在水池的设计过程中,设计和施工单位往往比较重视设计和整个施工过程,而对于最后的满水试验不给予足够重视,试验无方案,易引起工程质量事故。一、污水处理工程概况某化工生产企业污水处理厂日处理污水400M3/d,根据工艺设计,共有六个池体和一个设备用房,池体的体积和埋深均不一致。由于场地限制,其整个平面布局非常紧凑,具体平面布置见下图1:各池体体量及埋深见下表1。二、污水处理工程地质情况根据地勘报告,地下水为上层滞水,土层分布不均匀,厚薄不一,特别是在表层素填土下,不均匀分布一层厚度约2～3米左右的淤泥。各土层分布状况几物理力学指标见表2。
In the design process of the pool, the design and construction units tend to pay more attention to the design and the whole construction process. However, they do not pay enough attention to the final full water test, and have no plan to test and easily lead to engineering quality accidents. First, the overview of sewage treatment works A chemical production plant sewage treatment plant sewage treatment 400M3 / d, according to process design, a total of six pools and a room equipment, pool volume and depth are not the same. Due to site constraints, the entire plane layout is very compact, the specific layout shown in Figure 1 below: The body volume and depth of the pool shown in Table 1 below. Second, the geological conditions of sewage treatment According to geological survey report, groundwater is the upper stagnant water, soil uneven distribution, the thickness varies, especially in the surface layer fill, the uneven distribution of a thickness of about 2 to 3 meters of mud . The distribution of several soil physical and mechanical indicators in Table 2.
