Embodiment 1

[0018] Prepare 1000kg of the present invention

[0019] (1) Weigh 120kg of tripolyphosphate and 250kg of EDTA (ethylenediaminetetraacetic acid) into a homogenizer or homogenizer and stir evenly;

[0020] (2) Put the uniformly stirred material into the heating equipment, and then add 410kg of sodium dodecylbenzenesulfonate to it to stir the material evenly; then, heat up and control the temperature at 75-80°C to react and solidify ;

[0021] (3) After the above solidified material is cooled, add 100kg of alkylaryl polyether alcohol and 120kg of protease, and crush it in a crushing device to make a solid powder product.

Embodiment 2

[0023] Prepare 2500kg of the present invention

[0024] (1) Weigh 500kg of sodium hexametaphosphate and 620kg of NTA (aminotriacetic acid) into a homogenizer or homogenizer and stir evenly;

[0025] (2) Put the uniformly stirred material into the heating equipment, and then add 805kg Tween 20 to it to stir the material evenly; then, heat up and control the temperature at 75-80°C to react and solidify;

[0026] (3) After the above solidified material is cooled, add 375kg of modified polyether and 200kg of KAC, and crush it in a crushing device to make a solid powder product.

Abstract

The invention discloses novel membrane cleaning agent, which is prepared by mixing the following components in percentage by weight: 10 to 25 percent of wetting agent, 10 to 20 percent of solubilizer, 20 to 35 percent of chelant, 35 to 55 percent of surfactant and 5 to 12 percent of bioactive enzyme, wherein the wetting agent may be tripolyphosphate or sodium hexametaphosphate; the solubilizer may be alkaryl polyether polyol or modified polyether; the chelant may be ethylene diamine tetraacetic acid, diethyltriamine pentaacetic acid or aminotriacetic acid; the surfactant may be sodium dodecyl benzene sulfonate or Tween 20; and the bioactive enzyme may be KAC or protease. The novel membrane cleaning agent can permeate dirt quickly and undergoes a chelation reaction, so the cleaning time is saved, the damage caused by the cleaning agent to the membrane surface is relieved, and the service life of the member is prolonged.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a filter membrane cleaning agent. Background technique [0002] With the development of industrialization, oily wastewater, heavy metal wastewater and other high-concentration, refractory, toxic and harmful industrial wastewater discharged from petroleum, steel, electroplating and other industries are increasing, which brings great hidden dangers to environmental safety. . Membrane separation technology is a relatively effective water treatment technology developed in recent years to treat such industrial wastewater. Membrane filtration adopts the interception principle, and its essence is to make small molecular substances pass through the membrane through external pressure, and large molecular substances are intercepted. , so as to realize the separation of substances. Membrane fouling has become a bottleneck restricting the development of membrane technology, and eliminating membrane foul...
