Alkyl glucoside is a new type of nonionic surfactant. Compared with other surfactants, it has the characteristics of stability, non toxicity, solubility, biodegradability and low irritation to skin. Advantages: high surface activity, high viscosity, rich foam, fine and stable. It has obvious synergistic effect with other surfactants, so it can be used as detergent, detergent, cosmetic surfactants, pharmaceutical additives and industrial emulsifiers.

1) Soil cleaning: the remediation effect is good.

Process flow: excavation of contaminated soil, cleaning and remediation of contaminated soil, solid-liquid separation of cleaned soil, treatment of residual materials and final soil treatment. A kind of

2) It can be used for remediation of soil contaminated by petroleum.

Principle: by using the hydrophobicity and solubilization of the eluent, the petroleum pollutants in the soil are transferred to the liquid phase, and the liquid phase is removed from the soil for other treatment, and then discharged or reused.

3) Thermal decomposition absorption remediation: the cost is high, and there are problems of soil backfill after remediation.

Principle: using the understanding of the characteristics of petroleum components, the contaminated soil is excavated and placed in a certain equipment for heating to a certain temperature, so that the oil components in the soil become gas and volatilize at different boiling points. A kind of

4) Vapor phase suction remediation: suitable for gasoline and other low boiling point oil components pollution; good permeability, average value of unsaturated soil; but, the equipment requires advanced, high cost. A kind of

Principle: to strengthen the directional flow of soil air by extracting gas phase in unsaturated zone of underground layer, so that the flowing gas phase carries petroleum pollutants to the ground and collects them for further treatment. A kind of

Alkyl glucosides have the advantages of ordinary nonionic and anionic surfactants: high surface activity, high viscosity, rich foam, fine and stable, synergistic effect with other surfactants, strong dispersing ability of calcium soap, can be used in hard water, low irritation to epidermis, mucous membrane and living cells, easy biodegradation in the natural environment and less environmental pollution. APG is prepared by condensation of starch or its hydrolyzed sugar with fatty alcohol. The raw materials of APG are very wide, and have attracted more and more attention in recent years.
