Problems solved by technology

[0002] In recent years, with the improvement of my country's economic level, my country's municipal sewage treatment technology has also begun to innovate. The main traditional processes are all improved and strengthened with the activated sludge process as the core process, mainly including A 2 / O, SBR, CASS, etc. Although these methods can obtain good nitrogen and phosphorus removal effects, they all have the advantages of large area, high one-time investment, complicated process control, and a large amount of activated sludge. At the same time, some The process requires the addition of external carbon sources and the removal of phosphorus by chemical reagents, which greatly increases the cost of the process, which greatly limits the promotion and use of these processes in vast areas of our country. In order to achieve the goal of building an ecological civilization and scientific development in our country

Embodiment 1

[0045] Such as figure 1 As shown, the coupling device of the sequence batch adsorption aeration filter of the present invention and the constructed wetland-ecological pond includes: a concentration pond 1, a WAR reactor 2, a heat exchanger 10, a PACT pond 3, and an ammonia nitrogen aeration biosorption Filter 4, sewage reflux pool 5, sewage denitrification pool 6, deep phosphorus adsorption filter 7, constructed wetland 8 and ecological pond 9; wherein, the concentration pool 1 is connected to the WAR reactor 2, and the WAR reaction The device 2 is connected to the heat exchanger 10, and the heat exchanger 10 is connected to the PACT pool 3, and the PACT pool 3 is respectively connected to the concentration pool 1 and the ammonia nitrogen aerated biosorption filter 4, and the ammonia nitrogen The aerated biosorption filter 4 is respectively connected to the sewage return pool 5, the sewage denitrification tank 6 and the deep phosphorus adsorption filter 7, and the deep phospho...

Embodiment 2

[0065] Please also refer to figure 1 As shown, the coupling device of the sequencing batch adsorption aeration filter and the constructed wetland-ecological pond in this embodiment includes: a concentration pond 1, a WAR reactor 2, a heat exchanger 10, a PACT pond 3, and an ammonia nitrogen aerated organism Adsorption filter 4, sewage reflux pond 5, sewage denitrification pond 6, deep phosphorus adsorption filter 7, constructed wetland 8 and ecological pond 9; wherein, the concentration pond 1 is connected to the WAR reactor 2, and the WAR The reactor 2 is connected to the heat exchanger 10, the heat exchanger 10 is connected to the PACT pool 3, and the PACT pool 3 is respectively connected to the concentration pool 1 and the ammonia nitrogen aerated biosorption filter 4, the The ammonia nitrogen aerated biosorption filter 4 is respectively connected to the sewage return pool 5, the sewage denitrification tank 6 and the deep phosphorus adsorption filter 7, and the deep phospho...

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...

Abstract

The invention discloses an adsorptive aeration filter tank, artificial wetland and ecological pond coupling device and application thereof to wastewater treatment. The device comprises a concentration tank, a WAR (wet air regeneration) reactor, a heat exchanger, a PACT (powered activated carbon treatment) tank, a biological ammonia nitrogen adsorptive aeration filter tank, a wastewater backflow tank, a wastewater denitrification tank, a deep phosphorus adsorption filter tank, artificial wetland and an ecological pond. The concentration tank is connected with the WAR reactor which is connected with the heat exchanger, the heat exchanger is connected with the PACT tank which is connected with the concentration tank and the biological ammonia nitrogen adsorptive aeration filter tank, the biological ammonia nitrogen adsorptive aeration filter tank is connected with the wastewater backflow tank, the wastewater denitrification tank and the deep phosphorus adsorption filter tank, and the deep phosphorus adsorption filter tank is connected with the artificial wetland which is connected with the biological pond. The adsorptive aeration filter tank, artificial wetland and ecological pond coupling device and application thereof have the advantages that pollutant in wastewater can be removed, energy consumption and cost in a treatment process are greatly reduced, and a resource regeneration process is well completed.
