Problems solved by technology

The above-mentioned processes have made great contributions to sewage treatment for a period of time. However, with the stricter water environment regulations in various countries and the rapid development of science and technology, these methods consume high energy consumption, and the operation and management work is more complicated. Therefore, in order to meet the strict requirements in the field of environmental protection in the new era and the increasingly severe energy situation, both at home and abroad have begun to develop new types of sewage treatment processes that are environmentally friendly and consume less energy.

[0065] Please also refer to figure 1 As shown, the coupling device of the sequence batch adsorption aeration filter and underground soil infiltration in this embodiment includes: a concentration pool 1, a WAR reactor 2, a heat exchanger 10, a PACT pool 3, and ammonia nitrogen aeration biosorption Filter 4, sewage reflux pool 5, sewage denitrification pool 6, deep phosphorus adsorption filter 7 and underground soil infiltration 8; wherein, the concentration pool 1 is connected to the WAR reactor 2, and the WAR reactor 2 Connect the heat exchanger 10, the heat exchanger 10 is connected to the PACT pool 3, the PACT pool 3 is respectively connected to the concentration pool 1 and the ammonia nitrogen aerated biosorption filter 4, and the ammonia nitrogen aeration The biosorption filter 4 is respectively connected to the sewage reflux pool 5, the sewage denitrification pool 6 and the deep phosphorus adsorption filter 7, and the deep phosphorus adsorption filter 7 is connected to th...

Embodiment 3

[0085] Adopt the device described in embodiment 1 to carry out sewage treatment.

[0086] Sewage adopts the method of sequential batch water intake, and the time interval of water intake is 12 hours. The sewage enters the PACT pool 3, and the organic pollutants in the sewage are removed by the adsorption of powdered activated carbon in the PACT pool 3 and the biodegradation of biochemical sludge. into 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 sieves to purify sewage; the supernatant of PACT pool 3 is introduced into ammonia nitrogen aerated biosorption filter 4, and ammonia nitrogen is absorbed by the natural After adsorption by 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 pool 5 for storage. At the same time, add nitrifying bacteria to the ammonia nitrog...
