Description

Groundwater heavy metal pollution restoration equipment

Technical Field

The invention belongs to the technical field of groundwater remediation, and particularly relates to groundwater heavy metal pollution remediation equipment.

Background

Groundwater is an important component of water resources, and has stable water quantity, good water quality and one of important water sources for agricultural irrigation, industrial and mining and cities, but some natural or artificial factors (such as forest fires, mining, smelting and the like) can cause the groundwater to be polluted by heavy metals; since heavy metals are difficult to decompose and contain extremely toxic substances, in order to prevent heavy metals from affecting organisms and the environment, an underground water restoration device is needed to restore underground water which has been polluted by heavy metals;

Through retrieval, the device for repairing the heavy metal pollution of the underground water, which is disclosed by the patent number 202211451677.8, comprises a primary filter tank and a treatment tank, wherein a communication end is fixedly arranged between the primary filter tank and the treatment tank, and a separation plate which is inserted with a plurality of communication pipes is fixedly arranged in the communication end; when groundwater passes through the primary filter box, the device can carry out filtering treatment through the filter plate, filtered impurities can be accumulated at one side of the filter plate and at the bucket-shaped bottom, and when the auger rod rotates, the accumulated impurities can be lifted along the lifting pipe barrel; meanwhile, the transverse ball rod can be used for fixedly and frequently abutting against the arc top broad plate on the filter plate, and the vibration spring II is matched with the filter plate to drive the filter plate to vibrate up and down along the end frame, so that the intercepted impurities on one side of the filter plate can be shaken off, the filter plate vibration can also be fixedly and frequently abutted against the leather film at the lower position, and therefore vibration of the leather film is caused to clean the impurities; the dosing branch pipe swings with the U-shaped bracket as the center of a circle to finish dosing, and meanwhile, the hole disc follows the swing to finish mixing of water and the medicament, but the hole disc only agitates underground water up and down, so that a great amount of time is required to be consumed to completely mix the medicament and the water, and large-particle impurities filtered out by the top-placed filter cover can be left in the clamping cylinder, so that the equipment is prevented from being influenced by excessive accumulation of the large-particle impurities in the clamping cylinder, and the primary filter box is required to be opened by closing the equipment to clean the clamping cylinder; in view of the above, a repair device for heavy metal pollution of groundwater is provided, and a filtering device can be cleaned under the condition of normal operation of the device while rapidly mixing a medicament with groundwater.
