Papermaking wastewater mainly comes from pulping and papermaking processes in papermaking industry. Pulping is to separate the fibers from the plant raw materials, make them into pulp, and then bleach them. This process will produce a lot of papermaking wastewater. Papermaking is to dilute, shape, press and dry the pulp to make paper, which is easy to produce papermaking wastewater. The reclaimed water reuse system of papermaking wastewater mainly realizes the reuse of wastewater through four links: wastewater treatment station, regulating pool, microfiltration or ultrafiltration device, modified RO membrane filter device. After treatment, the recovered water quality is stable, meeting the requirements of "industrial water quality for urban wastewater recycling", meeting the factory standards, effectively saving a lot of water resources for enterprises and reducing production costs, It has solved the problem of energy conservation and emission reduction.

一. 設備簡介

1、 Equipment introduction

造紙廢水主要來自造紙工業生產中的制漿和抄紙兩個生產過程。制漿是把植物原料中的纖維分離出來,制成漿料,再經漂白,這個過程會產生大量的造紙廢水。抄紙是把漿料稀釋、成型、壓榨、烘干,制成紙張,這個過程也容易產生造紙廢水。 造紙廢水中水回用系統主要通過廢水處理站、調節池、微濾或超濾裝置處理、改性RO膜濾裝置處理四大環節實現廢水回用,經過處理后,回收水質穩定,達到《城市污水再生利用工業用水水質》要求,符合工廠標準,為企業有效節約大量水資源,降低生產成本,實實在在解決了節能減排的問題。

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、超濾系統和反滲透(RO)系統及EDI系統(可選)幾部分。由于廢水通過現代技術的深度處理能夠達到生產用水標準或者生活雜用水標準,使廢水能夠循環使用,這樣企業對于廢水這一塊的整體運行費用得到大|大的降低,對環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.

三. 工藝流程

3、 Process flow

四. 設計特點

4、 Design features

1. 系統采用全自動控制(同時亦可采用手動控制),系統運行時可設定自動反洗、再生程序;

1. The system adopts full automatic control (manual control is also available), and automatic backwashing and regeneration procedures can be set during system operation;

2. 管道一般采用UPVC材質;

2. UPVC material is generally used for pipes;

3. 集成控制系統和集成儀表系統等,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.
