Example Embodiment

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] Reference Figure 1-6 , An environmentally friendly treatment equipment for chip silicon production, including pickling tank 1. Silicon must be separated from silicon compounds during the silicon manufacturing process. After separation, in order to better improve the quality of silicon, the silicon needs to be acidified Washing, thereby improving the quality of silicon, which in turn helps to improve the quality of the chip. The lower end of the pickling tank 1 is provided with a drain pipe 2. After the pickling is completed, the waste liquid in the pickling tank 1 can pass through the drain The pipe 2 is discharged from the pickling ta

Abstract

The invention discloses environment-friendly treatment equipment for chip silicon production, and further provides an operating method of the environment-friendly processing equipment for chip siliconproduction. The environment-friendly treatment equipment comprises an acid washing tank, wherein a liquid discharge pipe penetrates through one side of the lower end of the acid washing tank; one endof the liquid discharge pipe is connected with a first electric control three-way valve; two sides of the first electric control three-way valve are respectively connected with sewage discharge pipes; two reaction tanks penetrate through one ends of the two sewage discharge pipes; mixing devices are arranged on the two reaction tanks; two medicine conveying pipes penetrate through one sides of the upper ends of the two reaction tanks; a second electric control three-way valve is commonly connected between the two medicine conveying pipes; and one end of the second electric control three-way valve is connected with a medicine storage tank. According to the environment-friendly treatment equipment for chip silicon production and the operating method thereof, the reaction time between wasteliquid and medicament can be ensured, and the waste liquid and the medicament can be well fully reacted, so that the treatment quality and efficiency of the waste liquid are improved, impurities in the waste liquid are filtered and precipitated, and therefore, the environment is better protected.
