Auxiliary agent for water treatment and its preparation method

Abstract

The water treatment auxiliary agent and the preparation method of the water treatment agent. At present, the chemical coagulation method is generally used in the field of water treatment at home and abroad, that is, inorganic salts such as aluminum salts and iron salts are used as water purifiers, and the hydrolysis and condensation reactions of iron ions and aluminum ions are used to purify water. The price of existing aluminum salt and iron salt water purifying agent is on the high side, which makes the cost of water treatment remain high. Water treatment aid, its composition comprises: calcium oxide, carboxymethyl cellulose, alginic acid, and its weight and number ratio is calcium oxide: carboxymethyl cellulose: alginic acid=20-80: 10-30: 10-50 . The product of the invention is used as a coagulant for water treatment.

Description

Technical field: [0001] The invention relates to a coagulation aid in water treatment and the application of the coagulation aid. Background technique: [0002] At present, the chemical coagulation method is generally used in the field of water treatment at home and abroad, that is, inorganic salts such as aluminum salts and iron salts are used as water purifiers, and the hydrolysis and condensation reactions of iron ions and aluminum ions are used to purify water. The price of existing aluminum salt and iron salt water purifying agent is on the high side, which makes the cost of water treatment remain high.
