这个方法有投资少，操作方便的优点，但同时存在缺点：（1）堆腐时间长，堆

This method has the advantages of low investment and convenient operation, but it also has disadvantages: (1) The composting time is long, and the composting process usually takes three weeks to one month, resulting in serious sediment pollution. (2) The organic matter is not completely degraded and treated sufficiently, and the residues produced will still cause garbage pollution. (3) The compost product has many impurities, which cannot effectively separate harmful substances such as heavy metals, and long-term use of the compost product will cause soil surface deposition, damage the soil, and damage crops. (4) During the composting process, a lot of nitrogen nutrients will be naturally released, and compounds such as phosphorus and potassium will be naturally degraded, resulting in low fertilizer quality. Farmers are reluctant to pay for it, and the market prospects are slim. In summary, it is not difficult to see that compared with the sanitary landfill method, incineration and incineration power generation methods and composting methods have their own advantages and disadvantages. Therefore, innovative waste treatment methods should not be limited to one or two methods. , But should be classified from the source, and different treatment methods should be adopted according to different garbage attributes.

This method has the advantages of low investment and convenient operation, but at the same time, there are disadvantages: (1) the heaping time is long, the heaping process usually takes three weeks to a month, resulting in serious sedimentation pollution. (2) Organic degradation is not thorough, adequate treatment, the resulting residue will still cause garbage pollution. (3) Composting products have many impurities, can not effectively separate heavy metals and other harmful substances, and long-term use of composting products will cause soil surface sedimentation, damage to soil, damage to crops. (4) In the process of stacking, a lot of nitrogen nutrition will be naturally released, phosphorus, potassium and other compounds are naturally degraded, resulting in low fertilizer quality, farmers do not want to ask, the market prospects are slim. To sum up, it is not difficult to see that compared with sanitary landfill law, incineration and incineration power generation and composting methods have their advantages and disadvantages, so innovative waste disposal methods should not be limited to access to one or two methods, but should be classified from the source, and according to different waste properties to use different treatment methods.

This method has the advantages of less investment and convenient operation, but it also has some disadvantages: (1) the time of composting is long, and the composting process usually lasts for three weeks to one month, resulting in serious sediment pollution（ 2) If the degradation of organic matter is not complete and the treatment is sufficient, the residue will still cause garbage pollution（ 3) There are many impurities in compost products, which can not effectively separate heavy metals and other harmful substances, and long-term use of compost products will cause soil surface deposition, damage the soil and crops（ 4) In the process of composting, a lot of nitrogen nutrition will be naturally released, phosphorus, potassium and other compounds will be naturally degraded, resulting in the low quality of fertilizer, farmers do not want to pay attention to it, and the market prospect is slim. To sum up, it is not difficult for us to see that compared with the sanitary landfill method, the incineration and incineration power generation method and composting method have their own advantages and disadvantages. Therefore, innovative waste treatment methods should not be limited to one or two methods, but should be classified from the source, and different treatment methods should be adopted according to different waste properties.<br>
