The invention discloses an anti-clogging textile bleaching and dyeing sewage treatment plant, which comprises a main box, a sewage inlet pipe, a drainpipe, a second box, an ultraviolet germicidal lamp, a first filter screen plate, a second filter screen plate, a vertical baffle plate, a first silk thread grabbing device and a second silk thread grabbing device. Through the silk thread grabbing devices for grabbing silk threads and fibers in textile bleaching and dyeing sewage, silk threads and fibers are prevented from blocking the sewage treatment plant. by arranging the first filter screen plate, the second filter screen plate and a filter core inside the main box to filter the textile bleaching and dyeing sewage for three times, harmful substances in the textile bleaching and dyeing sewage can be effectively reduced. Through the arrangement of the ultraviolet germicidal lamp for sterilizing the textile bleaching and dyeing sewage, breeding of bacteria is reduced. In comparison withthe traditional technologies, the invention has the following beneficial effects: most water meets requirements of industrial reuse, discharge of wastewater can be reduced, resources are saved, and the environment is protected; and the anti-clogging textile bleaching and dyeing sewage treatment plant has advantages of low investment cost, low energy consumption, high treatment efficiency and the like.
