三氯异氰尿酸生产工艺废水处理回收研究

Study on treatment and recovery of wastewater from trichloroisocyanuric acid production

对三氯异氰尿酸生产过程中产生的氯化钠-氰尿酸废水进行处理和回收,解决了三氯异氰尿酸生产中的废水问题,减少了废水排放。该处理回收工艺由两部分组成:①大孔树脂吸附氰尿酸分子;②二氧化钛一臭氧光催化氧化降解氰尿酸。

In this paper,sodium chloride-cyanuric acid wastewater produced in the production of trichloroisocyanuric acid was treated and recovered,which solved the problem of wastewater in the production of trichloroisocyanuric acid and reduced the discharge of wastewater.The process consists of two parts:Adsorption of cyanuric acid molecules by macroporous resin;②TiO_(2)-O_(3)photocatalytic oxidation degradation of cyanuric acid.
