Abstract

THIS INVENTION EMPLOYS THE SSB TECHNIQUE TO REJUVENATE THE COMPRISING PROCESS AS A REMEDY FOR SAFE FINAL DISPOSAL AND REUSE OF THE DWTP SLUDGE. 8-10DOMESTIC WASWATER SLUDGE (FROM DRYING BED OR LSB) WAS CURED FOLLOWED BY SEPARATION OF FORIEGN PARTICLES AND PREPARED IT MORE OR LESS HOMOGENOUS. THEN IT WAS STERILIZED AFTER ADDITION OF BULKING MATERIALS (SAWDUST AND RICE STRAW) AND OPTIMIZED THE CO-SUBSTRATE, PH, C/N RATIO AND MOISTURE LEVEL. FINALLY THE 6MIXED FUNGAL MIXED INOCULA (APPROXIMATE 3.5 X 103 SPORES/ML) WAS USED FOR INOCULATION AND INCUBATED 75 DAYS FOR BIOCONVERSION . T.HARZIANUMS WITH P.CHRYSOSPORIUM 2094 (T/P) AND T.HARZIANUMS WITH M.HIEMALIS (T/M) WERE FOUND TO BE THE BEST COMPATIBLE MIXED FUNGAL CULTURES FOR THE PROCESS. SUPERIOR COMPOSTS WERE PRODUCES BY T/P AROUND 50-60 DAYS OF SSB. THIS COMPOST COULD PROVIDE 50N REQUIREMENT OF OPTIMAL DOSE OF CORN PRODUCTION. 65-100HIGHER DRY MATTER PRODUCTION WAS ATTAINED BY 50OMPOST PLUS 50N TREATMENT.
