水质硫化物酸化吹气仪价格:4、具体实验建议():开启气源,(水和废水监测分析方法第四版,环保总局编)水浴温度控制在60℃~70℃,以400mL/min连续吹气50分钟。
5、具体实验建议(二):在做低浓度水质硫化物时,回收率偏低,建议方法:反应瓶本来取100毫升水样,现在取50毫升,在稀释到100毫升,开启气源,先吹5-10分钟,然后统以400mL/min连续吹气50分钟。
6、关于流量调节建议:水质硫化物-酸化吹气仪上面的7个分流量计(0-600毫升)在吹气时要统调到400毫升,*次调试需要将6个分流量计统调整好,以后做实验时,不用再调试6个小流量计(0-600毫升),如果下次做实验,6个小流量计(0-600毫升)可能会偏高(500毫升)或偏低(300毫升),这时应用高压氮气钢瓶上的减压阀进行缓慢调整或者用水浴锅上的大流量计(0-3升)进行统调整,将6个小流量计(0-600毫升)统调到400毫升即可。注:仪器面板7个流量计从左到右依次为1路分流量计,2路分流量计,3路分流量计,4路分流量计,5路分流量计,6路分流量计,总流量计。

公司介绍
The initial ammonia nitrogen content in the fresh waste water such as leather and animal excrement is not high, but the concentration of ammonia nitrogen will increase rapidly after the deamination reaction of nitrogen in the waste water is stored in the waste water or stays in the drainage pipeline for a period of time. The organic nitrogen industrial wastewater can be treated by biological method. While the microorganisms remove the organic carbon, the advanced oxidation converts the nitrogen in the wastewater into ammonia nitrogen through biological assimilation and biological mineralization. The treatment methods of ammonia wastewater include stripping, air stripping, ion exchange, activated carbon adsorption, biological nitrification and denitrification.
