Landfill leachate defoaming scale inhibitor and preparation method thereof

The invention relates to a landfill leachate defoaming scale inhibitor, which is prepared from the following raw materials in parts by weight: 30 to 36 parts of polyether and polyether ester, 4 to 8 parts of emulsifying agent, 18 to 24 parts of dispersing agent, 2 to 4 parts of lower alcohol, 0.1 to 1 part of thickening agent, 40 to 50 parts of deionized water and 10 to 15 parts of scale inhibitor. The invention further discloses a preparation method of the landfill leachate defoaming scale inhibitor. Compared with the prior art, the landfill leachate defoaming scale inhibitor has the advantages that the landfill leachate defoaming scale inhibitor is high in defoaming and foam inhibition capacity, good in heat resistance, good in dispersity, simple in preparation process, low in landfill leachate treatment cost, non-toxic, harmless, free of harm to microorganisms, green, environmentally friendly and convenient to use; in addition, the product can also play a role in scale inhibition while defoaming, and preve
