The outlet of sewer 9 after processing of sewage afterwards flows out to sewage disposal system.
Power consumption is also different because electric conductivity is different for different sewage.By de- (chlorine) 1KG power consumption 1KW*H, using at night
Paddy electricity situation operation, economic benefits.User can expand the scale of production to needing to reclaim the occasions of a large amount of alkali lye, be
Reduce electricity cost in production, it is proposed that focus utilization night 22：00-8：00 paddy electricity optimistic time, operating cost can save nearly one
Half.
The utility model using electrochemical theory research and development sewage dealkalize, dechlorination ion unit, can easily containing alkali, contain
Chlorine ion wastewater is separated in a manner of liquid caustic soda, liquid chlorine, and the liquid caustic soda, liquid chlorine can be with direct reuses in chemical products production technology
In, production cost has been saved, it is superior to wastewater treatment efficiency, because the removal of alkali, reuse, reduce substantial amounts of neutralization acid
Liquid, reduce the generation of substantial amounts of salt, sewage disposal is up to standard very convenient, and operating cost is very cheap, energy-conserving and environment-protective, economy effect
Rate is very outstanding.
