應(yīng)速率。
摘要:
The activated sludge was acclimated into high salt tolerant sludge through increasing the concentration of sodium chloride and ammonia nitrogen periodically. Ammonia nitrogen was degraded from 100 mg/L to below 15 mg/L by the high salt tolerant sludge in 24 h, when the sodium chloride content of influent was 30 mg/L. Bacteria liquid containing salt tolerant nitrifying bacteria were cultured by the salt tolerant nitrifying bacteria enriched and screened from high salt tolerant sludge. The quantity of bacteria in the bacteria liquid was largest when the growth time was 24 h. The ammonia nitrogen biodegradation process was effectively enhanced after the 24 h growth bacteria liquid was put into wastewater with high salinity in a certain proportion. The removal rate of ammonia nitrogen was proportionate to the dosage of the salt tolerant nitrifying bacteria liquid.%通過(guò)階段性提高氯化鈉和氨氮濃度,將生活污水二沉池活性污泥馴化成為耐鹽硝化污泥。在進(jìn)水 NaCl含量為30 mg/L的條件下,經(jīng)過(guò)24 h處理后,耐鹽硝化污泥可以將氨氮從100 mg/L降解到15 mg/L以下。對(duì)該污泥進(jìn)行富集篩選出耐鹽硝化菌。利用分離出的菌種培養(yǎng)出含有耐鹽硝化菌的菌液。菌液生長(zhǎng)時(shí)間24 h時(shí),細(xì)菌數(shù)量最大。將生長(zhǎng)24 h的耐鹽硝化菌液以一定比例投入高含鹽的廢水中,可以有效強(qiáng)化氨氮的生化降解過(guò)程,并且氨氮的去除率與耐鹽硝化菌液的投加量成正比關(guān)系。
