Problems solved by technology

This method has a certain effect in a short period of time, but because the free bacteria are not easy to colonize in the water body, the activity is not high, they are easy to lose with the water flow, and they are easy to be preyed by higher organisms, the purification effect is not sustainable and stable

Embodiment 1

[0023] A fixed water purifying agent comprises a compound microbial preparation and an immobilized carrier.

[0024] The composite microbial bacterial agent is composed of heterotrophic nitrifying bacteria-Acinetobacter, Candida and Bacillus subtilis.

[0025] The preparation method of the composite microbial agent is as follows: respectively culturing Acinetobacter, Candida, and Bacillus subtilis to a concentration of 1×10 7 bacterium solution / ml, and then mixed according to the volume ratio of 3:1:2, to obtain final product;

[0026] The Acinetobacter SP. is ATCC NO.17978;

[0027] The Candida utilis (Candida utilis) ATCC NO.22023;

[0028] The Bacillus subtilis is (Bacillus subtilis) ATCC NO.6633

[0029] The immobilized carrier is composed of ceramsite and zeolite in a weight ratio of 1:1;

[0030] The immobilized carrier and the composite microbial agent were mixed at a volume ratio of 1:6, and cultured for 48 hours with aeration (stirring speed: 120rmp / Min) at 28°C t...

Embodiment 2

[0032] Example 2 An immobilized water purifier, which includes a composite microbial preparation and an immobilized carrier.

[0033] The composite microbial bacterial agent is composed of heterotrophic nitrifying bacteria-Acinetobacter, Candida and Bacillus subtilis.

[0034] The preparation method of the composite microbial agent is as follows: respectively culturing Acinetobacter, Candida, and Bacillus subtilis to a concentration of 1×10 7 bacterium solution / ml, then mix according to the volume ratio of 4:2:3, to obtain final product;

[0035] The Acinetobacter SP. is ATCC NO.17978;

[0036] The Candida utilis (Candida utilis) ATCC NO.22023;

[0037] The Bacillus subtilis is (Bacillus subtilis) ATCC NO.6633

[0038] The immobilized carrier is composed of ceramsite and zeolite in a weight ratio of 1:1;

[0039]The immobilized carrier and the composite microbial agent were mixed at a volume ratio of 1:7, and cultured for 48 hours with aeration (stirring speed: 120rmp / Min)...

Embodiment 3

[0041] Embodiment 3 The pathogenicity test of the water purifying agent of the present invention to water hyacinth:

[0042] (1) Preparation of compound microbial agent:

[0043] Experimental group: Acinetobacter, Candida, and Bacillus subtilis were cultured according to conventional culture methods to a concentration of 1×10 7 bacterium solution per ml, and then mixed according to the volume ratio of 3:1:2; the Acinetobacter SP. is ATCC NO.17978; the Candida utilis is ATCC NO.22023 ; The Bacillus subtilis is (Bacillus subtilis) ATCC NO.6633;

[0044] Control group 1: Acinetobacter and Candida were cultured according to conventional culture methods to a concentration of 1×10 7 Each / ml of the bacterial liquid, then mixed according to the volume ratio of 3:1; the Acinetobacter is ATCC NO.17978; the Candida is ATCC NO.22023;

[0045] Control experiment group 2: Candida and Bacillus subtilis were cultured according to conventional culture methods to a concentration of 1×10 7 B...

Abstract

The invention relates to a preparation method of immobilized water purifying agent, which comprises the following steps: mixing immobilized carrier and composite microbial agent according to a volumeratio of 1: (6-7), stirring and culturing at 28-30 DEG C for 36-48h. The composite microbial agent comprises of acinetobacter, candida mycoderma bacteria and bacillus subtilis. The water purifying agent can obviously reduce the COD value of the eutrophic water body and inhibit the large-scale growth of the water hyacinth, thereby having popularization value and wide application prospect.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a preparation method of an immobilized water purifying agent and its application for treating aquatic herbs. Background technique [0002] Water hyacinth (Eichhornia crassipes Solms) is a perennial aquatic herb of the genus Eichhornia crassipes, also known as water hyacinth, false narcissus, and foreign narcissus. It is native to South America and was introduced to my country in the 1930s. Promoted as livestock and poultry feed. Water hyacinth begins to reproduce at a temperature of 13°C, and can still reproduce at a temperature of 39°C. It has both asexual and sexual reproduction functions, especially asexual reproduction, and its population recovery and diffusion capabilities are extremely strong. Water hyacinth likes to be born in warm, sunny and still water rich in organic matter. Under suitable conditions, a new plant can be reproduced every 5 days, and the biomass can increase ...
