为了使同向流斜板沉淀池的推广使用,我们成立了同向流科研组,从1977年6月至1979年9月,先后进行了现场试验和实验室试验,现简介如下。一、集水装置的试验研究我们分析了国内外现有集水装置的形式,研究了集水装置的基本原理,提出了二种新的集水装置——刀形(如图中a所示)和综合阻力型(如图中b所示)。通过现场试验和实验室试验,证明这二种集水装置比目前国内常用的梯形集水装置(如图中c所示)的出水水质要好些。这二种集水装置的主要技术特点是:
In order to promote the use of co-current flow swash-plate sedimentation tanks, we have established a research group for co-current flow. From June 1977 to September 1979, we conducted field tests and laboratory tests, which are summarized below. First, the experimental study of the water collecting device We analyzed the forms of the existing water collecting devices at home and abroad, studied the basic principle of the water collecting device, and proposed two new water collecting devices—knife shape (as shown in a) ) and comprehensive resistance type (shown in figure b). Through on-site tests and laboratory tests, it was proved that these two types of water collection devices are better than the effluent quality of the commonly used trapezoidal water collection devices (shown in figure c). The main technical features of these two water collection devices are:
