Abstract
The invention discloses a method for detecting quality of a cationic polyacrylamidesludge treatment agent. The method comprises the following steps: 1, preparing a solution; 2 detecting the dissolution time; 3 detecting the conductivity; 4, detecting the solution viscosity; 5 detecting the quality cation degree; 6, detecting the content of an organic matter; 7, determining whether the detected product is qualified according to the acceptable quality level of the cationic polyacrylamide. The method is applicable to mass detection of a preparation, cationic polyacrylamide, for carrying out sludge treatment in a sewage treatment technology, so as to ensure the quality of using the preparation and the sludgetreatment effect. By adopting the method disclosed by the invention, the quality of the cationic polyacrylamide sewage treatment agent used for sewage treatment is effectively ensured. Thus, the sewage treatment effect is ensured, the sewage treatment efficiency is improved, the operation cost is saved, and risks in production and operation as well as device safety for sewage treatment are reduced.
Description
technical field [0001] The invention belongs to a sewage treatment technology, in particular to a quality detection method of cationic polyacrylamide used for sludge treatment in the sewage treatment process. To ensure the quality of the preparation and the effect of sludge treatment. Background technique [0002] Cationic polyacrylamide is a preparation used for sludge dehydration in sewage treatment. It has the advantages of fast dehydration, decontamination and decolorization. It is a good dehydrating agent and flocculant. It is widely used in urban sewage and Industrial wastewater treatment process. The effect of sludge treatment is directly related to the quality of the preparation. Due to the large amount of use and many batches, the quality and performance indicators of cationic polyacrylamide sludge treatment agents produced by different manufacturers and batches are different. In the process of use, it is necessary to target different performance indicators of dif...
