Abstract

The invention discloses a domestic garbage treatment method and relates to the technical field of solid waste disposal. The domestic waste treatment method includes the following steps: S1, pretreating the domestic waste, breaking the bagged waste in the domestic waste, and stacking the broken bag in a fermentation tank; S2, fermenting The garbage accumulated in the tank is covered with a layer of expanded polytetrafluoroethylene composite film to form a closed space. Under aerobic conditions, aerobic bacteria are used for 14 to 17 days of static aerobic fermentation to reduce the moisture in domestic garbage. to 30% to 35%; S3, performing primary sieving treatment on the domestic garbage after aerobic fermentation in the step S2 to obtain the first-level sieve and the first-level sieve, and the first-level sieve The material and the undersize of the primary sieve are recycled separately. The beneficial effect of the invention is that the domestic waste can be decomposed and dried at low cost, the water content in the domestic waste can be reduced, the process is simplified, and the system investment and operation cost are reduced.

Description

technical field [0001] The invention relates to the technical field of solid waste disposal, in particular to a domestic waste disposal method. Background technique [0002] The composition characteristics of my country's domestic waste are affected by factors such as residents' living standards, energy structure, and seasonal changes. Higher moisture content and so on. Most cities in my country use mixed collection methods for domestic waste collection. Except for the pilot cities, there are many cities that do not have domestic waste sorting collection facilities at all. In cities with domestic waste sorting collection facilities, it is difficult for citizens and passers-by to collect waste. Correctly classified and placed, since there is no waste classification treatment measure, it is still mixed and processed in the end. These factors make it difficult to sort household waste in our country, high energy consumption for treatment, easy to cause secondary pollution to the...
