The device of sterilization is controlled in journey to the pathogenic microorganism in recycled water.
Background technology
Urban sewage reutilization is one of effective way of alleviation shortage of water resources, dirty by the city after purified treatment
Water can serve as the multiple uses such as reclaimed water, municipal greening water, industrial water, landscape ecological moisturizing and field irrigation,
The fresh water amount of alternative equivalent.The regeneration of sewage had both opened a new water source for stabilization, and discharge of wastewater can be reduced again
The carrying capacity of environment for causing, has important meaning to alleviating water scarcity and improving water environment.However, because municipal sewage comes
Source is complicated, the pathogenic microorganism remained in the recycled water after two grades or tertiary treatment can by different reuse approach directly or
Indirectly cause human health risk.Therefore, the safe and healthy security problem of urban sewage reutilization is dirty large-scale city
Problem demanding prompt solution in water reuse (treatment utilization.
Current recycled water sterilization method is mainly including chlorination, disinfection by chlorine dioxide, ozonization, disinfection by ultraviolet light etc..
Though these methods can kill encountered pathogenic microorganism, cannot the pathogenic microorganism resistant to part effectively sterilized.
As chlorination technology is poor to the inactivating efficacy of Legionella, Cryptosporidium and giardia lamblia stiles, disinfection by ultraviolet light is to adenovirus
Inactivating efficacy is poor.
Recycled water often produces harmful DBPs in disinfecting process, causes certain health risk.Solve cause of disease
The contradiction that bacteria inactivation rate is generated with DBPs.But the correlation that current field of sewage not yet carries out both Comprehensive Controls is ground
Study carefully.It is, therefore, desirable to provide pathogenic microorganism coordinates the safe disinfection technology of control and combinations thereof technique with DBPs.
Sterilization process purpose be kill water-borne infection germ, improve to the nutriments such as organic matter, turbidity, phosphorus and nitrogen and other
The clearance of dissolved matter, improves effluent quality, but is difficult to thoroughly go nutritive salt and suspension, poisonous and harmful in water removal micro
Pollutant and colourity etc., it is difficult to ensure that effluent quality meets the requirement of surface water body.Accordingly, it would be desirable to current processing equipment and
Technique is further improved, and to improve the effect of advanced treatment of wastewater, further improves the water quality of recycled water, and simplify fortune
Row technique, reduces operating cost, the need for preferably meeting society.

Recycled water reverse flow in pond, the ozone tail gas overflowed in pond are discharged after collecting is collected and is detected；
Hypochlorite disinfectant's system be provided with sequentially by the sodium hypochlorite liquid storage tank of pipeline connection, add pump, chlorine
Contact chamber；Sodium hypochlorite liquid storage tank is by pipeline and adds the regeneration water pipe between pump and ozone contact tank and chlorine contact chamber
Road is connected, and the pipeline for carrying out sodium hypochlorite liquid is added, and agitator is provided with chlorine contact chamber, and injection sodium hypochlorite liquid is again
Unboiled water is fully contacted sterilization in chlorine contact chamber, is then discharged by drainpipe.
The utility model is further improved and the additional project of implementation is：
The control system is provided with PLC, and the intake pump is provided with electromagnetic switch valve, intake pump and ozone contact tank
Between pipeline be provided with water ga(u)ge；Gas flowmeter is provided with pipeline between ozone generator and ozone contact tank；

It is provided with fluid flowmeter；The residual chlorine concentration of sodium hypochlorite concentration in detection recycled water is provided with the drainpipe of chlorine contact chamber
Meter；The PLC and the electromagnetic switch valve of the intake pump carry out switch control and are connected, PLC and the current
Gauge, gas flowmeter, fluid flowmeter carry out flow information acquisition and flow control connection；Also with the ozone concentration meter,
Residual chlorine concentration meter carries out concentration information and obtains connection, and its structure is：When the ozone concentration and residual chlorine concentration that obtain are exceeding setting just
During constant value, then ozone dosage is adjusted by gas flowmeter；Throwing by fluid flowmeter to sodium hypochlorite liquid
Dosage is adjusted；And the flow of recycled water is adjusted by water ga(u)ge according to the need for running, whole fortune
Row process is realized automatically controlling.
Using handling process of the present utility model, ozone oxidation can be made full use of to remove and to poison organic matter, reduce regeneration
The risk that Organic substance in water brings, while can effectively kill fraction of pathogens microorganism again.Follow-up chlorination can be well
Control pathogenic microorganism, residual chlorine residue can also suppress the breeding of subsequent process microorganism.
Therefore, the utility model has simple structurally consummate, technological process, good treatment quality, efficiency high, reduced investment, accounts for
Ground is small；Automated condtrol, operating cost can be realized.There is important application prospect in urban sewage reutilization safety guarantee.
