Preprocessing method for measuring desaturase liveness of drinking water biological active carbon treatment process

Abstract

The invention provides a dehydrogenase activity detection pretreatment method used in drinking water biological active carbon treatment technique, which is a mixed solution composed of three kinds of reagents, under the control of adding proportionment, adding time and operational condition, the pretreatment is finished, thereafter the measuring process is selected and the specification curve is drawn. The invention has the advantages that, from the chemical angle, using organic reagent to extract and elute the adsorbed microorganism, the desorption degree is high; testing the active carbon carried dehydrogenase activity with effective proportioning and oscillation mode, and confirming the optimum organic solvent combination and proportioning for achieving the maximum measuring effect; providing the reference for similar biological carrier activity test, which is suitable for biological activity test of biological carrier in drinking water treatment technique.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a pretreatment method for measuring dehydrogenase activity of activated carbon fillers in the drinking water activated carbon treatment process. technical background [0002] Due to the limitations of conventional drinking water treatment processes, the application of advanced treatment processes is becoming more and more common. Among them, biological activated carbon technology has been widely used because it has both adsorption and biological treatment functions, and evaluating the biological activity of biological carrier fillers is to determine its biological treatment. The key to the strength of the effect. The dehydrogenase activity of organisms reflects the activity state of organisms to a large extent, so dehydrogenase activity detection is widely used in the field of water treatment. Since the dehydrogenase activity assay method was formally used in biochemical...

Problems solved by technology

In the drinking water ozone biological activated carbon process, the adsorption carrier of bacteria and other microorganisms is granular activated carbon with complex microporous structure, and its adsorption mechanism is different from that of activated sludge. Membrane-hanging is a treatment process of carbon bed biological formation, and its adsorption effect on the carrier may be stronger than that of drinking water. Therefore, in the ozone bio-activated carbon process, ultrasonic elution or shaking and crushing methods cannot completely remove the adsorbed microorganisms, thereby Causes subsequent measured values ​​to be small or negative

The experimental results show that the pretreatment method in the above dehydrogenase activity is difficult to efficiently measure the activity of activated carbon fillers
