preparation example Construction

[0052] Further preferably, the preparation method of the aquatic plant endophyte composition comprises the following steps:

[0053] (1) Collection of aquatic plants;

[0054] (2) Mixing the above-mentioned raw materials and fermenting to obtain an aquatic plant endophyte composition.

[0055] In some embodiments, the picking method of the aquatic plants is: picking the green parts of the aquatic plants before sunrise.

[0056] In some embodiments, the specific operation of the step (2) is as follows: adding sucrose to the aquatic plants under aseptic conditions and stirring evenly, then adding non-iodized salt and brine and stirring until the aquatic plants have juice flowing out, under sealed conditions Incubate at a constant temperature and filter to obtain the liquid fraction.

[0057] Further, the conditions of the constant temperature culture are: constant temperature culture at 30 to 40° C. for 5 to 10 days.

[0058] A fourth aspect of the present disclosure provides...

Embodiment 1

[0064] The bacterial strain model used in the present embodiment and the purchase method are as follows:

[0065] The yeast is commercial yeast, and the brand is Angel high temperature resistant liquor yeast;

[0066] Lactobacillus Lactobacillus plantarum CICC 21790, purchased from Industrial Microorganisms Collection Center;

[0067] Bacillus natto is Bacillus natto, purchased from Cangzhou Laisen Biotechnology Co., Ltd.;

[0068] Bacillus subtilis is Bacillus subtilis subsp. subtilis GIM1.372, purchased from the Guangdong Provincial Microbial Culture Collection Center;

[0069] Bacillus licheniformis (Bacillus licheniformis) GIM1.626, purchased from Guangdong Provincial Microbial Culture Collection Center;

[0070] Photosynthetic Bacteria (PSB for short), purchased from Cangzhou Laisen Biotechnology Co., Ltd.;

[0071] The actinomycetes were Nocardia (Nocardia) GIM1.381, purchased from the Guangdong Provincial Microbial Culture Collection Center;

[0072] Nitrifying bact...

Embodiment 2

[0077] In this example, the effect of the compound bacterial agent in treating black and odorous river silt is described with the results of the pilot test of the ecological restoration of the black and odorous river silt in the Xiwangmen River in Rongcheng, Shandong. The tofu brine used in this embodiment is Angel Baizhuan brine tofu coagulant.

[0078] 1. Location and scope

[0079] like Figure 5 It is located within 100m under the bridge, and the average width of the river is about 50m. In order to emphasize the contrast effect of governance, the center line of the river is used as the boundary, and half of the river silt on the west side is selected for in-situ restoration.

[0080] 2. Pilot scheme

[0081] (1) Closing the gate to control tide, isolation and management

[0082] In order to avoid the impact of seawater tide on the construction, it is necessary to close the gate before construction to block the sea tide; due to the thick silt in the river, the silt aroun...

Abstract

The present disclosure belongs to the technical field of sewage treatment, and in particular relates to a composite microbial preparation for sewage treatment and its application. The inventor believes that the method of using foreign bacteria to treat polluted waters in the prior art has certain uncertainties. The present disclosure provides a composite flora with environmental microorganisms, basic microorganisms, and functional microorganisms recombined into a purifying function. . Further, the present disclosure also provides a microbial composition and an aquatic plant endophyte composition, the above-mentioned microbial combination can well achieve the reduction of silt in black and odorous rivers, and the combination of aquatic plant endophytes can effectively to reduce COD and NH in water 3 ‑N, TP, water chromaticity and odor, thereby improving the water quality of black and odorous water. The microorganism combination has a good application prospect in the field of sewage treatment.

Description

technical field [0001] The disclosure belongs to the technical field of sewage treatment, and in particular relates to a composite microbial inoculant, an aquatic plant endophytic inoculant and its application in sewage treatment. Background technique [0002] The disclosure of information in this Background section is only for enhancement of understanding of the general background of the disclosure and should not necessarily be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art. [0003] In the underdeveloped stage of urban industrialization, water sources in nature can rely on microorganisms to metabolize excretion wastes in the system to maintain ecological balance and keep water clean. With the expansion of human production, living areas and their scale, and the continuous improvement of industrialization, the amount of pollutants discharged has exceeded the inherent self-...
