Description

A kind of preparation method for the fishing purse seine for handling breeding pollution
Technical field
The present invention relates to a kind of preparation method for the fishing purse seine for handling breeding pollution, belong to technical field of aquaculture.
Background technology
To encourage the development of cultivation fishery, country adjusts Fisheries Development policy energetically, using aquaculture as national fishery The emphasis of development.Seining cultivation is not only to improve the important measures of lake output of aquatic products, or the main source of fishery economic. With greatly developing for seining cultivation industry, national aquaculture yield cumulative year after year, particularly nearly ten years, speedup are accelerated, But while people's aquatic products demand is met, extremely serious destruction is also brought to water environment, or even threatens lake life The balance of state system, seriously constrain the sustainable development of enclosure culture in lake industry.
Lake is the Main Waters resource of culture fishery, and necessary material base is provided for the development of seining cultivation industry Condition.But culture fishery the problem of some are inevitable has been met with while fast development, most serious is exactly water body Environment is heavily polluted, and destroys the rapport between water environment and aquaculture, and this seining cultivation industry made is faced with resource With the huge challenge of the dual restriction of environment.
Artificial bait throwing in is the important measures that enclosure culture in lake quickly improves output of aquatic products, but the bait fed is usual Have more than 30% not by fish.The bait not utilized sink under water after by microorganism decomposition consume dissolved oxygen, and then discharge The nutrients such as nitrogen, phosphorus, fertilizer is turned into by material circulation, polluted-water environment, changes lake water water quality.So daily ration, feeding quantity Be continuously increased be accelerate lake eutrophication, cause lake water quality deteriorate principal element.
The aquatic animal of seining cultivation can produce a large amount of excretas and secretion, contain substantial amounts of nitrification in these materials Thing, such as：Ammonia, urea, creatine, protein etc..According to investigations, often production 1kg fish approximately produce 162g or so excrement it is organic Thing, mainly include 30g total nitrogens, 7g total phosphorus.A large amount of residual feed and excretas are deposited on lakebed with secretion, pass through the decomposition of microorganism Act on, the nutrient such as nitrogen, phosphorus in releasing organics, cause lake water overnutrition to cause body eutrophication, and then pollute Water quality.
Therefore, how to mitigate the pressure of Water Environment In Lakes, be effectively improved the capacity of self-regulation of water environment, be to realize life The grand strategy measure of state fishery.
The content of the invention
The technical problems to be solved by the invention：For a large amount of residual feed and excretas and secretion in current seining cultivation industry Lakebed is deposited on, by the decomposition of microorganism, the nutrient such as nitrogen, phosphorus in releasing organics, causes lake water nutrition It is surplus to cause body eutrophication, and then the problem of polluted water, there is provided a kind of preparation for the fishing purse seine for handling breeding pollution Method.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of preparation method for the fishing purse seine for handling breeding pollution, it is characterised in that concretely comprise the following steps：
（1）Natural zeolite is taken to be well mixed after crushing sieving with lanthanum chloride addition deionized water, pH is to 10~11 for regulation, and stirs 2~3h is staticly settled after mixing 1~2h, filters to obtain filter residue, filter residue washing and drying is obtained into composite；
（2）Take ultra-high molecular weight polyethylene to be fitted into melting extrusion in extruder after being mixed with composite, obtain melt；
（3）The melt of extrusion is cooled down and three-level stretching is carried out in the presence of carry-over pinch rolls, it is stretched to a diameter of 0.5~ 1.2mm monofilament, obtains composite monofilament；
（4）Composite monofilament is placed on knot netting machine and is made into the purse seine that mesh is 10~50mm, the fishing that must handle breeding pollution is used Purse seine.
Step（1）The mass ratio of the natural zeolite and lanthanum chloride is 5:1.
Step（2）The mass ratio of the ultra-high molecular weight polyethylene and composite is 20:1.
Step（2）The melting extrusion temperature is that preheating zone temperature is set to 120~130 DEG C, Heating Zone Temperature is set to 130~ 140 DEG C, melting zone temperature is 135~145 DEG C, and transition region temperature is set to 130~140 DEG C, metering Pen Ji areas temperature is 130~ 140℃。
Step（3）The three-level extensograph parameter is that one-level draft temperature is 80~90 DEG C, and draw ratio is 15~20, two level Stretch draft temperature be 90~100 DEG C, draw ratio be 2~5, three-level draft temperature be 100~110 DEG C, draw ratio be 1~ 2。
Step（2）The ultra-high molecular weight polyethylene is the ultra-high molecular weight polyethylene of molecular weight 150~1,800,000.
Compared with other method, advantageous effects are the present invention：
Zeolite is the porous aluminosilicate crystals in skeletal structure, possesses higher cation exchange capacity (CEC), present invention profit The ammonia nitrogen gone with the cation exchange capacity (CEC) of zeolite in water removal, and lanthanum hydroxide sediment is loaded to by day using liquid-phase precipitation method Right zeolite surface, prepare lanthanum hydroxide-natural zeolite composite, by the oh group and P elements on lanthanum hydroxide surface it Between ligand exchange, adsorb P elements, effectively remove the nutrient such as excessive nitrogen, phosphorus in water body, mitigate Water Environment In Lakes Pressure, be effectively improved the capacity of self-regulation of water environment, be worth of widely use.
