Abstract

A biologic deodoring system for sewage and chemical odor is composed of upper and lower reactors, sprinkling cylinder, the isolating layers at both ends of said both reactor, filler in both reactor, water circulator with two sprinklers, and gas inlet and exhaust unit. Its method includes such steps as culturing active sludge, preparing film, starting system and adding circulated liquid. Its advantages are high efficiency, no blocking and small size.

Description

Technical field: [0001] The invention relates to a biological treatment system and method for sewage and chemical odor. Background technique: [0002] At present, the main methods of controlling malodorous gas are physical method, chemical method and biological method. Physicochemical methods are effective in deodorization and odor control, and have the advantages of short reaction time and large processing capacity, but there are problems such as numerous equipment, complicated process, difficult regeneration of secondary pollution, complicated post-treatment process, and high energy consumption. Therefore, since the 1950s, foreign countries have devoted themselves to using biological oxidation methods to deal with odorous substances. The biological method uses microorganisms to decompose odorous substances, which requires simple equipment, low energy consumption, and convenient management and maintenance. It has become an important development direction for odor control a...
