| titleOfInvention | A kind of chemical oxygen demand of waste water detection pretreatment unit and method |
| abstract | The present invention provides a kind of chemical oxygen demand of waste water detection pretreatment unit and method, including reactor, bubble-free aeration membrane module, aeration tube, nitric oxide gas handling system, magnetic rotor and magnetic stirring apparatus, reactor head is provided with exhaust outlet, built-in bubble-free aeration membrane module connects nitric oxide gas handling system by aeration tube, reactor inner bottom part center is provided with magnetic rotor, and outer bottom is provided with magnetic stirring apparatus.Waste water is injected in reactor, open magnetic stirring apparatus and nitric oxide gas handling system, it is 25 times of dioxygen water before Fenton oxidation to control nitric oxide amount in aeration per minute, it is aerated 85~95% that pressure is bubble point pressure, aeration time continues 3 6h, after reaction terminates, 10~30min of stirring is continued to, you can COD is measured by sampling cr .The present invention can eliminate interference of the oxidant to Fenton processed waste water COD testing results, improve COD cr The accuracy of testing result, reflect the actual effect of sewage disposal objective reality. |
