Description
Technical Field
The invention belongs to the field of aquaculture, and particularly relates to a water quality regulating agent for industrial aquaculture and a production method thereof.
Background
The cultivation of fish, shrimp, crab and ginseng makes outstanding contribution to ensuring the supply of high-quality animal protein for urban and rural residents, reducing the utilization strength of aquatic organism resources in natural water areas, protecting the ecological environment and the like.
In general, water can be decomposed and transformed by self-cleaning ability (i.e. natural physical, chemical and biological effects), reducing and eliminating pollutants, and maintaining normal fishery functions. In the culture process, particularly under the condition of high-density culture, harmful pollutants are continuously generated and accumulated, the pollution speed is often far higher than the self-purification capacity of a water body, so that the content of pollutants such as ammonia nitrogen, nitrite, phosphate, sulfide, organic matters and the like is seriously exceeded, and the normal growth of cultured organisms is finally influenced. In addition, the deterioration of the quality of the aquaculture water can cause diseases. In order to control the occurrence of diseases, breeding personnel and enterprises generally rely on antibiotics and other bactericidal drugs, so that the cost is increased, and the quality of aquatic products is greatly damaged due to the residue problem. Therefore, the quality control of the aquaculture water body has very important significance for production.
At present, three approaches of a physical method, a chemical method and a biological method are mainly used for purifying, regulating and controlling the water body of the industrial aquaculture. The physical method is to improve water quality by adopting the modes of adsorption, precipitation, filtration, dilution and the like, and mainly comprises water exchange, additional humic acid, zeolite and the like. The former is characterized by simple and easy operation, but large water consumption, and the changed tail water causes pollution pressure to the relevant environment; the latter is characterized by a relative saving in water, but at a higher cost. The chemical method is mainly characterized in that a proper amount of chemical substances (such as quick lime, potassium permanganate, hydrogen peroxide, sodium percarbonate, calcium peroxide, bleaching powder, sodium hypochlorite, trichloroisocyanuric acid, bromohydantoin, bromochlorohydantoin and the like) are added into a water body, and target pollutants are removed or changed through reaction. Its advantages are high effect, low cost and easy generation of secondary pollution. Biological methods mostly refer to the treatment of water quality by using microecologics or biofilms prepared from single or compound beneficial bacteria. At present, the most widely applied to aquaculture are photosynthetic bacteria, chemoheterotrophic bacteria, nitrobacteria, bacillus, saccharomycetes, lactic acid bacteria and the like. The beneficial bacteria play a role in substance circulation and energy circulation by absorbing and converting toxic and harmful substances such as ammonia nitrogen, nitrite nitrogen, phosphate, sulfide and the like in the water body. The biological method has the advantages of small side effect, but has the problems of slow effect and unstable effect (greatly influenced by factors such as temperature).
Disclosure of Invention
The invention aims to provide a special water quality regulating agent for industrial aquaculture and a production method thereof, and the water quality regulating agent has the advantages of quick response, environmental friendliness and low cost.
The invention is realized by the following technical scheme:
a special water quality regulating agent for industrial aquaculture comprises the following components in parts by weight: white mud: 50-95%, silicate: 0-30%, rare earth: 0-5%, volcanic ash: 0-30%, baking soda: 0 to 20 percent.
The invention also provides a production method of the water quality regulating agent, which comprises the following steps:
1) adding water into white mud which is a byproduct in the production of soda by an ammonia-soda process to stir to form slurry;
2) screening white mud particles with the particle size of below 100 microns by using a vibrating screen;
3) adding a dimethyl silicone oil surface modifier and a sodium hexametaphosphate dispersant into white mud slurry with the particle size of less than 100 mu m to form mixed slurry;
4) carrying out superfine grinding on the mixed slurry obtained in the step 3) to prepare nano-micron mixed slurry;
5) dehydrating the nano-micron mixed slurry obtained in the step 4) through filter pressing to prepare a filter cake;
6) and adding the silicate, the rare earth, the volcanic ash and the baking soda into the filter cake according to the proportion, and uniformly stirring to obtain a finished product.
Further, the added dimethyl silicone oil surface modifier and the sodium hexametaphosphate dispersant are respectively 0.1 percent and 0.2 percent of the total mass of the water quality regulator.
