Background and Objective: the aim of this survey was prevent the environmental pollutant, urban sewage sludge management and vermicompost production by beneficial usage of rice straw as an agricultural trash which burn in arable rice grounds. Method: This study conduct to evaluate the nutrition matter consist of nitrogen, phosphorus, potash in (21±4˚c) temperature and pH (7±0.5) in urban sewage management, and provided the suitable vermicompost by pure dehydrate urban sewage mixed in rice straw as compared with rice straw and manure complex and pure dehydrate urban sewage (control; PDUS) containing E. feothida from three replication in 8 week. At the end of the test amount of nutrition matter was compared between treatments in (p<0.05) value. Findings: Results shown, significant difference between treatment and reduced the amount of nitrogen, phosphorus, potash (p<0.05).So, the best level of nitrogen (1.21±022)% ,phosphorus(0.69±0.03)% and potash(0.07±0.01)% was determined in rice chaff and manure complex treatment. After this treatment, the PDUS mixed by rice chaff group had best point than control group innutrition matter except in amount of potassium. In potassium level after rice chaff and manure complex, control group was set in second station and the lower point was in dehydrate urban sewage mixed by rice chaff group. Discussion and Conclusion: Followed our results, we can say that rice chaff was more effective to produce the urban sewage vermicompost. Also this is good agricultural manure cause to best nutritional value and it could be help us in urban sewage management.
