Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] A kind of activated sludge metabolic state light deflection detection method of the present invention, specifically implement according to the following steps:

[0027] Step 1, fully contacting the polyvinyl alcohol pellets with the activated sludge, and taking out the polyvinyl alcohol pellets after enriching the microorganisms to obtain the activated sludge test sample;

[0028] Step 1 is specifically implemented as follows: Add polyvinyl alcohol pellets into a container with pores, place the container inside the aeration tank of the biological treatment system, and fix the aeration equipment at the bottom of the container so that the pellets are in a suspended state, and the active The sludge is fully contacted so that the activated sludge microorganisms are enriched on the pellets, and then the polyvinyl alcohol pellets are taken o...

Abstract

The invention discloses an activated sludge metabolic state light deflection detection method, and the method is specifically implemented according to the following steps: 1, fully contacting polyvinyl alcohol spheres with activated sludge, enriching microorganisms and then taking out the polyvinyl alcohol spheres to obtain an activated sludge detection sample; 2, pretreating the sample obtained in the step 1; 3, carrying out light deflection distance measurement on the pretreated sample obtained in the step 2; 4, analyzing the light deflection distance measurement obtained in the step 3, andindicating that the larger the light deflection distance is, the better the microbial metabolic activity is, thereby completing the metabolic state detection of the activated sludge, and solving the problem of long time consumption of sludge detection indexes in the prior art.

Description

technical field [0001] The invention belongs to the technical field of wastewater biological treatment, and relates to a method for detecting light deflection of activated sludge metabolic state. Background technique [0002] Activated sludge biological treatment is the most commonly used sewage treatment method. It mainly removes dissolved and colloidal organic matter in sewage by means of adsorption and biological oxidation decomposition. The sewage treatment effect mainly depends on the activity of sludge. Therefore, in the sewage system During operation, the sludge activity needs to be detected. At present, SV is commonly used in the detection of sludge properties. 30 (Sludge Settling Ratio), SVI (Sludge Volume Index), MLSS (Mixed Liquor Suspended Solids Concentration), MLVSS (Mixed Liquor Volatile Suspended Solids Concentration), microscope detection and other methods; microbial indicators can also be used for sludge activity detection The commonly used methods are ad...
