Problems solved by technology

In the process of aquaculture, the one-sided pursuit of high yield often leads to a series of aquaculture problems such as turbidity and suspension of impurities in the water body, reduced water transparency, and insufficient dissolved oxygen due to excessive increase in water body nutrition, excessive feeding, fertilization, and high-density stocking. Directly or indirectly harm the farmed animals in the water body, causing economic losses

preparation example Construction

[0031] The present invention also provides a kind of preparation method of water quality improving agent, comprises the following steps:

[0032]Take aluminum sulfate, sodium phate, sodium metasilicate, zeolite powder and adsorbent, and mix 30 to 45 parts of aluminum sulfate, 5 to 10 parts of sodium humate, and 5 to 10 parts of sodium metasilicate in parts by weight. 20-30 parts of zeolite powder and 5-40 parts of adsorbent. Mix the above components uniformly to obtain the water quality improver.

[0033] Specifically, under dry conditions, 30-45 parts by weight of aluminum sulfate, 5-10 parts of sodium humate, 5-10 parts of sodium metasilicate, 20-30 parts of zeolite powder and 5-40 parts of adsorbent Add it to the reaction kettle at one time, stir and mix evenly under the condition of 5°C-45°C to obtain a water quality improver, and stir at a stirring speed of 40-80 revolutions per minute for 20-40 minutes and mix evenly. For reaction temperature, generally get final produc...

Embodiment 1

[0037] A water quality improver comprises the following components in parts by weight: 30 parts of aluminum potassium sulfate, 5 parts of sodium humate, 5 parts of sodium metasilicate, 20 parts of zeolite powder, 20 parts of activated carbon and 20 parts of bentonite.

[0038] The water quality improver of the present embodiment, its preparation method is as follows:

[0039] Under dry conditions, add 30 parts by weight of aluminum potassium sulfate, 5 parts of sodium humate, 5 parts of sodium metasilicate, 20 parts of zeolite powder, 20 parts of activated carbon and 20 parts of bentonite into the reaction kettle at one time. Under the conditions, the mixture was stirred for 40 minutes at a stirring speed of 40 rpm to obtain a water quality improver.

Abstract

The invention provides a water quality improver and a preparation method thereof. The water quality improver comprises the following components calculated in parts by weight: 30-45 parts of aluminum sulfate salt, 5-10 parts of sodium humate, 5-10 parts of sodium metasilicate, 20-30 parts of zeolite powder and 5-40 parts of an adsorbent. The water quality improver provided by the invention has thebenefits that the aluminum sulfate salt stabilizes and aggregates colloids into micro-flocs under the action of condensation, and then flocculates with other adsorbents (such as modified activated carbon, activated carbon, and clinoptilolite powder) to form micro-flocs and grows into larger flocs through adsorption, winding and bridging effects, so that the transparency of the aquaculture water isincreased, the water is clear, the growth and the reproduction of alga are facilitated, and more oxygen and baits are provided for farmed animals; the content of ammonia nitrogen and nitrite are reduced, the dissolved oxygen is increased, and the purpose of increasing the production is achieved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a water quality improver and a preparation method thereof. Background technique [0002] my country is a big aquaculture country with a long history of aquaculture. With the continuous improvement of the economic and technological level, people's demand for aquaculture animals and quality is also constantly improving, and the aquaculture industry is showing a rapid development trend. Aquaculture is mainly based on the traditional high-density, multi-species, large-scale fertilization and feeding and other farming models. In the process of aquaculture, the one-sided pursuit of high yield often leads to a series of aquaculture problems such as turbidity and suspension of impurities in the water body, reduced water transparency, and insufficient dissolved oxygen due to excessive increase in water body nutrition, excessive feeding, fertilization, and high-density stocking. Dire...
