Waste disposal method

Abstract

The invention discloses a garbage treatment method. The incinerator and the tunnel brick kiln are arranged adjacent to each other, including the following treatment steps: S1, garbage pretreatment, sorting, screening and magnetic separation of garbage, and picking out incombustible substances, The remaining garbage is sent to the garbage pool; S2, incineration, the garbage in the garbage pool is sent to the incinerator for incineration; S3, the treatment of incineration flue gas, the flue gas generated after incineration is sent to the water processor for dust removal and sent to into the tunnel brick kiln, and enter the high temperature section from the low temperature section of the tunnel brick kiln for secondary combustion to remove dioxins in the flue gas, and then discharge them through the smoke exhaust port; Sewage from the water treatment system is sent to the brick mixing tank for mixing, and then sent to the brick forming machine for brick forming, and the formed brick is sent to the tunnel brick kiln for firing and drying. The above method realizes safe and efficient disposal of garbage, has wide application range, high processing efficiency and low cost.

Description

technical field [0001] The invention relates to a garbage treatment method, in particular to a method for treating dioxin and other harmful substances produced during garbage incineration by using a tunnel brick kiln production line. Background technique [0002] The existing waste disposal methods in my country mainly include landfill, high-temperature composting and incineration. The landfill method occupies a large area and has a low degree of waste reduction. It needs anti-seepage treatment, which is easy to pollute the groundwater and surrounding air. The high-temperature composting method is suitable for treating waste with a lot of perishable organic matter, and can realize the comprehensive utilization of some resources, but the quality of compost is not easy to control, and the harmful components often exceed the standard. [0003] At present, garbage incineration is the most commonly used method, but when incinerating garbage, a large amount of dust and toxic and ...

Problems solved by technology

The landfill method occupies a large area, and the degree of waste reduction is low. It needs anti-seepage treatment, which is easy to pollute the groundwater and surrounding air.

The high-temperature composting method is suitable for treating waste with a lot of perishable organic matter, and can realize the comprehensive utilization of some resources, but the quality of compost is not easy to control, and harmful components often exceed the standard

[0003] At present, garbage incineration is the most commonly used method, but when burning garbage, it will emit a lot of dust and toxic and harmful substances, such as highly carcinogenic dioxins, which will cause great pollution to the environment

Although other methods can be used to further treat the incinerated waste gas to reduce the content of harmful substances, the investment cost is high and the whole process is cumbersome, and it is not applicable
