Embodiment Construction

[0023] In order to make readers understand the present invention more clearly, the present invention will be further elaborated below in conjunction with specific examples.

[0024] 1. Principle of leachate backspray treatment process

[0025] First, the leachate to be treated is transported through a high-precision mechanical filter through a water pump (filter pump). After filtration, the suspended particles of the leachate are significantly reduced, and the fluidity is enhanced, which meets the injection requirements. Then it is pumped to the furnace of the incinerator through the water pump (jet pump). According to the real-time combustion situation of the incinerator and the change of the flue gas composition, the appropriate spray volume is calculated, adjusted by the flow regulating device, and finally passed through the gas installed on the furnace. After the mist injector is fully atomized, it is sprayed into the appropriate position of the furnace for uniform evapora...

Abstract

The invention relates to a process for treating garbage percolate, in particular to a process for spraying and treating percolate and aims to provide a reliable and efficient garbage percolate treatment method for spraying the garbage percolate for burning treatment. The garbage percolate can be prevented from polluting the environment and the pollution problem can be solved completely. In order to fulfill the aim, the process for spraying and treating the percolate is provided and comprises the following steps of: collecting the percolate; filtering the percolate; and spraying the percolate. A technical process for spraying, burning and treating the percolate is simple and is convenient to operate. Stock garbage percolate can be decomposed fully or concentrated solution produced in other treatment modes can be treated simultaneously and secondary pollution is avoided; and compared with other treatment modes, the process has low construction, operation and maintenance costs, small floor area and high automatic control degree and is convenient to operate.

Description

technical field [0001] The invention relates to a process for treating landfill leachate, in particular to a process for back-spraying leachate. Background technique [0002] Landfill leachate is a kind of high-concentration wastewater that contains various pollutants (including various toxic and harmful pollutants with complex components) and is difficult to degrade. If it is not treated or treated improperly, it will cause damage to the surrounding environment, especially the nearby groundwater. And serious soil pollution, its treatment has become a hot topic in the global environmental protection industry. For waste incineration power plants, the treatment of landfill leachate has always been a focal issue. With the gradual upgrading of waste resources, the construction of domestic waste incineration and power plants is also on the rise, and the problem of landfill leachate treatment is also particularly prominent. [0003] During the process of stacking and landfilling...
