Then enters a PAC reaction tank 22 and a PAM reaction tank 23, and the tank has the function of adding proper PAC and PAM medicaments to enable particles in the sewage to be rapidly agglomerated.

Then enters an adjustable electric folded plate precipitator 5, a large amount of organic matters, suspended matters and heavy metal ions in water can be removed in the device, the suspended matters adsorbed on a polar plate can be sunk to the bottom of the tank by intermittent power failure, and proper Q can be added into a transfer tank 4 before entering the electric folded plate precipitator 5₃And H₂O₂Most of the organic matter can be deoxidized and then the sludge is pumped into a sludge concentration tank 11 by a sludge pump 10. The supernatant of the electric folded plate precipitator 5 enters a sand filter 71, free particles which cannot be filtered in the precipitator can be filtered in the tank, then the supernatant enters a carbon filter 72, and the activated carbon in the tank can adsorb residual organic matters and heavy metal ions. Finally, the sewage enters a clean water tank 73, a small amount of disinfectant is added for sterilization, and the effluent can be reused in a workshop.

After the sludge enters the sludge concentration tank 11, a certain amount of lime is added for a certain time for precipitation, the supernatant flows back to the reaction tank 2 through the return water pipe 13 for continuous circulation treatment, and the sludge is pressed into the filter press 15 by the sludge discharge pump II 14. After filter pressing, filtered water flows back to the reaction tank 2 through the water return pipe 13 for continuous circulation treatment, and mud cakes are collected by solid waste companies.
