摘要
论文以焦化废水为研究对象,考察了生物处理和物化处理联合工艺的处理功效,并对其经济性进行了分析评价,确定了焦化废水的最佳处理工艺,研究结果对焦化废水的处理具有重要的实际应用价值和理论意义。
论文分析比较了传统活性污泥法和膜-生物反应器两种工艺的处理效果,结果表明,膜-生物反应器对COD、NH3-N、TN和TOC的去除率分别为88%,100%,86%和88.3%,高于传统活性污泥法对其的去除。在膜-生物反应器的基础上,考察了采用活性炭吸附和活性炭-微波联合两种深度工艺,并对两种处理工艺的处理效果和成本进行对比。研究结果指出,膜-生物反应器与活性炭-微波联用工艺处理焦化废水,可达到优良的处理效果,在最佳运行参数下,出水COD<80mg/L、TOC<25 mg/L、NH3-N<0.5 mg/L、TN<25mg/L、UV254<0.9cm-1和色度<50倍,达到了国家污水综合排放一级标准。而且,活性炭-微波联用处理工艺,因微波对活性炭的再生作用,其处理成本低于单独活性碳处理成本。
论文同时考察了活性炭-微波联用工艺中活性炭种类、活性炭用量、pH值、微波时间、微波功率、活性炭使用次数对COD、TOC、TN和色度去除效果的影响。当活性炭种类为煤质炭、活性炭用量为60g/L、微波时间为3min、微波功率为464W时,COD、TOC、TN、UV254和色度的去除率分别为:63%、75%、68%、80%和78%。
This paper took coke wastewater as the research object, sueveyed the effects between biological treatment and physicochemical treatment, which economic was analyzed. At last, the best treatment process that treated coke wastewater were determined. The research results had important significance for coke wastewater treatment.
The treatment effects between conventional activated sludge (CAS) and membrane bioreactor (MBR) were compared. The results showed that the removal rate of CODcr, NH3-N, TN, TOC reached 88%,100%,86% and 88.3% respectively by MBR, which was better than CAS. On the base of MBR, the two deep treatment process including activated carbon adsorption and microwave-assisted activated carbon were adopted to treat membrane effluent, at the same time the effect and cost were compared between them. According to the experiment results, treatment of coke-plant wastewater by MBR combined with microwave can receive better effect. In the best operating condition, the CODcr of influent was lower than 80 mg/L, the TOC of influent was lower than 25 mg/L, the NH3-N of influent was lower than 0.5 mg/L, the TN of influent was lower than 25 mg/L, the UV254 of influent was lower than 0.9 cm-1 and the color of influent was lower than 50 TCU. All of indexes could achieve the national I emission standards. Moreover, the cost of microwave-assisted activated carbon process was lower than activated carbon adsorption because that microwave can regenerate activated carbon.
The influential factors such as species and dosage of carbon, pH, the time of microwave, the power of microwave and using times of carbon that impacted on CODcr、TOC、TN and color were investigated in the paper. When the kind of carbon was coal carbon, the dosage of carbon was 60g/L, the time of microwave was 3min and the power of microwave was 464W, removal rate of CODcr, TOC, TN, UV254 and color reached 63%,75%.68%.80% and 78% respectively.
