Description

technical field [0001] The invention belongs to the field of equipment related to environmental protection treatment, and in particular relates to an intelligent PAM dosing device. Background technique [0002] In the traditional sludge treatment process, because PAM (polyacrylamide) is difficult to dissolve, it is difficult to master the essentials of manual dissolution operation, and it is easy to form flocculation during the dissolution process, and the formation of flocculation in the liquid medicine will affect the normal operation of the dosing system. run. At the same time, the medicament after the formation of flocs cannot be dissolved normally, thereby wasting the medicament and increasing the cost of water treatment. In order to solve the above problems and save labor costs, under normal circumstances, a fully automatic dosing device is used for dosing PAM (polyacrylamide). [0003] PAM automatic dosing device, including PAM automatic dissolving device (dissolvin...
