废水回用是开发水资源的途径之一。除了饮用水的需要,许多行业也需要生产线上的优质水。因此,本研究的目的是研究使用混凝工艺对MorcheKhort工业城镇污水处理厂进行深度处理,曝气絮凝,多层过滤器,并通过紫外线辐射进行消毒,以提高废水的质量并在工业中再利用。在这项研究中,为了研究混凝和絮凝单元以及曝气的影响,过滤,用紫外线(UV)消毒,关于MorcheKhort工业镇污水处理厂二级出水的质量,他们进行了试点规模的手术。使用聚氯化铝(PAC)作为凝结剂。三层砂滤器的分层,从底部到顶部,包括高度为10厘米的粒状二氧化硅,沙子在20厘米的高度,使用高度为70cm的活性炭。考虑了每个单元的输入和输出采样点。通过在流量为1、2、4、6和8(L/min)的五个阶段中重复两次,收集样品以确定COD,TSS,TDS,浊度,pH值,硬度,总大肠菌群,和粪便大肠杆菌。测试结果表明,明矾混凝剂在去除浊度方面的作用几乎与PAC相同,但是在较低剂量下,PAC混凝剂去除有机物的效率高于明矾。研究结果表明,混凝絮凝工艺除浊度的效率,COD,CODTSS,TDS,脂肪占56.88%,46.66%,38%,23.19%,和分别为91.43%。在目前的研究中,对进入砂滤池的废水进行分析,结果表明,在加载速率为1(L/min)的条件下,TSS,COD,CODTDS,脂肪是16。93%,56.84%,50%,5.67%,分别为33.44%。在紫外线消毒装置中,加载速率为1(L/min)时COD的去除效率百分比,TSS,浊度,硬度,总大肠菌群,粪便大肠杆菌占16%,3.45%,3.58%,5.21%,99.88%,和98.37%。凝结和絮凝系统-多层过滤器和消毒可以将化学-物理和微生物参数去除到可接受的水平,以便在先进的净化系统中使用水,也用于灌溉。
Reuse of wastewater is one of the ways to develop water resources. In addition to the need for drinking water, many industries also need high-quality water in the production line. Therefore, the purpose of the present study is to investigate the advanced treatment of the wastewater treatment plant of Morche Khort industrial town using the processes of coagulation, flocculation with aeration, multi-layer filter, and disinfection by ultraviolet radiation to increase the quality of wastewater and reuse it in industries. In this study, to investigate the effect of coagulation and flocculation units along with aeration, filtration, and disinfection by ultraviolet rays (UV), on the quality of the secondary effluent from the wastewater treatment plant of Morche Khort industrial town, they were operated on a pilot scale. Polyaluminum chloride (PAC) was used as a coagulant. Layering of three layers of sand filter, from bottom to top including granulated silica at a height of 10 cm, sand at a height of 20 cm, and activated carbon at a height of 70 cm was used. The input and output sampling points of each unit were considered. By repeating twice in five stages of flow rates of 1, 2, 4, 6, and 8 (L/min), the samples were collected to determine COD, TSS, TDS, turbidity, pH, hardness, total coliform, and fecal coliform. Jar test results showed that Alum coagulant works almost the same as PAC in removing turbidity, but the efficiency of removing organic substances by PAC coagulant is higher than that of Alum at lower doses. The results of this study showed that the efficiency of the coagulation and flocculation process in removing turbidity, COD, TSS, TDS, and fat was 56.88%, 46.66%, 38%, 23.19%, and 91.43% respectively. In the current study, the results of the wastewater entering the sand filter showed that the percentage of removal efficiency with a loading rate of 1 (L/min) was turbidity, TSS, COD, TDS, and fat was 16. 93%, 56.84%, 50%, 5.67%, 33.44% respectively. In the UV disinfection unit, the removal efficiency percentage with a loading rate of 1 (L/min) for COD, TSS, turbidity, hardness, total coliform, and fecal coliform is 16%, 3.45%, 3.58%, 5.21%, 99.88%, and 98.37% respectively. Coagulation and flocculation system-multi-layer filter and disinfection can remove chemical-physical and microbial parameters to an acceptable level for using water in advanced purification systems and also for irrigation.
