Sequencing batch adsorption aerating filter and slow rate soil infiltration tank coupling device and application thereof

Abstract

The invention discloses a sequencing batch adsorption aerating filter and slow rate soil infiltration tank coupling device and an application thereof to sewage treatment. The device comprises a concentration tank, a WAR (wet air regeneration) reactor, a heat exchanger, a PACT (powdered activated carbon treatment) tank, ammonia nitrogen aeration biosorption filters, a sewage return tank, a sewage denitrification tank, a deep phosphorus adsorption filter and a slow rate soil infiltration tank, wherein the concentration tank is connected with the WAR reactor; the WAR reactor is connected with the heat exchanger; the heat exchanger is connected with the PACT tank; the PACT tank is connected with the concentration tank and the ammonia nitrogen aeration biosorption filters; the ammonia nitrogen aeration biosorption filters are connected with the sewage return tank, the sewage denitrification tank and the deep phosphorus adsorption filter; the deep phosphorus adsorption filter is connected with the slow rate soil infiltration tank. The device can achieve the effects of removing pollutants in sewage, substantially reducing energy consumption and cost in the treatment process and better completing the resource regeneration process.

Description

technical field [0001] The invention relates to a coupling device of a sequence batch adsorption aeration filter tank and slow soil infiltration, in particular to a device for advanced treatment of sewage combining physical adsorption, biofilm method and slow soil infiltration. 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] In the past 20 years, my country's domestic sewage treatment technology has made great progress. In municipal sewage treatment, nitrogen and phosphorus removal is generally taken as the main goal. In order to achieve the goal of simultaneous nitrogen and phosphorus removal, activated sludge method Based on the development of a large number of related processes 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 are...

[0002] In the past 20 years, my country's domestic sewage treatment technology has made great progress. In municipal sewage treatment, nitrogen and phosphorus removal is generally taken as the main goal. In order to achieve the goal of simultaneous nitrogen and phosphorus removal, activated sludge method Based on the development of a large number of related processes 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, low resistance to low temperature, troubled by filamentous expansion, not only complicated management , will also produce a large amount of activated sludge. At the same time, some processes require external carbon source addition and chemical reagents to remove phosphorus, which greatly increases the cost of the process, which greatly limits the promotion and use of these processes in vast areas of our country.
