In the progress of the Four-modernization movement, the sewerage systems of the cities will be modernized. The selection of the disposal methods of municipal sewage and the way of seperation of the old combined sewerage system need to be discussed and studied. This article points out the rationality of the method of ir- rigation and possibility of developing new concepts and principles for storm and sanitary sewer design to promote the seperation of old combined swerage system.

This method has the advantages of high efficiency and low cast, so it suit coastal industries for their sewage disposal. The influence of arsenic content, the valency state of arsenic, magnesium salt content, the ratio between magnesium and arsenic and the nature of the medium upon dearsenization has been examined.

A new method of dearsenization polluted water by means of magnesium salts from seawater is developed-dearsenization by Magnesium Salts. This method has the advantages of high efficiency and low cast, so it suit coastal industries for their sewage disposal. The influence of arsenic content, the valency state of arsenic, magnesium salt content, the ratio between magnesium and arsenic and the nature of the medium upon dearsenization has been examined. The most favorable condition for dearsenization were. found to be pH 9.5-10.5, Mg: As 8-12. Polluted water containing arsenic as high as 600 mg/l can be dearsenized with the efficiency of more than 99%. Trivalent arsenic appears to be dearsenized less easily than pentavalent arsenic. In order to decrease the amount of magnesium salt used and improve the efficiency of dearsenization, technological processes of stepwise dearsenization by magnesium saits, dearsenization by magnesium salts after the trivalent arsenic being oxidized and the removal of the residual arsenic by magnesium salts containing Fe or phosphate were studied. Conditions for dearsenizing polluted water containing about 200 mg As/l to an arsenic content conforming that of the national standard (0. 5 mg As/l) were obtained. An enlarged experiment on a 5 lsample was also made with the same satisfa- ctory resoult. Aiming at minimizing environmental pollution by way of "disposing of wastes by wastes", experiments using the waste residue discharged from soda plants-to the sea-caustic mud-to take the place of lime in dearsen- ization have also been carried out. Results prove that caustic mud not only can satisfactory take the place of lime, but also lowers the cost and increases the efficiency of dearsenization. Instead of magnesium salts from seawater, the by-product from salt- works, solid bitterm, has also been used. Satisfactory results of dearsenization have also been obtained.Thus, it is made possible for the inland plants, where sea-water is hardly avaliable, to dearsenize arsenic-containing wastewater by magnesium salts.

本试验研究了一种利用价廉易得的海水中的镁盐来脱除污水中无机砷的新方法──镁盐脱砷法。试验结果表明;脱砷比较彻底,成本也较低廉,很适于临海工厂使用。 试验考查了污水中砷含量、砷的价态、镁砷比以及介质条件等因素对脱砷效果的影响。找出了在pH为 9.5-10.5,镁砷比为8-12时脱砷效果最好。三价砷比五价砷较难脱除。利用分段镁盐脱砷、氧化镁盐脱砷及混合镁盐脱砷均可降低镁盐用量和提高脱砷效率。同时,还进行了五升规模的扩大试验。 试验还考查了利用碱厂废渣苛化泥代替石灰及利用盐场副产的卤块代替海水提供镁盐来进行脱砷,也获得了同样良好的脱砷效果。

The sewage-sludge treatment industry has had great development at home and abroad since 1970's. In the present paper, the disposal technology, comprehensive utilization aod the main economic target for the sludge treatment coming from the main developed countries in the world and our country, are introduced by the author.

70年代以来,世界城市污水、污泥处置有了很大发展。本文以各主要工业发达国的污水厂及国内已投产的城市污水厂的污泥处置为依据,对其处置工艺、综合利用情况、及主要经济指标作了一定的介绍。
