Abstract

A water treatment device control system and method relate to the technical field of water purification. The system comprises a plurality of sections arranged between a water inlet pipe and a water outlet pipe, and sludge discharge valves are arranged on sludge discharge branch pipes of the sections; a controller is used for controlling the opening and closing of the sludge discharge valves in a sequencing batch mode; a sludge level sensor is arranged in each section; a sludge discharge body measurement unit is arranged on each sludge discharge branch pipe; and the sludge level sensors and the sludge discharge body measurement units are connected to the controller. The method comprises the following steps: when a certain section needs to discharge sludge, the section enters a sludge discharge queue; and when other sections need to discharge sludge, the other sections enter the queue in sequence, and sequencing batch sludge discharge is carried out in a first-in first-out manner. The system and the method have the advantage of avoiding damming and insufficient static pressure.

Description

technical field [0001] The invention relates to a control system and a control method, in particular to a water treatment device control system and method. Background technique [0002] In the technical field of surface water purification and treatment, water treatment devices are mostly used for purification treatment. The water treatment device is a large pool with an inlet pipe at one end and an outlet pipe at the other end. It is a plurality of sections connected in sequence, usually including the following areas or most of them, such as flocculation area, reaction area, rectification area, water distribution area, sedimentation area, water collection area and water outlet area, each section The bottom of each section is equipped with a mud discharge branch pipe, which is used to discharge the purified and deposited sludge in this section and collect it into the sludge discharge main pipe. [0003] In the application of sludge discharge in existing water treatment devic...
