The precise metering needs to be matched with the uniform mixing, the viscous fluid industry (such as sludge) is relatively extensive from the current market perspective, the main strategy adopted for the dosage and the uniformity of the mixing is excessive adding for convenient use, but from the trend perspective, if the precise metering and uniform mixing technology is adopted, the adding and mixing can be carried out along with the operation, the effect is ensured, and meanwhile, the resource waste is prevented; therefore, a novel continuous mixing and conveying system is adopted to optimize the treatment process, and the treatment efficiency is inevitably improved.
