Abstract

The invention relates to equipment and method for online propagating and expand-culturing active floras in a sewage treatment system. A set of online propagating and expand-culturing device is mounted on an original sewage treatment system, and comprises a bacterium source feeding device, a nutrient solution supplying and mixing device, a light-transmitting propagating container unit and an oxygenation constant-temperature aerating device which are connected in sequence, the bacterium source feeding device is connected with a return sludge pipeline of the original sewage treatment system and used for introducing a bacterium source from the original sewage treatment system, a discharging pipeline of the light-transmitting propagating container unit is connected with a biochemical pool of the original sewage treatment system, and therefore flora multiplication liquid obtained through expand-culture is returned into the sewage treatment system. Online continuous fast expand-culture of the active floras is achieved, the microbial floras obtained through expand-culture do not need to be acclimated, and can directly adapt to the physicochemical indexes of sewage in the original sewage treatment system and fast participate in decomposition of organic pollutants in the sewage, and effective stability of the sewage treatment system is improved.

Description

technical field [0001] The invention relates to a method and equipment for expanding and cultivating microbial flora in sewage treatment, in particular to an equipment and method for on-line proliferation and expanding the active flora in a sewage treatment system. Background technique [0002] In the process of organic sewage treatment, the biologically activated sludge method is widely used because of its effective removal of organic pollutants. The biologically activated sludge method is based on the type of pollution source to select the applicable bacterial group to treat organic sewage. , It has strong adsorption and oxidation capabilities for organic matter, and high treatment efficiency. [0003] Maintaining the basic quantity of active bacteria in sewage is the key link to ensure the degradation efficiency of pollutants and the stability of sewage treatment system operation. Biologically active bacteria exist in the sludge of sewage treatment biochemical tanks and ...
