Sewage treatment device utilizing biological aerated filter

Abstract

The sewage treatment device comprises a water inlet pipe, a filter screen box is arranged on one side of the water inlet pipe, a worker puts a filter screen into a filter screen groove and pushes a spring column to enable a push plate to move downwards, so that a clamping column is clamped in a clamping hole of the filter screen and is separated from a second groove, then a motor is started, and the filter screen box is arranged on the other side of the filter screen box. The motor rotates to drive the first sliding block, the clamping column and the filter screen to move in the direction of the water inlet pipe, when the motor moves to the tail end of the first groove, the filter screen is just matched with the water inlet pipe for use, and when the filter screen needs to be replaced, only the motor needs to be started to rotate reversely, so that the first sliding block, the clamping column and the filter screen move in the direction of the second groove, and the filter screen is replaced. When the filter screen moves to the bottom of the second groove, due to the fact that the upper portion of a clamping column is not controlled, a second spring can drive the clamping column to move upwards into the first groove and the second groove, the clamping column is not connected with the filter screen in a clamping mode any more, the filter screen can be directly taken out, and maintenance and replacement are convenient.

Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment devices utilizing an aerated biological filter tank, in particular to a sewage treatment device utilizing an aerated biological filter tank. Background Art

[0002] Biological treatment of sewage is a general term for treating sewage by biological methods. It is one of the most widely used methods in modern sewage treatment. Anaerobic biological treatment uses anaerobic microorganisms to convert organic matter into organic acids, and methanogens decompose organic acids into methane, carbon dioxide and hydrogen, etc., such as anaerobic ponds, septic tanks, anaerobic digestion of sludge and anaerobic bioreactors. Aerobic biological treatment uses mechanical aeration or natural aeration (such as algae photosynthesis oxygen production, etc.) to provide active energy for aerobic microorganisms in sewage, promote the decomposition activities of aerobic microorganisms, and purify sewage, such as activated sludge, biological filter, biological turntable, sewage irrigation, oxidation pond functions. Biological treatment of sewage has good effect, low cost, simple technology and simple application. When simple sedimentation and chemical treatment cannot guarantee a sufficient degree of purification, biological methods must be used for further treatment. In biological treatment, special attention should be paid to mastering the basic characteristics of microorganisms that purify sewage and meeting their requirements; the ratio of BOD to COD in sewage should be greater than 0.3. Temperature has a greater impact, and the effect is generally poor in winter.

[0003] The sewage treatment device converts organic matter in sewage into simple inorganic matter with the help of microbial decomposition, so that the sewage is purified. The aeration device is a device used to provide oxygen for microorganisms. Before the sewage enters the sewage treatment pool, some fine impurities contained in the sewage need to be filtered with a filter. The filter will be damaged after long-term use. However, the existing filter is fixedly installed inside the water inlet pipe, which is not convenient for disassembly, maintenance and replacement. Utility Model Content

By setting up the blower and turning on the blower, wind passes through the pipe and then through the branch pipe to blow the carbon dioxide generated by the microbial reaction to the bottom of the sewage treatment pool, and then the carbon dioxide is adsorbed by the carbon dioxide absorber at the bottom of the sewage treatment pool, thereby preventing the carbon dioxide from entering the air and protecting the natural environment.

[0007] Optionally, the top and bottom of the filter are provided with clamping holes, which are adapted to clamping columns. The clamping columns can be clamped with the clamping holes, so that the filter can be installed inside the filter slot.

[0008] Optionally, the motor is installed inside the filter box, and the first grooves are arranged at the top and bottom of the filter slot. By setting the first grooves, the first slider can be limited in movement in the first grooves.

[0009] Optionally, the motor is a conventional forward and reverse motor in the prior art, and the pool cover is a transparent cover. By setting the pool cover as a transparent cover, it is convenient for operators to observe the internal conditions of the sewage treatment pool, and it is also convenient for sunlight to shine in.

[0010] Optionally, the first sliding block is matched with the first groove, and the slide groove is matched with the clamping column. By setting the slide groove, the clamping column can move up and down inside the slide groove.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The sewage treatment device using an aerated biological filter tank, since the second spring is in a state of no force, the second slider and the clamping column are placed inside the first slider, and one side of the clamping column is flush with one side of the first groove, and the other side of the clamping column extends into the second groove and contacts the push plate. The staff puts the filter into the filter groove, pushes the spring column to make the push plate move downward, so that the clamping column is clamped in the clamping hole of the filter and disengaged from the second groove, and then starts the motor. The motor rotates to drive the first slider, the clamping column and the filter to move in the direction of the water inlet pipe. When moving to the end of the first groove, the filter is just adapted to the water inlet pipe. When the filter needs to be replaced, it is only necessary to start the motor to rotate in the opposite direction, so that the first slider, the clamping column and the filter move in the direction of the second groove. When moving to the bottom of the second groove, since the upper part of the clamping column loses control, the second spring will drive the clamping column to move upward to the inside of the first groove and the second groove, and the clamping column is no longer clamped to the filter, and the filter can be directly taken out, which is convenient for maintenance and replacement.

[0013] 2. The sewage treatment device using an aerated biological filter is equipped with a blower. When the blower is turned on, the wind passes through the pipeline and then the branch pipe to blow the carbon dioxide produced by the microbial reaction to the bottom of the sewage treatment tank. The carbon dioxide is then adsorbed by the carbon dioxide absorber at the bottom of the sewage treatment tank, thereby preventing the carbon dioxide from entering the air and protecting the natural environment.
