High-dissolved-oxygen biodegrading system for sewage treatment and treatment process thereof

Abstract

The invention discloses a high-dissolved-oxygen biodegrading system for sewage treatment. The system comprises a pressurizing pump, an oxygenator, a dissolved oxygen tank, a strain box and a jet device. The pressurizing pump is connected with an outside water source and a water inlet of the dissolved oxygen tank, the oxygenator is connected with the dissolved oxygen tank which is connected with the jet device, and the strain box is connected with the dissolved oxygen tank. A treatment process of the system includes steps: sampling a water body of sewage for test; according to a test result, selecting an optimal strain; installing equipment; commissioning and running the equipment; detecting dissolved oxygen amount of dissolved oxygen water in the dissolved oxygen tank and the water body around the jet device; after the dissolved oxygen amount reaches requirements, adding the strain into the dissolved oxygen tank; detecting indexes of the water body of the sewage; if the indexes of thewater body do not reach requirements, continuing adding the strain, and adding a proper amount of the strain according to different indexes until the water body reaches standards. The high-dissolved-oxygen biodegrading system and the treatment process can purify the sewage continuously, efficiently and stably.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and relates to a high-dissolved oxygen biodegradation system for sewage treatment and a treatment process thereof. Background technique [0002] At present, under the vigorous promotion of national policies, my country's sewage treatment has achieved certain results, but it has not yet met the people's requirements for a better living environment. Therefore, my country's sewage treatment still needs to be persisted for a long time. [0003] The traditional dissolved oxygen sewage treatment system generally inputs air into the sewage water body in the aeration tank through a blower or an air compressor to increase the amount of dissolved oxygen in the water body, so that the water body can meet the breeding requirements of aerobic bacteria. During the reproduction process of aerobic bacteria, the pollutants in the water body are degraded to achieve the purpose of purifying the water body....

AI Technical Summary

Problems solved by technology

However, the power consumption of this dissolved oxygen sewage treatment system is large, which is not conducive to energy saving, and the dissolved oxygen in the water body in the aeration tank is small, generally not exceeding 8mg / L. Due to the small dissolved oxygen, the activity of aerobic bacteria Poor temperature, slow reproduction, resulting in low purification efficiency
