Sewage slag salvaging grillage machine and sewage treatment system

The invention relates to a sewage slag salvaging grillage machine and a sewage treatment system. The sewage slag salvaging grillage machine comprises a grillage which comprises a slag salvaging bottom face and slag salvaging side edges on the two sides of the slag salvaging bottom face, a grillage transmission device and a grillage transmission motor, wherein the slag salvaging bottom surface is configured to be of a filtering net structure made of an alloy material. The slag salvaging bottom surface of a grillage is designed into the filtering net-shaped structure made of the alloy material, so that the contact surface is increased in the slag salvaging process, small suspended solids are prevented from entering a sedimentation tank through the grillage machine, the interception efficiency of the small suspended solids is improved, and the treatment efficiency of a subsequent process is improved. 本公开涉及一种污水捞渣格栅机和污水处理系统，其中，污水捞渣格栅机包括：格栅，其包括捞渣底面及其两侧的捞渣侧边；格栅传动装置；和格栅传动电机；其中，捞渣底面被配置为由合金材料制成的过滤网状结构。通过将格栅的捞渣底面设计成由合金材
