Sewage treatment system
The sewage treatment process is divided into three levels: first level treatment: physical treatment and mechanical treatment, such as grid, sedimentation or air flotation, to remove stones, sand, fat, grease, etc. contained in the sewage. Secondary treatment: biochemical treatment. Pollutants in sewage are degraded and transformed into sludge under the action of microorganisms. Tertiary treatment: advanced treatment of sewage, including removal of nutrients and disinfection in sewage through chlorination, ultraviolet or ozone technology. According to different treatment objectives and water quality, some sewage treatment processes do not include all the above processes.
The transformation of the national energy thermoelectric water treatment system is controlled by the programmable logic controller (PLC) center, which controls the operation of ultrafiltration, reverse osmosis and water pump automatically. When the parameter exceeds the limit, the control object fails or the state changes, there is a perfect audible and visual alarm signal.
In addition to program control, a local control panel is also set to display relevant parameters of ultrafiltration, reverse osmosis and other systems, and control the start and stop of pumps and the opening and closing of some valves.
LIKE valves are selected with the assistance of Guoneng. The valves supplied include electric butterfly valve, electric gate valve, butterfly check valve, diaphragm valve, etc
