preparation example Construction

[0019] The embodiment of the present invention provides a nitrifying bacteria bacterial agent and a preparation method thereof. The nitrifying bacteria agent is used for treating and converting ammonia nitrogen into nitro nitrogen. The bacterial agent includes: nitrifying bacteria (the Latin name is Nitrobacter winogradskyi) and nitrosifying bacteria (the Latin name is Nitrosomonas europaea), and the nitrifying bacteria and the nitrosifying bacteria are mixed in a weight ratio of 1:1 to 10:1 to form the Nitrifying bacteria agent.

[0020] It is also possible to add a stabilizer and strain protection agent in the nitrifying bacteria agent. The stabilizer can be any one of glycerin, ethanol, and ethylene glycol, and its consumption is 0.05 to 2% of the weight of the nitrifying bacteria agent; The protective agent can be any one of zeolite powder, diatomaceous earth, and powdered activated carbon, and its consumption is 0.1-1% of the weight of the nitrifying bacteria agent.

Embodiment 1

[0034]This embodiment 1 provides a nitrifying bacteria agent, which is used to treat the nitrifying bacteria agent that converts ammonia nitrogen into nitro nitrogen. The bacterial agent includes: nitrifying bacteria and nitrosobacteria, which are mixed in a weight ratio of 1:1 to form a nitrifying bacterial agent; wherein, the nitrifying bacteria can be named after common nitrifying bacteria, namely the Latin Nitrobacter winogradskyi The nitrifying bacteria; the nitrosifying bacteria can adopt the common nitrosifying bacteria, namely the nitrosifying bacteria named in Latin Nitrosomonas europaea. Nitrifying bacteria and nitrosifying bacteria can also be obtained by screening and domesticating the activated sludge through nitrifying bacteria cultivated under aerobic conditions. The description of the following preparation method can be referred to.

[0035] The preparation method of above-mentioned nitrifying bacteria bacterial agent is specifically as follows:

[0036] Get ...

Embodiment 2

[0041] This embodiment 2 provides a nitrifying bacteria agent, which is used to treat the nitrifying bacteria agent that converts ammonia nitrogen into nitro nitrogen. The bacteria agent comprises: nitrifying bacteria and nitrosifying bacteria, and the nitrifying bacteria and nitrosifying bacteria are mixed in a weight ratio of 5:1 to form the nitrifying bacteria agent.

[0042] The preparation method of above-mentioned nitrifying bacteria bacterial agent is specifically as follows:

[0043] Get the activated sludge in the aerobic tank, insert respectively the nitrifying bacteria enrichment medium (the nitrifying bacteria enrichment medium is: ammonium sulfate 2g, magnesium sulfate 0.5g, sodium chloride 0.5g, dipotassium hydrogen phosphate 0.5g, Ferrous sulfate 0.05g, calcium carbonate 1g and water 1000ml) and nitrosative bacteria enrichment medium (nitrosative bacteria enrichment medium: ammonium sulfate 0.5g, magnesium sulfate 0.2g, sodium chloride 0.4g, dipotassium hydrogen...

Abstract

The invention discloses a nitrifying bacterial agent and a preparation method thereof, which belong to methods for preparing the nitrifying bacterial agent. The nitrifying bacterial agent is used to treat and transform ammonia nitrogen into nitro-group nitrogen. The nitrifying bacterial agent comprises nitrobacteria and nitrosobacteria, wherein the nitrobacteria and the nitrosobacteria are mixed in a weight ratio of 1:1-10:1. The nitrifying bacterial agent can be used to treat wastewater with overhigh ammonia nitrogen content. By combining different processes, good treatment effect can be achieved.

Description

technical field [0001] The invention relates to the field of bacterial agent preparation, in particular to a nitrifying bacterial bacterial agent for converting ammonia nitrogen into nitro nitrogen and a preparation method thereof. Background technique [0002] Ammonia nitrogen is the most harmful pollution factor in water bodies. It will lead to eutrophication of rivers and lakes and weaken the self-purification ability of water bodies. Ammonia nitrogen in polluted water usually refers to nitrogen existing in the form of ammonia. Compared with other organic pollutants, the removal methods of ammonia nitrogen in polluted water mainly include physical, chemical and biological methods. Physical or chemical methods include air hair removal, breakpoint chlorination, ion exchange adsorption, flocculation precipitation, electrodialysis, catalytic wet oxidation, liquid membrane, etc. These methods are generally used for the pretreatment of high-concentration ammonia-nitrogen waste...
