3、Dechlorination machine, scope of dechlorination: 0.5-50mg/L。
I Outline:
According to the《Complex Standards of Wastewater Discharge》 （GB8978-1996） implemented since Jan 1 1998, for wastewater treatment of hospital performing chloride disinfection, its residual chlorine must be less than <0.5mg/l，in the process of disinfection, dechlorination is a must to meet the Grade I standard. HLTL series dechlorination machine is designed to meet the needs of wastewater for hospital, its latest dechlorination device has the  following features:
1、Reasonable structure, stable performance, reliable functions, low breakdown ratio, long life expectancy.
2、Convenient application, simple operation, precise measuring, and adjustable, applicable to various working conditions and environment.
3、No expensive easily damaged parts and convenient maintenance.
4、Leading technology, assembly structure, convenient installation and transportation.
5、Low cost.
6、Scope of dechlorination: residual chlorine: 0.5-50mg/l.
II Theory:
1、Chemical theory of dechlorination:
Usually, the disinfector containing chlorine has residual chlorine, it is summation of chloride and chlorine in wastewater of hospital. No matter it is chlorine or chloride, it has oxidation capability. To implement the Grade I standard of discharge, dechlorination is a must, otherwise, secondary pollution would occur. The theory of dechlorination is as follows: Pour certain powerful reducer to ensure it to react with oxidant in an attempt to dechlorine. |
