摘要/Abstract

摘要： 通过现场调查和试验以及室内多种模拟试验，揭示了机械、化学淤堵的形成条件与发展规律，以及生物淤堵成因及其对机械、化学淤堵的促进作用。在室内、外试验基础上根据工程经验提出了淤堵应对措施，包括根据淤堵溯源特性发明的过滤器可拆换式减压井，并通过工程应用证实了其有效性和可操作性。指出可以通过合理的设计、施工和运行管理使减压井尽可能避免淤堵，已淤堵者也可以通过一定措施恢复其功能，并建议推广应用过滤器可拆换式减压井。

Abstract: The results of site investigation and a series of tests in laboratory & in situ reveal the development condition and progress of physical, chemical and biological cloggings. On the basis of engineering practice and the revealed mechanism, a few treatment measures for clogging, including the relief well with a replaceable filter, are devised and tested in laboratory and in practical engineering. The results demonstrate that some of the treatment measures are effective and maneuverable. It is pointed out that relief well clogging could be avoided or mitigated under the conditions of reasonable design, construction and operation. The clogged wells could recover function again after being dealt with some measures. It is proposed to apply extensively the relief well with a replaceable filter.
