On December 21st, the reporter learned from the Safety Technology Division of Dongfeng Commercial Vehicle Body Factory that the COD (chemical oxygen demand) emissions of the body factory in 2009 was reduced by 20% on the basis of 2005, and successfully completed the release of Dongfeng Commercial Vehicle Company. Emission reduction targets.
It is understood that Dongfeng commercial vehicle body factory mainly through three measures to achieve emission reduction targets: First, strengthen wastewater discharge management, control of wastewater discharge, reduce the concentration of wastewater discharge. We will concentrate the discharge of waste water for approval and discharge it in strict accordance with the technological regulations. The second is to improve the operation procedures of wastewater treatment processes, enhance the awareness of staff in reducing emissions, and guide the wastewater treatment operators to timely adjust the dosage of the pharmaceuticals according to the changes in water quality. The COD concentration is controlled below 350 mg/L. The third is to reduce wastewater discharge through technological progress.
YB rotary vane pump main features
YB
rotary vane pump is with by-pass valve built-in. The rotary vane pump
uses a rotor with sliding vanes to drive the liquid transfer. The
material of construction is nodular cast iron with self-lubricating
vanes. Due to its superior performance, the vane pump can handle viscous
and volatile liquid and require less horsepower than other equivalent
pumps. The self-priming vane pump has its obvious advantage in the
transmission of high flow at low revolution.
