Abstract:-Alanthurai has been upgraded with panchayat status. The steady incremental in the panchayat population results in the increase of domestic sewage generation. But still now there is no treatment plant. So it Necessary to adopt a Sewage Treatment Plant with sufficient capacity to treat the sewage.Which is Generated from the various Sources. In this project we designed a sewage treatment plant (Trickling Filter) to treat the sewage water which is dispossed in the noyyal river because of domestic use.For that purpose we collected a water sample from various location like alanthurai, Pooluvapati. We done Physical,Chemical,biological Charaacteritics analysis by various test. The test results are tabulated and compared with standarad value.From the test result we adopted the 3926m3 trickling filter unit with various units likes screening.grint chamber sedimentation tank ,tricking filter unit and sludge digestion tank. By adopting this unit the characteristics values of water get reliable values to the standard value. The project covers the 8140 sq.meter of Alanthurai panchayat for next 15 years till 2032 and its population calculated for that sewage generation.

  1. .INTRODUCTION

    Sewage treatment is the process of removing contaminants from wastewater and household sewage, both runoff and domestic. It includes physical, chemical, and biological processes to remove physical, chemical and biological contaminants. Its objective is to produce a treated effluent and a solid waste or sludge suitable for discharge or reuse back into the environment.

    This material is often inadvertently contaminated with many toxic organic and inorganic compounds. Sewage implies the collecting of wastewaters from occupied areas and conveying them to some point of disposal. The liquid wastes will require treatment before they are discharged into the water body or otherwise disposed of without endangering the public health or causing offensive conditions. As the panchayats have grown, the more primitive method of excreta disposal have gain place to the water-carried sewerage system. Even in the small cities the greater safety of sewerage, its convenience, and freedom from nuisance have caused it to be adopted wherever finances permit.

      Details of the various treatment units

      Sewage generated from only 6 wards.

      In Alanthurai panchayat = 3 Nos.

      In Pooluvapatti panchayat = 3 Nos. Total population in 6 wards (P) = 6582 Nos. Average of increase (x) = 8785 Nos. Average incremental increase (Y) = 5782 Nos.

      1. POPULATION CALCULATION

        Calculation of total population using Incremental increase method

        Po = P + nx + n(n+1/2) y

        P2032 = 6582 +1.58785 +1.5(1.5+1/2) 5782 P2032 = 30601 Nos

        Population in 2032 is 30601 Nos for the design period of 15 years.

      3. RESULT AND DISCUSSION

      4. CONCLUSION

        This project was very useful and it enabled to know various problems met practically in the design of SEWAGE WASTE WATER TREATMENT PLANT. It

        helped to abreast with the various methods used in treating waste water. We gained practical knowledge about design and construction by visiting the field.

        Given the overall sanitation situation in India, there is a need to promote decentralized initiatives in sewage waste water treatment by providing incentives and a supporting policy environment and through capacity building of implementing institutions and stake holders.Decentralized and low-cost options are commonly viewed as solutions for the poor and / or for underdeveloped areas, raising of the profile of low-cost options and alternative technologies as well as of making it 'fashionable' to minimize waste going out of the habitats at micro-level and also at a macro-level at village precincts etc., can go a long way in changing peoples mindsets towards waste -minimization and up -gradation of the environment. More specifically, there is a need for exchange of information and innovations amongst rural and urban bodies and technical support for introducing alternative technologies and processes. Finally, concept Sewage Waste water Treatment plant presents an opportunity to change the mind-set in the waste management sector away from flush and forget systems to recycling in the form of waste to resource systems thus aspiring to conserve and optimize all natural resources such as water.
