一． 設(shè)備簡介

1、 Equipment introduction

造紙廢水主要來自造紙工業(yè)生產(chǎn)中的制漿和抄紙兩個生產(chǎn)過程。制漿是把植物原料中的纖維分離出來，制成漿料，再經(jīng)漂白，這個過程會產(chǎn)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(chǎn)生造紙廢水。 造紙廢水中水回用系統(tǒng)主要通過廢水處理站、調(diào)節(jié)池、微濾或超濾裝置處理、改性RO膜濾裝置處理四大環(huán)節(jié)實現(xiàn)廢水回用，經(jīng)過處理后，回收水質(zhì)穩(wěn)定，達(dá)到《城市污水再生利用工業(yè)用水水質(zhì)》要求，符合工廠標(biāo)準(zhǔn)，為企業(yè)有效節(jié)約大量水資源，降低生產(chǎn)成本，實實在在解決了節(jié)能減排的問題。

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.

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(hù)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. 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(jìn)行固液分離，將廢水中的懸浮物質(zhì)、膠體物質(zhì)、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(zhì)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.
