Abstract

The invention discloses a nano aluminum oxide water-purifying agent and a preparation method thereof. The nano aluminum oxide water-purifying agent is made from the following materials according to parts by weight: 2-6 parts of nano aluminum oxide, 20-40 parts of medical stone, 5-15 parts of celestite, 25-40 parts of zeolite, 10-25 parts of perlite, and 20-40 parts of wood charcoal. The nano aluminum oxide water-purifying agent has high adsorbing capacity, can adsorb toxic harmful substances in water, such as heavy metal, remove peculiar odor in water and reduce the content of harmful substances in water, and can release various minerals and trace elements good for the growth of fry while purifying water since the materials are rich in minerals, thus helping the fry to grow healthily and quickly.

Description

technical field [0001] The invention belongs to the field of water treatment, and in particular relates to a nano-alumina water purifying agent and a preparation method thereof. Background technique [0002] Since modern times, with the continuous increase of people's production activities, more and more various kinds of sewage are produced, the water pollution situation is getting more and more serious, and the heavy metal content in water often exceeds the standard. At present, in aquaculture ponds, it is necessary to purify the water in the original pond before putting in new fish fry, so as to remove some harmful substances such as heavy metals and create a suitable water environment. However, the current water body purification treatment has the effect It is relatively poor and cannot effectively remove heavy metals in water. Contents of the invention [0003] In order to make up for the deficiencies in the prior art, the present invention provides a nano-alumina wa...
