Embodiment 1

[0033] Embodiment 1 Certain black and smelly river course control project:

[0034]A black and odorous river course is a severe black and odorous water body, NH3-N 16mg / L, TP 100mg / L and COD130mg / L. In the process of treatment, more than 2 million yuan was spent to purchase an imported bacterial agent, and after 3 months of operation, the effect was still not obvious.

[0035] This project adopts a compound micro-ecological preparation for the treatment of black and odorous water in river pits and ponds according to this embodiment, including indigenous microorganisms with repairing functions, functional bacteria and carrier substrates isolated from the black and odorous water to be treated. The indigenous microorganisms are nitrifying bacteria, denitrifying bacteria and Bacillus subtilis, the functional bacteria are photosynthetic bacteria, Candida utilis, Bacillus megaterium, lactic acid bacteria, and actinomycetes, and the carrier matrix is ​​green zeolite. Black and odoro...

Embodiment 2

[0058] Example 2 A certain black and smelly pit pond treatment project

[0059] A black and smelly pond is a severe black and smelly water body, ammonia nitrogen 18.9mg / L, SS29.2mg / L, BOD57.1mg / L, DO1.9mg / L.

[0060] This project adopts a compound micro-ecological preparation for the treatment of black and odorous water in river pits and ponds according to this embodiment, including indigenous microorganisms with repairing functions, functional bacteria and carrier substrates isolated from the black and odorous water to be treated. The indigenous microorganisms are nitrifying bacteria, denitrifying bacteria and Bacillus subtilis, the functional bacteria are photosynthetic bacteria, Candida utilis, and Bacillus megaterium, the carrier matrix is ​​vermiculite, and the black and smelly water body includes black and smelly water Black and odorous surface water from rivers, lakes or polluted sites.

[0061] Further, the indigenous microorganisms are screened through the following ...

Embodiment 3

[0083] Example 3 Black and odorous surface water treatment project of a polluted site

[0084] During the restoration and treatment process of a polluted site, the black and odorous water remaining on the ground surface was seriously polluted, and the ammonia nitrogen reached 225mg / L. The water treatment facilities of this project had no obvious removal effect on ammonia nitrogen. Therefore, the method provided by the present invention was used for treatment. The specific implementation is as follows : This project adopts a kind of composite micro-ecological preparation for the treatment of black and odorous water in river pits and ponds of this embodiment, including indigenous microorganisms with repairing functions, functional bacteria and carrier substrates isolated from the black and odorous water to be treated, The indigenous microorganisms are nitrifying bacteria, denitrifying bacteria and Bacillus subtilis, the functional bacteria are photosynthetic bacteria, Bacillus me...

Abstract

The invention discloses a composite micro-ecological preparation for treating black stink water in rivers, pits and ponds and a preparation method thereof. The composite microbial preparation comprises indigenous microorganism, functional strain and carrier matrix which are separated from a black stink water body to be treated and have a repairing function. The indigenous microorganism is at leastone of nitrifying bacteria, denitrifying bacteria and bacillus subtilis, the functional strain is at least one of photosynthetic bacteria, candida utilis, bacillus megaterium, lactic acid bacteria and actinomycetes, and the carrier matrix is at least one of crocalite, green zeolite, ceramsite, quartz sand, vesuvianite and vermiculite. The black stink water body includes black stink surface waterof black stink rivers, black stink lakes or polluted ground. According to the invention, the composite micro-ecological preparation is formed by immobilizing the indigenous microorganism, the functional strain and the carrier matrix, has remarkable effects of degrading the pollutants such as COD, NH3-N, TP and the like in the black stink water. The preparation method disclosed by the invention haswide applicability to black stink surface water of various black stink rivers, black stink lakes or polluted ground.

Description

technical field [0001] The invention belongs to the field of microbial treatment for treating sewage, and in particular relates to a compound microecological preparation for treating black and odorous water in river channels, pits and ponds and a preparation method thereof. Background technique [0002] With the rapid development of economy, the continuous acceleration of urbanization process, and the sharp increase of urban population, urban rivers have been seriously polluted, the self-purification ability of water body has been declining, and black and odorous water bodies have appeared in large areas. Organic pollutants in water bodies such as sugar, Amino acids, proteins, oils, etc. are decomposed into small molecular substances, which consume a large amount of dissolved oxygen; inorganic pollutants such as AeS and MnS that are easily oxidized, cause the water body to be black; the concentration of ammonia nitrogen, sulfide, etc. increases, causing odor phenomena , Seri...
