Unit-type bionic oxygen-carrying technological sewage purification device

Abstract

The invention discloses a unit-type bionic oxygen-carrying technological sewage purification device. The device comprises a vertical aeration pipe, wherein an aeration device is arranged at the lower part inside the vertical aeration pipe; an oxygen-carrying carrier is arranged inside the vertical aeration pipe above the aeration device, and a liquid outlet is formed in the side wall of the vertical aeration pipe at the bottom end of the aeration device; the liquid outlet of the vertical aeration pipe is connected with a liquid outlet pipe; and a teflon filter screen is arranged in the liquid outlet pipe. According to the device, the space is saved, and the aim of purifying sewage can be achieved since aerobic, anaerobic and facultative anaerobic reactions are performed by special carrier and immobilized microorganisms; and aeration of an aeration tank is carried out quantitatively and regularly, so that energy required by aeration can be greatly saved, and the aims of energy saving and high efficiency can be achieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a unitary bionic oxygen-carrying technology sewage purification device. Background technique [0002] In many occasions, it is necessary to increase the dissolved amount of oxygen in water, such as aerobic fermentation, sewage aeration, aquaculture, aquatic product transportation, etc. But normally the solubility of oxygen in water is very low. The method efficiency of aerating water to improve oxygen content in water is very low, generally 5-30%, has caused the waste of energy. [0003] At present, the method of sewage treatment at home and abroad mostly uses the method of anaerobic plus activated sludge aeration, and aeration accounts for about 70% of the cost. Its disadvantages are high basic investment, large floor area, and certain impact on the surrounding environment; due to the low solubility of oxygen in water, the utilization rate of oxygen is not high, resul...

AI Technical Summary

Problems solved by technology

The disadvantage is that the basic investment is high, the floor area is large, and it has a certain impact on the surrounding environment; due to the low solubility of oxygen in water, the utilization rate of oxygen is not high, resulting in high unit sewage treatment costs

Reducing the cost of sewage treatment has become an urgent task for the industry. Since the essence of sewage treatment is microbial degradation, supplemented by chemical and physical methods to degrade and separate polluted components in water, improving the degradation efficiency of microorganisms is the key to reducing sewage treatment costs. The key, and the utilization rate of oxygen in the aeration process is not only related to the degradation efficiency of microorganisms, but also greatly affects the cost of sewage purification
