一．    設備簡介

One Equipment introduction

國內(nèi)半導體行業(yè)近幾年來的發(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。芯片制造過程中要消耗大量的水，同時使用大量的化學試劑和特殊氣體，排放的廢水中成分復雜，因此如何選擇廢水處理系統(tǒng)，使廢水處理達標，并降低其處理費用，同時充分做好中水回用，降低單位產(chǎn)品的能耗，節(jié)約水資源，是我們的研究重點。

In recent years, the development of domestic semiconductor industry is remarkable, especially the large-scale chip manufacturing enterprises are booming in the 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 at the same time. The composition of the discharged wastewater is complex. Therefore, how to select the wastewater treatment system, make the wastewater treatment meet the standard, and reduce the treatment cost, and at the same time, make full use of the reclaimed water, reduce the energy consumption per unit product, and save water resources is our research focus.

宏潔水務的中水回用設備工藝已采用膜處理技術，包括預處理、超濾系統(tǒng)和反滲透(RO)系統(tǒng)及EDI系統(tǒng)（可選）幾部分。由于廢水通過現(xiàn)代技術的深度處理能夠達到生產(chǎn)用水標準或者生活雜用水標準，使廢水能夠循環(huán)使用，這樣企業(yè)對于廢水這一塊的整體運行費用得到大|大的降低，對環(huán)境保護起到很大的作用。

Membrane treatment technology has been adopted in the process of reclaimed water reuse equipment of Hongjie water, including pretreatment, ultrafiltration system, reverse osmosis (RO) system and EDI system (optional). Due to the advanced treatment of wastewater by modern technology, it can meet the production water standard or domestic miscellaneous water standard, so that the wastewater can be recycled, so that the overall operation cost of the enterprise for wastewater has been greatly reduced, which plays a great role in environmental protection.

3. 集成控制系統(tǒng)和集成儀表系統(tǒng)等，方便操作管理；

3. Integrated control system and instrument system to facilitate operation and management;

4. 設備具有耗材更換自動提示功能，并且耗材的更換周期取決于水質和壓力的變化，而非根據(jù)耗材的使用時間，考慮到了各地水質的差異，設計更；

4. The equipment has the function of automatic prompt for the replacement of consumables, and the replacement cycle of consumables depends on the change of water quality and pressure, not on the use time of consumables. Considering the difference of water quality in different places, the design is more reasonable;

5. 能有效地進行固液分離，將廢水中的懸浮物質、膠體物質、生物單元流失的微生物菌群與已凈化的水分開。分離工藝簡單，占地面積小，出水水質好，一般不須經(jīng)三級處理即可回用。

5. It can effectively carry out solid-liquid separation, and separate the suspended matter, colloidal matter, microbial flora lost by biological units from the purified water. The separation process is simple, covers a small area, and the effluent quality is good. Generally, it can be reused without tertiary treatment.

6. 可使生物處理單元內(nèi)生物量維持在高濃度，使容積負荷大|大提高，使處理單元水力停留時間大|大的縮短，生物反應器的占地面積相應減少。

6. It can keep the biomass in the biological treatment unit at a high concentration, greatly increase the volume load, greatly shorten the hydraulic retention time of the treatment unit, and correspondingly reduce the floor area of the bioreactor.

7. 由于可防止各種微生物菌群的流失，有利于生長速度緩慢的(硝化等)的生長，從而使系統(tǒng)中各種代謝過程順利進行。

7. Because it can prevent the loss of various microbial flora, it is conducive to the slow growth (nitrification, etc.), so that various metabolic processes in the system can be carried out smoothly.

8. 使一些大分子難降解物的停留時間變長，有利于它們的分解。

8. The longer the residence time of some macromolecular refractory products is beneficial to their decomposition.

9. 膜處理技術與其它的過濾分離技術一樣，在長期的運轉過程中，膜作為一種過濾介質堵塞，膜的通過水量運轉時間而逐漸下降有效的反沖洗和化學清洗可減緩膜通量的下降，維持MBR系統(tǒng)的有效使用壽命。

9. Membrane treatment technology is the same as other filtration and separation technology. In the long-term operation process, the membrane is blocked as a kind of filter medium, and the water flow of membrane decreases gradually with the operation time. Effective backwashing and chemical cleaning can slow down the decline of membrane flux and maintain the effective service life of MBR system.
