Description

A water purifier dosing device based on coagulation reaction sedimentation tank

technical field

The utility model belongs to the technical field of chemical water treatment and relates to a water purifying agent dosing device based on a coagulation reaction sedimentation tank.

Background technique

In the pretreatment process of chemical raw water in power plants, the water purifying agent used for mixed flocculation of raw water needs to be prepared according to a certain concentration in the dosing device, and then transported to the coagulation reaction sedimentation tank. In the past production process of water production, the concentration of the prepared water purifier was uncertain, mainly because the purchased water purifier generally had a high concentration, and it was necessary to add a certain proportion of water to prepare a coagulation water purifier that met the standard before it could be used. However, in the process of actually preparing the water purifying agent, since the ratio of the agent and the amount of water, and the amount of water added are all controlled by humans, human errors lead to uncertainty in the concentration of the water purifying agent prepared each time. Moreover, it takes a certain amount of time for the flocculation reaction and precipitation of the water purifying agent and raw water, which brings difficulties to the control of the dosage and makes the operation more difficult. If the amount of chemical is not enough, the effluent index cannot be reached, and it can only be discharged, resulting in a waste of raw water; if the amount of chemical is added too much, the effluent index cannot be reached, resulting in a waste of water purifier. If there is a problem with the concentration of the water purifying agent after preparation, it will increase the difficulty of operation for the operator, and it is necessary to continuously adjust the opening of the valve to control the amount of dosing and the amount of raw water inflow to meet the qualified indicators. In addition, this adjustment process will cause waste of water purifiers and raw water, which is not conducive to economic benefits.
