A new-type water treatment construction to be called air-floated filter can combine the air-floation and filtration into one working process. It is of high efficiency in water treatment, covers less land for building, lower in cost, more ecormomical in operation and easy in management This paper has made a brief introduction to the result of the experiment in three stages as well as its application in production. Based on the data of experiments, the mechanism of air-filtration has been further discussed. Productive practice shows that quite satisfactory for air-floated filter to treat the raw water with a large number of algae, which is similar to the lake water slightly polluted by organism.

Abstract A new grating tester is described which can test grating discs in small diameter with 2400 slits, High precision static air-floating bearings are used in this tester. The dividing criteria are based on Moire patterns formed by the grating. The photo-electric conversion is performed by silicon photocell sets, and the measuring signals are picked up with two sentors placed on both end of a diameter. Then a double phasecomparision circuit processes the signals, and the error curves are given...

Abstract A new grating tester is described which can test grating discs in small diameter with 2400 slits, High precision static air-floating bearings are used in this tester. The dividing criteria are based on Moire patterns formed by the grating. The photo-electric conversion is performed by silicon photocell sets, and the measuring signals are picked up with two sentors placed on both end of a diameter. Then a double phasecomparision circuit processes the signals, and the error curves are given on the recorder. In addition, there is the digital display of error on the front panel. This grating tester is characterized by its size, high aceuracy, high efficiency and convenience of use.

本文介绍了一种检测小直径粗线条光棚盘的仪器。该仪器采用了高精度空气静压气浮轴承,以光栅莫尔条纹作为分度基准,用多个硅光电池进行光电转换,用对径双头读数器拾取被测信号,用双比相电路处理相号。记录器给出误差曲线,并以面板表数字显示误差数值。仪器体积小,精度高,使用方便,工作效率高。

In the process of floatation treatment of Cr-contg. wastewater, ferrous sulphate is used as reducer to reduce hexa-valent chromium into tri-valent chromium, and then air floating is conducted. However it is not satisfactory due to the heavy and complicated operation, great consumption of ferrous sulphate and large quantity of sludges. The collector "RM", a fatty organic compound, after dissolving in acetic acid, is therefore tested as a reactant to treat Cr-contg. plating wastewater and has some advantages,...

In the process of floatation treatment of Cr-contg. wastewater, ferrous sulphate is used as reducer to reduce hexa-valent chromium into tri-valent chromium, and then air floating is conducted. However it is not satisfactory due to the heavy and complicated operation, great consumption of ferrous sulphate and large quantity of sludges. The collector "RM", a fatty organic compound, after dissolving in acetic acid, is therefore tested as a reactant to treat Cr-contg. plating wastewater and has some advantages, as it acts directly with Cr~(6+) without any reducing agent. It is favourable to be popularized, because it is much cheaper than quaternary ammonium. Tests have been carried out on pH value, collector dosage and effects of co-existant ions.Results show that the contents of Cr~(6+) and Cr~(3+) after treatment are both within the limits of pollution control, when Cr~(6+) concentration>20mg/L, and pH 2-5, with 0.004M RM, Cr/RM=0.8.

本文用RM气浮剂,对电镀含铬废水进行了气浮法处理的实验室研究。该方法对酸性格(Ⅵ)废水,可直接加药后进行气浮分离铬(Ⅵ),不用调pH,不加还原剂。RM药剂比季铵盐便宜得多,设备简单,投资较少,处理后废渣量少,便于进一步处理与回收。
