一． 设备简介

1、 Equipment introduction

国内半导体行业近几年来的发展令人注目，特别是大型芯片制造企业在东南沿海地区蓬勃发展。芯片制造过程中要消耗大量的水，同时使用大量的化学试剂和特殊气体，排放的废水中成分复杂，因此如何选择废水处理系统，使废水处理达标，并降低其处理费用，同时充分做好中水回用，降低单位产品的能耗，节约水资源，是我们的研究重点。

The development of domestic semiconductor industry in recent years has attracted great attention, especially the large-scale chip manufacturing enterprises in southeast coastal areas. In the process of chip manufacturing, a large amount of water is consumed, and a large number of chemical reagents and special gases are used. The composition of the discharged wastewater is complex. Therefore, how to select wastewater treatment system to make the wastewater treatment meet the standard and reduce its treatment cost, and to fully reuse water, reduce the energy consumption of unit products and save water resources are our research focus.

lehu乐虎水务的中水回用设备工艺已采用膜处理技术，包括预处理、超滤系统和反渗透(RO)系统及EDI系统（可选）几部分。由于废水通过现代技术的深度处理能够达到生产用水标准或者生活杂用水标准，使废水能够循环使用，这样企业对于废水这一块的整体运行费用得到大|大的降低，对环境保护起到很大的作用。

The water reuse equipment technology of macro clean water has adopted membrane treatment technology, including pretreatment, ultrafiltration system, RO system and EDI system (optional). Because the wastewater can meet the production water standard or the standard of domestic miscellaneous water through the advanced treatment of modern technology, the wastewater can be recycled. Therefore, the enterprise can greatly reduce the overall operation cost of the waste water, which plays a great role in environmental protection.
