Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a sewage treatment system with multiple filtering and purification functions. Background Art

[0002] At present, sewage treatment refers to the process of purifying sewage before it is discharged into water sources or reused; sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical treatment, and catering. Existing sewage treatment methods include filtration sedimentation, biofilm, and activated sludge. Existing pollution control systems are usually modular structures of integrated boxes, and sewage flows in one direction in the modular structure. A series of methods such as physical interception, chemical precipitation and adsorption, and microbial degradation are used to treat sewage, so that pollutants in the water can be removed and the sewage can meet the discharge standards. For example, a Chinese patent with publication number CN211394182U discloses a three-dimensional intelligent water treatment system, which includes a pretreatment system, a bacterial colony re-cultivation system and a pH adjustment system which are sequentially connected along the sewage inlet route. The pretreatment system is configured to filter impurities and particulate matter in the water. The bacterial colony re-cultivation system includes a sterilization unit located downstream of the pretreatment system and a probiotic breeding unit located downstream of the sterilization unit. The pH adjustment system includes a fine-grained biochemical ball treatment pool located downstream of the probiotic breeding unit, and the fine-grained biochemical ball treatment pool is configured to adjust the pH of the water.

[0003] The existing pollution control system is usually difficult to disassemble after installation. When the amount of sewage that needs to be treated in different periods is different, it is easy to increase the number of module structures according to demand due to site limitations. The module structure is a single box structure. If excessive sewage flows unidirectionally in the module structure, it will increase the workload of the module structure, and water accumulation and leakage are likely to occur, making it difficult for the pollution control system to adapt to long-term pollution control operations, reducing the working efficiency of the pollution control system.

[0036] The sewage treatment system inputs and discharges sewage through the liquid inlet pipe 9 and the liquid outlet pipe 10 on the upper module structure. The sewage in the inner cavity of the box body 1 flows from the liquid inlet cavity to the liquid outlet cavity in one direction through the one-way valve structure in each partition wall body 5. The liquid in the warehouse cavity enters the installation shell 151 through each first through hole 18. The porous ceramsite 152 uses organic mud, which is first crushed and stirred, and then a variety of effective composite probiotics are added.
