[0065] Please also refer to figure 1 As shown, the coupling device of the sequential batch adsorption aeration filter and the underground soil infiltration in this embodiment includes: a thickening tank 1, a WAR reactor 2, a heat exchanger 10, a PACT tank 3, and an ammonia nitrogen aerated biological adsorption Filter 4, Sewage Return Tank 5, Sewage Denitrification Tank 6, Deep Phosphorus Adsorption Filter 7, and Underground Soil Infiltration 8; wherein, the thickening tank 1 is connected to the WAR reactor 2, and the WAR reactor 2 Connected to the heat exchanger 10, the heat exchanger 10 is connected to the PACT tank 3, the PACT tank 3 is connected to the concentration tank 1 and the ammonia nitrogen aeration biological adsorption filter 4, the ammonia nitrogen aeration The biological adsorption filter 4 is respectively connected to the sewage return tank 5, the sewage denitrification tank 6, and the deep phosphorus adsorption filter 7, and the deep phosphoru...
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 ...
