The method and device of recycling.
Background technique
With rapid development of economy, water pollution is also on the rise, wherein since industrial wastewater largely discharges, it is especially high
Concentration acidic and alkaline waste water and wastewater discharge containing harmful bacteria constantly increase, and cause the eutrophication by water water body, algae and micro- life
Phenomena such as object mass propagation, oxygen in water consume excessively, eventually lead to mortality, the water body fouling of fish occurs often.
The problem of processing of industrial wastewater caused by chemical company is a headache of wastewater treatment in the prior art, in order to obtain
Good clean-up effect, more commonly used mode is the processing method of physics or chemical industry in the prior art, but both processing sides
The consuming of infrastructure and the equipment investment of method is all bigger, and maintenance cost is also expensive, it is often necessary to repair, replace component etc..
Epoxy wastewater treated most waste water through Sewage Disposal handle it is up to standard after direct emission, but in water resources shortage day
Beneficial severe is current, and such processing mode will cause the serious waste of water resource and the secondary pollution of environment.Current epoxy is useless
The main reason for putting of directly running in cannot be recycled after water process is up to standard is: discharge water after sewage treatment is more or less to be contained
The reasons such as micro suspended matter, microorganism, color number be deeper.
The patent of invention of 201610113469 .5 of Patent No., a kind of waste water treatment system of the disclosure of the invention, including oxygen
Change equipment, further includes heating room and for the heating device being internally heated for heating room, the heating room to be provided with
Waste water inlet and wastewater outlet, the inlet communication of wastewater outlet and the oxidation furnaces.Because increasing heating room and can be to adding
The heating device that hot cell is internally heated, waste water can heat in room by heating device before entering oxidation furnaces
It is heated, the raised waste water of temperature enters in oxidation furnaces, avoids the temperature phase for newly entering waste water in oxidation furnaces
It is too low to the temperature inside oxidation furnaces, and temperature is higher, more conducively advanced oxidation reaction, and then can effectively guarantee to aoxidize
Advanced oxidation reaction can be effectively performed in equipment, while improving oxidation rate.So the sewage treatment equipment can be effective
Ground solves the problems, such as that waste water advanced oxidization effect is bad, and disadvantage is to need to heat, and Acclimation temperature ability is weak.

It is mixed in proportion in device, is filtered purified treatment by purification pot, purified residue is drained into sludge through sludge pump
Chi Zhong, scavenging solution after filtering is discharged into condensate water circulatory pond to be made as condensation cooling water source in the circulatory system of consersion unit
With the effect of solenoid valve used in device, residual cake valve is control liquid, residue flowing velocity or inlet, discharge rate
Size.In addition circulation temperature lowering system causes equipment since temperature is higher, long-play can generate scale in some equipment
Utilization efficiency is low, and exothermic reaction heat spreader is bad in reaction kettle, causes reaction vessel over-temp and over-pressure and material spray occurs and even sends out
The danger of raw explosion；And the recirculated water of the ion containing sodium hypochlorite used in the present invention can be played and be carried out to circulation
