The invention relates to devices which are arranged in catch basins embedded in roadsides or buildings or other grounds and can collect floatage or various kinds of garbage washed off by rainwater, in particular to a sewer rain grate with a filter function. The sewer rain grate is characterized in that a filter box, a rain grate body, a flow guide baffle, a filter element and springs are included; a plurality of inflow holes are formed in the filter box, and the filter box is used for filtering out floatage and sundries; the rain grate body is provided with a visual determination device and used for discharging the floatage and the sundries into the inflow holes; the flow guide baffle is arranged below the rain grate body and guides the entering floatage and sundries into the filter box; the filter element is arranged outside the filter box and used for improving the quality of rainwater flowing through the filter box and includes activated carbon; the springs are connected and arranged on the two sides of the filter box and the two sides of the rain grate body. According to the sewer rain grate with the filter function, the floatage and sundries entering the rain grate along with rainwater can be filtered out in the rainy days, and the situation that a sewer is blocked to lose the function is avoided. When excess floatage exceeds the height of the filter box due to rainstorms and the like, water can flow out of a clearance between the filter box and the flow guide baffle, the filter box cannot be blocked, and the sewer can work normally.
