This utility model belongs to the field of soil pollution leaching, specifically a leaching device for soil pollution remediation. It includes a leaching apparatus with a double crushing mechanism at the top. The double crushing mechanism includes a holding shell, the bottom of which is fixedly connected to the top of the leaching apparatus, and a support plate fixedly connected to one side of the holding shell. This utility model uses a motor to drive a first synchronous wheel and a crushing roller to rotate. The crushing roller rotates and pounds the soil, crushing larger stones to prevent them from clogging the feed inlet and reducing leaching efficiency. The rotation of the first synchronous wheel drives a synchronous belt, which in turn drives a second synchronous wheel and a gear to rotate. The gear's rotation drives another gear to rotate relative to it, which in turn drives two crushing rollers to rotate relative to each other, further crushing the stones in the soil and improving the subsequent leaching efficiency.

The invention relates to the technical field of muck washing and spraying wastewater treatment, in particular to a muck washing and spraying wastewater decrement purification system and method based on a freezing method, a freezing treatment device is used for receiving washing and spraying water precipitated and filtered by a precipitation filter cartridge, and the precipitation filter cartridge is used for removing solid particles in washing and spraying liquid; according to the invention, the sewage is treated by a freezing method, so that the sewage with complex components can be directly treated, the complexity of multi-stage treatment in the prior art is avoided, a relatively great resource utilization effect can be achieved, and the generated purified water can be considered to be reused for spraying or other links if the water quality reaches the standard, so that resource utilization is realized; formation of ice crystals is slowed down by disturbing water flow, the effect of guiding the icing direction is achieved, compared with the mode that icing guiding is conducted through local temperature rise, the utilization rate of a cold source is higher, the situation that local temperature rise influences the overall cooling speed is avoided, the device can act on a larger area, and the cooling efficiency is improved. The larger the acting area is, the lower the possibility of the ice crystal entrainment phenomenon is.

The invention provides a multi-stage screening and pollutant stripping soil leaching remediation device, and relates to the field of soil remediation device.The multi-stage screening and pollutant stripping soil leaching remediation device is used for screening soil soaked with a leaching agent and comprises a plurality of reaction tanks which are sequentially stacked and arranged from bottom to top; and two adjacent reaction tanks are communicated with each other. According to the multi-stage screening and pollutant stripping soil leaching remediation device, the multiple reaction tanks are arranged from bottom to top, and it is ensured that pollutants are thoroughly stripped from soil. The screening groove and the rubber plate are installed in the reaction tank, the effect that the screening groove is driven to jolt and vibrate up and down and soil is loosened through preliminary vibration is achieved, the contact probability of an eluting agent and the interior of the soil is increased, and the pollutant removing effect is improved. And subsequent continuous vibration achieves the draining effect, and the effect that the soil is separated from the eluting agent is improved. A traditional leaching and soaking mode is replaced, so that the soil can be in full contact with a leaching agent, the soil cleaning rhythm is accelerated, and the remediation efficiency is improved.
