Water-treatment composite microbe continuous culture device and culture method thereof

Abstract

The invention discloses a water-treatment composite microbe continuous culture device and a culture method thereof. The device comprises a tank (1), the tank (1) is separated into four independent culture zones comprising an aerobic zone (3), an anaerobic zone (4), a first transition zone (5) and a second transition zone (6) by separation plates (2), the first transition zone (5) and the second transition zone (6) are positioned between the aerobic zone (3) and the anaerobic zone (4), each of the culture zones is provided with a culture medium inlet (7) and an overflow mouth (8), a culture medium is continuously charged through the culture medium inlet (7), and a cultured bacterial liquid flows to a sewage treatment zone from the overflow mouth (8). The device and the method have the advantages of realization of the simultaneous and continuous culture of a plurality of strains, automatic addition of the culture medium, automatic charging of the bacterial liquid, improvement of the culture efficiency of the bacterial liquid, substantial acceleration of the composite pollution treatment speed, and avoiding of the sewage-treatment intermittent interruption caused by intermittent culture.

Description

technical field [0001] The invention relates to the field of water body purification, in particular to a water treatment compound microorganism continuous culture device and a culture method for compound pollution. Background technique [0002] Microbial decomposition treatment is a common method for water pollution. Before microbial decomposition treatment, microbial cultivation is required. However, in the process of water treatment, it is often necessary to use various types of bacteria, such as anaerobic bacteria and aerobic bacteria. In the prior art, different tanks are often used to culture various types of bacteria separately, but the cost of separate culture is relatively high, and it is inconvenient to fill the culture medium and put the cultured bacteria solution. In addition, the existing technology adopts a single culture and a single delivery when cultivating microorganisms. For example, 1 ton of culture medium is injected into the tank for cultivation. In th...

Problems solved by technology

The best way to deal with water pollution is continuous and uninterrupted. Intermittent cultivation and feeding of bacterial liquid are obviously not conducive to the treatment of water pollution. At the same time, the cultivation efficiency of the above bacterial liquid cultivation methods is low, and workers are required to be on duty and regularly add medium and Bacterial solution is put in, resulting in low water pollution treatment capacity and poor effect
