Automatic Large Type Sodium Hypochlorite Wastewater Treatment For Sewage Plant
Generation principle:
The revolutionary CNJY-S series sodium hypochlorite generator is a newly and for on-site product of NaClO equipment and use for all kinds of needed NaClO disinfected. The sodium chloride solution under the certain voltage effect of the cell, a series of electrochemical reaction within the cell and the resulting solution is the NaClO solution. The main process can be simplified as follows:
NaCl+H2O+DC→NaClO+H2 ↑
The electrode reaction:
anode:2Cl--2e→Cl2
cathode:2H++2e→H2
solution:2NaOH+Cl2→NaCl+NaClO+H2O
Product system:
Brine preparation part: Including water softener, dissolving tank, salt feeder, mixing
system , etc.
Generation Part : Including Generator, Heated Exchange , Rectifier , Control Cabinet , etc.
Storage Tank Part : Including NaClO tank , blower fan , Level gauge , Hydrogen gas detector , etc
Delivery Part: dosing Pump, flow meter, residual chlorine detector, etc
The advantage analysis of on-site sodium hypochlorite
Compared with traditional disinfection methods:
Water sewage treatment plant 60000 T/D, available chlorite dosing quantity 3 PPM, need 180kg everyday.
Disinfection method | On-site | commercial | UV | |
Making process | It produce a solution of strengths 0.8% and the only PH of 9 and making it less likely to cause scaling | By-product of the chlor-alkali industry, the concentration of 10%, containing excess alkali and harmful impurities | Generally within the ultraviolet fluorescent mercury released from plasma discharge. | |
attenuation | Without attenuation | Attenuation of 5% per day, and also cause excessive Chlorate in dinking water | Usually by the turbidity impact, gradually weakened life six months after the exposure time is short, there is no continuous disinfection capacity, and there may be a problem microorganisms resurrection light, preferably in the case of process water for immediate use, no secondary pipeline better raw water pollution and biological stability of the situation (generally require organic matter content of less than 10μg/L) | |
safety | Safety disinfection method, environmental non-toxic, liquid dosage | Dangerous articles. Risk during transport and storage and easily caused degradable when storage. Short time storage and high transport costs. Liquid dosing | Quartz tube require regular cleaning, heavy workload, each lamp should change the water. Easy to do radiation uniformly over the entire processing space, shaded area exposure | |
Disinfection by-products | Due to weak in chlorine oxidation ability, three material are less, and combined additive, ammonia, potassium permanganate, less by-products | The raw |
