Wastewater purifying treatment device

Abstract

The invention discloses a wastewater purifying treatment device. The device is characterized in that a left side of a driving shaft is rotatably connected to a device body through a bearing, wherein aleft end of the driving shaft is fixedly connected to a semi bevel gear; bevel gears are arranged at the upper part and the lower part of the semi bevel gear and are fixedly connected to the upper parts of lead screws; toothed parts of the semi bevel gear are engaged with the bevel gears; the lead screws are rotatably connected to the device body through the bearing; the lead screws are in threaded connection with the middle part of a transverse plate; the upper ends of two sides of the transverse plate are fixedly connected to the lower end of a telescoping rod; the upper end of the telescoping rod is fixedly connected to the device body; supporting rods are rotatably connected to the bearings at the lower parts of two sides of the transverse plate. According to the device, a driven shaft is driven through the lead screws to rotate so as to drive a swinging plate to rotate, and meanwhile, the transverse plate which up and down reciprocates is capable of driving the supporting rods and small rollers to reciprocate to press the swinging plate; the swinging plate swings while rotating, so that gas and liquid can be mixed in a full contact manner, and as a result, the dissolved oxygen of water solution can be greatly increased. The design is reasonable and practicable in structure design, capable of greatly increasing the wastewater purifying efficiency, and time-saving.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a waste water purification treatment device. Background technique [0002] In wastewater purification treatment, the contact area between water and air is often increased by aerating water or mechanical agitation, which is an intermediate process of aerobic biological treatment of wastewater. A water treatment method that uses impeller brushes or other tools to vigorously agitate the water surface, constantly exchanging gaseous substances and removing volatile substances in the water with new interfaces and atmospheric contacts, or allowing gases to escape from the water, such as removing the odor of water or carbon dioxide and Harmful gases such as hydrogen sulfide; or dissolve oxygen into water to increase the concentration of dissolved oxygen to achieve the purpose of removing iron and manganese or promoting the degradation of organic matter by aerobic microorganisms.

AI Technical Summary

Problems solved by technology

[0003] At present, most of the existing sewage treatment devices have insufficient gas-liquid mixing, which leads to poor sewage treatment effect, and requires multiple cycles of aeration to decontaminate, which consumes a lot of time and is not efficient.
