Abstract
The invention discloses an ultrafiltration purification method for industrialized seedling production water of macrobrachium rosenbergii. The method comprises five steps of primary precipitation, artificial seawater preparation and dark precipitation, physical filtration, membrane separation and ozone sterilization. The method is capable of removing all suspended particles and unicellular algae having the diameter above 0.1 micron in aquaculture water so that the water transparency is above 2 meters and the ammonium-nitrogen removal rate is above 90%, and the treated water is suitable for fry rearing of rare fish and shrimp; and due to ultrafiltration membrane separation in combination with secondary ozone sterilization, more than 99% of microorganisms (the diameter of common microorganisms is above 0.3 micron), and therefore, the transverse route of transmission of harmful microorganisms in the external environment is effectively cut off and stable production of the fry of fish and shrimp is guaranteed.
Description
Technical field
The present invention relates to water purification technology field, in particular a kind of Macrobrachium rosenbergii industrial seedling rearing water quality super-filtration purifying method.
Background technology
In recent years, grow seedlings water quality and the microorganism that cause due to coastal waters red tide, wawter bloom, the pollution of river exceed standard and cause that industrial seedling rearing unsuccessfully happens occasionally.Since 2010, the novel young disease outbreak of Macrobrachium rosenbergii that breaks out to Beijing University's area from south of the whole nation causes national Macrobrachium rosenbergii breeding output to reduce more than 2/3, raiser without seedling can support, market fluctuation is huge.Wherein one of major reason is exactly to propagate cause of disease by water source, river course and cause due to group disease outbreak due to intensive nursery.Therefore water source treatment technology becomes one of key factor of industrial seedling rearing success or failure.The mode of tradition water technology application sand filtration purification and chemical reagent killing microorganisms (as chlorination preparation sterilizing), one side traditional method effects of purification quality is poor and Germicidal Efficacy is unsatisfactory, chlorination can produce more halogenated hydrocarbon compound on the other hand, the content of these chlorinated organics is multiplied, and is to cause that the mankind suffer from the maximum root of various gastrointestinal cancer.
Summary of the invention
Technical problem to be solved by this invention is the problem existing in water treatment for prior art, and a kind of Macrobrachium rosenbergii industrial seedling rearing water quality super-filtration purifying method is provided.
Technical scheme of the present invention is as follows:

Behind obscure shallow lake, water is passed through to quartz filter 1, quartz filter 2 and accurate filter (cartridge filter) successively with pump, filter through three level physicals, small silt and throw out in water are further held back, again reduce the SDI value in water, make SDI value in water outlet reach the water inlet requirement of ultrafiltration system;
(4) membrane sepn
After three level physicals filter, water enters ultra-filtration membrane separation system, and ultra-filtration membrane separation system is made up of membrane element, pneumatic operation valve group, a complete set of equipment stored program controlled;
(5) ozone sterilization
Install ejector additional at system external supplying pipe, access ozonizer (YH-X-60P) carries out secondary degerming to water after treatment in (4).
Described elementary pond is soil property pond, and area is 5～10 mu, and 2～3 recycle.
Described dark settling tank is cement pit or Tu Chi, and size is 800～1000 cubic metres, utilizes canvas to make full shading treatment.
Described quartz filter 1 and quartz filter 2 are Φ 2800 × 3800mm carbon steel tank, inside establish that hanging basket water distribution, lower porous plate catchment, hand-hole, spigot discharge, venting hole, sight glass, spread respectively from top to bottom tri-layers of purity quartzite of high 1#2#3#.
Described accurate filter, containing φ 700 × 1000mm50 core 5um filter core composition, is in order to prevent that prime pre-treatment from can enter hyperfiltration membrane assembly by permeable fine-powder.
Ultra-filtration membrane: configuration ultrafiltration membrane elements is 32 6 " ultrafiltration membrane elements, main technical details: 1) design water production rate: 50.0m3/h; 2) produce water water quality: SDI≤2; 3) service temperature :≤40 DEG C; 4) design pressure :≤0.3MPa.
Cleaning system: by comprising that 1 of scavenging pump, 1 subassembly of cleaning water tank are formed in ultra-filtration equipment and use certain hour caudacoria surface can be subject to pollution or fouling to a certain extent.Utilize cleaning system to prepare relative clean-out system, can carry out matting to ultra-filtration membrane, make ultrafiltration system substantially recover its processing capacity.
Electrical apparatus control system: automatic control part adopts PLC central controlled mode, point full automatic control mode and manually control two kinds of working ordeies, can carry out operation and management comparatively easily, meets process water and provides safeguard for producing.Each topworks (pump) all establishes hand push button on housing, guarantees water station normal water supply while facilitating debugging, maintenance and automatic fault.
Beneficial effect of the present invention is: 1) cultivation water source is after this treatment system is processed, can remove 0.1 micron of above all suspended particles and unit cell algae of diameter, water transparency reaches more than 2 meters, ammonia nitrogen removal frank reaches more than 90%, and after processing, water quality is suitable for famous and precious fishes and shrimps seed breeding use; 2) through ultra-filtration membrane separate add secondary ozone sterilization can remove 99% with microorganism (general microorganism diameter more than 0.3 micron), effectively block harmful microbe horizontal transmission approach in external environment, ensured the stably manufactured that fishes and shrimps are grown seedlings.
