Description
Technical field：
The present invention relates to treatment technology of effluent from aquaculture field, and in particular to a kind of fishes and shrimps water for larval nursing processing method and its dress
Put.
Background technology：
Raising fish and shrimp is economic worth cultivation project higher in aquaculture cultivation, its first since fishes and shrimps nursery,
And the water quality of breeding water is the key factor for influenceing the stage emergence rate.By river or seawater it is original in traditional breeding process
Water, uses after precipitation, sterilization directly as breeding water.But with river, the deterioration of seawater quality, ammonia nitrogen, Asia in water body
The harmful substances such as nitrate nitrogen occur or exceeded, pathogenic bacteria amount reproduction in water, and pathogenic bacteria not only consume the dissolved oxygen in water body, and
And easily causing the group disease outbreak of fishes and shrimps, precipitation and disinfecting process introduce substantial amounts of chemical drugs during traditional water treatment
Agent, causes a certain amount of chemical residual in cultivation water, so that cause the pollution of water body, while traditional handicraft process is not accounted for
To the supplement of dissolved oxygen in water body, existing high-density breeding is not utilized.Therefore, a kind of the treated of fishes and shrimps water for larval nursing is studied
Journey is most important.Chinese patent CN2014101888763 discloses a kind of Macrobrachium rosenbergii industrial seedling rearing water quality super-filtration purifying side
Method, sequentially passes through primary precipitation, artificial seawater and prepares and by precipitation, physical filtering, five steps of UF membrane and ozone sterilization, will
Bacterial virus removal in river, finally gives clarification water quality.The technique is by traditional breeding water processing procedure, Ultra filtration membrane
Process and ozone sterilization process are effectively processed breeding water, but ozone sterilizing process easily causes pathogenic bacteria
The resistance to the action of a drug, limit the long-term use of technique.
The content of the invention：
Present invention aim to overcome that the shortcoming that prior art is present, there is provided a kind of fishes and shrimps water for larval nursing processing method, solution
The existing water treatment process of having determined is complicated, content of oxygen dissolved in water is too low after treatment, existing chemical sterilizing process is easily led
The problems such as lacking the treatment to ammonia nitrogen and nitrite during the resistance to the action of a drug and handling process that cause pathogenic bacteria.
In order to solve the above problems, a kind of fishes and shrimps water for larval nursing processing method of the present invention specifically includes following step
Suddenly：
(1) silt, solid particulate matter in raw water being sequentially passed through into grid, cartridge filter retention raw water；
(2) it is then delivered in MBR devices, MBR devices are built-in, and membrane module uses antibiotic property anti-pollution doughnut
Milipore filter, is constantly aerated by aerator in MBR membrane cisternas, and the water in MBR membrane cisternas is pumped into product by external self priming pump
In water tank, processed by MBR devices, the clearance of Inactivation of Enteric Viruses In Water is 99.9%, and removal of bacteria rate is 99.99%, is dissolved in water
Oxygen is 3~6mg/L；
(3) detected to producing the water quality in water tank, regulating water quality pH and salinity meet the requirement of raising fish and shrimp.
Further, the antibiotic property anti-pollution hollow fiber ultrafiltration membrane is polyvinylidene fluoride (PVDF) ultrafiltration membrane, and the membrane material is not
But to the clearance of bacterium and virus more than 99.9%, while membrane material anti-microbial property is good, reduce after fouling membrane brings
Phase cleaning charge, while extending the service life of equipment.
A kind of fishes and shrimps water for larval nursing processing unit of the present invention, including raw water water tank, grid, elevator pump, ensured public security
Filter, built-in MBR devices, product water tank and on-Line Monitor Device, raw water water tank pass sequentially through grid and elevator pump and ensured public security
Filter water inlet is connected, and cartridge filter delivery port is connected with built-in MBR devices water inlet, and MBR devices delivery port is by certainly
Sucking pump is connected with water tank is produced, and is fixedly installed in online monitoring device real-time monitoring water on the pipeline that self priming pump is connected with product water tank
Dissolved oxygen, COD, ammonia nitrogen, the content of nitrite nitrogen.
The present invention compared with prior art, with advantages below：(1) in increased fishes and shrimps water for larval nursing by aerator
Dissolved oxygen amount；(2) MBR devices not only can effectively remove bacterium and the virus in water body, while to the ammonia nitrogen in water and organic
Thing has certain removal effect, and effluent quality fully meets the requirement of fishes and shrimps water for larval nursing；(3) making for chemical agent is avoided
With.
