Problems solved by technology

The eutrophication of the water body will cause the pH to drop, and the pH drop will not only lead to an increase in sulfide, but also to an increase in the activity of heavy metals, which leads to an increased risk of diseases such as bone pain
[0004] At present, most aquaculture farms and rivers that require water quality treatment are not connected to the sewage treatment network. When water pollution occurs, water circulation is used to delay the deterioration of the situation, but the effect of this method is not ideal
And if adding chemical agents to solve the odor and pollution, although there is a certain effect, most of the chemical agents are not compatible with aquatic organisms
However, physical control methods such as draining and re-irrigating are used to solve the problem of odor and pollution, which is costly, requires a lot of manpower and material resources, and affects normal use.

preparation example Construction

[0035] A preferred preparation process of the purifying agent includes: 1) Adding water into the reaction kettle, adding magnesium oxide while stirring, after fully reacting, when the temperature drops to 65-95°C, adding organic acid, and stirring (for example, 30 minutes); 2) Then add the suspending agent and stir (for example, 40 minutes); 3) After that, add the biological bacteria within 24 hours before use, and the final pH value of the purifier is 9.5-10.5.

[0036] In some specific and preferred embodiments, in terms of weight percentage, the raw material formula of the purifying agent includes magnesia 10-60%, organic acid 0.04-0.125%, suspending agent 0.0013-0.5%, and biological bacteria 0.001-0.5%, Others are water;

[0037] Further, the magnesium oxide raw material preferably has a purity ratio of magnesium oxide greater than 90%, and silicon dioxide lower than 0.5%. It should be noted that in actual production, there will inevitably be impurities in the magnesium o...

Embodiment 1

[0051] A purifying agent for deodorizing river course water, which is prepared by using the following raw materials in the following steps in terms of weight percentage: 1) adding water into a reaction kettle, adding magnesium oxide while stirring, and adding magnesium oxide for every 100 parts by weight of magnesium oxide Add 200 parts of water, and when the temperature drops to 70°C after full reaction, 2) Add 0.3 parts of organic acid (75% glacial acetic acid) and stir for 30 minutes; 3) Then add suspending agent (hydroxypropyl methylcellulose, viscosity specification 15,000 mPa.s) 2 parts, stirred for 40 minutes; 4) After adding 1 part of microbial bacteria (ammonia nitrogen degrading bacteria, organic phosphorus degrading bacteria), stirred for 5 minutes; the final concentration of the purifier was 56%, and the pH value was 9.6. The purification ability of the prepared purifying agent is tested:

Abstract

The invention discloses a purifying agent suitable for aquaculture and river deodorization and a preparation method and an application thereof. The purifying agent is a solid-liquid mixture, a pH is 9.5-10.5, and components thereof contain magnesium hydrate, organic acid, a suspending agent, biological bacteria and water, wherein mass content of the magnesium hydrate is 10-70%, the mass content ofthe suspending agent is 0.001-5%, the biological bacteria are eutrophic degrading bacteria, and the mass content thereof is 0.001-10%. The preparation method for the purifying agent comprises the following steps: enabling magnesium oxide to perform a hydration reaction with water and generating the magnesium hydrate, and adding the suspending agent and the biological bacteria while a temperatureis below 95 DEG C, uniformly mixing, to obtain the purifying agent. The purifying agent is particularly suitable for the aquaculture and the river deodorization, good in deodorization effect, convenient to operate, and good in safety.

Description

technical field [0001] The invention relates to the technical field of aquaculture and river courses, in particular to a purifying agent capable of deodorizing and purifying water in aquaculture and river courses and a preparation method thereof. Background technique [0002] With the development of the economy, the discharge of living and production sewage is increasing, which brings great pressure to the environment. Sewage pollution and excessive use of chemical fertilizers lead to heavy metal pollution, high nutrient loads and other problems, resulting in water quality that cannot be used for irrigation, aquaculture and pleasant enjoyment of the environment. Under extreme conditions, algal blooms can cause problems such as toxicity to organisms, reduced water production values, low dissolved oxygen, and low water clarity. [0003] In addition, the pH value in water quality is also an important pollution-related factor. The eutrophication of the water body will cause th...
