一．    设备简介

One Equipment introduction

日化品厂产生的废水量一般都不会很大，但是这些废水中的污染浓度非常高，就算日化品的生产量再大，它的废水因为日化品生产工序的原因导致废水的产生量也不会太大，不过其水量和水质的起伏也比较大不规律，不止如此废水中的LAS和COD的浓度也比一般的水质高出很多，其水中的活性剂在水中的存货量非常的少因此另一方面也会造成破坏水质的张力。如果遇到生物处理时活性剂又不得超过1000mg/L，因为生物处理工艺在遇到有毒物质在好氧的阶段会产生大量的泡沫；而中水回用他是一体化全自动的生物膜反应器，也叫MBR设备它的生物处理技术可完全代替了传统的中水处理工艺，其可从进水到达标出水一体达成，可大|大的减少用地面积和人工，而且出水稳定易操作可的去除水中的各种有毒物质和，产出污泥量非常少，而水中的悬浮物质几乎接近零排出，还含有消毒杀菌的作用，直接处理到中水达标的标准。

The amount of waste water produced by daily chemical products factories is generally not very large, but the pollution concentration of these waste water is very high. No matter how large the production volume of daily chemical products is, the amount of waste water produced due to the production process of daily chemical products will not be too large, but the fluctuation of water quantity and quality is relatively large and irregular, More than that, the concentration of LAS and COD in wastewater is much higher than the general water quality, and the inventory of active agent in water is very small, so on the other hand, it will cause the tension of damaging water quality. In case of biological treatment, the active agent should not exceed 1000mg/L, because the biological treatment process will produce a large amount of foam when it meets toxic substances in the aerobic stage. The reclaimed water reuse is an integrated automatic biofilm reactor, also known as MBR equipment. Its biological treatment technology can completely replace the traditional reclaimed water treatment process. It can be achieved from the inlet water to the standard outlet water. It can greatly reduce the land area and manpower, and the effluent is stable and easy to operate. It can remove all kinds of toxic substances and pollutants in the water, and produce very little sludge, The suspended matter in the water is almost zero discharge, and it also has the function of disinfection and sterilization, which can be directly treated to the standard of reclaimed water.

J9九游国际真人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。

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.

4. 设备具有耗材更换自动提示功能，并且耗材的更换周期取决于水质和压力的变化，而非根据耗材的使用时间，考虑到了各地水质的差异，设计更；

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. 能有效地进行固液分离，将废水中的悬浮物质、胶体物质、生物单元流失的微生物菌群与已净化的水分开。分离工艺简单，占地面积小，出水水质好，一般不须经三级处理即可回用。

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. 可使生物处理单元内生物量维持在高浓度，使容积负荷大|大提高，使处理单元水力停留时间大|大的缩短，生物反应器的占地面积相应减少。

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. 由于可防止各种微生物菌群的流失，有利于生长速度缓慢的(硝化等)的生长，从而使系统中各种代谢过程顺利进行。

8. 使一些大分子难降解物的停留时间变长，有利于它们的分解。

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

9. 膜处理技术与其它的过滤分离技术一样，在长期的运转过程中，膜作为一种过滤介质堵塞，膜的通过水量运转时间而逐渐下降有效的反冲洗和化学清洗可减缓膜通量的下降，维持MBR系统的有效使用寿命。

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.
