Oily Wastewater Equipment in Mechanical Processing Plants

Product Description

Waste water from machinery processing plant Oily waste water from machinery plant, the floating oil is separated by the grease trap and recovered by the floating oil recovery machine. The machine relies on a lipophilic and hydrophobic ring-shaped oil collecting drag, which is mechanically driven to continuously rotate on the surface of the oil and water at a certain speed to adhere the oil from the oily sewage and squeeze the oil off by the squeezing roller. Into the oil tank, and then sent to the dehydration tank by the oil pump for dehydration, and the slick oil is sold outside. The emulsified oil contained in the wastewater is removed by air flotation after demulsification. Air flotation adopts CAF vortex air flotation. Compared with dissolved air flotation, it has the advantages of simple structure, convenient operation and lower power consumption. With the same processing capacity of 150m3/h, the total power of CAF is 2.94kW, while the total power of dissolved air flotation is above 20kW. The soluble oil and other organic matter remaining in the wastewater are finally treated by biochemical methods. Because the COD concentration of the raw water is not high, the biological contact oxidation process with stable operation and simple operation is selected. The designed residence time is 4h, and the reactor has built-in composite fillers. , Using blast aeration. After solid-liquid separation of the effluent through the inclined tube sedimentation tank, the supernatant is discharged outside the standard. In terms of mechanical industry processing, wastewater is mainly composed of two parts, high chemical oxygen consumption, CODcr, concentrated wastewater and low chemical oxygen consumption dilute wastewater. Among them, the concentrated wastewater is mainly oily wastewater generated by the lubrication, cooling, transmission and other systems in the mechanical processing process and the wastewater generated during the cleaning process before the processing of mechanical parts. It mainly contains lubricating oil, surfactants, cooling and transmission emulsification Oil, etc., dilute wastewater is mainly oily wastewater discharged from the ground and equipment in the mechanical processing workshop. This part of the wastewater has a large amount of water and is the main source of wastewater in the mechanical processing plant.
