Embodiment Construction

[0024] The main idea of ​​the present invention is based on treating the wastewater with a membrane bioreactor and adding suspended sludge before the membrane bioreactor treatment. In this way, the effect of water resource recovery and reuse can be achieved, and the clogging of the membrane bioreactor can be avoided.

[0025] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] According to an embodiment of the present invention, a wastewater treatment method for a chip production line is provided.

[0027] figure 1 is a flowchart of the wastewater treatment method of the chip production line according to the first embodiment of the present invention.

[0028] In step S102, waste water from a chip production line is received, and the waste water contains nano-scale suspended particles. T...

Abstract

The invention discloses a wastewater treatment method for a chip production line. The wastewater treatment method comprises the following steps: receiving wastewater from the chip production line, wherein the wastewater contains nanosized suspended particles; adding suspended matter sludge into the wastewater to adsorb the nanosized suspended particles in the wastewater so as to form over-microsized suspended particles; performing membrane bioreactor treatment on the wastewater to remove the suspended particles in the wastewater. With the adoption of the wastewater treatment method, a problem of very quick blockage of filter materials often caused by an excessively simple treatment mode in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a wastewater treatment method for a chip production line. Background technique [0002] In semiconductor manufacturing technology, semiconductor chips with various functions are formed through a series of processes such as photolithography, etching, deposition, ion implantation, grinding, cleaning, etc., and then the semiconductor chips are packaged and electrically tested, and finally form the end product. At present, in the manufacturing process of semiconductor chips, a large amount of industrial waste water is generated. [0003] In the existing wastewater treatment process, the sequential batch activated sludge method (SBR) or biological contact oxidation method or biological aerated filter (BAF) is usually used alone, which can only perform a single treatment on wastewater, such as filtering Or microbial reaction or detoxification, etc., because the treatment...
