Embodiment Construction

[0029] Such as figure 2 The shown two-stage biological waste gas treatment system has a first-stage biofilter 7 and a second-stage biofilter 10 . There is a first-stage biofilter bed layer 5 in the first-stage biofilter 7, and there are active biological strains in the first-stage biofilter bed layer 5, and wherein the thiophage species are the most active; the second-stage biofilter 10 There is a second-stage biological filter bed layer 14 in the middle, and the second-stage biological filter bed layer 14 has active biological strains, wherein the non-sulfur bacterial strains are more active.

[0030] Exhaust gas enters from the first-stage biofilter 7, is filtered, degraded or oxidized by the first-stage biofilter bed layer 5, and then flows out from the first-stage gas outlet pipeline, then flows through the second-stage biofilter 10, and passes through the second-stage biofilter 10. The first-stage biological filter bed layer 14 is filtered, degraded or oxidized and flow...

Abstract

The invention discloses a two-stage biological process waste gas treatment system, which is provided with a first-stage biological filter tank and a second-stage biological filter tank. The first-stage biological filter tank is provided with a first-stage biological filter bed layer; the first-stage biological filter bed layer contains the most active thiophilic bacteria in the largest amount, and the second-stage biological filter tank contains more non-sulfur bacteria. The first-stage biological filter tank is provided with a first-stage circulating water tank at the bottom, and the water solution has a pH value of 2-4; and the second-stage biological filter tank is provided with a second-stage circulating water tank at the bottom, and the water solution has the pH value of 5-8. A gas demister is arranged between the first-stage biological filter tank and the second-stage biological filter tank. The invention adopts two-stage biological treatment process, so that different exhaust gases respectively get appropriate treatment pointedly. The system has good purification effect, makes it easy for different microorganisms to survive and to always maintain good activity, and also has good self-control performance.

Description

technical field [0001] The invention relates to a waste gas treatment device and a treatment process method thereof. Background technique [0002] Exhaust gas treatment methods include filtration, adsorption, ozone oxidation, Shenwu decomposition, etc., but for some mixed gas exhaust gases, the traditional treatment methods are not thorough enough. [0003] The invention with the patent application number 2010102549848 discloses a high-activity biological waste gas purification tower, which includes a tower body. The top of the tower body is provided with a clean air outlet, and the bottom is provided with a water tank and an exhaust gas inlet. The side of the water tank is the main control system. There are upper, middle and lower layers, the upper layer is the aerosol separation layer, the middle layer is the biologically active exhaust gas washing layer, and the lower layer is the ultrafine atomization purification layer, wherein the positions of the biologically active e...
