The supernatant waste liquid separated after precipitating is discharged from the top of electric flocculation pond, and is delivered in aeration tank and carries out at activated sludge process
Reason；Compressed air is constantly delivered in aeration tank, forces the oxygen in air in the waste liquid being dissolved into aeration tank, is generated simultaneously
It maintains air effectively to contact with water, keeps certain in water in the case where Wastewater Treated by Activated Sludge Process acts on constantly consumption oxygen
Dissolved oxygen concentration, meanwhile, generated in aeration tank it is enough be stirred effect, promote circulating for water, realize that activity is dirty
Mud is mixed with coming into full contact with for waste water, is also able to maintain that mixed liquor has certain movement velocity, is made activated sludge in mixed liquor
In remain suspended state；
(5) mixed liquor of the third water outlet output through aeration tank is transported in the 2nd PH conditioning tank, to the 2nd PH tune
It saves and adds sodium hydroxide, diatomite in pond, using in sodium hydroxide and excessive acid, while sodium hydroxide and diatomite effect,
Diatomite aperture is dramatically increased, enhances specific surface area, absorption property is stronger, more conducively the coagulation of next step；
(6) using force (forcing) pump, (also referred to as relaying water pump, is a force (forcing) pump in system, due to fluid itself in system
Pressure is inadequate, and an increased pump) waste liquid is delivered in coagulating basin from the 4th water outlet of the 2nd PH conditioning tank, to coagulation
Dosing coagulant, flocculation aid in pond will be difficult to the particle precipitated and mutually polymerize form colloid in waste liquid, then with impurity knot in waste liquid
It closes and forms bigger floccule body, to adsorb bacterium and dissolved matter；Floccule body has powerful adsorption capacity, can not only adsorb suspension
Object, moreover it is possible to which absorbed portion bacterium and dissolved matter, floccule body are constantly increased and sunk by absorption, volume；
(7) waste water is delivered in inclined-plate clarifying basin from the 5th water outlet of coagulating basin, and flocculation is added into inclined-plate clarifying basin
Agent, after flocculation sedimentation, the 6th water outlet of inclined-plate clarifying basin exports purified water up to standard, insoluble impurities originally in waste water,
Heavy metal ion, microorganism etc. have been precipitated into sludge, and therefore, the water of the 6th water outlet output is can be with qualified discharge or up to standard
It reuses；The third spoil disposal end of inclined-plate clarifying basin and the second spoil disposal end of coagulating basin arrange sludge from total spoil disposal end together
It puts.
In present patent application, by the raw water tune for being sequentially connected setting in electric flocculation wastewater treatment analog demenstration system
Pond, elevator pump, the first PH conditioning tank, electric flocculation pond, aeration tank, the 2nd PH conditioning tank, coagulating basin and inclined-plate clarifying basin are saved, is realized
Electric flocculation wastewater treatment process simulation to true waste water, stable and reliable operation can obtain at accurate electric flocculation waste water
Law of purification is managed, as shown in Fig. 2, it is to try using the multiple simulation of the electric flocculation wastewater treatment analog demenstration system of the present embodiment
