Physico–chemical analysis and Management of different combinations of sugar mill and distillery effluents with different animal dungs during vermicomposting by earthworm Eisenia fetida

Abstract

Sugar mill effluents and distillery effluents are harmful for human health and environment. These effluents are having higher amount of suspended solids, dissolved solids, chloride, sulphate, nitrate, and calcium etc. The vermicomposting is suitable way for proper management of these wastes with the help of earthworm Eisenia fetida. After treatment of different combination of these wastes are uses as initial feed mixture for E. fetida during vermicomposting. The physico-chemical property of different combinations of effluents of sugar mill and distillery with animal dungs was observed before and after vermicomposting. There was significant increase in total kjeldhal nitrogen (TKN) 5.8±0.18 g/kg in cow dung, total available phosphorous (TAP) 12.2±0.16 g/kg in DE, total potassium (TK) 16.3±0.36 g/kg in DE, total calcium (TCa) 3.2±0.2 g/kg in SME+BD level and significant decreased in C:N ratio 76.2±1.26 in DE+CD, total organic carbon (TOC) 139.1.13 g/kg in SME (sugar mill effluents), electrical conductivity (EC) 1.3±0.04 and moisture 52.3±1.26 % relative humidity in CD of final vermicompost with respect to initial feed mixture. The temperature of initial feed mixture was significantly decreased after vermicomposting. The pH of initial feed mixture in all the combinations tends to acidic/ neutral nature. The aim of present study to management of sugar mill effluents and distillery effluents as well as determined the chemical compositions of the different combination beds before and after vermicomposting.
