Problems solved by technology

Due to the large change in the volume of wastewater and the high concentration of pollutants, these pretreatment methods mostly use multi-stage series operation, many structures, large floor area, difficult operation and management, large consumption of chemicals, large amount of sludge generation, and poor quality of effluent water. Not ideal, poor water quality stability

Embodiment 1

[0024] Embodiment one, see Figure 1~3 As shown, an industrial sewage plasma pretreatment system includes a base, a control cabinet, a freeze dryer, and a sewage plasma pretreatment device that are arranged on the base and connected in sequence. A support frame is provided at the end of the base, and the sewage plasma pretreatment device is fixed. On the support frame, a control unit and a blower are arranged in the control cabinet. The refrigerated dryer, the sewage plasma pretreatment device and the blower are respectively connected to the control unit for signals. The output pipe of the blower is connected with the air inlet of the refrigerated dryer. The compressed air outlet of the machine is connected with the input port of the sewage plasma pretreatment device through the compressed air delivery main pipeline, and the output pipeline of the sewage plasma pretreatment device is connected with the aeration pipeline system through the industrial sewage treatment pipeline. T...

Embodiment 2

[0028] Embodiment two, see Figure 4 As shown, a pretreatment method for industrial wastewater, industrial wastewater enters the advection oil-separating grit chamber for oil-separating sedimentation treatment, and the effluent directly enters the homogeneous and even-quantity regulating tank, and the above-mentioned aeration pipeline system is used in the regulating tank. The plasma ozone output from the industrial sewage plasma pretreatment system is fully aerated, and enters the biochemical system after full aeration, making full use of the bactericidal ability of ozone as an efficient broad-spectrum non-residual pollution gas disinfectant, the sewage treatment effect is better, and it can quickly And completely eliminate all kinds of peculiar smells in the air and water, and there are fewer harmful residues in the water; the residence time of the wastewater in the regulating tank is longer, and the partially dissolved or suspended substances in the wastewater are changed th...

Abstract

The invention relates to a plasma pretreatment system for industrial sewage, which comprises a base, a control cabinet, a refrigerated dryer, and a sewage plasma pretreatment device. A control unit and a blower are arranged in the control cabinet, and the output pipe of the blower communicates with the air inlet of the refrigerated dryer. , the compressed air outlet of the refrigerated dryer communicates with the input port of the sewage plasma pretreatment device through the compressed air delivery main pipeline, and the output pipeline of the sewage plasma pretreatment device communicates with the aeration pipeline system through the industrial sewage treatment pipeline, and the sewage plasma The pretreatment device includes a number of ozone generating modules which are connected to the main compressed air delivery pipeline sequentially through branch pipelines. The invention has high energy utilization rate, ensures the ozone demand for the aeration pipeline system, and further ensures the efficiency of industrial sewage pretreatment and the quality of effluent.

Description

technical field [0001] The invention relates to the field of industrial sewage treatment, in particular to an industrial sewage plasma pretreatment system and an industrial sewage pretreatment method. Background technique [0002] In the operation of existing sewage plants, the investment and operation cost of sewage treatment is huge, even accounting for about 70% of the investment and operation cost. In order to facilitate management and save operating costs, most sewage needs to be treated biochemically. Necessary pretreatment must be carried out before biochemical changes to reduce the concentration of pollutants, balance water quality and quantity, and reduce the biological toxicity of wastewater. The usual pretreatment methods include primary sedimentation method, coagulation sedimentation method, coagulation air flotation method and regulating tank method. Due to the large change in the volume of wastewater and the high concentration of pollutants, these pretreatment...
