Problems solved by technology

[0003] At present, the aerobic biological treatment used in domestic industrial wastewater treatment is mainly traditional activated sludge method and biofilm method. Due to its complex process, large area, high investment and low degree of automation, wastewater treatment, especially The development of industrial wastewater treatment engineering construction is slow, and the normal operation and management of treatment facilities is difficult. Therefore, the traditional process is reformed to develop a biological treatment process with high efficiency, small footprint, and low investment, and it can realize automatic control. , it is of great significance to promote my country's industrial wastewater treatment and better realize scientific and modern maintenance and operation

Embodiment Construction

[0025] The sewage to be treated is the beer wastewater discharged from the brewery. The sewage treatment steps are as follows:

[0026] (1) After the sewage enters the anaerobic baffle reactor from the water tank, it undergoes anaerobic reaction for 24 hours. During the anaerobic reaction, the dissolved oxygen in the reactor was 0.

[0027] (2) A pool is filled with water, without aeration, and the agitator is started to stir; B A Pool aeration; C pool sedimentation and water discharge.

[0028] (3)B A pool water; A, B(B A , B B , B C The three ponds are referred to as the B pond, the same below) are all aerated; the C pond settles and discharges water.

[0029] (4)B A Water enters the pool; sedimentation in pool A; aeration in pool B; sedimentation and water outflow in pool C.

[0030] (5) Pool C is filled with water without aeration, and the agitator is started to stir; pool B is aerated; pool A is sedimented and water is discharged.

[0031] (6)B C Water enters th...

Abstract

The method of utilizing active sludge in processing beer waste water includes the following steps. In the anaerobic reaction step, beer waste water enters to the anaerobic baffle reactor from water tank for anaerobic reaction of 24 hr while dissolved oxygen concentration in the anaerobic baffle reactor is controlled as zero. The second step is the aerobic reaction one of 8 hr. The present invention realizes the elimination of organic matter, ammonia nitrogen and total phosphate in relatively high concentration of beer waste water.

Description

technical field [0001] The invention belongs to the field of industrial wastewater treatment, and more specifically relates to a method for treating beer wastewater with an integrated activated sludge process. Background technique [0002] As the main process in the wastewater treatment process, biological treatment process is widely used at home and abroad. For high-concentration organic industrial wastewater, the combination of anaerobic and aerobic treatment processes is currently widely recognized by the sewage treatment industry and has become a development trend. [0003] At present, the aerobic biological treatment used in domestic industrial wastewater treatment is mainly traditional activated sludge method and biofilm method. Due to its complex process, large area, high investment and low degree of automation, wastewater treatment The development of industrial wastewater treatment engineering construction is slow, and the normal operation and m...
