Embodiment Construction

[0024] A treatment process for bearing production wastewater, comprising the following steps:

[0025] (1) The wastewater from bearing production first passes through the artificial grid 1 to remove larger floating objects and impurities in the sewage, and then enters the oil separation adjustment tank 2 to separate and stir the floating oil in the wastewater evenly (the oil separation adjustment tank includes There is a grease trap at the front end and a regulating pond at the rear. The grease trap separates the floating oil in the sewage, and an underwater agitator is installed in the regulating pond to make the water quality and quantity equal), and then it is lifted to the vortex by the suction pump In the concave air flotation system 3, polyaluminum chloride and polyacrylamide are used to remove suspended solids and petroleum in wastewater;

[0026] (2) The waste water treated by the vortex-concave air flotation system 3 enters the iron-carbon micro-electrolysis reactor 4...

Abstract

The invention discloses a treatment process for bearing production wastewater. The treatment process comprises the following steps: firstly, enabling bearing production wastewater to enter an oil-separation adjusting tank; separating floating oil in the wastewater and agitating uniformly; then lifting the wastewater into a cavitation air floatation system to remove suspension matters and petroleum in the wastewater; conveying the wastewater treated by the cavitation air floatation system into an iron-carbon micro-electrolysis reactor and carrying out a Fenton reagent and iron-carbon micro-electrolysis combined oxidation reaction to reduce chemical oxygen demand and improve the ratio value of biochemical oxygen demand / chemical oxygen demand of the wastewater; conveying the wastewater reacted in the iron-carbon micro-electrolysis reactor into a coagulation precipitation tank, adjusting the pH (Potential of Hydrogen) and carrying out a coagulation and flocculation reaction; enabling reacted liquid supernatant to flow into a middle water pond to sequentially enter a UASB (Up-flow Anaerobic Sludge Bed / Blanket) anaerobic reaction tank, a CASS (Cyclic Activated Sludge System) reaction tank and a water discharging tank and filtering by a multi-medium filter; discharging after the water reaches standards. The treatment process is simple in management and good in wastewater treatment effect; a sludge expansion problem which usually and easily occurs in a traditional active sludge method is overcome; the water can be discharged after the water quality reaches the standards and the treatment process is good for protecting the ecological environment.

Description

[0001] technical field [0002] The invention relates to the treatment of wastewater in the field of machinery manufacturing, in particular to a treatment process for bearing production wastewater. Background technique [0003] Bearing enterprises mainly produce inner and outer rings of bearings and finished bearings. The basic drainage system is a combined system, where production wastewater, domestic sewage, and rainwater are discharged together, of which domestic sewage occupies a certain proportion. The production wastewater mainly comes from the ground cleaning water of each workshop, equipment leakage and leakage water and emulsion wastewater. If the waste water is discharged directly without treatment, it is bound to cause serious pollution to the environment. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a treatment process for bearing production wastewater. After the bearing production wastewater...
