Problems solved by technology

At present, various solid waste projects mostly exist in the mode of separate site selection, separate construction, and decentralized layout. Due to the need to keep a relatively large safety distance and stay away from residential areas, it is difficult to select sites and land, occupy too large an area, and distribute pollution sources too much. wide

Embodiment Construction

[0022] A method for co-processing municipal solid waste provided by the present invention specifically includes the following steps:

[0023] Step S1: After the food waste is pretreated, the sieve is obtained after natural sinking, bag breaking and sieving;

[0024] Step S2: drying the sludge from the sewage plant to obtain dried sludge;

[0025] Step S3: Finally, mix the sieved material and dried sludge into domestic waste for stirring and leaching, and then incinerate. The flue gas generated by incineration is converted into steam for power generation, and part of the steam is used for kitchen waste treatment and sludge treatment time heat source.

[0026] Among them, in step S1, the food waste is firstly pretreated, and then the sieves obtained after natural sinking, bag breaking and sieving include:

[0027] Step S11: After entering the factory, the food waste is pretreated, naturally settled and drained, the bag is broken with a bag breaking machine, and sieved through ...

Abstract

The invention discloses a method for co-processing municipal solid wastes. The method comprises the following steps: pretreating kitchen wastes, performing natural bag settling and breaking, screening, thereby obtaining the oversize product; drying the sludge discharged from a sewage plant, thereby obtaining the dried sludge; and finally, mixing the oversize product and the dried sludge into household garbage for stirring, infiltrating and combusting, performing heat exchange on the flue gas generated by combustion so as to form steam for generating power, and taking one part of steam as a heat source in the process of treating the kitchen wastes and sludge. According to the method for co-processing municipal solid wastes provided by the invention, the oversize product of the kitchen wastes can be doped into the household garbage, the dried sludge is subjected to incineration disposal, the multiple municipal solid wastes are integrally co-processed, and the aim of recycling the resources is achieved due to reasonable flue gas utilization, so that the energy, materials and water resources are recycled in the process of treating the municipal solid wastes, and secondary pollution can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a method for co-processing urban solid waste. Background technique [0002] With the acceleration of urbanization, the increase of population size, and the upgrading of residents' consumption, the amount and types of urban solid waste such as municipal solid waste increase accordingly, and the environmental protection standards, technical requirements, and difficulty of site selection for urban solid waste treatment facilities are also increasing Gradually improve. At present, various solid waste projects mostly exist in the mode of separate site selection, separate construction, and decentralized layout. Due to the need to keep a relatively large safety distance and stay away from residential areas, it is difficult to select sites and land, occupy too large an area, and distribute pollution sources too much. wide. Therefore, taking into account the needs of various t...
