Abstract
Villupuram district is a one of the largest city with a large number of people. The town is spread over an area of 8.93sq.km. It is the gateway to the southern part of tamilnadu, and a commercial centre dealing with agriculture and food products largely meant for its hinterland. A study on domestic waste water characterization has been performed followed by the design of sewage treatment plant. The present study involves the analysis of pH value, total solids, total suspended solids, hardness, acidity, alkalinity, chloride, chlorine, BOD, DO and heavy metals such as Iron, Copper, Zinc, Magnesium, Nickel, Chromium, Lead, Calcium, Aluminium, Silicon, Potassium. A sewage treatment plant is quite necessary to receive the domestic and commercial waste and removes the materials which pose harm for general public. Its objective is to produce an environmentally-safe fluid waste stream (or treated effluent) and a solid waste (or treated sludge) suitable for disposal or reuse (usually as farm fertilizer).The samplings of the domestic waste from various places have been done in different times of the day to have an average data of the measured parameters. The average values of pH, Turbidity, Acidity, Chloride, Residual Chlorine, Hardness, Total Solid, BOD, DO, Alkalinity, Total Iron Content, Zinc Content, Potassium, Copper, Magnesium, Nickel, Chromium, Lead, Calcium, Aluminium and Silicon are found out. A sewage treatment plant has been designed with the treatment units, like bar screen 26.8m, an aeration tank of dimension 5.7m×11.4m×1m , a collection pit of diameter 26m and depth 5m.
