Problems and solutions of urban toxic waste landfill

下面为大家整理一篇优秀的essay代写范文- Problems and solutions of urban toxic waste landfill。本文讲述随着生活水平的提高，越来越多的资源被消耗掉，造成了无数的浪费。

    根据中华人民共和国住房和城乡发展的公告，共有849个废物处理设施，676个卫生垃圾填埋场处理了约1.029亿吨的垃圾，在660个建市的城市中处理了1.589亿吨。 2010年9月下旬（中国建设银行函[2010] 158号）。根据以上统计，垃圾填埋，堆肥和焚烧仍是废物的基本处理方法。另一方面，尽管有限制性政策来管理和控制有毒废物，例如废物分类管理和垃圾填埋场设施的规格标准（“垃圾填埋场污染控制标准”），但对于危险废物，2001-12-28 GB 18598--2001，以及城市固体废物，2008-04-02 No.5）中，大多数地方政府没有有效地执行政策，没有建立废物分类功能系统，特别是在工业废物排放方面。结果，珍贵的自然资源无法再利用。更重要的是，有毒有害废物将通过排放和填埋而造成无法弥补的污染，而无需分类。这是一个案例，说明有毒有害废物在意大利未经处理直接排放到环境中时会发生多么可怕的后果。据一位知情人的描述，意大利政府于2月14日在中国建立了全国性网络。据圣保罗2月11日报道，意大利政府袭击了卡莫拉的犯罪组织基地，并寻找了许多塑料桶的有毒废物以及其他非法工业废物。刘俊玲，“意大利有毒垃圾掩埋的死亡三角”，2014.02.14）此外，那不勒斯地区北部被称为“魔鬼死亡三角区”，因为卡莫拉团伙将有毒的工业废物埋没了治疗并引起癌症病例的惊人上升趋势。根据一个环境组织的统计，那不勒斯地区北部非法埋葬了超过1000万吨的有毒废物，这些排放物赢利数十亿美元，而有害物质土壤和地下水中所含的维生素将严重威胁当地居民的健康。

With the development of living standard, more resources have been taken for consumption and caused countless waste.

    On the basis of the announcement of Housing and Urban-Rural Development of the People’s Republic of China, there were 849 waste disposal facilities，which had 676 sanitary landfill sites processing about 102.9 million tons,processing over 145.89 million tons in 660 formed city by the end of September 2010 (City Construction Office Letter of China, [2010] No.158,). Accordance with the statistics above, landfilling, composting and incineration are still the basic treatment of waste. On the other hand, although there were restrictive policy to manage and control toxic waste, such as management of waste classification and standards of specification of landfill site facilities (“Standard for pollution control on landfill”, for hazardous wastes, 2001-12-28 GB 18598--2001, & for municipal solid waste, 2008-04-02 No.5), most of local governments did not implement policies efficiently and establish a functional system for classifying waste, especially in industrial waste emission. As a result, the precious natural resources cannot be reused. More importantly, the toxic and hazardous waste would cause irreparable pollution by emission as well as landfill without classifying.Here is a case shows how terrible effect happens when the toxic and hazardous waste emission to environment without processing in Italy. Created in China national network February 14, according to the description of a informer,the Italian government assaulted the criminal organizations base of Camorra and sought out many plastic buckets of toxic waste with other illegal industrial waste, Folha de Sao Paulo reported on February 11 (Liu Junling, “The Italian "triangle of death” cased by toxic landfill, 2014.02.14) . What is more, northern territory of the Naples region has been called the “the devil death triangle” because the Camorra gangs buried toxic industrial waste without treatment and caused incredible rise tendency of cancer cases. On the statistics basis of a environmental organization, over 10 million tons of toxic waste have been buried illegal in northern of the Naples region. These emissions won billions of dollars in profits, while the harmful substance contained in soil as well as groundwater would cause serious threat to local residents’ health.

   The effects of burying toxic waste in the ground are far more than those shown above. First of all, landfilling treatment can pollute water resources. In other words, supplies of drinking water are contaminated by refuse from the factory, and it is almost impossible to measure how much sewage and industrial waste end up in our oceans. It is obvious to conclude that how landfill effect our water resources and land resources. Taking Qinghuangdao development area, where used to have a plenty of high quality land, as an example. The land lost to non-agricultural construction, such as industrial facilities, is basically vegetable plots and paddy fields in recent years. The environment and farmland irrigation system had serious problems since local pond was filled up with industrial waste in 2006. Fears of pollution from fiberglass, the local government had to ban rice cultivation in contaminated soil. Furthermore, every time it rains, soaked fiberglass rushes to the village with flood, and many poultries are poisoned by polluted water. These are all directly restrict economical development and influence people living there. Moreover, for the sake of safety and health, people cannot rebuild buildings or facilities on those landfill area any more.

    Secondly, landfill can cause air pollution. Most people think that landfill creates less dust particles than incinerator, but it is not. One study shows that the microorganism concentration in edge of the area is much higher than the central of landfill area, because of frequent human activities (Yue, Xia, Du, Guang, Li, Xu, 2006 S1). In addition, those toxic and hazardous waste created by polyurethane or polyisoprene can never be decomposed by nature. As a result, the air pollution of certain landfill area will go on for a very long time.

    As can be seen, there are so much problems and risks caused by landfill toxic waste, it must have an efficient method for disposal of toxic waste. In my opinion, the Chinese government can draw on the experience of seoul city landfill area and focus on the sustained development with the green ecological idea.

    The seoul city landfill is not a world-class size landfill area. However, the newest technique and concept makes it a successful world model of landfill. Its experience shows that the most important thing is to segregate collection. Once the government encourage citizens to separate garbage, the new polices are announced and strict legislation are passed to ensure the system for sorting waste. Those non-biodegradable litter can be separate and process in result. The second step is to establish a meticulous and scientific transportation management system, because one weak link in the chain can negate many of the advantages that innovation offers. The transportation should be carefully selected in order to reduce pollution in transit. The third step is to disinfect rubbish and every transport in fine details. Destroying odor, removing humidity and sterilizing can be very useful to prevent leakage of pollution in the process. Last but not the least, when garbage has to bury to the ground, percolate must be taken into  great consideration in every procedure during landfill process. Landfill leachate means the sewage filtered out from the garbage during its stacking and landfill through fermentation, the washing of rainwater or the soaking of surface water and groundwater. In other words, landfill leachate is the source of pollution in waste bury process. In order to better address and improve these problems, the seoul city landfill area lays 0.75meters thick layer to prevent secondary pollution effectively. By these processes, a scientific and practical method is established for any landfill project.

On the other hand, the implementation will be affected by different social environment, national economic budget and cultural in China. In my point of view, China government should continue to promote waste classification by setting up more detail standards and laws to regularize waste separation. By planning garbage sorting can easily identify those toxic waste and insulate them from the beginning of process, which can be a efficient way to reduce toxic materials go in landfill. In addition, the garbage sorting process is not as complicated as people used to think. According to a garbage disposal staff, the hazardous material can be completely control and incinerate because of advanced technique. In fact, technology of incineration has already achieve the international standard and creates less dust than landfill. From this perspective, the public’s misunderstanding and worry of the incineration are totally useless. Although some experts still think that there is no 100% harmless way to control waste under present level of domestic technology, incineration is one of the best ways to decrease toxic waste pollution to environment by  evaluate cost and value in how we treat toxic waste. In  other words, if we want to solve the domestic toxic waste landfill in China, the best way is using garbage as resources and burning them to produce electricity at present.  After all, no one can stand with any hazardous processing factory show up in the front of their home and pollute their surroundings.
