Abstract

The invention relates to a casting coating prepared from semi-coke wastewater and a preparation method of the casting coating. The casting coating comprises the following components: the semi-coke wastewater, industrial formaldehyde, polyvinyl alcohol, calcium bentonite, quartz powder, white emulsion, sodium carboxymethylcellulose and a de-foaming agent. Heat carried by the wastewater is used as a heat source and the semi-coke wastewater is directly prepared to the casting coating; and an external heat source is not required so that economical efficiency and environmental protection are realized. The prepared casting coating has the characteristics of strong chemical stability, good suspension, high strength, good leveling property and the like; and after the coating is dried, a surface coated with the coating is smooth and clean and has no foam, so that the coating can be widely applied to a coating casting industry.

Description

technical field [0001] The invention relates to a foundry coating prepared by using blue carbon waste water and a preparation method thereof. Background technique [0002] Blue carbon waste water is the waste water produced in the process of coal processing and production of blue carbon, coal tar and coke oven gas in the process of medium and low temperature dry distillation (about 650 ℃). Chemicals and ammonia nitrogen and other toxic and harmful substances. The content of COD, ammonia nitrogen and phenolic substances in blue carbon wastewater is high. 3 -N>2000 mg / L, it belongs to refractory high-concentration organic wastewater. [0003] At present, the treatment methods of blue carbon wastewater include adsorption method, activated sludge method, incineration method, oxidation method, biochemical method, steam ammonia dephenolization-SRB method, etc. Among them, the adsorption method has high cost, difficult adsorption and regeneration, and is not suitable for high...
