Abstract

The invention discloses a kind of application of sodium acetate as sewage treatment plant's additional carbon, comprise the following steps：1）Trade effluent is adjusted into ph values in regulating reservoir, then the trade effluent adjusted after ph values is precipitated in sedimentation basin；2）Trade effluent after precipitation is delivered to microculture pond and carries out microbiological oxidation processing, sodium acetate is added in course of conveying as the carbon source of microorganism；3）Industrial wastewater after microbiological oxidation is handled carries out second of precipitation process, obtains clear water outflow.So as to solve methanol as the inflammable and explosive problem of carbon source, and cost is lower than costs such as methanol, starch, glucose sugar.

Description

A kind of sodium acetate as sewage treatment plant's additional carbon application
Technical field
The present invention relates to sewage treatment area, and in particular to a kind of sodium acetate is used as sewage treatment plant
The application of additional carbon.
Background technology
In the market is in sewage treatment area, and the carbon source being commonly used has methanol, and methanol is used as a kind of inflammable and explosive danger Dangerous product, when using methanol as additional carbon, itself has certain fire risk between its dosing.When methanol tank occurs During fire, it is easily caused storage tank rupture or occurs bumping, liquid spill is occurred continuity fire explosion, it is larger to jeopardize scope, because Certain safe distance is required to surrounding enviroment between this methanol dosing.Simultaneously because it volatilizees, steam is mixed with air easily forms quick-fried Fried property admixture of gas, therefore the electric device in the range of it must use particular design.
The content of the invention
It is an object of the invention to provide a kind of application of sodium acetate as sewage treatment plant's additional carbon, in order to solve The problem of additional carbon is inflammable and explosive.
In order to achieve the above object, the technical scheme is that：A kind of sodium acetate is used as sewage treatment plant's additional carbon Application, comprise the following steps：
1）Trade effluent is adjusted into ph values in regulating reservoir, the trade effluent adjusted after ph values is precipitated in sedimentation basin；
2）Trade effluent after precipitation is delivered to microculture pond and carries out microbiological oxidation processing, is added in course of conveying Sodium acetate is as the carbon source of microorganism, and the addition of sodium acetate is every liter of (N of sewage 5e-Ns)/0.68, NeSewage is current water outlet Nitrogen content mg/l, NsSewage is nitrogen content mg/l in execution standard, and 0.68 is sodium acetate COD equivalent values；
3）Industrial wastewater after microbiological oxidation is handled carries out second of precipitation process, obtains clear water outflow.
The beneficial effects of the invention are as follows：The present invention by using sodium acetate as carbon source carry out microbiological oxidation carbon source so that Methanol is solved as the inflammable and explosive problem of carbon source, and cost is lower than costs such as methanol, starch, glucose sugar.The anti-nitre of microorganism Change speed ratio methanol, starch, glucose sugar fast, easily utilized by microbial digestion.Compared with the carbon sources such as starch, glucose sugar, dissolving It hurry up, and new intermediate product do not produced during microorganism utilizes.
Brief description of the drawings
Fig. 1 be the present invention add schematic flow sheet.
