Embodiment 1

[0037]This embodiment is basically as attached figure 1 Shown: a sewage treatment active microbial activation expansion system, including the main body of the reactor, the main body of the reactor includes a sedimentation tank, a primary activation tank and a secondary activation tank, the size of the sedimentation tank is 300*300*1200mm; the primary activation The size of the pool is 300*500*1200mm; the size of the secondary activation pool is 800*900*500mm.

[0038] The main body of the reactor is also equipped with a monitoring probe, a heating and heat preservation device, a refrigeration device, an aeration device, a storage tank, a dosing device and a single-chip microcomputer control system.

[0039] The pipeline connection mode of the first-level activation tank and the second-level activation tank is connected in series or in parallel. In the river channel; the parallel connection mode is that the river water passes through the pump to the sedimentation tank, overflo...

experiment example

[0047] Experimental example: water quality improvement experiment with different treatment methods

[0048] Test design:

[0049] Control group: The traditional way of directly pouring microbial activation culture solution (purchased from: Hengda Biotechnology Co., Ltd.) into the river is used to improve the water quality of the river, and the dosage refers to the instructions for use.

[0050] Experimental group: the water quality of the river course is improved by adopting the native microorganism expansion cultivation method of the present invention. Culture conditions: the first-level activation pool and the second-level activation pool are connected in parallel, the first-level activation pool: temperature 30°C, DO 5.5mg / L, pH 5.5-6.5, hydraulic retention time 12h, control the activation pool after adding nutrients Concentration: KH 2 PO 4 0.5g / L, K 2 HPO 4 0.5g / L, NH 4 Ac is 2.0g / L, NaS is 0.25g / L, yeast powder is 1g / L, and glucose is 2.0g / L. Secondary activation ...

Abstract

The invention relates to the field of sewage treatment, and discloses an activating and expanding culture system for sewage treatment active microorganisms. The system comprises a reactor main body, the reactor main body comprises a sedimentation tank, a primary activation tank and a secondary activation tank, the reactor main body is also provided with a monitoring probe, a heating and heat preservation device, a refrigeration device, an aeration device, a material storage tank, a feeding device and a single chip microcomputer control system; the monitoring probes are arranged in the first-stage activation tank and the second-stage activation tank and are used for monitoring temperature, dissolved oxygen and pH (Potential of Hydrogen); starting and stopping of the heating insulation device and the refrigeration device are adjusted by temperature parameter feedback; the aeration device is mounted at the bottoms of the primary activation tank and the secondary activation tank, and the start and stop of the aeration devices are adjusted by dissolved oxygen parameters; the storage tank is mounted at the tops of the first-stage activation tank and the second-stage activation tank; and the feeding device is arranged among the storage tank, the primary activation tank and the secondary activation tank. According to the invention, effective enrichment and proliferation of target microorganisms are realized through automatic adjustment of expanding culture conditions.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment active microorganism activation and expansion system and an activation and expansion method. Background technique [0002] According to the "Guidelines for the Remediation of Urban Black and Odorous Waters" issued by the Ministry of Housing and Urban-Rural Development, urban black and odorous waters refer to those in urban built-up areas that present unpleasant colors (black or pan-black) and / or radiate irritating odors. A general term for bodies of water that have an unpleasant smell (smelly or foul smell) for humans. The mechanism of water blackening is mainly divided into two types: one is insoluble substances existing in the water body in the form of solid or adsorbed on suspended particles; the other is colored humic organic compounds soluble in water. Through the research, it is found that the humic acid and fulvic acid in the suspended particles in the w...
