Welcome to inquire! Contact: Chang Chih-feng. City landfill leachate treatment has been a landfill design, operation and management of a very difficult problem. Leachate is the liquid product in a landfill gravity flow, mainly from precipitation and garbage itself contains water. Because there are many factors that could affect the liquid nature of leather leachate wastewater treatment, including physical factors, chemical factors and biological factors in the flow process, it changes the nature of leachate within a fairly wide range. In general, the pH of the wastewater treatment, COD in the range of 2000 ~ 62000mg / L of, BOD5 from 60 ~ 45000mg / L, the concentration of heavy metals and heavy metal concentrations in municipal sewage consistent between 4-9. Municipal Landfill Leachate is a component of a complex of high concentration organic wastewater wastewater treatment clinics, if left untreated, directly into the environment, it will cause serious environmental pollution. To protect the environment for the purpose of leachate treatment is essential. Precautions centrifugal sewage treatment equipment: Notes sewage treatment equipment centrifugal pump test run: After the unit installation and adjustment is completed, you can test run. Before the test run should do the following: coaxial pump and motor after confirmation, hand rotation coupling, empirically feel the severity of their rotation is uniform, any abnormal sound, check all pumps and motors have a normal phenomenon . (For example, after loosening jammed rotating parts, debris blockage, freezing the pump, packing or mechanical seal too tight or too loose, bent shaft bearings in oil and other issues.) Check the power supply system of sewage treatment equipment, power switch, instrument lines and other related equipment is in good condition. Water valve fully open (when the water valve), while closing the outlet valve and pressure gauge dyeing wastewater treatment method to pump water (such as the use of vacuum valves bottomless water). Loosen the pump cover side bleed plugs, put the best possible residual air in the pump body and then re-tighten. Re-check the centrifugal pump sewage treatment equipment is intact throughout the bolting. Confirm the water conditions are met (such as feed water height, intake pressure, etc.).
