一． 設(shè)備簡(jiǎn)介

1、 Equipment introduction

國(guó)內(nèi)半導(dǎo)體行業(yè)近幾年來(lái)的發(fā)展令人注目，特別是大型芯片制造企業(yè)在東南沿海地區(qū)蓬勃發(fā)展。芯片制造過(guò)程中要消耗大量的水，同時(shí)使用大量的化學(xué)試劑和特殊氣體，排放的廢水中成分復(fù)雜，因此如何選擇廢水處理系統(tǒng)，使廢水處理達(dá)標(biāo)，并降低其處理費(fèi)用，同時(shí)充分做好中水回用，降低單位產(chǎn)品的能耗，節(jié)約水資源，是我們的研究重點(diǎn)。

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.

宏潔水務(wù)的中水回用設(shè)備工藝已采用膜處理技術(shù)，包括預(yù)處理、超濾系統(tǒng)和反滲透(RO)系統(tǒng)及EDI系統(tǒng)（可選）幾部分。由于廢水通過(guò)現(xiàn)代技術(shù)的深度處理能夠達(dá)到生產(chǎn)用水標(biāo)準(zhǔn)或者生活雜用水標(biāo)準(zhǔn)，使廢水能夠循環(huán)使用，這樣企業(yè)對(duì)于廢水這一塊的整體運(yùn)行費(fèi)用得到大|大的降低，對(duì)環(huán)境保護(hù)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.
