摘要
在较大浊度范围内进行了太阳辐射透射率实验。实验表明浊度对太阳能在水中的辐射透射影响很大,浊度为8.1ntu的苦卤在水下50cm太阳辐射透射率仅为0.08。进行了苦卤的降浊处理和降浊后苦卤中浮游藻类的再滋生实验。实验表明絮凝降浊对苦卤中藻类的生长有一定的抑制作用,但经过一段时间可能会突然迅速滋生蔓延,并使太阳池内的浊度大幅增加。进行了苦卤太阳池水浊度的研究实验,发现苦卤水中的浊度并不向上层扩散,故不必对底层的苦卤进行降浊处理;发现尘土落入纯盐水中可较快沉降,而在苦卤中沉降速度很慢,很难自然澄清。
The solar transmissivity of the water in large range of turbidity has been meosured. The results indicated that the turbidity of the water has significant influence on the solar transmissivity, the solar transmissivity in bittern where the turbidity is 8.1 ntu is only 0.1 in 50cm below the surface. The experiments of turbidity reduction and tested regrowth of the algae to some extend by using flocculants to reduce the turbidity of the bitten, but after a period of time, the algae may greatly propagate, and the turbidity of the solar pond greatly increases. The turbidity doesn＇t diffuse upward, so it is not necessary to reduce the turbidity of the lower convective layer; the dust can subside quickly when it falls in the pure salt pond, but it subsides slower in bittern pond, so the water of bittern can＇ t be clarified easily.
