Abstract

Reusing waste water by appropriate treatment is an effective method for meeting the fresh water demand for construction, cooling, boiler, irrigation and domestic purposes. Greywater (sullage) is the component of domestic waste water which does not contain the toilet effluent. This study aims at treatment of greywater for non-potable purpose, focusing on a non biological treatment technology which is simple, cheap and of portable nature thus having minimum maintenance. Characterization of mixed domestic sullage was done as an initial part of the study. The COD, BOD, TSS, Oil & Grease and Turbidity concentration was found out be 2134, 634, 900, 2309.5 mg/L and 1814 NTU respectively. The primary reason for these high values was gauged to be due to high concentration of cooking oil and detergents in the sample. Based on literature review, a grey water treatment system consisting of coagulation followed by sedimentation, adsorption, filtration and ion exchange is proposed so as to bring the concentration of contaminants upto non potable standards.

将污水用于非饮用目的

废水经适当处理回用是满足建筑、冷却、锅炉、灌溉和生活用水需求的有效方法。灰水(污水)是生活废水的组成部分，不含厕所流出物。本研究针对非饮用灰水的处理，重点研究一种简单、廉价、便携、维护最少的非生物处理技术。混合生活污水的表征是研究的第一部分。COD、BOD、TSS、油脂和浊度浓度分别为2134、634、900、2309.5 mg/L和1814 NTU。测量这些高值的主要原因是由于样品中高浓度的食用油和洗涤剂。在文献综述的基础上，提出了一种由混凝-沉淀-吸附-过滤-离子交换组成的中水处理系统，以使污染物浓度达到非饮用标准。
