Embodiment Construction

[0016] In order to better understand the particle strengthening method for expanding and upgrading the existing sewage treatment system, the method will be described below in conjunction with examples.

[0017] In one embodiment, the present invention discloses a particle strengthening method for expanding and improving the existing sewage treatment system, including:

[0018] Adding solid particles to all of the existing one or more biological reaction zones or a partial area of ​​the reaction zone in the sewage treatment system;

[0019] Gas flow is used to suspend particles, and the suspended particle system includes carrier particles as microorganisms, and the principle of the suspended particle system is to facilitate the growth of microorganisms.

[0020] The biological reaction zone includes any one of facultative oxygen zone, anaerobic zone, anoxic zone, aerobic zone or a combination thereof.

[0021] For this embodiment, in the sewage treatment system, solid particle...

Abstract

The invention provides a particle strengthening method for capacity expanding and upgrading of an existing sewage treatment system. The particle strengthening method comprises the steps: adding solidparticles into all of one or more existing biological reaction regions or local regions of the reaction regions in the sewage treatment system; and suspending the particles by virtue of gas flowing toform a suspended particle system, wherein the suspended particle system comprises particles serving as carriers of micropopulations, and the suspended particle system is based on the principle of benefit for the growth of the micropopulations. When the suspended particle system is applied to sewage treatment, the concentrations of microorganisms can be greatly increased, the impact-resistant loadcan be improved, and the yield of residual sludge is low; in addition, due to the action of gases, a particle suspension way can realize great reduction of energy consumption. Therefore, the method for forming the suspended particle system by adding the solid particles can be used for effectively realizing capacity expanding and upgrading of the existing sewage treatment system and improving thesewage treatment capacity and effect.
