1.我国城市垃圾的产量和特点
1.     Production and characteristics of municipal refuse in China.

      近10年,我国城市生活垃圾产生量大幅度增加。中国城市环境卫生协会提供的数据显示,目前我国?#21496;?#29983;活垃圾年产生量为440kg,全国城市垃圾年产生量达1.5亿t,且每年以8%~10%的速度增长,全国历年垃圾存量已超过60亿t,约有2/3的城市陷入垃圾围城的困境。

   城市生活垃圾来源主要是道路清扫、保洁的垃圾,单位、居民区的生活垃圾,商业垃圾,部分工业垃圾和建筑、装修垃圾。我国城市生活垃圾的特点主要是有机物增加,可燃物增多,可回收利用物增多,可利用价值增大。垃圾种类的多样化,尤其是电子垃圾,如电视、电脑、手机、音响等产品日渐成为困扰我国环境的大问题。 

      In the past 10 years, the amount of MSW in China has increased greatly. Chinese City Environmental Sanitation Association to provide the data show that China’s per capita annual garbage production capacity of 440kg, the national city garbage annual yield reached 150 million tons, and the annual growth rate of 10% to 8% to the calendar year, garbage stock has more than 6 million ton, about 2/3 of the city into a garbage Siege predicament.

     The main sources of municipal solid waste are road cleaning, cleaning garbage, unit, and residential area of domestic waste, commercial waste, some industrial waste and construction, renovation waste. The main characteristics of MSW in our country are the increase of organic matter, the increase of combustible substance, the increase of recyclable materials, and the increasing of the use value. The variety of garbage, especially electronic waste, such as TV, computer, mobile phone, audio and other products is becoming a big problem in our country


2.我国城市生活垃圾污染现状

2.     Present situation of urban domestic waste pollution in China

(1)垃圾露天堆放大量氨、硫化物等有害气体释放,?#29616;?#27745;染了大气和城?#26800;?#29983;活环境。

(2)?#29616;?#27745;染水体。垃圾不但含有病原微生物,在堆放腐败过程中还会产生大量的酸性和碱性有机污染物,并会将垃圾?#26800;?#37325;金属溶解出来,形成有机物质,重金属和病原微生物三为一体的污染源,雨水淋入产生的渗滤液必然会造成地表水和地下水的?#29616;?#27745;染。

(3)生物性污染。垃圾中有很多治病微生物,同时垃圾往往是蚊、蝇、蟑螂和老鼠孽生地,这些必然危害人类的身体健康。

(4)垃圾爆炸事故不断发生。随着城市中有机物成分的不断提高和由露天堆放变为集中堆放,只采用简单覆?#19988;?#36896;成产生甲烷的厌氧环境,易燃易爆。

(5)侵占大?#23458;?#22320;。据初步调查,2003年全国668座城市中已有2/3被垃圾带所包围,全国垃圾存占地约80万亩。

(6)60%以?#31995;?#22478;市生活垃圾主要是由小区居民的有机垃圾二次污染后所产生?#27169;?#20063;就是说,小区有机垃圾的不断增多是城市生活垃圾不断增多的源头。

  • Garbage dumps a large number of ammonia, sulfide and other harmful gases released, serious pollution of the atmosphere and the living environment of the city.

  •   Serious polluted water. Garbage is not only a large number of pathogenic microorganism, acid and alkaline organic pollutants will be generated in the process of pilling up corruption, and will be dissolved out of the heavy metal in the waste, the formation of organic substances, heavy metals and pathogenic microorganisms as one of the three sources of pollution, serious pollution, serious pollution of the rain leachate will cause surface water and groundwater. 

  •  Biological pollution. There are a lot of garbage and waste treatment of microorganism, often mosquitoes, flies and cockroaches and mice breeds, which inevitably endanger human health.

  •  Garbage explosion occurred. With the continuous improvement of the composition of organic matter in the city and the change from the open-air pilling up to the concentration o the stack, only the use of a simple cover is easy to cause methane anaerobic environment, flammable and explosive.  

  •   Encroach on land. According to prelim, in 2003 the country’s 668 cities have been surrounded by garbage 2/3, the national waste deposit covers an area of about 800 thousand acres.

  • More than 60% of urban living garbage is mainly produced by the residents of the area after the organic waste generated by the two pollution, that is the growing number of organic waste is increasing the source of urban living garbage. 



3.我国城市生活垃圾处理方法 

3. Urban domestic garbage treatment method in China


     我国城市生活垃圾的处理方式主要是填埋、焚烧?#25237;?#32933;等处理方法,其中,最主要方式是填埋,占全部处理量的70%,其危害是没有实现无害化处理,破坏环境,污染环境。

       其次是高?#38706;?#32933;,占20%以上,焚烧量甚微。处理能力小,处理设施技术低,存在污染隐患多。大多数城市还未将城市生活垃圾进行装袋、分类收集、分类运输和分类处理运用。依然以混合收集为主。部分中小城市垃圾仍然沿用直接倾倒和简易填埋等原始方式进行处理,约有50%的城市生活垃圾直接向外界排放。

    Our city life garbage processing is mainly landfill, incineration and composting treatment method, which is the main way of landfill, the total processing capacity of 70%, the harm is not achieved harmless treatment, environmental damage, environmental pollution.

Followed by high temperature composting, accounting for more than 20%, little incineration. Processing capacity is small with low processing capacity. Mixed collection is still the main. Some of the small and medium-sized cities still use the direct dumping of waste and other simple way to deal with the landfill, about 50% of the city’s garbage discharged directly to the outside world.
