Abstract:
Taking sludge,cattle mature,corn stalk as test materials,aerobic compost technology was used in this research,by adding cattle manure and corn stalk in sludge compost.In a reasonable range of C/N,the different proportions of materials were designed with four treatments which tested at the same time,to realize resource utilization of peri-urban waste.The results showed that the temperature,moisture and pH value of every treatment achieved desired results.The data of seed germination test showed that germination index of the treatment A and treatment B (sluge∶cattle mature∶corn stalk of 5∶(2~3)∶4)were both higher that 80% implied that the compost became maturity.The results in comparison showed that the optimum proportion of sewage sludge,cattle manure,and corn stalk was 5∶2∶4.The data demonstrated that the temperature of compost achieved above 55℃ fast and continued 18 days,the moisture was decreased 11.7%,total nitrogen was reduced 0.15%,organic matter content was decreased 28.3%,germination index was 82.1% and pH value was maintained at 6 to 9.Composting of cattle manure and sludge added straw not only realized realize resource utilization but also had more application prospects.
