Processing method.
Background technique
Currently, the sanitary sewage that generates in navigation of ship is generally used after biochemical treatment reaches discharge standard both at home and abroad
It is discharged into sea, biochemical processing process utilizes microbial degradation organic matter, continuous constant water inlet is needed, so the equipment of sewage treatment
Volume is big, however ship rides the sea, and equipment load is smaller more advantageous, while operator is limited on ship, operates simpler
Equipment operate normally a possibility that it is bigger, treatment effect is also just more obvious.Problem of the existing technology is: equipment load
Weight, occupies ship and the intracorporal space of ocean structure is big, and the processing time is long, fluctuation of service, is easy to cause dirt to marine environment
Dye, and processing capacity is low, and operating cost is high.
Summary of the invention
The purpose of the present invention is in view of the deficiencies of the prior art and provide a kind of sanitary sewage electrochemical process for treating,
Using the electrolytic cell of claustra structure, cell reaction is carried out using seawater as electrolyte, chlorine and the sodium hydroxide for being electrolysed generation are raw
Make sanitary sewage qualified discharge, work by sodium hypochlorite by organic matter degradation and sterilizing in sanitary sewage at sodium hypochlorite
Skill is simple, and device structure is compact, and degradation of organic substances and sterilizing carry out simultaneously in same equipment, easy to operate, and operation is steady
Calmly, expense is low, and occupancy ship and the intracorporal space of ocean structure are small, reliably, effectively protects marine environment.
Realizing the technical solution of the object of the invention is: a kind of electrochemical process for treating of sanitary sewage, its main feature is that the party
Sanitary sewage is entered electrolytic cell with sea water mixing and is electrochemically reacted by method, and the chlorine and sodium hydroxide for being electrolysed generation generate secondary
Oxidation reaction occurs for the organic matter in sodium chlorate, sodium hypochlorite and sanitary sewage, makes organic matter while obtaining degradation to life
Sewage carries out sterilizing, and specific processing step is as follows:
A, the electrochemical reaction of sanitary sewage
Sanitary sewage and seawater are pumped into electrolytic cell by macerator pump and sea water pump respectively by the volume ratio of 1:15~25 simultaneously and carry out electricity
Chemical reaction；The electrolytic cell is the cabinet of titanium alloy production, interior to be equipped with positive electrode plate and the interlaced setting of negative electrode plate
Claustra structure, when sanitary sewage and seawater flow through claustra structure, will electrolysis generate chlorine in closed claustra structure with
Sodium hydroxide generates sodium hypochlorite, and sodium hypochlorite flows out electrolytic cell in company with sanitary sewage；
B, the oxidation reaction of organic matter
Above-mentioned sodium hypochlorite is sent into the oxidation reaction that letdown tank carries out organic matter in company with the water outlet of sanitary sewage outflow electrolytic cell；
The baffling area and buffer area constituted in the letdown tank equipped with folded plate, baffling area side are equipped with water inlet pipe mouth, and buffer area side is set
There is effluent pipe mouth, electrolytic cell is discharged under the hydraulic disturbance in baffling area, and javelwater is solved the active oxygen of release and is lived dirty
Organic matter in water is sufficiently mixed, and further carries out organic matter degradation and sterilizing to sanitary sewage, slow after fully reacting
It rushes in area and carries out reduction reaction to balance still unreacted chlorine residue, through organic matter degradation and sterilizing with the sodium sulfite being added
Sanitary sewage it is up to standard after by emptying pump from effluent pipe mouth be discharged.
The present invention has structure simple compared with prior art, and densification degree is high, and sewage treatment capacity is big, degrades organic
Object and sterilizing carry out simultaneously in same equipment, and simple process is easy to operate, stable, expense is low, and occupy ship
Oceangoing ship and the intracorporal space of ocean structure are small, reliably, effectively protect marine environment.
Detailed description of the invention
Fig. 1 is figure of the embodiment of the present invention
Fig. 2 is the A-A sectional view of Fig. 1.
Specific embodiment
Refering to attached drawing 1, the present invention is by sewage receiving slit 2, sea water pump 3, letdown tank 6, dosing tank 7, macerator pump 8, electrolytic cell 9
