Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to MBBR integrated sewage treatment equipment. Background Art

[0002] The MBBR process principle is to use the basic principle of the biofilm method, make full use of the advantages of the activated sludge method, and overcome the shortcomings of the traditional activated sludge method and the fixed biofilm method. This method increases the biomass and biological species in the reactor by adding a certain number of carriers to the reactor, thereby improving the treatment efficiency of the reactor. During aeration, it is completely mixed with water, and the environment for microbial growth is gas, liquid, and solid. The collision and shearing effect of the carrier in the water makes the air bubbles smaller and increases the utilization rate of oxygen. In addition, each carrier has different biological species inside and outside, some anaerobic bacteria or facultative aerobic bacteria grow inside, and most of the outside are aerobic bacteria. In this way, each carrier is a microreactor, so that nitrification and denitrification reactions can exist simultaneously to a certain extent, thereby improving the treatment effect. Before the sewage is treated by MBBR, a series of pretreatment operations are required.

The sewage enters the first treatment box 1 through the first water inlet pipe 4, and the sewage passes through the MBBR suspended filler 2 inside the first treatment box 1. The sewage is treated by the MBBR suspended filler 2, and the treated water is discharged through the outlet channel 3. The organic matter, ammonia nitrogen, phosphorus and other pollutants in the sewage are removed by the MBBR suspended filler 2, thereby achieving the purpose of purifying water quality.

Large particles of impurities in the sewage are filtered through the second filter screen 63, and the sewage is subjected to a first pretreatment operation.

[0028] The spring assembly 64 includes a fixed block 641, which is arranged on the inner wall of the second processing box 61. A sliding shaft 642 is provided on the top of the fixed block 641, and the sliding shaft 642 passes through the second filter screen 63. A circular limit plate 643 is provided on the top of the sliding shaft 642. A spring 644 is sleeved on the outer surface of the sliding shaft 642. The spring 644 is arranged between the fixed block 641 and the second filter screen 63. The spring 644 vibrates the second filter screen 63 to prevent the second filter screen 63 from being blocked.

[0029] The driving assembly 65 includes a second motor 651, which is arranged on one side of the second processing box 61. The output end of the second motor 651 is connected to the rotating shaft 652 for transmission. The rotating shaft 652 extends into the second processing box 61. A cam 653 is provided on the rotating shaft 652.

The filtered sewage is pumped out by the second water pump 67, and then enters the next process through the second water inlet pipe 66. The large particles of solid impurities in the sewage are filtered by the second filter screen 63, which prevents the large particles of impurities from directly entering the MBBR filler treatment chamber, thereby not causing blockage in the treatment chamber and not destroying the microorganisms on the MBBR filler, thereby ensuring the effect of sewage treatment, saving a lot of working time, and improving work efficiency.
