Description

Technical Field

[0001] The utility model relates to the technical field of microorganism cultivation, in particular to a modular movable microorganism expansion and cultivation device. Background Art

[0002] With the development of society, environmental pollution is becoming increasingly serious, especially the seriously polluted oilfield wastewater. At present, the method of decomposing pollutants in oilfield wastewater by proliferating and expanding the cultivation of oil recovery functional microorganisms has been widely used. Microorganisms can effectively decompose various complex organic substances, thus playing an important role in soil remediation, water body management, and solid waste treatment. The bioremediation technology that uses microorganisms to decompose harmful and toxic substances is considered to be a valuable method for treating large areas of pollution.

[0003] In the prior art, the patent with publication number CN105776772A discloses a modular movable microbial expansion device, including an oil removal tank, a primary biological expansion tank, a secondary biological expansion tank, a tertiary biological expansion tank, a high-efficiency sedimentation tank, and a water outlet tank. The oil removal tank is provided with an oil overflow port, and the oil removal tank is connected to the primary biological expansion tank, the secondary biological expansion tank, and the tertiary biological expansion tank in sequence. The internal structures of the primary biological expansion tank, the secondary biological expansion tank, and the tertiary biological expansion tank are the same. The tertiary biological expansion tank is also connected to the high-efficiency sedimentation tank, and the high-efficiency sedimentation tank is connected to a water outlet tank. A plurality of oil-resistant and anti-clogging aeration heads are installed at the bottom of the primary biological expansion tank, and the plurality of aeration heads are connected to each other. A packing bracket is installed above the plurality of aeration heads, and the packing bracket is filled with encrypted biological packing, and an oil-isolating baffle is arranged above the packing bracket. An adjustable water collection weir and an oil-repelling inclined plate are arranged on the inner side of the high-efficiency sedimentation tank, and the adjustable water collection weir is placed above the oil-repelling inclined plate.

The above-mentioned devices generally place microorganisms directly into the propagation pool. The concentrations of microorganisms and propagation liquid are relatively uneven, and factors such as temperature and oxygen content in the water in the propagation pool are relatively unstable, which can easily lead to poor microbial propagation effects, thereby causing the microorganisms to have a less than ideal treatment effect on river water bodies.
