Description
Technical field
The utility model relates to Hydraulic and Hydro-Power Engineering field, particularly relates to a kind of fish multiplication pouring station circulating water treatment tower and treatment system.
Background technology
In recent years; the construction of hydropower plant of China enters peak period; but original fish are divided into upper and lower Liang Ge colony by the construction on power station lock, dam; it is made not carry out genetic interchange; weaken the viability of population; in addition; under the trend that attention rate in various circles of society to hydroelectric project ecological environmental protection increases day by day; large-scale hydroelectric project has become social concerns focus at the environment built and produce in operational process and ecological damage; the enforcement of its environment and ecological protection measure is directly connected to the overall image of engineering, even the construction of engineering constraint and operation.In order to protect aquatic ecological, be also the requirement in order to implement the laws and regulations such as " the Fishery Law of the People's Republic of China ", " Water Law of the People's Republic of China ", a lot of hydroelectric project all requires to arrange fish multiplication pouring station at present simultaneously.Its objective is by emphasis, the Species of Rare Fish from Qingdao in the original natural river of enhancement releasing, reduce engineering construction as far as possible to the destruction of aquatic ecological.
Fish multiplication pouring station mainly takes three kinds of aquaculture models, i.e. circulating water cultivation pattern, flowing water culture pattern and still-water pond aquaculture model, because hydroelectric project fish multiplication pouring station engineering many places are in high mountain gorge area, owing to there is no sufficient water source, the operation scheme that a lot of fish multiplication pouring station all adopts recirculated water or flowing water to be combined with recirculated water.Because the discharge having the materials such as Metabolism of Fishes material and bait is abandoned in water in fish farming, suspended substance (SS) can be produced, the pollution substance such as chemical oxygen demand (COD) (COD), ammonia nitrogen, total phosphorus, bacterium, primary/metazoan.Therefore, circulating water cultivation pattern is not abandon water to carry out a simple cyclically utilizing to breeding fish, but one is processed fish multiplication pouring station factory effluent water quality by means such as physics, chemistry, biology, reaches semiclosed or totally-enclosed, the highly intensive mode of production of breeding water reusable edible.But the domestic analysis and research for fish multiplication pouring station circular water treating system are in the blank stage at present substantially, (principal feature is intensive cultivation to only have special fishery cultivating waste water quality, Pollutant levels are high) and the introduction of relevant treatment technique, hydroelectric project fish multiplication pouring station many cultivation Species of Rare Fish from Qingdao and emphasis economy fish, cultivation requires higher, density is low, and pollutent generation is also lower, is different from common fishery cultivating.This just causes a lot of fish multiplication pouring station circulating water treatment design technology also not have essence foundation.
Current fish multiplication pouring station is many with reference to fishery wastewater treatment mode, adopts the method for cascade filtration+multi-stage biological+sterilization+temperature control process.By filter and remove suspended substances (SS) and larger primary/metazoan etc., chemical oxygen demand (COD) (COD), ammonia nitrogen, total phosphorus etc. are removed by biological treatment, bacterium is removed by sterilization, oxygenating machine oxygenation, make water reach the temperature of an applicable fish farming eventually through temperature control process, return fishpond recycle.Zeolite is also widely used in fishery wastewater treatment industry in addition, because zeolite has larger superficial attractive forces and ion-exchange capacity, can the material such as ammonia nitrogen, total phosphorus in the water of effective place to go, in fishery, the method adopting Zeolite Addition powder or arrange zeolite filtration equipment improves breeding water water quality more.Fishery cultivating zeolite needs regularly to be taken out by zeolite again to come into operation with saline soak specially again.
Above the deficiencies in the prior art mainly contain the following aspects:

(2) adopt cascade filtration and multi-stage biological treatment process more, be generally applicable to the fishery water of high-density breeding, running maintenance is comparatively complicated.So many treatment process is not needed for oligosaprobic hydroelectric project fish multiplication pouring station breeding water;
(3) direct Zeolite Addition powder or zeolite filtration equipment is set, the duration of contact of zeolite and water is shorter, reacts insufficient, and pollutent place to go effect is undesirable;
(4) fishery cultivating industry adopts fishery cultivating zeolite regeneration to need zeolite to take out special saline soak, needs labor intensive, usually on zeolite filter side, will arrange special dissolved salt pond, increase floor space;
(5) only zeolite treatment is adopted, not high to the removal efficiency of chemical oxygen demand (COD) (COD);
(6) content of the oxygen in water (DO) after circularly purifying is usually lower.
