Description

A sewage treatment system for glycerine waste water

Technical Field

The utility model relates to a sewage treatment system for glycerine waste water.

Background

Glycerol is a common trihydric alcohol, is a viscous liquid without color and with sweet taste under common conditions, and has wide application value in the chemical industry of China. In the actual production of chemical products in China, the crude glycerol is usually purified by a method of first treatment and then reduced pressure distillation to prepare the glycerol with higher purity and the glycerol is used in the fields of cosmetics, foods and the like. In the purification process, a large amount of wastewater containing glycerol is generated, and if the wastewater is directly discharged into the environment, the ecological balance is destroyed.

At present, a treatment system special for treating glycerin-containing wastewater is not available, and the treatment effect of the glycerin wastewater is poor.

Therefore, there is a particular need for a sewage treatment system for glycerol wastewater that solves the problems of the prior art.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects in the prior art and providing a sewage treatment system for glycerol wastewater, which can effectively remove organic matters such as glycerol in sewage and has good glycerol wastewater treatment effect.

In order to achieve the above purpose, the technical scheme of the utility model is as follows:

a sewage treatment system for glycerol wastewater comprises a filter tank, a regulating tank, an anaerobic tank, an activated sludge tank, a contact oxidation tank and a sedimentation tank;

the filter tank, the adjusting tank, the anaerobic tank, the activated sludge tank, the contact oxidation tank and the sedimentation tank are sequentially communicated.

In order to further realize the utility model discloses, vertically be provided with the filtration grid in the filtration pond.

In order to further realize the utility model discloses, the income water end intercommunication of filtering ponds is provided with the catch basin.

In order to further realize the utility model discloses, the play water end intercommunication of sedimentation tank is provided with the tank.

Advantageous effects

The utility model discloses can effectively get rid of organic matter such as glycerine in the sewage, glycerine waste water treatment effect is good, satisfies "discharge criteria is synthesized to sewage" (GB89780-1996) one-level standard restriction, reduces environmental pollution.

Drawings

FIG. 1 is a schematic view of the wastewater treatment system for glycerin wastewater of the present invention.

Description of reference numerals:

1. a water collecting tank; 2. a filtration tank; 3. a regulating tank; 4. an anaerobic tank; 5. an activated sludge tank; 6. a contact oxidation pond; 7. a sedimentation tank; 8. a water storage tank.

Detailed Description

The invention will be described in further detail with reference to the accompanying drawings, which are simplified schematic drawings and only schematically illustrate the basic structure of the invention.

As shown in figure 1, the utility model discloses a sewage treatment system for glycerine waste water includes catch basin 1, filtering ponds 2, equalizing basin 3, anaerobism pond 4, activated sludge pond 5, contact oxidation pond 6, sedimentation tank 7 and tank 8, wherein:

the water collecting tank 1, the filtering tank 2, the regulating tank 3, the anaerobic tank 4, the activated sludge tank 5, the contact oxidation tank 6, the sedimentation tank 7 and the water storage tank 8 are sequentially communicated and arranged.

The water collecting tank 1 can buffer the inflow water volume of the glycerol wastewater, and the reduction of the sewage treatment effect caused by the overlarge burden of the system in the drainage peak period is avoided.

The filtering tank 2 is used for filtering particles in the glycerol wastewater, and a filtering grid is longitudinally arranged in the filtering tank.

Because the water quality and components of the glycerol sewage are unstable, the adjusting tank 3 is used for balancing the PH value of the glycerol wastewater and reducing the concentration of COD in the wastewater.

The anaerobic tank 4 is used for decomposing organic matters such as glycerin in the glycerin wastewater through anaerobic bacteria to primarily degrade the organic matters such as glycerin; the specific process is that organic matters such as glycerin and the like convert glycerin and organic pollutants into acid under the acidification and degradation action of anaerobic microorganisms, and partial organic acid is classified into methane gas under the action of methane bacteria and overflows.

The activated sludge tank 5 and the contact oxidation tank 6 can well take out organic matters such as glycerin in sewage through the action of oxygen-consuming bacteria, the activated sludge tank and the contact oxidation tank are connected in series, and the removal rate of the organic matters such as glycerin is high through the treatment of two stages of oxygen-consuming bacteria.

The sedimentation tank 7 can effectively take out suspended matters in the sewage, and the quality of the effluent is improved.

The water storage tank 8 is used for storing partial process reuse water, and water consumption in sewage treatment is reduced.

The above is only the preferred embodiment of the present invention, the present invention is not limited to the above embodiment, there may be local minor structural modification in the implementation process, if it is right that various modifications or variations of the present invention do not depart from the spirit and scope of the present invention, and belong to the claims and the equivalent technical scope of the present invention, then the present invention is also intended to include these modifications and variations.
