摘要
焚烧处理已成为我国垃圾处理的主要方式,并形成了“焚烧为主,填埋托底”的垃圾终端处理格局。“十三五”收官与“十四五”起舞之年,对垃圾焚烧发电厂给水与给水处理系统、污废水排水及其处理系统的设计进行了系统的分析。预计在“十四五”期间,污水、生活垃圾、污泥、餐厨垃圾等协同处理模式及“去工业化”“邻避”化“邻利”的设计理念将得到深入的发展与践行。
Incineration has already become the main way to dispose the municipal solid waste in China and the terminal MSW disposal pattern with“incineration as the main way and landfill as the last choice”has been formed as well.In the transitional year between the 13th and 14th Five-Year Plan,a systematic analysis was made on the design of water supply,water discharge and their treatment systems in MSWI plants.It was found that the two main water resources of the production water were surface water and reclaimed water,which were treated by the integrated water purifying facility and reclaimed water treatment system respectively;with the environmental protection efforts being enhanced,“zero discharge”of wastewater in the MSWI has become a trend;the new four-step treatment process of“pretreatment+biochemical treatment+advanced treatment(membrane treatment)+concentrate reduction”becomes the mainstream leachate treatment process in MSWI plant.Meanwhile,the application of mechanical vapor technology like mechanical vapor recompression(MVR)and mechanical vapor purification compression(MVPC)makes the total quantitative treatment of leachate possible.It is predicted that the further development and practice will be achieved in the co-processing pattern about wastewater,MSW,residual sludge and food waste and the design concept of the deindustrialization and“NIMBY TO BIMBY”during the 14th Five-Year period.
