| 摘 要： | 采用铁炭微电解技术为核心工艺的混凝-铁炭微电解-强化电解组合工艺对大蒜切片废水进行处理,主要研究了铁炭微电解的运行参数,包括曝气与否、废水pH值、反应时间、铁炭质量比、铁水质量比对COD去除效果的影响。结果表明:经过组合工艺处理后,废水刺鼻的气味完全消除,浊度去除率达100%,ρ(COD)值由13050mg/L降至878mg/L,去除率达93.3%,BOD5/COD(B/C)值由0.10提高到0.46,废水的可生化性显著提高。

| Abstract: | A special treatment process of integrated coagulation-iron-carbon micro-electrolysis-reinforced electrolysis process was employed to treat garlic wastewater with iron-carbon micro-electrolysis as the core technology.Effect of micro-electrolysis operation parameters on the COD removal rate was studied,including aeration,pH of the water,reaction time,iron-carbon mass ratio and iron-water mass ratio.Experimental results showed that after being pretreated with integrated process,the pungent aromatic smell of garlic wastewater was totally eliminated,the removal rate of turbidity was up to 100%,the COD value of garlic wastewater was reduced from 13050 mg/L to 878 mg/L with the total COD removal rate of 93.3%.And the ratio of BOD5/COD(B/C) was improved from 0.10 to 0.46.The biodegradability of wastewater was significantly improved. |
