Abstract

The invention discloses processing equipment for cutting fluid waste water. The equipment is characterized by comprising a sewage pump, a multi-phase medium pump, a medicine addition system, a coagulation air floatation separator and an integrated purifier. The medicine addition system comprises a de-emulsifier addition box and a PAM coagulant aid addition box; the integrated purifier comprises a multi-stage biomembrane purifying zone, a biological active carbon purifying zone and a contact deposition filtering adsorption separating zone. The invention also provides a processing method of the above processing equipment; and reasonable connection of each apparatus realizes processing on the cutting fluid waste water. Through the integrated design, the invention can realize advantages of small land occupation of equipment, high degree of automation, good purification effect and convenience for daily maintenance and management, etc.

Description

technical field [0001] The invention relates to the field of industrial waste water purification, in particular to a treatment device and method for cutting fluid waste water generated during mechanical processing such as turning, grinding, cutting and rolling. Background technique [0002] Cutting fluid plays a role in cooling, lubricating, cleaning and rust prevention in machining, steel manufacturing, bearing processing and other processes. Cutting fluid is one of the metal processing lubricants used in large quantities in the locomotive and automobile manufacturing industries. It has good lubricity, cooling and cleaning properties, and is widely used in various cutting processes. However, its biggest disadvantage is that it is easily corrupted and deteriorated during use, the stability of the working fluid is poor, and the service life is short. Especially in the hot summer in the south, the use cycle is only one week, and some even rot and stink in only two or three da...
