Abstract

The invention discloses an attapulgite oil de-coloring agent for water treatment. The attapulgite oil de-coloring agent is prepared from the following raw materials in parts by weight: 35 to 50 parts of high-viscosity attapulgite clay, 7 to 15 parts of active carbon, 6 to 12 parts of a toughening agent, 0.1 to 1.5 parts of sodium hypochlorite, 9 to 18 parts of carclazyte, 6 to 8 parts of a curing agent, 7 to 15 parts of adsorption resin, 10 to 14 parts of an anti-foaming agent and 8 to 15 parts of dicyandiamide formaldehyde resin. A preparation method of the attapulgite oil de-coloring agent for the water treatment mainly comprises the following steps: crushing, acidifying, washing, drying and grinding. The attapulgite oil de-coloring agent for the water treatment, provided by the invention, has the advantages of less use amount, short sedimentation time, good de-coloring effect and the like. The preparation method provided by the invention is simple and feasible and relatively low in cost and does not generate objects which cause pollution to the environment.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to an attapulgite oil product decolorizer for water treatment and a preparation method thereof. Background technique [0002] The processed attapulgite clay products are ideal adsorbents, food processing aids and food additives, which can replace activated carbon. It can not only decolorize, but also deodorize and deodorize, remove heavy metal ions and carcinogens, and has certain selectivity, which provides convenience for production. It can be used as refrigerator deodorant, sewage treatment agent, household water purifier , Oil refining and decolorizing agent, the effect is extremely obvious, it can be used as filler, carrier, additive and binder of medicine in medicine. Using attapulgite clay to decolorize liquid glucose can reduce the twelve processes of purification by powder activated carbon to ten processes, and shorten the process cycle by 50 minutes, which is very benefici...
