废弃物净化家庭生活污水的资源化利用探究

Research on the resource utilization of the waste water in the domestic sewage treatment

以生活中常见的固体废弃物花生壳、炉渣、钢渣及木炭作为生活污水处理剂,通过对化学需氧量(COD)、色度、臭、氨氮和总磷等水质指标的测定,评价了其对污水的吸附净化效果.结果表明:木炭对污水中COD的去除率显著,为67.42%;以木炭、炉渣和钢渣的混合材料作为吸附材料,可以优势互补,吸附处理后家庭生活污水的COD、色度、臭、氨氮及总磷的综合去除效果更好,对氨氮和总磷的去除效率分别达到84.87%和92.89%.根据上述结果,可以将这些固体废弃物进行资源化利用,为农村家庭生活污水的简易处理和达标排放及其再利用提供可行的途径.

Peanut husk,slag,steel slag and charcoal as common waste in the life,can do simple adsorption material,which should have a certain adsorption and purification in the domestic sewage.Therefore,this experiment uses these solid wastes as the sewage treatment agent,and designs a variety of treatment methods,through the determination of chemical oxygen demand（COD）,color,odor,ammonia nitrogen and total phosphorus and other water quality indicators to evaluate their treatment effect.Results show,the removal rate of COD is the highest,which is 67.42%.But the mixed material with charcoal,slag and steel slag as the adsorption material has the advantages of complementary,the removal rate of COD,chroma,odor,ammonia nitrogen and total phosphorus is higher in the domestic sewage adsorpted,and the removal rates of ammonia nitrogen and total phosphorus are 84.87% and 92.89%.According to the above results,these solid wastes can be resources.At the same time,that provides a feasible way for the simple and easy treatment,discharging of the standard and reusing of rural domestic sewage.
