preparation example Construction

[0045] Another specific embodiment of the present invention provides the preparation method of the composite microbial bacterial agent, comprising: uniformly mixing the composite microbial bacterial agent and amino polysaccharide chelate salt to obtain the composite microbial bacterial agent.

[0046] Yet another specific embodiment of the present invention provides the application of the composite microbial agent in improving the pollution of water body sediment. The composite microbial bacterial agent has a small amount of addition in the water body, and can obtain a good effect of purifying the bottom mud. The amount of the composite microbial agent added to the water body is preferably 3-8ppm, more preferably 5-8ppm, and most preferably 5ppm.

Embodiment 1

[0049] 10 parts by weight of amino polysaccharide chelate salt and 90 parts by weight of composite microorganisms composed of lactic acid bacteria, saccharomyces, actinomycetes and filamentous bacteria are uniformly mixed to make microbial bacterial agent 1 for improving water body sediment.

[0050] The method of the compound microorganism that above-mentioned lactic acid bacteria, saccharomycetes, actinomycetes, filamentous fungus are formed comprises the steps:

[0051] Collect 1.0 g of sediment from seriously polluted water bodies, put it into a 50 mL Erlenmeyer flask filled with 9 mL of sterile water and glass beads, shake it on a shaker for 20 minutes to disperse the microbial cells, and let it stand for 30 seconds. -1 Diluent; use a 1mL sterile pipette to draw 10 -1 Dilute 1mL, transfer to a test tube filled with 9mL sterile water, suck and blow 3 times, mix the bacterial solution, and serve as 10 -2 Diluent. By analogy, serial dilutions were made to make 10 -3 、10 ...

Embodiment 2

[0053] Repeat Example 1, the difference is that amino polysaccharide chelated salt is 8 weight parts, and the composite microorganism that lactic acid bacteria, saccharomycete, actinomycetes, filamentous fungus is formed is 92 weight parts, makes the microbial bacterial agent that improves water body bottom mud 2.

Abstract

The invention discloses a composite microbial agent for improving water body bottom mud, which comprises the following components in parts by weight: 80-92 parts of a composite microbial agent and 8-20 parts of glycosaminoglycan chelate salt based on 100 parts of total weight. The composite microbial agent can well solve the degradation problem of water body bottom mud pollution indexes, and especially has the very good effect on bottom mud ecological restoration of polluted water bodies such as pollutant holding pits and ponds and riverways. The invention also discloses a preparation method and an application of the composite microbial agent.

Description

technical field [0001] The invention relates to the technical field of water treatment. More specifically, it relates to a composite microbial bacterial agent for improving water body sediment and its preparation method and application. Background technique [0002] The distribution of water resources in my country is uneven, with more in the south and less in the north. At the same time, there is an uneven distribution of water resources in different seasons. There is more rain in summer and autumn, and less rain in spring and winter. This leads to insufficient hydrodynamic force in water bodies such as urban rivers and lakes in the dry season, and a lot of domestic waste rich in organic pollutants is deposited. A large number of pollutants in these sediments are rich in nutrients such as nitrogen and phosphorus, which are continuously released into the water body and are an important source of water body pollution. Such pollutants ferment and deteriorate in water bodies,...
