Embodiment 1

[0030] Collect the waste water of a flavor enterprise, after testing, the waste water of this enterprise does not reach the discharge standard, and it needs to be treated before being discharged. The waste water of the above-mentioned enterprise is treated by using the waste water treatment agent and the waste water treatment method of the present invention. The specific steps are as follows:

[0031] Essence production waste water treatment method, comprises the following steps:

[0032] (1) Filtration: use grid sieve;

[0033] (2) Precipitation: In the precipitation step, add the following physical water purifiers in parts by weight, activated carbon is 3, organically modified zeolite is 3 and polyacrylamide 3; stir while adding, the stirring speed is 15r / min; stir After uniformity, let it stand for 2.5 hours; the physical water purifying agent is 0.008% of the total weight of waste water;

[0034] (3) Activated sludge method processes the waste water in the step (2), puts ...

Embodiment 2

[0042] Essence production waste water treatment method, comprises the following steps:

[0043] (1) Filtration: use grid sieve;

[0044] (2) Precipitation: In the precipitation step, add the following physical water purifiers in parts by weight, 1 for activated carbon, 1 for organically modified zeolite and 1 for polyacrylamide; stir while adding, and the stirring speed is 10r / min; After uniformity, let it stand for 1 hour; the physical water purifying agent is 0.005% of the total weight of waste water;

[0045] (3) The activated sludge method processes the waste water in the step (2), puts the waste water in the step (2) into the aeration tank, adds the activated sludge containing the compound microbial bacterial agent in the aeration tank, and then the activated sludge Put the mud into the aeration tank;

[0046] In the activated sludge, the composite microbial bacterial agent is: 0.02 of paracoccus ammonophilus bacterial powder, 0.05 of rhodococcus bacterial powder, 0.05 ...

Embodiment 3

[0049] Essence production waste water treatment method, comprises the following steps:

[0050] (1) Filtration: use grid sieve;

[0051] (2) Precipitation: In the precipitation step, add the following physical water purifiers in parts by weight, 5 for activated carbon, 5 for organically modified zeolite and 5 for polyacrylamide; stir while adding, and the stirring speed is 20r / min; Stand still for 4 hours after being uniform; the physical water purifying agent is 0.02% of the total weight of waste water;

[0052] (3) The activated sludge method processes the waste water in the step (2), puts the waste water in the step (2) into the aeration tank, adds the activated sludge containing the compound microbial bacterial agent in the aeration tank, and then the activated sludge Put the mud into the aeration tank;

[0053]In the activated sludge, the composite microbial bacterial agent is: 0.1 of paracoccus ammonophagus powder, 0.2 of rhodococcus bacterial powder, 0.2 of sulfate re...

Abstract

The invention belongs to the field of treatment of wastewater in food enterprises and in particular relates to an essence production wastewater treating agent and also relates to an essence production wastewater treatment method. The essence production wastewater treating agent comprises the following components in parts by weight: a physical water purifying agent, a compound microbial agent and an enzymic preparation, wherein the physical water purifying agent comprises 1-5 parts of activated carbon, 1-5 parts of organically modified zeolite and 1-5 parts of polyacrylamide; the compound microbial agent comprises 0.02-0.1 part of paracoccus aminovorans powder, 0.05-0.2 part of rhodococcus ruber powder, 0.05-0.2 part of sulfate reducing bacteria powder and 0.04-0.2 part of moraxella powder; and the enzymic preparation comprises 0.05-0.1 part of xylanase, 0.04-0.09 part of lignan hydroxylase and 0.01-0.06 part of laccase. By adopting the wastewater treating agent and the wastewater treatment method, complex large-particle organic matters difficult to degrade are hydrolyzed into simple organic matters easy to degrade, thus greatly reducing the content of SS (suspended substance) in the wastewater, and the treated wastewater has high BOD (biochemical oxygen demand) and COD (chemical oxygen demand) removal rates and reaches the specified discharge standard.

Description

technical field [0001] The invention belongs to the field of waste water treatment of food enterprises, and in particular relates to an essence production waste water treatment agent, and also relates to the above-mentioned essence production waste water treatment method. Background technique [0002] Fragrance is closely related to people's life. In the past ten years, China's fragrance industry has developed rapidly, with an annual output value of tens of billions of yuan and thousands of enterprises. The resulting environmental problems are becoming more and more serious. The composition of fragrance wastewater is complex and changeable. Some Wastewater has a high concentration of organic matter, is difficult to biodegrade, has high acidity, alkalinity and salt content, and also contains oil or surfactants, making it difficult to treat. [0003] The organic components of wastewater contain a large amount of aromatic hydrocarbons, aromatic compounds and their derivatives, ...
