Multi-mode mobile integrated wastewater treating equipment for repairing polluted soil and groundwater

Abstract

The invention relates to multi-mode mobile integrated wastewater treating equipment for repairing polluted soil and groundwater. The equipment comprises an oil separating basin, a regulating basin, a neutralizing and flocculating tank, a sloped plate sedimentation basin, a middle water basin and an integrated control reaction chamber, wherein a control system, medicine adding pots, an ozone generator, an ozone reactor, an activated carbon filtering basin and a sand filtering basin are arranged in the integrated control reaction chamber; the oil separating basin, the regulating basin, the ozone reactor, the neutralizing and flocculating tank, the sloped plate sedimentation basin, the middle water basin, the sand filtering basin and the activated carbon filtering basin are sequentially connected through a pipeline, the ozone generator and the ozone reactor are connected through the pipeline, the medicine adding pots and the neutralizing and flocculating tank are connected through the pipeline, and the medicine adding pots, the ozone generator, the oil separating basin, the regulating basin, the ozone reactor, the neutralizing and flocculating tank, the sloped plate sedimentation basin, the middle water basin, the sand filtering basin and the activated carbon filtering basin are electrically connected with the control system and controlled by the control system. The multi-mode mobile integrated wastewater treating equipment disclosed by the invention can perform innocent treatments on wastewater generated during repairing the polluted soil and the groundwater, aiming at wastewater in different nature, different technologies are combined, technology parameters are regulated, and different medicine agents are added, so that the treated wastewater can reach a discharge standard or be used for other application.

Description

technical field [0001] The invention relates to a multi-mode mobile integrated waste water treatment equipment for repairing polluted soil and groundwater. Background technique [0002] It is understood that 1 / 3 of my country's total water resources is groundwater, and a large number of observation data show that the pollution of China's groundwater is quite serious. The unreasonable discharge of urban and industrial "three wastes" (waste water, waste gas, and waste residue) has aggravated the trend of urban groundwater pollution; the extensive use of pesticides and chemical fertilizers has caused widespread pollution of shallow groundwater in agricultural and pastoral areas. The groundwater pollution that needs remediation is more serious. Generally, when remediating contaminated soil, it is also necessary to remediate the groundwater in the corresponding area. [0003] At present, the groundwater remediation technologies at home and abroad mainly include extraction treatm...

Problems solved by technology

The baffled anaerobic reactor used has disadvantages such as complicated process, high failure rate, difficult operation and maintenance, poor and unstable effluent quality (after treatment, wastewater is reused for oil field drilling) and other shortcomings

It has been reported that the Chinese patent CN203866134U is named as a mobile wastewater treatment device, which mainly treats industrial production wastewater, and performs processes such as reaction, neutralization, coagulation, air flotation and filtration. Pollutant wastewater, and the treatment effect is not ideal, and the scale of wastewater treatment is also small
