经过多年的运转实践说明同向流斜板沉淀有其独特的优越机能,但也发现同向流由于种种原因未能推广,例如板间积泥、集水孔眼堵塞、配水不均,施工困难以及斜板投资大等一些关键问题尚未解决。几年来国内试验与使用单位对以上问题的研究取得了不少进展,今年五月又在天津召开了该专题讨论会,为了总结经验,推荐较好的方案,提出如下几点商榷:一、同向流斜板沉淀器的构造经过几年来的试验与生产性运转,同向流斜板的基本形式除个别尚需推敲外,基本已趋一致,主要为:(1)板长:一般以2米为
After years of practice, it has been demonstrated that co-flow ramps have unique superior functions, but it has also been found that co-current flow cannot be promoted due to various reasons, such as mud accumulation between plates, clogging of water collection holes, uneven distribution of water, difficulty in construction, and Some key issues such as the large investment in ramps have not yet been resolved. Over the past few years, domestic research and use units have made a lot of progress in research on the above issues. In May this year, the symposium was held in Tianjin. In order to sum up experience and recommend better solutions, the following points of discussion were proposed: The structure of the flow inclined plate sedimentation device has been tested and productively operated for several years. The basic form of the co-current flow swash plate has basically converged except for a few individual requirements, mainly: (1) Plate length: generally 2 Mi Wei
