Integrated garbage treatment and utilization method for effectively controlling dioxin

Abstract

The invention discloses an integrated garbage treatment and utilization method for effectively controlling dioxin, which comprises a garbage sorting, drying and storing method, a garbage dry distillation, pyrolysis and gasification method, an integrated treatment and utilization method for garbage ash and combustible gas and an integrated treatment and utilization method for exhaust gas and wastewater, belonging to the field of environmental protection. The method comprises how to effectively control the dioxin and solve the pollution problem of reducing waste water, exhaust gas, waste residue and the like in the garbage treatment process. The solution comprises the steps of sorting and drying the garbage, turning the garbage into renewable resources like combustible gas, tar and the like through integrated treatment of dry distillation, pyrolysis and gasification, comprehensively utilizing the waste residue and waste water for brick making and emitting the exhaust gas up to the standard after treatment. By adopting the technique for garbage treatment, the generation and damage of the dioxin can be effectively controlled, the emission of no waste water, no waste residue and no wastes can be achieved, and the better effect of complete harmlessness, reduction and recycling approximate to 100% can be realized.

Description

technical field [0001] The invention belongs to a garbage treatment and utilization method in the field of environmental protection, and in particular relates to a garbage comprehensive treatment and utilization method for effectively containing dioxins. Background technique [0002] At present, domestic and foreign domestic waste treatment mainly includes methods such as sanitary landfill, composting (composting) and incineration. At present, about 85% of our country is landfill; about 10% is incinerated; about 5% is made (composted) fertilizer, biogas production and other treatment methods. Although the above various methods have their own advantages, there are some problems and deficiencies: 1. Landfill, although it has made some progress compared with non-landfill and random stacking, and its investment and operating costs are lower than incineration, but there are long-term and continuously increasing waste landfills. Occupying land, polluting groundwater for a long ti...
