Problems solved by technology

[0004] However, the composition of black and odorous water in rivers is complex. Not only is the content of COD high, but ammonia nitrogen, total nitrogen, total phosphorus and metal ions are also seriously exceeding the standard. Moreover, the types of pollutants in black and odorous water in different rivers are also different. It is difficult for the microecological preparations made by strains or a certain type of strains to be universal for different river black and odorous water

preparation example Construction

[0018] The embodiment of the present invention provides a method for preparing a composite microecological preparation for treating black and odorous water in river courses, which is used to prepare the above-mentioned composite microecological preparation, comprising the following steps:

[0019] According to the mass ratio of photosynthetic bacteria: nitrifying bacteria: denitrifying bacteria: Bacillus subtilis: Lactobacillus acidophilus: Candida utilis: actinomycetes is 2:2:1:1:1:1:2 Take photosynthetic bacteria respectively , nitrifying bacteria, denitrifying bacteria, Bacillus subtilis, Lactobacillus acidophilus, Candida utilis and actinomycetes, the photosynthetic bacteria, nitrifying bacteria, denitrifying bacteria, Bacillus subtilis, Lactobacillus acidophilus, producing Candida prion and actinomycetes are compounded and mixed uniformly to obtain the compound microecological preparation.

[0020] In the above-mentioned preparation method, the photosynthetic bacteria use...

Embodiment 1

[0046] The present embodiment provides a kind of composite micro-ecological preparation that is used for the treatment of river black and smelly water, and its active ingredient (by mass ratio) is: photosynthetic bacteria: nitrifying bacteria: denitrifying bacteria: Bacillus subtilis: Lactobacillus acidophilus: urin Candida: Actinomyces = 2:2:1:1:1:1:2. Concrete preparation steps are as follows:

[0047] Preparation of photosynthetic bacteria:

[0048] a1. Preparation of seed solution: pick a single colony of purified photosynthetic bacteria, inoculate it into a liquid medium, and incubate for 72 hours at 30°C, 200r / min, and light intensity 3000 1x to obtain a seed solution.

[0049] The culture medium is a mixed solution prepared in the following proportions: ammonium chloride 1g / L, sodium acetate 3.5g / L, magnesium chloride 0.1g / L, calcium chloride 0.1g / L, potassium dihydrogen phosphate 0.6g / L , dipotassium hydrogen phosphate 0.4g / L, yeast extract 0.1g / L, pH 7.5-8.0, steril...

Embodiment 2

[0079] The composite microecological preparation that the embodiment of the present invention makes is applied to a certain river course that needs to be controlled in Tianjin, selects part of the river section, and adopts soft enclosure to isolate a 50m 2 In the closed area, the compound micro-ecological preparation is splashed in this area, and the spraying concentration is 10g / m 2 , splashing once every two days. Observe the changes in water quality and take water samples every two days for testing. It is known from the experimental results that after adding the compound probiotics, the phenomenon of black odor was significantly weakened on the 6th day, and the water quality transparency was improved. After 14 days, the removal rates of COD, ammonia nitrogen, and sulfide in the water body were 86.56%, 80.38% and 77.11% (see the treatment effect figure 1 ).

Abstract

The invention discloses a compound microecological preparation for treatment of black and smelly water of river ways and a preparing method thereof. The compound microecological preparation consists of photosynthetic bacteria, nitrifying bacteria, denitrifying bacteria, bacillus subtilis, lactobacillus acidophilus, candida utilis and actinomycetes, and the mass ratio of photosynthetic bacteria tonitrifying bacteria to denitrifying bacteria to bacillus subtilis to lactobacillus acidophilus to candida utilis to actinomycetes is 2 to 2 to 1 to 1 to 1 to 1 to 2. The compound microecological preparation contains a great variety of microorganisms, has complete function, can effectively degrade main pollutants such as COD, ammonia nitrogen, sulfides and the like in the black and smelly water, improves the water quality, repairs a river way ecosystem, can be applied to black and smelly water of most river ways, and has a certain generality on control of black and smelly water of different river ways.

Description

technical field [0001] The invention belongs to the field of microbial treatment of sewage, and in particular relates to a compound microbial preparation for treating black and odorous water in river courses and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of my country's economy, a large amount of urban domestic sewage and industrial waste liquid have been discharged, and the accumulation of excess organic matter has exceeded the carrying capacity of some rivers, resulting in eutrophication of river water, imbalance of dissolved oxygen, and a large number of anaerobic microorganisms. It produces malodorous gases such as ammonia and hydrogen sulfide, and black substances such as ferrous sulfide and manganese sulfide, and the water body begins to appear black and odorous. The black and smelly river water not only affects the image of the city, but also causes great harm to the quality of buildings along the river and t...
