Sewage and wastewater treatment, also known as wastewater treatment, refers to the removal of impurities in wastewater through physical, chemical, biological and other methods to meet the specified discharge standards or reuse standards. This is an important link in environmental protection and a key measure to achieve sustainable utilization of water resources. The methods of sewage and wastewater treatment mainly include physical methods, chemical methods and biological methods. Sewage and wastewater treatment usually includes stages such as pretreatment, primary treatment, and advanced treatment. Among them, the pretreatment stage mainly conducts preliminary physical treatment on the wastewater; the primary treatment stage mainly separates suspended solids in the wastewater; the advanced treatment stage further treats the wastewater that has undergone primary treatment to improve the purification effect of the wastewater.

[0003] The grille for sewage treatment is an important device in the sewage treatment process, mainly used to intercept larger solid wastes and floating objects in the sewage, prevent them from entering the subsequent treatment units, and thus ensure the smooth progress of sewage treatment. The grille mainly plays a role in pretreatment in sewage treatment, intercepting large particulate solids and floating objects: preventing these substances from entering the subsequent treatment units and affecting the treatment effect, protecting the treatment equipment: by intercepting large particulate substances, reducing the wear and damage of the equipment, and improving the treatment efficiency: after pretreatment, the impurities in the sewage are reduced, and the efficiency of the subsequent treatment units can be improved.

[0004] When installing a grille at the inlet of sewage treatment, due to filtering solid wastes and floating objects in the sewage, it is necessary to regularly disassemble and maintain the grille. However, considering that when disassembling and maintaining the grille, it is not convenient to disassemble the grille as a whole, which will delay the use efficiency of the grille. There are problems of time-consuming and laborious disassembly of many bolts, which is extremely inconvenient. Therefore, there is an urgent need for a grille structure for sewage and wastewater treatment that is convenient for disassembly to solve the above problems. Content of the Utility Model
