Abstract

The invention discloses a kind of methods of processing yuba wastewater, river mud sample are acquired, using screening and culturing medium separate microorganism.After culture, rod-shaped microorganism is selected.37 DEG C of culture 5d, are inoculated into 6 10% inoculum concentration in yuba wastewater.Anode of fuel cell is added in yuba wastewater after inoculation, and room temperature culture is handled.By the processing of this method, yuba wastewater COD (COD) 16496mg/L after cultivating 20d, measures the minimum 668mg/L of COD.COD removal rates reach 95.96%, can be directly discharged in environment.The present invention provides a kind of methods of processing yuba wastewater.

Description

A method of handling yuba wastewater using microorganism battery
Technical field
The present invention relates to a kind of food processing fields, and in particular to a method of processing yuba wastewater processing.
Background technology
It produces and mainly contains starch, protein and fat etc. in the waste water of bean curd stick, the very high concentrations of content of organics use Physical chemistry solves for the mode of main method, such as：Dosing is flocculated, and is then precipitated, or carries out air supporting, still The disadvantage of this method is that treatment effeciency is low, and operating cost is high.The waste water labile organic compound content of bean curd stick is high, it is less containing The harmful substance of poison, is handled using the method for microorganism, and not only treatment effeciency is high, while also portion of energy is in form of electricity Output.
Invention content
The object of the present invention is to provide a kind of methods of processing yuba wastewater.
The invention is realized by the following technical scheme：
A kind of processing yuba wastewater needs following reagent and consumptive material：
Screening and culturing medium
Glucose, peptone, beef extract, yeast powder, KCl, NaH2PO4·2H2O, Na2HPO4·12H2O。
Nfion117 proton semi-permeable membranes
Biological fuel cell structure
Battery is made of two rectangular glass containers, centre flanged joint, each long 8cm of container, wide 8cm, high 8cm.Intermediary interface presss from both sides proton semi-permeable membrane, uses seal with elastometic washer.One chamber is anode, and a chamber is cathode.Add in anode Enter and configure yuba wastewater, deionized water is added in cathode.When battery works, constantly it is passed through into cathode chamber with air compressor Air.
Processing method：
1, acquisition river mud sample is packed into the collection tube of sterilizing, is cultivated in anaerobic culture box using screening and culturing medium.
2, Anaerobic culturel is after 1 week, separate microorganism.After microscopy, rod-shaped microorganism is selected.
3, rod-shaped microorganism, 37 DEG C of culture 5d, with the inoculum concentration of 6-10% are separated to using screening and culturing medium Anaerobic culturel It is inoculated into yuba wastewater.
4, anode of fuel cell is added in the yuba wastewater after being inoculated with, and is handled.
Specific implementation mode：
Technical scheme of the present invention is described further below by specific embodiment：
Embodiment 1
A kind of processing yuba wastewater needs following reagent and consumptive material：

Nfion117 proton semi-permeable membranes
Biological fuel cell structure
Battery is made of two rectangular glass containers, centre flanged joint, each long 8cm of container, wide 8cm, high 8cm.Intermediary interface presss from both sides proton semi-permeable membrane, uses seal with elastometic washer.One chamber is anode, and a chamber is cathode.Add in anode Enter and configure yuba wastewater, deionized water is added in cathode.When battery works, constantly it is passed through into cathode chamber with air compressor Air.
Processing method：
1, acquisition river mud sample is packed into the collection tube of sterilizing, is cultivated in anaerobic culture box using screening and culturing medium.
2, Anaerobic culturel is after 1 week, separate microorganism.After microscopy, rod-shaped microorganism is selected.
3, rod-shaped microorganism, 37 DEG C of culture 5d, with the inoculum concentration of 6-10% are separated to using screening and culturing medium Anaerobic culturel It is inoculated into yuba wastewater.
4, anode of fuel cell is added in the yuba wastewater after being inoculated with, and is handled, and during handling waste water, open-circuit voltage reaches To 1.1V, internal resistance is 730 Ω.
By the processing of this method, yuba wastewater COD (COD) 16496mg/L after cultivating 20d, measures COD most Low is 668mg/L.COD removal rates reach 95.96%, can be directly discharged in environment.
