How to treat the wastewater produced by aerated brick production line?
September 09, 2021
In the process of aerated brick production line, production wastewater will appear more or less in the stages of raw material mixing, pulping and autoclave curing. In order to implement the strategic development goal of green environmental protection and realize zero pollution discharge of aerated brick production line, it is of great significance to the treatment and reuse of wastewater produced by the production line.
1. Domestic sewage: domestic sewage is mainly the daily domestic water in the plant area. The treatment method of most plant areas is to set up septic tanks in the plant area for treatment, and the treated water is discharged into the sewage pipeline in the plant area.
2. Production wastewater: the waste slurry and wastewater generated in the production process are collected into the waste slurry mixing tank under the cutting machine, and then pumped into the waste slurry tank as pulping water. Another part is the condensate of autoclave and the sewage discharged from boiler room, which can be solved from the source. For the treatment of wastewater produced in the autoclave cooling production process of aerated brick production line, a large sewage tank must be built first. Since the aerated brick block wastewater does not contain inherent substances, it is pumped to the tank after purification, and the slurry is prepared and recycled. It can not only save costs, but also minimize the pollution of nonsense to the environment. Through the above analysis of common wastewater types and treatment methods in the operation of aerated brick production line.
When there is a part of wastewater source in daily production, i.e. rainwater, the rainwater only needs to be drained when the plant is built.
