Example Embodiment

[0084] Example 3

[0085] The device described in Example 1 was used for sewage treatment.

[0086] Sewage is fed by sequential batches. The time interval is 12h. The sewage enters PACT tank 3. The adsorption of powdered activated carbon in PACT tank 3 and the biodegradation of biochemical sludge are used to remove organic pollutants in the sewage. Convert to CO 2 And H 2 O, ammonia nitrogen is converted into nitrate nitrogen, and heavy metal ions are solidified and precipitated under the action of red mud molecular sieve to purify sewage; the supernatant of PACT tank 3 is introduced to ammonia nitrogen aerated biological adsorption filter 4, and ammonia nitrogen is adsorbed on the natural After adsorption of zeolite or artificial zeolite (NH 3 -N removal rate can reach 99%), valve A is closed, valve B is opened, and the sewage flows into the sewage return tank 5 for storage. At the same time, nitrifying bacteria was added to the ammonia nitrogen aeration adsorption filter 4, and ...
