Embodiment 1

[0019] The method for processing chemical sewage with Klebsiella pneumoniae of the present invention comprises the following steps:

[0020] A bacterial carrier of hollow plastic balls is set in the bioreactor, and Klebsiella pneumoniae is adsorbed on it; then, chemical sewage is added into the bioreactor. At this time, the concentration of Klebsiella pneumoniae in the bioreactor is 10 billion per milliliter, the treatment time is 72 hours, and the treatment temperature is 33 degrees Celsius.

[0021] The chemical wastewater discharged from the bioreactor treatment has reached the standard of first-class industrial water.

Embodiment 2

[0023] The method for processing chemical sewage with Klebsiella pneumoniae of the present invention comprises the following steps:

[0024] A bacterial carrier of diatomite is set in the bioreactor, and Klebsiella pneumoniae is adsorbed on it; then, chemical sewage is added into the bioreactor. At this time, the concentration of Klebsiella pneumoniae in the bioreactor was 10 8 100 million per milliliter, the processing time is 0.5 hours. The processing temperature is 37 degrees Celsius.

[0025] The chemical wastewater discharged from the bioreactor treatment has reached the standard of first-class industrial water.

Embodiment 3

[0027] The method for processing chemical sewage with Klebsiella pneumoniae of the present invention comprises the following steps:

[0028] A bacterial carrier of porous bricks is set in the bioreactor, and Klebsiella pneumoniae is adsorbed on it; then, chemical sewage is added into the bioreactor. At this time, the concentration of Klebsiella pneumoniae in the bioreactor was 10 5 100 million per milliliter, the processing time is 30 hours. The processing temperature is 35 degrees Celsius.

[0029] The chemical wastewater discharged from the bioreactor treatment has reached the standard of first-class industrial water.

[0030] In other specific implementations, if the concentration of Klebsiella pneumoniae in the bioreactor is higher, the treatment time for treating chemical sewage into primary industrial water is less; the bacterial carrier can also be quartz sand, Activated carbon, polyurethane foam, macroporous resin or porous ceramics; in addition, the treatment time ...

Abstract

The invention relates to a method for treating chemical industrial sewage with klebsiella pneumonia. The method comprises the following steps: arranging a bacterial carrier in a bioreactor so that klebsiella pneumoniae is adsorbed on the bacterial carrier; adding the chemical industrial sewage inside a bioreactor so that the concentration of klebsiella pneumoniae is 10.2 billion-10.8 billion per milliliter; and treating the chemical industrial sewage inside the bioreactor for 0.5-72 hours. According to the method of treating chemical industrial sewage with klebsiella pneumoniae, the organic pollutants in the chemical industrial sewage are decomposed with klebsiella pneumoniae, the chemical industrial sewage is efficiently treated and the treated drainage water can reach the industrial water standard.

Description

technical field [0001] The invention relates to the technical field of chemical waste liquid treatment, in particular to a method for treating chemical sewage with Klebsiella pneumoniae. Background technique [0002] Paper industry wastewater is a typical chemical wastewater containing refractory organic compounds. The organic pollutants include: phenol, 2-methylphenol, 3-methylphenol, 2-ethylphenol, 2,5-dimethylphenol, 3-ethylphenol, 2-methyl-1,3 -benzenediol, 4-ethyl-1,3-benzenediol and the like. [0003] In China, the paper industry is a highly polluting industry. There are more than 700 papermaking enterprises in a certain province in China at most, 80% of which are wheat straw pulping enterprises with serious pollution. According to statistics, the province's paper industry accounts for more than 50% of the province's industry, whether it is new water consumption or COD emissions. The national standard for papermaking wastewater is 450mg / L CODer. There are many sew...