Compared with the prior art, the invention has the beneficial effects that:

Detailed Description
Example 1 a water quality control agent for industrial seawater shrimp culture and a method for producing the same, as shown in fig. 1, the specific steps are as follows:
step one, mixing 100kg of white mud which is a byproduct of soda production by an ammonia-soda process of Qingdao soda industry company with 55kg of water, and stirring for 30min by adopting a double-shaft stirrer (square and round brand, 5kw) to form flowable slurry;
step two, the slurry is sent into an electromagnetic vibrating screen (Haite brand, DZSF type, 1kw) through a slurry pump (Chengni brand, BW type, 5kw), and white mud particles with the particle size of less than 100 mu m are collected;
adding 200g of dimethyl silicone oil surface modifier and 300g of sodium hexametaphosphate dispersant into white mud particle slurry with the particle size of less than 100 mu m, and stirring in a stainless steel barrel to form mixed slurry;
grinding the mixed slurry for 2.5 hours by adopting a high-energy ball mill (Luguan brand, 3kw) to prepare nano-micron mixed slurry with the particle size less than 3 mu m;
step five, dehydrating the nano-micron mixed slurry by adopting a plate-and-frame filter press (Qingdao Borui product, model 5T/h, 1.75kw) to form a filter cake with the water content of 45-50%;
and step six, adding 5kg of sodium silicate (industrial purity), 10kg of baking soda (food grade) 20g of rare earth (industrial purity) and 2kg of volcanic ash (industrial purity) into 100kg of filter cake, and stirring in a stainless steel barrel for 30min to prepare the special water quality regulator for industrial prawn mariculture.
The water quality regulating agent prepared by the method is applied to industrial healthy culture of penaeus vannamei boone
Breeding background: 50m for each culture pond3A body of water; putting about 5 million shrimps with the body length of 8-10mm into each pond; the temperature of the seawater is 25-27 ℃; feeding 1 time per day; discharging sewage for 1 time (the discharged sewage accounts for about 10 percent of the volume of the total culture water body), and adding water to supplement the water level to the original water level.
1. Uniformly stirring 0.5kg of the water quality regulating agent prepared by the method and 4.5kg of seawater in a plastic barrel to form a use solution;
2. manually spraying the using liquid of the water quality regulator into the culture pond within 10min after feeding the penaeus vannamei culture pond every day;
3. and performing other operations necessary for the culture of the penaeus vannamei boone.
Note: the above is 50m each3The usage amount of the water body culture pond is 0.5kg each time, and after the prawn body grows more than 60mm, the usage amount of the water quality control agent is increased to 15g/m3Water body until harvest.
And (3) breeding results: comparative experiments carried out in the village on the Longshan street village in Shandong province, Haiyang city, Shandong province, from 6 months in 2019 to 8 months in 2019 show that: compared with a culture pond without the water quality control agent, the color of the penaeus vannamei boone in the experimental pond is smoother and brighter; the molting interval period is short, the molting is fast, and no soft shell is found; the average body length of 60 balances is about 15% longer than that of the control group, and the mortality rate is about 10% lower than that of the control group; no viscous dirt such as moss is seen at the bottom and the edge of the experimental group culture pond in the whole process.
Example 2 Water quality control agent special for sea cucumber industrial aquaculture and production method thereof
The first step to the fifth step are the same as the example 1;
step six, adding 3kg of sodium silicate (industrial purity), 1kg of baking soda (food grade) 20g of rare earth (industrial purity) and 1kg of volcanic ash (industrial purity) into 100kg of filter cake, and stirring in a stainless steel barrel for 30min to prepare the special water quality regulator for industrial sea cucumber cultivation.
The water quality regulator prepared by the method is used for industrial healthy cultivation of stichopus japonicus
Breeding background: each culture pond is 24m2Water surface, water depth 1.1 m; about 1000 ginseng seedlings with the weight of about 20g are placed in each pond; the temperature of the seawater is 15-22 ℃; feeding 1 time every 2 days, discharging 1 time (the discharge accounts for about 25% of the total culture water volume), and adding water to supplement the water level.
1. Uniformly stirring 0.3kg of water quality regulating agent and 3.0kg of seawater in a plastic barrel to form a use solution;
2. and manually spraying the using liquid of the water quality regulator into the culture pond within 10min after feeding the stichopus japonicus culture pond every 2 days.
Note: the above is each 24m2The using amount of the culture pond on the water surface is 0.3kg each time.
As a result: comparative experiments carried out in the village on the Longshan street village of the Shandong province, Haiyang city, 2019, between 3 months and 2019, show that: compared with a culture pond without using a special water quality control agent, the stichopus japonicus in the experimental pond has smoother and brighter body color; diseases such as mouth swelling, intestine vomiting, skin dissolving, head shaking, stiffness and the like are not found; the growth rate is high, and the body weight is increased by 16.9 percent compared with the control pool on average.
