Shallow lake pond is equipped with solid-liquid separating machine in the sedimentation basin, and the solid-liquid separating machine generates high-strength magnetic field, in the effect of strong magnetic field
Under, the tiny flocculation body generates directed movement, is adsorbed in the separator panel surface of the solid-liquid separating machine, the solid-liquid separating machine
Equipped with special slag unloading device, the body refuse that the separator surface adds up uninterruptedly continuously is detached with water body progress；
The water of the separation continues through pipeline transmission, and activated carbon is equipped in the pipeline, carries out second adsorption flocculation, then
After the sedimentation basin, it is transmitted to a nanometer flotation tank by the pipeline, the nanometer flotation tank is equipped with microbubble generator,
The microbubble generator generates nano bubble and is mixed with water, then by reverse osmosis membrane component, finally by water pass through
The pipeline is for underground reuse.
Preferably, the desalter use include the polymer of mass fraction 1%-35%, 20%-65% organic acid,
Remaining is water.Wherein the strand of polymer is made of styrene and segment and polyether segment made of unsaturated acids copolymerization, and two
Kind segment is connected by ester bond；Organic acid is carboxylic acid, amino carboxylic acid, organic phosphine carboxylic acid or organic phosphine sulfonic.
Preferably, the reaction tank carries out 2-3 times with sedimentation basin step operation.
Preferably, the activated carbon adsorption section, activated carbon accumulator tank, activated carbon stirring and conveying equipment are all installed on described
On pipeline.
Preferably, the reverse osmosis membrane component uses the novel high pollution-resistant Tao Shi composite membranes of imported from America, the film
With very strong antifouling property, the rate of bioaccumulation and raw fouling is very low, and feed pressure is very low, to reduce energy
Consumption.
The beneficial effects of the invention are as follows shaft sump dredging problem can be solved, the safety of shaft sump dredging operation is reduced
Risk realizes well on clear water, substantially reduces elevator pump and the operating load of pipe-line system, reduces drainage system abrasion, reduces dimension
Shield, maintenance cost, power and energy saving, while in underground, water treatment system is upper just regardless of antifreezing heat insulation facility from design, saves trouble
It is easy.
