Problems solved by technology
[0008] The purpose of the present invention is to provide a kind of special equipment for the resource-recycling treatment process of physical and chemical sludge, aiming at the technical defects that the existing sludge treatment technology has low treatment efficiency for physical and chemical sludge and is prone to secondary pollution. The mud undergoes a treatment process of primary dissolution, primary dehydration, secondary dissolution, secondary dehydration, tertiary dissolution, and tertiary dehydration. The moisture content of the finally obtained inorganic sludge is below 60%, and the contents of potassium, sodium, and chlorine are all reduced. To about 0.06%, it can be used as cement kiln ingredients, which reduces the environmental pollution and land occupation caused by sludge landfill, and completely realizes the resource utilization of sludge

A special equipment for the washing and recycling process of physical and chemical sludge, which adopts the method of primary dissolution, primary dehydration, secondary dissolution, secondary dehydration, tertiary dissolution, and tertiary dehydration to treat physical and chemical sludge, and finally obtains The moisture content of the inorganic sludge is below 60%, and the content of potassium, sodium, and chlorine is all reduced to about 0.06%. It can be used as a cement kiln ingredient, reducing the environmental pollution and land occupation caused by the sludge landfill. At the same time, the filtrate is processed Impurities are removed and purified, evaporated and crystallized, and the salt products obtained can be exported, which completely realizes the resource utilization of sludge.
Description
technical field [0001] The invention belongs to the technical field of waste resource treatment, and specifically relates to special equipment for the process of washing and recycling physical and chemical sludge. The physical and chemical sludge is dissolved, washed and dehydrated to reduce the dissolved salt content of the sludge and can be used as cement. The kiln ingredients are used, and the filtrate is purified and evaporated to crystallize at the same time to obtain salt products, which realizes the reduction and resource utilization of sludge. Background technique [0002] In the field of water treatment industry, especially in modern industrial wastewater treatment, due to the complex composition of wastewater, it is difficult to biodegrade, so physical and chemical methods are commonly used methods for wastewater treatment. However, in the process of physical and chemical treatment, a large amount of physical and chemical sludge is produced. Physical and chemical s...
