The invention discloses a pollution source control and removal method for an underground water organic pollution site, and relates to the technical field of site remediation. Firstly, an underground water pollution source is controlled, and a waterproof curtain is built at the boundary of a polluted area. Then an underground water pollution source is removed in a polluted area excavation and ectopic treatment mode, and polluted underground water is collected through foundation pit dewatering in the excavation process and conveyed to wastewater treatment equipment to be treated; the excavated aquifer medium soil is subjected to ex-situ indirect thermal desorption treatment, adsorbed and residual organic pollutants in the soil medium are heated into a gas state to be separated from soil particles, and generated high-temperature waste gas is subjected to activated carbon adsorption treatment after being pretreated. By monitoring underground water around and inside the remediation area, an underground water pollution source is effectively controlled and removed, and the removal rate of soil and underground water pollutants after treatment is close to 100%. The method is thorough in underground water organic pollution site treatment and high in treatment efficiency.

The invention relates to the technical field of raw materials of skin care products, and particularly discloses an acne-removing composition as well as a preparation method and application thereof. The acne-removing composition comprises the following components in parts by mass: 1.32-4.6 parts of a composite extract; 0.01 to 0.02 part of a skin repairing agent; 10 to 20 parts of a humectant; 75.38 to 88.67 parts of a solvent; the composite extract is prepared by compounding codium tomentosum extract, cryptomeria fortunei bud extract, nymphaea tetragona flower extract, reed extract and ganoderma sinensis extract. The acne-removing mask has the advantages that the acne-removing effect is more thorough, and acnes are not easy to relapse.

The present invention relates to a soil remediation system and a remediation process. The soil remediation system comprises a frame, two through slots are symmetrically arranged on the frame, and a loosening structure which can be lifted and lowered and can pass through one of the through slots is arranged on the frame. The loosening structure cooperates with a plurality of abutting members arranged on the frame to separate the soil adhered to the loosening structure from the loosening structure. A trigger assembly is also arranged on the frame, and the trigger assembly is connected to the loosening structure to drive the loosening structure to lift and lower in a direction perpendicular to the frame. The trigger assembly is also connected to a pouring assembly arranged on the frame, and the pouring assembly is used to evenly spread a soil remediation agent on the loosened soil. When in use, the frame moves on the repaired soil, and the trigger assembly is actuated at the same time to drive the loosening structure to lift and lower periodically to loosen the soil. The rear trigger assembly drives the pouring assembly to evenly spread the soil remediation agent on the soil to perform rapid soil remediation.
