Problems solved by technology

[0005] (3) The demand for organic fertilizers has increased sharply: with the construction of the national ecological environment, the green area has become larger and larger, resulting in a sharp increase in the amount of organic fertilizers. Therefore, the production and utilization of organic fertilizers will cause environmental problems, raw material problems, energy problems, and transportation problems. exacerbated
After its use, there are the following main problems that are not suitable for wide use: (1) the operating load and electricity load of the urban sewage plant

Abstract

The invention discloses a kitchen cleaning wastewater and kitchen garbage comprehensive treatment method. The method comprises the following steps of: collecting kitchen garbage and kitchen cleaning wastewater by using an indoor kitchen cleaning wastewater and kitchen garbage rapid treatment system, and crushing, heating and fermenting the kitchen garbage and kitchen cleaning wastewater; and carrying out solid-liquid separation on the crushed, heated and fermented kitchen garbage and the kitchen clean wastewater by using an outdoor kitchen cleaning wastewater and kitchen garbage collection system, wherein the separated solid is used as an organic fertilizer, and the liquid is used for greening and watering or is discharged into an urban recycled water pipe network. According to the invention, the kitchen garbage can be changed into organic fertilizer after meal on the same day in resident households or dining places, the weight of the kitchen garbage can be reduced by more than half, and the kitchen garbage is directly transported to a designated place for comprehensive utilization by an urban environmental sanitation facility engineering system. An existing large-scale kitchen garbage disposal mode is changed into a household disposal and comprehensive utilization mode, kitchen garbage is changed into recyclable garbage, time and labor are saved, land is not occupied, pollution is avoided, the mode in which the kitchen garbage is conveyed into a garbage landfill, a garbage incineration plant, a kitchen garbage treatment plant and the like for disposal is ended, and the ecological environment is changed.

Description

technical field [0001] The invention relates to the technical field of domestic garbage treatment; a comprehensive treatment system and treatment method for kitchen waste water and kitchen waste. Background technique [0002] 1. Urban issues [0003] (1) Urban water sources are in short supply: Urban development has led to an increase in urban water consumption year by year. The construction of the national ecological environment has made the green area increase year by year, and the green water consumption has increased sharply. The water source of the city needs to be comprehensively considered from the aspects of water conservation, utilization of recycled water, and rainwater interception (sponge city). At present, reclaimed water mainly comes from the advanced treatment water of urban sewage plants. [0004] (2) Kitchen waste: The amount of urban domestic waste has increased sharply. According to the principle of garbage classification, it is divided into four catego...
