Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment pool for sewage treatment. Background Art

[0002] The biochemical reaction of sludge has precise requirements for temperature. It needs to be within a specific temperature range to efficiently treat sewage. When the weather is cold, the temperature of the sewage will drop accordingly. When the temperature is below a certain temperature, the biochemical reaction of the sludge is slow and the sewage treatment effect is poor. At the same time, in order to effectively remove nitrogen, ammonia and phosphorus pollutants in the water, it is necessary to add chemicals to the sewage treatment pool for treatment.

[0003] After searching, Chinese patent announcement number: CN219567680U discloses a sewage treatment pool for sewage treatment, including a treatment pool, the inner wall of the treatment pool is provided with an interception net, an inlet pipe is provided on the right side of the treatment pool and below the interception net, an overflow pipe is provided on the left side of the treatment pool and above the interception net, and a pneumatic head material assembly extending to the inside of the treatment pool is provided on the top of the treatment pool; the pneumatic head material assembly includes a mounting frame fixedly installed on the top of the treatment pool, a fan is provided on the top of the mounting frame, and an air duct extending to the inside of the treatment pool is fixedly installed on the air outlet end of the fan. The sewage treatment pool for sewage treatment blows air into the air duct through the fan, and after the airflow enters the diversion cabin, it is sprayed into the deep sewage by several diversion pipes. At the same time, the airflow carries the agent into the deep sewage pool when it circulates, and the agent gradually diffuses into the water from bottom to top with the bubbles, so that the agent is evenly integrated into the sewage, thereby avoiding the damage of the agent's properties caused by stirring the agent.

After the device has been running for a long time, the sludge in the sewage will gradually settle and accumulate. When the sludge accumulates too much, it will not only affect the treatment effect of the sewage treatment tank, but also cause a great burden on the operation of the equipment and reduce the service life of the equipment. For this reason, a sewage treatment tank for sewage treatment is proposed to solve the above problems. Utility Model Content

[0032] Specifically: through the reaction net frame 12 fixedly connected to the outer side of the middle part of the bottom end of the mounting plate 3, the sewage precipitated in the pool body 1 can flow into the reaction net frame 12 through a plurality of evenly distributed holes opened on the reaction net frame 12, thereby reacting with the flocculant placed in the reaction net frame 12.
