Forced reaction coagulation clarification system capable of realizing intelligent regulation and control

Abstract

The invention discloses a forced reaction coagulation clarification system capable of realizing intelligent regulation and control. The system comprises a clarification tank, a forced coagulation regulation and control unit and an analysis unit and is particularly applicable to the operation condition of frequently fluctuant water inflow. According to the system operation condition monitored and collected in real time by each functional module, the analysis unit accurately calculates the sludge generation amount of the clarification tank and the flocculation reaction degree of mixed liquid ina reaction area, analyzes the real-time operation state of the clarification tank and takes corresponding regulation and control measures. Through the forced coagulation regulation and control unit, the flocculation crystal nucleus quantity and sludge discharge amount of a forced coagulation reaction are accurately regulated and controlled, an optimized forced coagulation reaction environment is constructed, the growth and adsorption precipitation of flocculation crystal nuclei are effectively controlled, and it is ensured that the physical and chemical properties of floc in the reaction areastay in a good stable state. The system realizes automatic control over the intelligent and precise forced coagulation reaction environment, automatic control over the discharge of residual sludge, automatic control over a flushing device and the like and ensures the stable operation of the clarification tank, the effluent quality of the system is improved, and the operation benefits of the systemare increased.

Problems solved by technology

Traditional coagulation and clarification systems often use mechanically accelerated clarification tanks as their core treatment facilities. It is a suspended sludge clarification system that has high requirements for the stability of influent water and water quality. According to the follow-up process equipment demand fluctuates greatly, the water inflow is extremely unstable, resulting in the ineffective formation of floc particles, the state of the mixed liquid in the reaction zone and the physical and chemical properties of the flocs change greatly, resulting in violent disturbance of the sludge layer, and some flocs The particles will rise with the water flow, causing the quality of the effluent to deteriorate, and even serious "pool overturning" phenomenon

When the system is running, the adjustment of equipment operating parameters is often based on manual experience, which is highly random, and cannot accurately and timely regulate the reaction conditions of flocculation and clarification. The concentration of flocs in the reaction zone and the sedimentation performance cannot be well guaranteed. The degree of automation of the system is low, and the labor intensity is high. The water output effect is very unstable

[0003] In view of the above reasons, in order to solve the problems that the traditional coagulation and clarification system cannot adapt to the operating conditions of fluctuating water inflow, poor impact load resistance, floc formation concentration and settling performance in the clarifier reaction zone cannot be well guaranteed, it is urgent to develop and design a system. A set of clarification system suitable for fluctuating water inflow, enhanced coagulation effect, high degree of automation and precise control
