Purpose of water-quality purifying agent containing biological enzymes

Abstract

The invention discloses a purpose of a water-quality purifying agent containing biological enzymes, and particularly relates to the purpose of the water-quality purifying agent containing biological enzymes for polluted water quality purification. The water-quality purifying agent is prepared from the following ingredients in parts by weight: 20 to 25 parts of enzyme loading sorghum straw active carbon, 4 to 6 parts of sodium alginate, 6 to 8 parts of polyferric chloride, 3 to 7 parts of polyaluminium chloride, 30 to 35 parts of modified bentonite, 3 to 7 parts of polyacrylamide, 3 to 8 partsof plant fiber and 200 to 300 parts of distilled water. The purpose has the beneficial effects that all of the ingredients in the water-quality purifying agent can achieve the cooperated effect; through physical and chemical adsorption, harmful substances such as nitrogen, phosphorus, organic matters and heavy metal ions in the sewage can be effectively eliminated, so that impurities, eutrophication substances and the like can be settled through flocculation; meanwhile, the relatively good surface performance is realized; the selective adsorption effect on the organic contaminants is good.

Description

Technical field [0001] The present invention relates to the field of water purification, in particular to the use of a water purification agent containing biological enzymes. technical background [0002] Currently commonly used water purifiers include the following categories: aluminum salts, such as polyaluminum chloride, hexahydrate aluminum trichloride, aluminum sulfate, etc.; iron salts: ferric chloride, etc.; high molecular polymers, such as polypropionyl ammonium, etc. ;diatomite. The first three water purifiers are expensive, and the presence of metal ions limits their scope of use. The iron salt in it has a sinking effect and has a good removal effect on mud-containing high-turbidity sewage, but it affects water quality and color. However, the use of diatomaceous earth as a water purifying agent has a lower price. Due to its resource constraints, it is late in development and is in its infancy. The existing diatomite water purifiers generally use the physical properties...

Problems solved by technology

The first three water purifiers are relatively expensive, and their scope of use is limited by the presence of metal ions. The iron salts in them act as sinks and are effective in removing muddy and high-turbidity sewage, but they affect the color of the water quality. , and the use of diatomite as a water purifier has a lower price. Because of resource constraints, the development is late and is in its infancy. The existing diatomite water purifiers generally use the physical properties of diatomite itself Purification of water quality, due to its slow flocculation speed and long suspension time, often the water purification effect is not good and cannot meet the requirements

A few use diatomite to supplement other additives, such as "Preparation and Application of Composite High-efficiency Water Purifier", which mainly use diatomite as raw material, activate diatomite powder, polyaluminum chloride, polysulfuric acid Iron, polyaluminum sulfate or polyaluminum chloride, and boron-magnesium tailing slag modified substances have made some progress in water purifiers that only use diatomite, but because they are purified with the same formula for different water qualities, often The purification effect of certain water quality is good, but the purification effect of other different water quality is not good, it cannot meet the requirements of users, the adaptability is poor, and the purification effect is unstable
