In electrolytic cell, input voltage 330V, output voltage is 0~500V, and input current 150A, output electric current is 0~150A, electricity
The operating temperature for solving pesticide waste liquid in slot is 25~75 DEG C, and operating pressure is -0.05Mpa~-0.01Mpa, micro-vacuum state, electricity
It solves slot and exhaust treatment system is connected by pipeline, above-mentioned operating temperature and operating pressure are controlled by current regulator, auxiliary
It helps temperature sensor and pressure sensor to be measured in real time and transmits data to the current regulator of electrolytic cell；
Pesticide waste liquid in electrolytic cell after being sufficiently electrolysed is transported in coagulating tank by step 3, and lye is added
Adjusting pH value is 6~9, after sodium sulfide technique for removing heavy metal reaction is then added, adds PAC and PAM and carries out coagulating；
Step 4, the pesticide waste liquid after coagulating are pumped to filter press and carry out total pressure filter, the waste water of generation is flow to
Wastewater collection pond, the outer processing of sludge committee of generation.The parameter of the filters pressing of filter press is indefinite, can select different shaped according to processing capacity
Number filter press.
Further, in the step one, homogeneous average processing is the waste liquid of several various concentrations in same tank body
It is spontaneously mutually mixed, becomes the waste liquid of another concentration, after the waste liquid mixing that high-concentration and low-concentration is made using the mechanism of Brownian movement
Concentration is spontaneous to draw close to median.
Further, in the step two, the anode material of electrolytic cell is iron, and cathode material selects graphite electrode or copper
Electrode, cell reaction time are adjusted according to material characteristic, see the table below the parameter enumerated, and the electrolytic cell is closed knot
The exhaust gas of generation is delivered to exhaust treatment system by air-exhausting duct and blower by structure, electrolytic cell, and the exhaust treatment system is adopted
