天津南开造纸废水处理
造纸废水处理主要采用物流处理、化学氧化处理和生物处理这三种方法,具体如下:
1.造纸废水处理-物理处理法
主要有吸附法、絮凝法、电渗析和超声波膜等几种方式。吸附法主要采用黏土吸附法、粉煤灰吸附法、活性炭吸附法和水解吸附法等。絮凝法主要采用无机高分子絮凝剂、有机高分子絮凝剂和天然有机高分子絮凝剂等。电渗析是一种以电位差为推动力,利用离子交换膜的选择透过性,从溶液中脱除或富集电解质的膜分离操作。超声波膜电解方法能明显提高造纸废水的回收处理效果。
2.造纸废水处理-化学氧化处理法
主要有水热氧化法、光催化氧化、湿式氧化法、化学氧化法和电化学氧化法等。
3.造纸废水处理-生物处理法
生物处理法可分为好氧生物处理法和厌氧生物处理法
好氧生物处理法是在有氧条件下,借助好氧微生物(好氧菌)的作用来降解污染物的方法。造纸废水含大量有机物,可生化性好,用好氧生物处理造纸废水一般可得到很好的效果。厌氧生物处理是利用兼性厌氧菌和专性厌氧菌在无氧的条件下降解有机污染物的处理技术。厌氧法适用于石灰草浆蒸煮废液、碱法制浆废水等。

Tianjin Nankai papermaking wastewater treatment
The three methods of papermaking wastewater treatment mainly include logistics treatment, chemical oxidation treatment and biological treatment, which are as follows:
1. treatment of papermaking wastewater by physical treatment
There are several main methods such as adsorption, flocculation, electrodialysis and ultrasonic film. The adsorption method mainly adopts clay adsorption method, fly ash adsorption method, activated carbon adsorption method and hydrolytic adsorption method. The flocculation method mainly adopts inorganic polymer flocculant, organic polymer flocculant and natural organic polymer flocculant. Electrodialysis is a membrane separation operation by removing or enriching electrolytes from the solution by using the selective permeability of the ion exchange membrane with the potential difference as the driving force. The method of ultrasonic membrane electrolysis can obviously improve the recovery and treatment effect of papermaking wastewater.
2. papermaking wastewater treatment chemical oxidation treatment
There are mainly hydrothermal oxidation, photocatalytic oxidation, wet oxidation, advanced chemical oxidation and electrochemical oxidation.
3. papermaking wastewater treatment biological treatment method
Biological treatment can be divided into aerobic biological treatment and anaerobic biological treatment
Aerobic biological treatment is a method of degradation of pollutants with the aid of aerobic microorganisms (aerobic bacteria) under aerobic conditions. The papermaking wastewater contains a large amount of organic matter, and it is good for biodegradability. The treatment of papermaking wastewater with aerobic organism can get good results. Anaerobic biological treatment is a treatment for the degradation of organic pollutants under anaerobic conditions by the use of facultative anaerobes and specific anaerobes. The anaerobic method is suitable for the waste liquid of lime straw pulp cooking, alkali pulping wastewater and so on.
