Problems solved by technology

[0002] The general treatment process of industrial wastewater and domestic sewage includes: chemical primary treatment method of flocculation sedimentation and filtration in settling tank. This method is simple in process, low in cost, and can remove most pollutants; but it occupies a large area and seriously pollutes organic matter. Sewage treatment is difficult to meet discharge standards
Chemical primary treatment → biodegradation method, this method overcomes the shortcomings of poor treatment effect of chemical primary treatment method, but the treatment cycle is long, sensitive to natural temperature, water quality changes and other factors, and the process stability is not good
Chemical primary treatment → chemical oxidation degradation chemical secondary enhanced treatment method, this method is simple in process and fast in treatment speed, but consumes a lot of chemicals and is prone to secondary pollution
Chemical primary treatment→electrochemical oxidation degradation method, this method is simple in process, fast in processing speed and good in effect, but consumes a lot of energy and is generally unacceptable economically

Embodiment 1

[0020] The filling volume of irregular fly ash sewage treatment materials is 80×50×50cm, which is as big as a thumb to a small egg. 3 The flocculation filtration degradation bed. The dyeing and finishing sewage is lifted from the storage tank to the sewage supply tank by the water pump, and then flows in from the bottom of the flocculation filtration degradation bed and flows out from the top at a flow rate of 50L / h, and flows naturally through the 1st to 6th flocculation filtration degradation beds in turn. The compressor blows air from the bottom of the flocculation filtration degradation bed, and the air blowing volume is 45L / m 3 h. The ozone provided by the ozone generator is mixed with the treated water flowing out of the sixth-stage flocculation filtration degradation bed through the mixing pump, and enters the ozone treatment tank for further deep oxidation. The amount of ozone added is 30mg / L. The treated water then flows into the deozone tank, with a blowing volume ...

Embodiment 2

[0028] The filling volume of irregular fly ash sewage treatment materials is 80×50×50cm, which is as big as a thumb to a small egg. 3 The flocculation filtration degradation bed. Paper processing sewage is lifted from the storage tank to the sewage supply tank by the water pump, and then flows into the bottom of the flocculation filtration degradation bed and flows out of the top at a flow rate of 40L / h, and flows through the 1st to 5th flocculation filtration degradation bed naturally in turn. The air compressor blows air from the bottom of the flocculation filtration degradation bed, and the air blowing volume is 55L / m 3 h. The ozone provided by the ozone generator is mixed with the treated water flowing out of the fifth-stage flocculation filtration degradation bed through the mixing pump, and enters the ozone treatment tank for further deep oxidation. The amount of ozone added is 25mg / L. The treated water then flows into the deozone tank, with a blowing volume of 55L / m ...

Embodiment 3

[0036] The filling volume of irregular fly ash sewage treatment materials is 80×50×50cm, which is as big as a thumb to a small egg. 3 The flocculation filtration degradation bed. The closed pond water is lifted from the storage tank to the sewage supply tank by the water pump, and then flows into the bottom of the flocculation filtration degradation bed and flows out of the top at a flow rate of 60L / h, and flows naturally through the 1st to 4th flocculation filtration degradation beds in turn, and at the same time by The air compressor blows air from the bottom of the flocculation filtration degradation bed, and the air blowing volume is 30L / m 3 h. The ozone provided by the ozone generator is mixed with the treated water flowing out of the fourth-stage flocculation filtration degradation bed through the mixing pump, and enters the ozone treatment tank for further deep oxidation. The amount of ozone added is 20mg / L. The treated water then flows into the deozone tank, with a b...

Abstract

The present invention relates to one kind of waste water treating method integrating flocculation, adsorption, oxidizing degradation and filtering. The waste water treating process includes pumping waste water from the accumulator to waste water supplying tank, flowing from the bottom into flocculating, filtering and degrading bed and flowing out from the top, blowing in air with air compressor from the bottom of the bed, mixing ozone from the ozone generator and the treated water in a mixing pump, flowing into the ozone treating tank, flowing into ozone eliminating pond, and exhaust. The present invention may be used in treating city domestic sewage, dyeing and finishing effluent, papermaking effluent, etc.
