Problems solved by technology

Although the geographical environment has a certain self-purification ability for solid waste, due to the large amount of discharge, the current solid waste has exceeded the self-purification ability of the environment, and the pollution of solid waste has arisen from this, especially the pollution of groundwater. Therefore, it is necessary to Combining related technologies to treat solid waste

Embodiment 1

[0020] A method for treating industrial sludge solid waste, comprising the steps of:

[0021] S1, mix water: cement to 0.47, water: waste to 0.67, water: medicament to 0.55 to mix to obtain a mixture; the waste is two groups of mixtures of fly ash and incineration fly ash;

[0022] S2. The sludge waste is transported and measured by the shaftless screw conveyor and then enters the mixing mixer;

[0023] S3. Send the cement, waste materials, chemicals and water in S1 to the mixer through their respective conveying systems to S2, and mix them together with the waste materials in the mixing tank; the mixing order of the mixture: sludge waste, cement, water and After the medicament enters the mixer, it is mixed and stirred. Firstly, the medicament and the waste are mixed, and then they are mixed with the cement and then mixed with the cement, and then gradually add water for the overall mixing; this can avoid the Ca 2+ , Mg 2+ The ions compete with the waste for the stabilizing ...

Embodiment 2

[0028] A method for treating industrial sludge solid waste, comprising the steps of:

[0029] S1, mixing water: cement to 0.80, water: waste to 0.50, water: medicament to 4.0 to obtain a mixture; the waste is a mixture of fly ash and incineration fly ash;

[0030] S2. The sludge waste is transported and measured by the shaftless screw conveyor and then enters the mixing mixer;

[0031] S3. Send the cement, waste, medicament and water in S1 to the mixer through their respective conveying systems to S2, and stir together with the waste materials in the mixing tank; the mixing order of the mixture: sludge waste, cement, water and After the medicament enters the mixer, it is mixed and stirred. Firstly, the medicament and the waste are mixed, and then they are mixed with the cement and then mixed with the cement, and then gradually add water for the overall mixing; this can avoid the Ca 2+ , Mg 2+ The ions compete with the waste for the stabilizing factor in the agent, thereby im...

Embodiment 3

[0036] A method for treating industrial sludge solid waste, comprising the steps of:

[0037] S1. Mix water: cement to 0.88, water: waste to 4.00, water: medicament to 5.00 to obtain a mixture; the waste is one or two mixtures of fly ash or incineration fly ash;

[0038] S2. The sludge waste is transported and measured by the shaftless screw conveyor and then enters the mixing mixer;

[0039] S3. Send the cement, waste, medicament and water in S1 to the mixer through their respective conveying systems to S2, and stir together with the waste materials in the mixing tank; the mixing order of the mixture: sludge waste, cement, water and After the medicament enters the mixer, it is mixed and stirred. Firstly, the medicament and the waste are mixed, and then they are mixed with the cement and then mixed with the cement, and then gradually add water for the overall mixing; this can avoid the Ca 2+ , Mg 2+ The ions compete with the waste for the stabilizing factor in the agent, the...

Abstract

The invention discloses an industrial sludge solid waste treatment method which comprises the following steps: proportioning parameters of cement, wastes, a medicament and water, conveying sludge wastes, stirring by a stirring machine, conveying the materials to a building block forming machine through a belt conveyor for forming and maintenance of building blocks, and finally performing landfilling. The method is simple in process, convenient to operate, obvious in treatment effect and extremely low in pollution to underground water; furthermore, generation of solid wastes can be reduced, and the solid wastes can be fully and cyclically used as much as possible.

Description

technical field [0001] The invention belongs to the technical field of solid waste treatment, in particular to a method for treating industrial sludge solid waste. Background technique [0002] In recent years, with the sustained and rapid economic development and the continuous growth of the urban population, the annual discharge of solid waste in our country is showing a trend of increasing. Although the geographical environment has a certain self-purification ability for solid waste, due to the large amount of discharge, the current solid waste has exceeded the self-purification ability of the environment, and the pollution of solid waste has arisen from this, especially the pollution of groundwater. Therefore, it is necessary to Combining with related technologies to treat solid waste. [0003] An industrial park produces a large amount of industrial solid waste. If it is directly buried, it will pollute the groundwater, so it needs to be solidified. After the solid wa...
