Sewage treatment process is the amount of nutrients important factors affecting biological denitrification environmental equipment, nitrogen in the nitrification process, because nitrobacteria not require organic nutrients in life, a high organic load will affect the growth of nitrifying bacteria, which make nitrification rate decreased, it is generally believed BOD5 value should be less than 20mg / L when the nitration reaction to complete. For denitrification, organic carbon due to its electron donor, so there must be enough carbon in wastewater is generally believed that when the wastewater BOD5 / TKN more than 3 to 5, which considers adequate wastewater carbon environmental protection equipment, do not need external carbon source. And this project is adequate sewage carbon source, no external carbon source.

To protect the submersible pump motor insulation, improved durability, this protection by detecting the pump. Changes in the signal line resistance value, when the humidity reaches 100%, that is when the dew point, the stop signal is detected by the terminal, delay time, the unit is turned on normally open contacts dehumidification heating, dehumidification heating device driver. Until the humidity reached 70% automatically stop heating. If the motor is moving along, the control system to stop working immediately. Integrated wastewater treatment equipment submersible sewage pump shaft and motor shaft concentricity error of size, a direct impact on plant operation noise, vibration and rubber elastic sleeve of life and other environmental equipment engineering, and therefore must be measured and careful adjustment. Coaxial shaft and motor shaft position is reflected by the mutual coupling of the pump and motor coupling.
