AUTOMATIC CONTROLLING SYSTEM FOR SEWAGE WASTE WATER AND SEWAGE WATER TREATMENT SYSTEM

摘要

An automatic control system for a sewage and wastewater-treating apparatus is provided to control various devices of the sewage and wastewater-treating apparatus automatically through a program, thereby securing reliability, convenience, and accuracy in operation of the sewage and wastewater-treating apparatus. A sewage and wastewater-treating apparatus comprises a flow rate-regulating bath, a contact oxidation bath for treating pollution materials by using microorganisms attached on a contact member, and a membrane separation bath for separating the treated water by using a membrane. A first motor transports the raw water from the flow rate-regulating bath to the contact oxidation bath. A second motor supplies air to respective baths. A third motor drives the membrane separation bath to separate the treated water. A PLC(Programmable Logic Controller) board(3) is installed at the sewage and wastewater-treating apparatus to control target devices. A program for controlling the system is stored in the PLC board. A body wraps the PLC board to protect the PLC board.
