Problems solved by technology

Asphalt is phototoxic and carcinogenic, coal tar is carcinogenic, and the waste liquid produced by chemical plants is extremely harmful to the human body due to its complex composition.
[0004] In view of the above-mentioned related technologies, the inventor believes that if the liquid or colloid hazardous waste with high viscosity and solid content is not treated, it will cause great harm to the environment; if such hazardous waste is packaged into small packages and directly added to incineration by manual methods, the safety risk will be greater

Embodiment 1

[0032] Transport the viscous, solid-containing liquid or colloidal hazardous waste from ton barrels and oil barrels to the unloading area of ​​the incineration workshop and transport it to the unloading area of ​​the incineration workshop.

[0033] Obtain the component content, viscosity, and calorific value of liquid or colloid hazardous waste and ingredients with high viscosity and solids;

[0034] Hazardous waste and ingredients are mixed in the solid waste compatibility pit, the top cover of the ton barrel or oil barrel is removed, and solids such as cinder and incinerator slag are added to it; the amount of hazardous waste in the ton barrel or oil barrel is controlled so that it can be mixed with the ingredients in the ton barrel or Stir and mix in the oil tank;

[0035] According to the parameters of the hazardous waste materials and the ingredients, put the viscous, solid-containing liquid or colloidal hazardous waste in a tonnage or oil drum container, add ingredients ...

Embodiment 2

[0040] Obtain the component content, viscosity, and calorific value of liquid or colloid hazardous waste and ingredients with high viscosity and solids;

[0041] Hazardous waste and ingredients are mixed in the solid waste compatibility pit, and oil drums or other packages are transported to the side of the solid waste compatibility pit. First put a large amount of coal cinders, incinerator slag, etc. into the solid waste compounding pit, then pour liquid or colloidal hazardous waste into the upper part of the batching pit, and then pour a large amount of coal cinders, incinerator slag, etc., to control the amount of hazardous waste in the ton barrel or oil drum , so as to stir and mix with the ingredients in the ton barrel or oil barrel;

[0042] According to the parameters of the hazardous waste materials and the ingredients, put the viscous, solid-containing liquid or colloidal hazardous waste in the tonnage or oil drum container, add the ingredients in the container, and c...

Abstract

The invention discloses a compatibility treatment process for high-viscosity solid-containing liquid or colloid hazardous waste, which relates to the technical field of hazardous waste treatment. The hazardous waste compatibility treatment process comprises the following steps of proportioning hazardous waste: mixing liquid or colloid hazardous waste which is high in viscosity and contains solids with waste materials such as incineration slag, coal cinder and dried sludge according to a ratio, reducing the viscosity and fluidity of the hazardous waste, and optimizing and blending a heat value. The viscosity of the treated hazardous waste is smaller than 1000 cP, the incineration treatment temperature of the hazardous waste material is 800-1000 DEG C, and the average heat value of the treated hazardous waste material reaches 5300 Kcal / kg or above. Stable, efficient and safe compatibility treatment of liquid or colloid hazardous waste with high viscosity and solid can be realized.

Description

technical field [0001] The present application relates to the technical field of hazardous waste treatment, in particular to a hazardous waste compatible treatment process. Background technique [0002] With the rapid development of industry, more and more hazardous wastes are produced in industrial production, and the types are also diverse, which poses a huge threat to the ecological environment and human health. With the improvement of people's living standards, people pay more and more attention to the treatment of hazardous waste. Among them, the viscous and solid-containing liquid hazardous waste is relatively common. This type of hazardous waste has a wide range of sources and complex components, mainly including coal tar extraction, waste tar produced in the asphalt production process, asphalt, and various chemical plants. Waste liquid produced in industrial production, etc. [0003] At present, most of the process devices for hazardous waste incineration in China ...
