Description

A integrative device is thrown to medicament essence for sewage treatment Technical Field The invention relates to the technical field of sewage treatment, in particular to a reagent accurate throwing integrated device for sewage treatment. Background In industrial and urban sewage treatment processes, chemical agent addition is a critical ring, and various chemicals such as coagulant, flocculant, coagulant aid, pH regulator and the like are often involved. In order to achieve optimal treatment (e.g., optimal flocculation settling efficiency, minimum effluent turbidity, and most stable pH), it is often necessary to simultaneously add two or more pharmacological solutions to the wastewater in a predetermined, strict volumetric or mass ratio. The synergy of such multiple agents requires that the dosing system must have high precision proportional control capability, the core of which is to accurately meter and deliver the flow of each agent in real time. At present, common implementation modes mostly depend on a plurality of independent metering pumps, peristaltic pumps or rough control is carried out by adjusting the opening degree and time of a valve, and a control system of the control system is often relatively independent or simply linked. However, prior art solutions have significant drawbacks in achieving accurate proportional control. Firstly, the dosing accuracy of the system is limited by a plurality of factors, such as long-term running accuracy drift of a single metering pump, nonlinearity of flow characteristics of different medicaments caused by viscosity difference, and obvious influence of pipeline pressure fluctuation on low-flow medicament dosing. Secondly, the existing equipment is lack of an effective online real-time calibration and compensation mechanism, and the proportion deviation generated by the factors cannot be dynamically corrected. The misalignment of the proportion control can directly lead to serious consequences that the medicaments deviating from the optimal proportion can not form expected synergistic effect in sewage from the technical aspect, and can cause the problems of bad generation of flocs, reduced sedimentation efficiency, out-of-standard water quality and the like, thereby directly influencing the stability and reliability of the treatment effect. From the economic aspect, in order to compensate for poor effect, a certain medicament is often prone to be excessively added, which not only causes expensive chemical medicament waste and obviously increases the ton water operation cost in the sewage treatment process, but also possibly introduces new secondary pollution risks due to medicament residues, and finally seriously influences the practical value and the economical efficiency of the whole medicament adding system. Therefore, developing a precise-throwing integrated device capable of realizing high-precision, self-adaptive and multi-medicament proportion synchronous control becomes a key requirement for improving sewage treatment efficiency and reducing operation cost. Disclosure of Invention (One) solving the technical problems Aiming at the problems in the prior art, the invention provides a reagent accurate-throwing integrated device for sewage treatment, which aims to solve the technical problems in the background art.
