Abstract

The invention belongs to the technical field of treatment of phosphorus-containing and nitrogen-containing sewage, and particularly relates to integrated sewage treatment equipment capable of realizing efficient synchronous nitrogen and phosphorus removal sewage treatment integrated equipment and a treatment method thereof. The equipment comprises an anoxic tank I (1), an aerobic tank I (2), an anoxic tank II (3), an aerobic tank II (4), a sedimentation tank (5) and a clean water tank (6), and is characterized in that the anoxic tank I (1), the aerobic tank I (2), the anoxic tank II (3), the aerobic tank II (4), the sedimentation tank (5) and the clean water tank (6) are arranged in one shell side by side; each tank body is divided by a partition plate; etc. With the equipment and the method, the total phosphorus removal rate of the sewage is greater than 95%, the total nitrogen removal rate of the sewage is greater than 90%, the total nitrogen and total phosphorus removal rates are improved compared with existing traditional equipment, and the treatment requirements of sewage with relatively higher ammonia nitrogen and total phosphorus contents are met.

Description

technical field [0001] The invention belongs to the technical field of phosphorus- and nitrogen-containing sewage treatment, and specifically relates to an integrated equipment for efficient and synchronous nitrogen and phosphorus removal sewage treatment and a treatment method thereof. Background technique [0002] At present, the traditional synchronous denitrification and phosphorus removal sewage treatment integrated equipment is equipped with anaerobic pond, anoxic pond, aerobic pond, sedimentation pond and clear water pond. The main reaction parts are anaerobic pond, anoxic biochemical pond and aerobic biochemical pond. It belongs to the anaerobic-anoxic-aerobic biological simultaneous nitrogen and phosphorus removal process, and is the simplest simultaneous nitrogen and phosphorus removal process. Due to the different dominant bacterial genera of biological denitrification and biological phosphorus removal, the optimal parameters of sludge age are quite different, and...
