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, the nursery water quality caused due to coastal waters red tide, wawter bloom, the pollution of river and microorganism exceed standard and cause industrial seedling rearing unsuccessfully to happen occasionally.Since 2010, the Macrobrachium rosenbergii novel young disease outbreak that the whole nation is broken out from south to Beijing University's area causes national Macrobrachium rosenbergii breeding output to reduce more than 2/3, and raiser can support without seedling, market fluctuation is huge.Wherein one of major reason is exactly because intensive nursery to be spread disease former causing caused by group disease outbreak by water source, river course.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 the maximum root causing the mankind to suffer from various gastrointestinal cancer.
Summary of the invention
Technical problem to be solved by this invention is for prior art Problems existing in water treatment, provides a kind of Macrobrachium rosenbergii industrial seedling rearing water quality super-filtration purifying method.
Technical scheme of the present invention is as follows:
A kind of Macrobrachium rosenbergii industrial seedling rearing water quality super-filtration purifying method, its step is as follows:
(1) primary precipitation
Outer river is introduced primary precipitation pond, and every mu of 100kg quicklime slurrying is splashed, and in 2 ~ 3 days water bodys, mud suspended particle will be precipitated at the bottom of the pool with lime white, primary precipitation 15 ~ 25d;
(2) artificial seawater preparation and obscure shallow lake
When the outer river PH of primary precipitation is down to below 9.0, water is evacuated to dark settling tank (greenhouse tank, lucifuge), fresh water in dark settling tank is mixed with artificial seawater, its formula is as shown in the table, and precipitate 10 ~ 15 hours, in water, Micro Algae is lowered at the bottom of pond at no light condition; Process fresh water is then without the need to artificial seawater preparation link;

(3) physical filtering
Behind obscure shallow lake, with pump by water successively through quartz filter 1, quartz filter 2 and accurate filter (cartridge filter), filter through three level physicals, small silt and throw out in water are retained further, again reduce the SDI value in water, make the SDI value in water outlet reach the inflow requirement of ultrafiltration system;
(4) membrane sepn
After three level physicals filter, water enters Ultra filtration membrane system, and Ultra filtration membrane 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, it is degerming that access ozonizer (YH-X-60P) carries out secondary to the water after process 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 hanging basket water distribution, lower porous plate catchments, hand-hole, spigot discharge, venting hole, sight glass, spread high 1#2#3# tri-layers of purity quartzite from top to bottom respectively.
Described accurate filter, containing φ 700 × 1000mm50 core 5um filter core composition, is to prevent 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) water water quality is produced: SDI≤2; 3) service temperature :≤40 DEG C; 4) design pressure :≤0.3MPa.
Cleaning system: by comprising scavenging pump 1, cleaning water tank 1 subassembly is formed in ultra-filtration equipment and uses certain hour caudacoria surface can by pollution to a certain extent or fouling.Utilize cleaning system to prepare relative clean-out system, matting can be carried out 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 Non-follow control two kinds of working ordeies, can carry out operation and management comparatively easily, meets process water provide safeguard for producing.Each topworks (pump) all establishes hand push button on housing, convenient debugging, maintenance and automatic fault time guarantee water station normal water supply.
Beneficial effect of the present invention is: 1) cultivate water source after the process of present treatment system, all suspended particles and the unit cell algae of diameter more than 0.1 micron can be removed, water transparency reaches more than 2 meters, ammonia nitrogen removal frank reaches more than 90%, and after process, water quality is suitable for the use of famous and precious fishes and shrimps seed breeding; 2) through Ultra filtration membrane add secondary ozone sterilization can remove 99% with microorganism (general microorganism diameter is more than 0.3 micron), effectively block harmful microbe horizontal transmission approach in external environment, ensure the stably manufactured of fishes and shrimps nursery.
