The invention discloses biological pollutant industrial environmental protection equipment which comprises an equipment body, a cavity is formed in the equipment body, a filter screen is arranged in the cavity, a clamping plate is arranged on one side of the filter screen, a pressing block is arranged in the clamping plate, spring grooves are formed in the two sides of the pressing block, and extension springs are arranged in the spring grooves. A first telescopic rod is arranged in the extension spring, a second telescopic rod is arranged at the bottom of the first telescopic rod, and a fixing plate is arranged on the side, away from the clamping plate, of the filter screen. According to the biological pollutant industrial environmental protection equipment, by arranging the clamping plates and the fixing plates, the purposes of facilitating replacement of a filter screen, simplifying disassembly and assembly of the filter screen, reducing the working intensity of workers and improving the working efficiency can be achieved, by arranging a dust collection box, a bearing and an air pipe, the application range of the equipment can be expanded, and the practicability is high. And dust in the equipment can be conveniently cleaned, and the practicability is enhanced.
