Abstract

The present invention provides an ecological purification material for aquaculture, which has a manufacturing method that one or two kinds of rice hulls, maltose and peanut shells are selected as materials; the materials are orderly soaked in a water glass solution, drained, heated and baked till the specified water content is achieved so as to obtain finished products. After the purification material is broadcast to cultivation water bodies, the beneficial ecological maintenance of the water bodies can be kept more than 13 months. The water bodies can be continuously purified, and cultivation objects can not fall sick.

Description

The ecological water-purifying material of used for aquiculture

Technical field

The invention belongs to the aquaculture technical field, provide a kind of and be dispensed onto in the water body, the ecological water-purifying material of the used for aquiculture of energy long-term role.

Technical background

A pollution that important technological problems is exactly a water body of aquaculture, because the feed that input Chi Zhonger is not eaten, the movement of material culture all become ever-increasing new pollutent and water body are run down, what worsen mainly shows as water hypoxia and the accumulation of objectionable impurities in water, acquire a certain degree and to cause the material culture morbidity, even dead, bring about great losses.Many investigators provide improvement or improvement technology, wherein there is utilization in water body, to spread fertilizer over the fields or increases material with certain effect or material and the water purifying technology, as Chinese patent " CN1430896 used for aquiculture antiseptic composition and application thereof " to provide a kind of be major ingredient by potassium ferrate or Na2Fe04, the composition that cooperates vehicle, stablizer, tackiness agent, lubricant to form, has the water oxygen of increasing gas concentration, the effect of removing heavy metal and harmful suspended matter; " process for fixation of CN1340613 bacteria to biologically repair culture environment of aquatic products " is with fixing of zeolite carrier, functional bacteria and zeolite are mixed and made into solid phase prod, render to water and culture in the pond, make it be sunken at the bottom of the pond and functional bacteria is bred fast, thereby make water body obtain repairing; Comprise oxygenate, solidifying agent, stablizer in the water purification agent that " CN1039520 oxygen supplying and water clarifying agent for aquatic culture " provides, produce oxygen after water-soluble, easy to use.

Prior art all obtains certain progress at aspects such as the chemical oxygen release agent of interpolation, beneficial microorganism, sterilizing agent, antiviral agents in water body, but also exist not enough, be mainly: 1, the material that chemical action is arranged of Tian Jiaing makes its mission that is through with after having discharged effective ingredient, can only play the limited effect of short period of time to water body, need constantly to add, and sometimes material culture is had side effects; 2, the beneficial microorganism of Tian Jiaing can not have survival for a long time in water bottom, and the change of envrionment conditions can influence their growth and decline, produces secondary pollution sometimes; 3, general disinfectant is again often original useful microorganism killing, and original useful ecology is destroyed.

Summary of the invention

Based on above understanding, the purpose of this invention is to provide a kind of promoter action of having kept to water ecology, and can improve the ecological purification material of the distribution of dissolved oxygen in the water body, this material possesses the surface that makes the beneficial microorganism apposition growth is arranged, and its density is moderate, can be when water body be subjected to mild agitation in water locomotory movement, make microorganism in water body, obtain useful diffusion, and, certain ability in conjunction with oxygen also must be arranged, to increase dissolved oxygen.

For achieving the above object, the technique means that the present invention takes is that one or both combinations in the rice husk that selection density is lower, wheat bran, the Pericarppium arachidis hypogaeae are handled with the stablizer water glass solution as basic material.Treatment process is: be mixed with the water glass solution that contains Na2SiO3 10%～70% earlier, the basic material that chooses not in wherein soaking, soak time is 1～10 hour, pull out, drain well, put and be heated to 100～120 degrees centigrade in warm air or the heating container, treat that water content reduced at 3%～9% o'clock, cool off finished product, the gained water-purifying material evenly is dispensed onto in the water body according to the scope of the every square of water surface 0.1～10Kg, can keep the optimum ecology of water body to hold time and reach 13 months, this has just guaranteed that water body is effectively purified in a culture-cycle.

Embodiment

Below be one embodiment of the present of invention

At first prepare Na2SiO3 concentration and be 30% water glass solution, get rice husk then, soaked wherein 3 hours, pull out, drain away the water, with 105 degrees centigrade of warm air beating, to water content be 7%, cool but finished product, be dispensed onto in the water body of culturing crucian, in a culture-cycle (10 months) by the consumption of every square metre of 4Kg, not seeing has any disease and raises the nose above water to breathe the phenomenon generation, water quality is ordorless, and contrast pond morbidity twice, rate ratio experiment low 20%.

Claims

1, the ecological water-purifying material of a kind of used for aquiculture is characterized in that, described material is by in basic material rice husk, wheat bran, the Pericarppium arachidis hypogaeae one or both, through soaking in water glass solution, pulls out and drains, and the technology handled of heating, drying is made then.

2, the ecological water-purifying material of used for aquiculture as claimed in claim 1 respectively has the range of choice of related parameter to be: Na in the water glass solution in its manufacture craft ₂SiO ₃Concentration is 10%～70%, and the soak time of basic material is 1～10 hour, and Heating temperature is 100～120 degrees centigrade, and heating back water content permissible value is 3%～9%.

3, water-purifying material as claimed in claim 1 or 2 is characterized in that its consumption that spreads fertilizer over the fields in the water body is every cubic metre of water body 0.1Kg～20Kg.

4, water-purifying material as claimed in claim 1 or 2 is characterized in that its a kind of concrete embodiment is: preparation Na ₂SiO ₃The water glass solution of concentration 30%, soak time 3 hours, 105 degrees centigrade of Heating temperatures, finished product water content are 7%, the amount of application of this water-purifying material is every square metre of water surface 4Kg.
