Problems solved by technology

[0002] A large number of municipal sewage treatment plants have been built in my country since the 1990s, and most of the mainstream methods used are traditional activated sludge methods such as oxidation ditch, A / O, A 2 / O, etc. These methods have high energy consumption, complicated operation and management, and their treatment process is relatively simple, which cannot effectively cope with the impact of water quality and quantity changes and harsh weather. At the same time, these processes will produce activated sludge that is difficult to dispose of with current technologies.

Embodiment 2

[0064] Please also refer to figure 1 As shown, this embodiment provides a sequential batch adsorption aeration filter and land infiltration-constructed wetland coupling device, which includes: concentration pool 1, WAR reactor 2, heat exchanger 10, PACT pool 3, ammonia nitrogen aeration Gas biosorption filter 4, sewage return pool 5, deep phosphorus adsorption filter 7, land infiltration 8 and constructed wetland 9; 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 return pool 5 and the deep phosphorus adsorption filter 7, the deep phosphorus adsorption filter 7 is connected to the land infiltration 8, and the land infiltration 8 is...

Embodiment 3

[0084] Adopt the device described in embodiment 1 to carry out sewage treatment.

[0085] 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...

Abstract

The invention discloses a sequential batch type adsorption aeration filter tank and land infiltration-artificial wetland coupling device and its application in sewage treatment. The device includes: a concentration pond, a WAR reactor, a heat exchanger, a PACT pond, an ammonia nitrogen aerated biosorption filter, a sewage return pond, a deep phosphorus adsorption filter, land infiltration and an artificial wetland; wherein, the concentration pond Connect the WAR reactor, the WAR reactor is connected to the heat exchanger, the heat exchanger is connected to the PACT pool, and the PACT pool is respectively connected to the concentration pool and the ammonia nitrogen aerated biosorption filter , the ammonia nitrogen aerated biosorption filter is respectively connected to the sewage return tank and the deep phosphorus adsorption filter, the deep phosphorus adsorption filter is connected to the land infiltration, and the land infiltration is connected to the Artificial wetland. The device can remove pollutants in sewage, greatly reduce energy consumption and cost in the treatment process, and better complete the process of resource regeneration.

Description

technical field [0001] The invention relates to a sequential batch adsorption aeration filter tank and land infiltration-constructed wetland coupling device, in particular to a device for advanced sewage treatment which combines physical adsorption, biofilm method and land system. The present invention also relates to the application of the device in sewage treatment, that is, the method for treating sewage with the above-mentioned device. Background technique [0002] A large number of municipal sewage treatment plants have been built in my country since the 1990s, and most of the mainstream methods used are traditional activated sludge methods such as oxidation ditch, A / O, A 2 / O, etc. These methods have high energy consumption, complex operation and management, and relatively single treatment process, which cannot effectively cope with the impact of water quality and quantity changes and harsh weather. At the same time, these processes will produce activated sludge that i...
