Method for treating high concentrated organic wastewater by membrane yeast reactor (MYR)

Abstract

The invention discloses a new method for treating high-concentration organic wastewater by a membrane yeast reactor (MYR). The method comprises that: on the basis of fully utilizing advantages of membrane separation technology, naturalized specific microzyme is screened aiming at different water quality to replace activated sludge in a routine membrane reactor method; through the membrane separation process, the method realizes effective interception of the specific microzyme in the reactor, achieves good solid-liquid separation effect, and greatly improves the degradation effect of strain on the high-concentration organic wastewater simultaneously. The method has the advantages of simplicity, feasibility, few equipment, low investment, no secondary pollution and stable effect on organism degradation.

Description

technical field

[0001] The invention relates to a "membrane yeast reactor (MYR)" method for treating high-concentration organic wastewater, which belongs to the technical field of wastewater treatment. Background technique

[0002] High-concentration organic wastewater is widely distributed in fermentation, breeding, food, chemical industry and other fields. Its main feature is that the COD concentration is high, generally above 10,000 mg / L, and some even as high as hundreds of thousands or hundreds of thousands (mg / L). Some of the wastewater also contains high concentrations of sulfur, ammonia, salt and toxic of organic matter. If the waste water is directly discharged into the river without treatment, it will lead to water pollution, and at the same time affect the stable operation and compliance rate of subsequent sewage treatment plants, causing serious problems to environmental protection, and its destructiveness is far more than that of municipal sewage and other low-...

Examples

Embodiment example

[0027] 1. A pharmaceutical factory is a high-tech enterprise that produces colistin sulfate. The content of organic matter (COD) in its production wastewater is relatively high, with an average of 20,000 mg / L. At the same time, the wastewater also contains a large amount of antibiotics and refractory organic matter, which are refractory One of the wastewater treatment.

[0028] 2. Install the membrane yeast reactor test device, and use the automatic control system to organically combine the regulating tank, yeast tank and water storage tank to realize the wastewater treatment function.

[0029] 3. Using yeast enrichment and separation technology to separate and obtain specific yeast that efficiently degrades organic matter in colistin sulfate wastewater:

[0030] Take 3 grams of mud sample from the soil around the colistin sulfate wastewater outlet, insert it into 300mL PDA medium, enrich and cultivate it for 2 days, take it out and centrifuge at 8000rpm for 15min to obtain ac...
