A water treatment system comprises a reaction tank, a sedimentation tank, a filter tank and a clean water tank which are sequentially communicated with one another, and further comprises a first turbidity meter, a first flow meter, a chemical tank, a metering pump, an automatic control system and a monitoring system, wherein the first turbidity meter and the first flow meter are arranged at a raw water inlet; a chemical adding point is arranged in front of the water inlet of the reaction tank; the metering pump is communicated with the chemical tank and the chemical adding point respectively; a simulating inclined tube device is arranged at the water outlet of the reaction tank; an inclined tube water inlet and an inclined tube water outlet are formed in the simulating inclined tube device; the inclined tube water inlet is communicated with the water outlet of the reaction tank; a second turbidity meter is arranged at the inclined tube water outlet; the first turbidity meter, the first flow meter, the metering pump, the second turbidity meter and the monitoring system are connected with the automatic control system. The water treatment system can greatly improve the chemical adding accuracy and solve the problem of feedback time lag, so that the water quality is ensured and the treatment efficiency of the water treatment system is improved.
Description
technical field [0001] The invention relates to the technical field of water treatment, in particular to a water treatment system. Background technique [0002] With the improvement of people's living standards in our country and the enhancement of environmental protection awareness, the country's requirements for water purification production and sewage treatment are also constantly increasing, and the treatment indicators are also becoming more and more stringent, and the addition of flocculants is a must in the water treatment system. indispensable link. At present, the traditional water purification production system and sewage treatment system adopt the following dosing methods: manual control, empirical data dosing, dosing according to raw water flow control, open-loop control dosing according to water quality and raw water flow, etc. [0003] None of the above-mentioned control methods take into account the influence of hydraulic conditions and various parameter chan...
