Description

Sea-water purifying device

Technical field

The utility model relates to a kind of quality purifying device for water, specifically sea water filter can be purified, and dispels impurity, the sea-water purifying device of oxygenation sterilization and disinfection.

Background technology

Along with improving constantly of living standards of the people; the precious marine product fish and shrimp of sea farming; extremely consumers in general's favor; thereby give the flourish boundless vital force of having injected of mariculture industry; but because the current big climate and the artifact pollution of environment are on the rise; bring unprecedented difficulty to mariculture industry; the raiser does not stint and drops into a large amount of funds and buy the quality that sterilizing agent and antibiosis are usually kept seawater; because the very different generation that has caused the situation of the secondary pollution that much weighs medicine injury and water source of technology owing to medication is inaccurate; make the ill back of fishes and shrimps be difficult to treatment, even cause the food safety crisis because body has resistance.

Chinese patent CN 1183045C discloses a kind of " multifunction sea-water purifying device and treatment process ", its structure is: this refining plant inside is provided with polylith water purification cloth, though this structure can purify sea water filter, but do not have disinfection, can't guarantee the normal growth of fry during with its culturing fish and shrimp.

Chinese patent ZL 98237421.6 discloses a kind of " photoelectric source sea-water purifying device ", just seawater is played the filtration, purification effect though it is easy to use, not to the seawater disinfection, water after the purification can not reach the best fishes and shrimps seedling water state of bringing up, and complex structure, use when being unfavorable for growing seedlings.

Summary of the invention

Goal of the invention of the present utility model is to solve the problem that prior art exists, a kind of filtration, purification sterilizing layer that multilayer utilization magnetization and herbal medicine are made that is provided with in filter-sterilizer is provided, not only with seawater cleaning but also with the water sterilization that purifies, the seawater that purifies after sterilizing is beneficial to the sea-water purifying device that the fishes and shrimps seedling is grown.

The purpose of this utility model is achieved in that a kind of sea-water purifying device, comprise the purification bucket, cross filter core, blowdown reducing valve, it also comprises a filter-sterilizer that is positioned at purification bucket below, and this filter-sterilizer inside is provided with bed filtration and purifies sterilizing layer, and a side is provided with water outlet.

Adopt technique scheme, compared with prior art, the beneficial effects of the utility model are:

1. through the filtering seawater of this strainer, limpid, pure.The optimization of water-quality guideline is obvious, mainly show the variation aspect of chemical oxygen consumption (COD) and two important physical and chemical indexs of dissolved oxygen (DO), our experiments show that: the sea water COD that the non-sterile device is handled is 15.4mg/L, reach 9.6mg/L after the filtration, DO rises to 8.7mg/L by original 7.6mg/L, has reached best water for larval nursing state.

2. improve egg hatching rate and rupture of membranes rate: ovum set-off thing is very serious in the ovum rupture of membranes process of seawater seed rearing.Reason mainly is a water quality inferiority, and how suitable bacterium breeds suspended substance in a short time in a large number, and thread fungus, bunching worm etc. are a large amount of parasitic, have a strong impact on ovum embryo's normal development, and the rupture of membranes rate is low to making, even dead midway.Use the seawater after this strainer filters, at lefteye flounder, globe fish ovum rupture of membranes, especially in 7 of the filefish hatch fish roe days, without any the set-off sign.And quantity of exchanged water has been reduced to 2-3 time/day by original 8 times/day, and fully no longer uses antibiosis and usually suppress bacterial reproduction.Greatly reduce production cost and labour intensity.Hatching rate and rupture of membranes rate have been improved.Do not using before this sterilizer, the filefish ovum is put into hatching barrel and is just overgrowed with thread fungus after three days on the ovum, though it is also not obvious to use antibiotic prevention effect.The rupture of membranes rate is generally about 25%-40%.Continuous 2 years rupture of membranes rates are all more than 85%-95% after using this strainer.

3. the fry speed of growth improves: with common seawater seed rearing fry vegetative period be 60 days, general requirements reaches 4-6cm, the specification gap is big.After the application, in same 60 days vegetative period, the fry specification has reached 7-8cm, and specification is also very neat.By contrast, cultivate fry with the seawater after the utility model processing, its speed of growth obviously improves.

4. ovum residual medicine on the fish body that can effectively prevent the globe fish treated with medicaments is grown along with the growth of fish, has avoided the secondary pollution of seawater, guarantees people's edible flesh safety.
