Problems solved by technology

[0003] Traditional sewage biological treatment technology has a long sewage treatment cycle, large reaction tank volume, large aeration volume, more equipment, complex operation, high cost, and a large amount of sludge that is difficult to handle. This has become a traditional The technical development bottleneck of sewage treatment process
In recent years, the method of using the physiological function synergy between microalgae and bacteria to purify sewage has received widespread attention, but the current device structure for sewage treatment using bacteria and algae is too fixed, which is not easy to disassemble, clean and maintain , is not conducive to improving the efficiency of sewage treatment

Embodiment 1

[0021] see Figure 1-3 , a bacteria and algae composite biofilm sewage treatment device, comprising a treatment box 1, an air pump 12 communicated with an external air source and a water pump 6 communicated with an external sewage source, the top of the treatment box 1 is sealed and connected with a sealing cover plate 25, the treatment A net cage 3 is slidably installed in the box 1, and an aeration ring pipe 22 is fixedly installed in the net cage 3. Several vertically arranged aeration branch pipes 23 are uniformly opened in the aeration ring pipe 22, and the surface of the aeration branch pipe 23 is Aeration holes 24 are evenly opened, and a plurality of aeration branch pipes 23 and the aeration holes 24 on them play a role in fully dispersing and refining the airflow, improving the quality of aeration.

[0022] The surface of the net cage 3 is provided with a biofilm 2, and the bottom of the aeration ring pipe 22 is connected with a connecting gas nozzle 9 extending to th...

Embodiment 2

[0026] On the basis of Embodiment 1, in addition, the side wall of the processing box 1 is provided with a slideway 20 transversely, and a pull plate 17 is slidably installed in the slideway 20. A position post 16, a sealing hole connected to the slideway 20 is provided on the top of the processing box 1, and a snap-in post 15 is sealed and inserted in the sealing hole, and the lower end of the snap-in post 15 is fixedly installed with a magnetic attraction block vertically corresponding to the pull plate 17 18. The inner side wall of the treatment box 1 is vertically provided with a guide groove 13, and the side wall of the cage 3 is fixedly equipped with a guide slider 14 slidingly embedded in the guide groove 13, and the clamping post 15 is fixed on the guide slider 14 bottom surface.

[0027] When the net cage 3 is installed inside the processing box 1, the sealing cover plate 25 is opened, and the net cage 3 is stretched into the processing box 1, and the fixed guide slide...

Abstract

The invention discloses a bacteria and algae composite biological membrane sewage treatment device, and relates to the technical field of water treatment. The device comprises a treatment box, an airpump and a water pump, the air pump is communicated with an external air source, the water pump is communicated with an external sewage source, a sealing cover plate is hermetically connected at the top of the treatment box, an aeration ring pipe is fixedly mounted in a net box, a connecting air nozzle extends out of the net box and is communicated at the bottom of the aeration ring pipe, and a plurality of fluorescent lamps are electrically connected with a solar panel and uniformly arranged on one side, close to the treatment box, of a lamp frame. An aeration component in the device and thetreatment box can be rapidly disassembled and assembled, cleaning and maintaining convenience is greatly improved, light emitted by a fluorescent lamp provides illumination for the respiratory actionof bacterium and algae organisms, rapid growth and metabolism of the bacterium and algae organisms is facilitated, sewage purification is accelerated, air flow generated by aeration is dispersed and buffered by the net box, high air flow impact is avoided, sewage is sufficiently purified by bacteria and algae on a biological membrane, and sewage treatment efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a bacteria and algae composite biofilm sewage treatment device. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. The upstream suppliers in the sewage treatment industry are mainly manufacturers of sewage treatment equipment and suppliers of sewage treatment chemicals. All belong to industries with rapid development and good demand. The traditional sewage biological treatment technology mainly uses microbial metabolism to remove pollutants. The removal of nitrogen and phosphorus is mai...
