Abstract

The invention provides a household garbage emergency treatment method for a household garbage incineration power plant. The method comprises the steps of weighing, unloading, crushing and magnetic separation. Biological drying is included, an aerobic biological reaction is carried out in a biological drying tank, biological strains are added for deodorization, and the mixture is conveying to a temporary storage warehouse. Transferring is conducted. Percolate collection and treatment are carried out, and the percolate and the deodorized wastewater generated in the previous steps are collected into a percolate collection tank, and then are conveyed into a percolate treatment station for treatment. And odor collection and treatment are conducted, the odor generated in the above steps is collected into a biological filter tank for treatment to meet the emission standard, a plant liquid space atomization spraying and fresh air supply system is arranged to assist in deodorization, and the steps of compression or screening are further included. According to the method, the problems existing in emergency landfill of household garbage at present are solved, the 'neighborhood' effect is avoided, the occupied area is reduced, and the construction cost is also reduced. And moreover, secondary pollution and potential safety hazards to the environment in the carrying process are evaded, and recycling of the household garbage is realized.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, and more specifically relates to an emergency treatment method for household garbage in a domestic garbage incineration power plant. Background technique [0002] With the implementation of domestic waste incineration power generation-based domestic waste treatment policy in China, by the end of 2020, my country will build a daily domestic waste incineration power generation scale of 500,000 tons / day, and it is estimated that 400,000 tons will be built during the "14th Five-Year Plan" period. / day of domestic waste incineration power generation scale, when my country's domestic waste incineration power generation scale will reach 900,000 tons / day. [0003] At present, domestic waste incineration power plants need to carry out regular or irregular equipment maintenance and repair every year. During equipment maintenance, domestic waste is generally temporarily stored in domestic waste ...
