- Abstract:
- The resource disposal of urban domestic sludge has always been a bottleneck problem in our country. Using field research and statistical data analysis methods, this work introduced certain information including the general situation of sewage treatment, the general situation of sludge production, the technical route of sludge treatment, the laws and regulations on land utilization of sludge, the current situation of management and sludge land utilization in Norway. At the same time, combined with the bottleneck of our country in the utilization of sludge land, it proposed countermeasures as following：① Strengthen the top-level design of sludge treatment and disposal laws, policies, standards, specifications. ②Straighten out the connection of management responsibilities among relevant departments from top to bottom. ③ Adapt measures to local conditions and scientifically plan technical routes for sludge treatment and disposal in various regions. ④ Plan and monitor the content of potential organic pollutants in sewage sludge that were of concern at home and abroad. ⑤ Increase the monitoring of heavy metals and organic pollutants in existing regulations. ⑥ Make overall plans on the control of sewage sources. ⑦ Reduce the concentration of pollutants in the final sludge. Based on the above approaches, our country could provide a basis for scientific selection on the direction of the sludge resource disposal after the final treatment.
