Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] Embodiments of the present invention provide a treatment system and treatment process for cutting waste liquid, such as figure 1 As shown, the treatment system includes a first adjustment tank 1, a pretreatment device 2 and an MBR treatment device 3, and the chip waste liquid is sequentially treated by the first adjustment tank 1, the pretreatment device 2 and the MBR treatment device 3 to meet the discharge requirements. The specific requirements are as follows:

[0026] (1) Mix the cutting waste liquid after removing impurities evenly, and adjust the pH to 5-8;

[0027] First, the cutting waste liquid is collecte...

Abstract

The invention discloses a cutting waste liquid treatment system and a cutting waste liquid treatment process.The cutting waste liquid treatment system comprises a first regulating tank, a pretreatment device and an MBR treatment device.The cutting waste liquid treatment process includes steps: regulating pH of cutting waste liquid in the first regulating tank to 5-8; performing photocatalytic oxidation, and separating generated suspended matters, wherein photocatalytic oxidation includes a first oxidation stage and a second oxidation stage, the first oxidation stage adopts a medium-pressure mercury lamp or an iodine-tungsten lamp as a light source, and the second oxidation stage adopts an ultraviolet lamp as a light source; sequentially performing preheating treatment, anaerobic fermentation treatment and MBR filter treatment.By two-stage photocatalytic oxidation treatment, primary degradation and secondary degradation of annular and chainlike organic matters in the waste liquid are realized, biodegradability of the waste liquid is improved, subsequent anaerobic fermentation treatment and MBR filter treatment are benefited, and recycling of the waste liquid and standard emission of pollutants are realized.The cutting waste liquid treatment process is simple, convenient, low in investment cost and operation cost and beneficial to popularization.

Description

technical field [0001] The invention relates to cutting waste liquid treatment technology, in particular to a cutting waste liquid treatment system and treatment process. Background technique [0002] Cutting fluid is a commonly used coolant and lubricant in metal processing and mechanical processing. The cutting process plays the roles of lubrication, cooling, cleaning and rust prevention. [0003] During the use of cutting fluid, a large amount of cutting waste fluid is produced due to the failure of impurities mixed in. The waste liquid is composed of petroleum, surfactants, preservatives, etc. Some of the additives are carcinogenic. If they are discharged without treatment, they will seriously pollute the environment and endanger human health. They must be treated before they are discharged. [0004] Most enterprises in the manufacturing industry at home and abroad mainly adopt contract entrustment or self-disposal for the disposal of cutting waste fluid. Sewage disch...
