Leaching of vanadium presented in rock coal by Thiobadllus thiooxidans or T.ferrooxidans,including its extent,mechanism and affecting factors,was studied,recovering of vanadium from the leacheate also done.The results are shown as follows;1.By using calcium carbonate as an additive to burn rock coal,the rate of leaching of vanadium from the cinder by T.thiooxidans increased to 86%;While with no additive to burn rock coal,the rate of leading was only about 20%.It has been determined that,after having been burned,60% of sulfur in raw rock coal still remained in the cinder,thus,degree of pollution of sulfur dioxide to enviroment was lowered.2.By means of selecting the kind of rock coal and related conditions,even if no calcium carbonate additive was used,66% and 82% of vanadium from Runiao rock coal and its cinder by T.thiooxidans and 87% from the same rock coal by T.ferrooxidans could still be released respectively.3.The action of both strains on the release of vanadium mainly is indirect leaching.4.The present experiment recovered about 80% of vanadium from the leacheate by adopting the method of using ammonia water as a neutralizer and precipitant of leacheate at its first step,and the purity of vanadium pentoxide preparation was over 99%.As a result of the leaching and recovering,55-66% of total yield of vanadium has been obtained.

研究氧化硫硫杆菌和氧化铁硫杆菌浸出石煤中钒的作用强度、机理和条件,以及从浸出液提取钒的结果表明: 1.在燃用石煤中,采用碳酸钙作为添加剂,使氧化硫硫杆菌对燃烧后煤渣中钒的浸出率由未用添加剂的20%左右提高至86%,而且还使原煤中硫分的60%在燃烧之后仍旧留存于煤渣中,降低了二氧化硫气体污染环境的程度。 2.通过选择石煤的种类和有关的条件,则不用上述的添加剂碳酸钙,也可使氧化硫硫杆菌对鸬鸟石煤中钒的浸出率达到66%(原煤)和82%(煤渣);氧化铁硫杆菌则达到87%(原煤)。 3.这两种细菌浸出钒的作用主要为间接浸出作用。 4.采用先在浸出液中加氨水中和沉淀的提炼方法,钒的回收率达到80%左右,五氧化二钒制品的纯度可以高于99%。溶浸、提炼钒的总收得率达到55—66%。

From February, 1980 to July, 1981, occurrence and distribution of Saprolegniaceae in polluted water of Beijing district were investigated. Water samples were collected at regular intervals to isolate and determine the water mold in waterbodies with different degrees of pollution, ranging from Miyun Reservoir where water was relatively clean, to Chang River and Liangshui River with polysaprobic zones. The results revealed difference in ability of Saprolegniaceae fungi to tolerate pollution. Achlya sp. with low tolerance was abundant in oligosaprobic, less frequent in β-mesosaprobic, very rare in α-mesosapro-bic and absent in polysaprobic zone. On the contrary, Saprolegnia sp. with high tolerance occurred not only frequently in mesosaprobic to polysaprobic zones, but was the only saprolegniaceous fungi in polysaprobic zones. Aphanomyces sp., most prominent in clean water, was also occasionally isolated in polysaprobiczones, except in the mesosaprobic, and seemed to have greater adaptability to water environment. In addition, zoospores were few in clean water, but increased markedly in oligosaprobic and mesosaprobic zones with increasing pollution, and decreased almost to nil in polysaprobic zone with further addition of sewage and effluent. The results show that distribution and occurrence of saprolegniaceous fungi in various waterbodies seem probably to have rather close relation with the degree of pollution of the waterbodies and offer some usefulness in comprehensive evaluation of the water quality.

对北京地区水霉科真菌在不同污染水体中分布和数量变化的调查研究表明,水霉科游动孢子在水体中的数量随水体污染程度的变化而不同:一般在净水中较少,在轻度污染至中度污染的水体中明显增多,污染加重时逐渐下降,在重污染区明显减少,在近于毒污染的水体中则几乎绝迹.可见水霉科真菌在不同污染水体中的分布和数量变化具有一定的规律性,将其用作对水体进行综合评价的一项生物指标的可行性值得进一步研究.
