【摘要】：隨著我國城市建設(shè)的迅速發(fā)展,城市生活垃圾量每年按照百分之十幾的速率遞增,因此對城市生活垃圾的合理化處理尤其重要。處理不當,就會造成“垃圾圍城”的局面,而垃圾處理的同時也給環(huán)境造成了一定的污染,也被越來越多的人意識到,其中的臭氣、滲濾液污染影響比較突出。一般的垃圾場運行都在10---20多年,這樣長期性的市政項目,如果環(huán)保處理項目不達標,將會造成持續(xù)性、累計性的污染。其中的垃圾滲濾液是否處理達標排放是衡量一個垃圾填埋場是否為衛(wèi)生填埋場的重要指標之一。對于垃圾滲濾液的處理,不僅需要對垃圾滲濾液的處理工藝(包括建設(shè)成本和運營成本)進行深入的分析,也需要對垃圾滲濾液的源頭、收集、處理、排放流程進行全面的通盤兼顧,并當成滲濾液運營的一部分。本文引用已經(jīng)建設(shè)好的工程(處理工藝MBR+NF/RO),通過建設(shè)成本、建設(shè)周期、建設(shè)難度等,加上運營期間的成本分析(電費、人工費、藥劑費等)、折舊、維修費等,以處理效果為前提,對主體工程進行綜合分析；同時將垃圾滲濾液的源頭、收集、處理、排放的工藝,也納入到滲濾液處理的運營管理過程中,對滲濾液所能經(jīng)過的路徑進行整體考慮,根據(jù)當?shù)氐沫h(huán)境、氣候,選擇合適的主體工藝并相應(yīng)地完善各個其他可能影響到的環(huán)節(jié)。同時通過參觀考察,本文中也引用了其他處理工藝的比對,例如MVC、A/O+Fenton,對工藝進行了簡易介紹,以便于有更多的選擇,同時也可以根據(jù)垃圾填埋場的填埋年限,對工藝做出靈活的調(diào)整。工程實例表明,處理工藝：MBR+NF/RO可以首先選擇,當然,各個地方的實際情況不同,需要根據(jù)實際情況具體情況具體分析。同時二[藝可以進行靈活的組合,工程實踐證明,生化最好先考慮,后續(xù)可以DTRO、MVC、Fenton,在處理效果保證的前提下,需要跟建設(shè)投資緊密相連,從后期運行成本(電費、藥劑費、人工費)、折舊、維修角度來看,從山東、廣東、廣西、江西、山西工程實踐證明處理工藝：MBR+NF/RO相對比較合適,別的成本相對高。在主體工藝選擇確定的情況下,需要從滲濾液產(chǎn)生的源頭開始,包括收集、庫區(qū)內(nèi)的分區(qū)規(guī)劃、雨污分流(庫區(qū)周邊排水溝、HDPE膜隔離降雨等)、地下水及時觀察提升排放、處理后滲濾液達標排放等進行綜合的考慮,一起納入到滲濾液日常運營管理中,以便于更好的掌握滲濾液的動態(tài)變化,及采取更合適的工藝調(diào)整。
[Abstract]:With the rapid development of urban construction in China, the amount of MSW is increasing at a rate of more than ten percent per year. Therefore, the rational disposal of MSW is particularly important. Improper disposal will lead to the situation of "garbage siege", while garbage disposal also pollute the environment, and more and more people realize that the odor and leachate pollution is more prominent. The operation of the general waste yard is in 10---20 for many years. If such a long-term municipal project fails to meet the standard of environmental protection, it will cause continuous and cumulative pollution. Whether the landfill leachate is one of the important indicators to measure whether a landfill is a sanitary landfill or not. For the treatment of landfill leachate, need not only to the treatment process of landfill leachate (including the construction cost and operation cost) to conduct in-depth analysis, but also the need for the source, leachate collection, treatment and discharge process to conduct a comprehensive overall consideration, and as a part of the leachate operation. This paper has good reference construction engineering (treatment MBR+NF/RO), through the construction cost, construction period, construction difficulty, coupled with the analysis during the operation costs (electricity, labor costs, drug fees), depreciation, maintenance fees, the treatment effect is the premise of the comprehensive analysis of the main project; at the same time the garbage leachate source, collection, treatment and discharge process into the operation and management process of leachate treatment infiltration in the path of the leachate can after the overall consideration, according to the local environment, climate, select the main process and the corresponding improvement of each other may affect the link. At the same time, through the tour inspection, this article also quoted the comparison of other treatment processes, such as MVC and A/O+Fenton, and introduced the technology briefly, so that more choices can be made, and the process can be adjusted flexibly according to the landfill date of landfill. The engineering example shows that the treatment process can be chosen first: MBR+NF/RO, of course, the actual situation in different places is different, so we need to make a detailed analysis based on the actual situation and specific circumstances. At the same time [two art can be flexible combination of engineering practice, it is best to consider the follow-up biochemical, DTRO, MVC, Fenton can be guaranteed, in effect, need to construction investment are closely linked, from the late running costs (electricity, chemicals cost, labor costs, depreciation, maintenance) perspective, certificate processing from Shandong, Guangdong, Guangxi technology, Jiangxi, Shanxi: MBR+NF/RO engineering practice is relatively appropriate, other costs are relatively high. In the main process of selection is determined, the source needs arising from leachate, including collection, area zoning, rain and sewage diversion (surrounding reservoir drainage ditch, HDPE membrane rainfall), groundwater discharge, improve timely observation after treatment of leachate discharge and comprehensive consideration, together into the leachate daily operation management, in order to better grasp the dynamic changes of leachate, and adopt more appropriate adjustment process.
