Disease takes place frequently, the numerous life of harmful algae, chemicals abuse, Safety of Aquatic Products decline etc..Threat maximum to aquaculture is foster
It grows water body year by year to deteriorate, currently, the worsening and pollution problem of breeding water body environment seriously annoying aquaculture family；Cultivation
Water body deteriorates the generation for leading to the farming disease harms, the aquaculture cost for increasing diseases prevention, curing the disease.
Although thering are some microbial water-purifying agents promoting at present, due to strain quantity is low, of high cost, clean-up effect not
It is good.In the prevalence of problems with：First, the living bacteria count of product is relatively low, dosage is bigger than normal when causing to use, use cost mistake
It is high；Second is that being substantially all the method manufacture using liquid fermentation, fermented product is in liquid, this exists in product preservation holds
The problem of easy microbiological contamination, is relatively difficult to resolve certainly, also inconvenient in transportational process；Third, due to raw material and the mode of production etc., cause
Keep product price higher.
Breeding water body is an enclosed environment, and the methods of traditional single one physical, chemistry or drug can not be from basic
Upper control and elimination water pollution, it is therefore desirable to be administered in conjunction with a variety of methods, filter sundries, inhibit and kill micro- life of causing a disease
Object and harmful algae reduce incidence, reduce chemicals pollution, and to improve water quality and repair breeding water body, this is only currently
Development trend.
Invention content
Present invention solves the technical problem that be that existing breeding water body purification method is not perfect, can not fundamentally control and
Cultivation water pollution is eliminated, and then a kind of sterilization and purification device for cyclic culture water body is provided.
In order to achieve the above object, the present invention adopts the following technical scheme that：
A kind of sterilization and purification device for cyclic culture water body, including aquaculture pond, circulating pump, sedimentation basin, excrement

The water outlet of sedimentation basin is connected to the water inlet of multistage filtering slot, and excrement decomposes the discharge port and multistage filtering trench bottom of tower bottom
Discharge port be connected to fertilizer production apparatus, the water outlet of multistage filtering slot is connected to the water inlet of diafiltration clean equipment, and diafiltration is net
The water outlet for changing equipment is connected to the water inlet of UV illumination disinfection equipments, and the water outlet of UV illumination sterilizing units is connected to ozone and disappears
The water outlet of the water inlet of malicious equipment, ozone disinfection equipment is connected to aquaculture pond, aerator and nutrient solution injection by return pipe
Device is connected to return pipe.
Sterilization and purification device further includes PLC controller, and turbidity transducer is equipped in the water outlet of multistage filtering slot,
It is provided with first flow valve on pipeline between aquaculture pond and circulating pump, on the pipeline between sedimentation basin and multistage filtering slot
It is provided with second flow valve, third flow valve is provided on the pipeline between multistage filtering slot and diafiltration clean equipment, is oozing
It is provided with the 4th flow valve on pipeline between filter cleaning equipment and UV illumination disinfection equipments, in UV illumination disinfection equipment and ozone
It is provided with the 5th flow valve on pipeline between disinfection setting, the 6th flow is equipped between nutrient solution injector and return pipe
Valve；First flow valve, second flow valve, third flow valve, the 4th flow valve, the 5th flow valve, the 6th flow valve, circulating pump,
Aerator, turbidity transducer are connected in PLC controller.By the turbidity of the data on flows of each flow valve and turbidity transducer
Data are transmitted back to PLC controller, the opening and closing of each flow valve are controlled by PLC controller, PLC controller is also into one
Walk the work of control loop transfer tube, aerator.
The inside of excrement decomposition tower is equipped with aeration filled with the nitrifier for decomposing excrement, the bottom of excrement decomposition tower
Pipe, aeration tube provide oxygen by air pump, gas collection equipment are additionally provided at the top of excrement decomposition tower.By in excrement decomposition tower
Nitrifier the excrement of aquiculture animal is decomposed, the pollution of excrement can be substantially reduced.
Level-one filtrate, two level filtrate, three-level filtrate are sequentially filled in multistage filtering slot, culture has on filtrates at different levels
Microorganism fungus kind.The level-one filtrate is made of 42~65% expanded vermiculite and 35~58% sepiolite, the two level
Filtrate is made of the haydite of 3~10% diatomite and 3~7% polyacrylamide and surplus, and the three-level filtrate is
It is made of 5~22% nano active carbon and 78~95% bamboo charcoal fiber.Contain 0.2~1% carbide in the haydite
With 22~37% aluminium oxide, the grain size of the haydite is 0.1~2mm.Culture has microorganism fungus kind on filtrates at different levels, can
