结合工程实例介绍了设截留池法、溢流井排放法和管道穿井法3种在声测管厂家道设计中可减少管道埋深的处理方法,并对各种方法的适用条件,设计中需要注意的问题及相关设计参数的取 值作了具体的说明。
This paper introduces the design method of interception basin, overflow well discharge method and pipe wear well method 3 kinds of test tube method can reduce the depth of some factory in the design of the sound, and the applicable conditions of each method, the value of the problems and the relevant design parameters in the design in detail.
原理:该方法在污水排放系统中采用截留池拦截污水 中容易沉淀的物质,以防止因声测管厂家管道坡度减小和流速降低而引起的管道堵塞,从而酌情减小声测管厂家道最小设计流速和最小设计坡度的取值,以达到减小声测管厂家道埋深的目的。在具体设计时,可采用普通化粪池作为截留池。因截留池主要拦截污水中的易沉淀物,不需厌氧发酵净化污水,所以在容量计算时,污水部分的容积可取正常化粪池的1/3,而整个截留池的容积约为正常化粪池的1/2。在设计污水声测管厂家管道时,截留池前的管道坡度不能减小,经截留池防淤处理后的污水声测管厂家管道,其最小设计流速和最小设计坡度的取值,可比规范规定的最小值减小20%~30%。该方法适用于地势平坦,且声测管厂家管道起点(控制点)离市政污水管网的接入点距离较长的住宅小区或厂区。
Principle: by this method is easy to precipitate in the sewage interception interception basin of substances in the sewage system, to prevent the acoustic pipe manufacturers reduce the pipeline slope and reducing the flow rate caused by the blockage of the pipeline, thereby reducing the pipe factory value in appropriate financial minimum design flow and minimal design slope, in order to reduce the acoustic tube some depth to plant. In the concrete design, the common septic tank can be used as the retention tank. Because the pool in the sewage interception interception is easy to precipitate, without anaerobic fermentation of sewage purification, so in the calculation of capacity, the volume of sewage of desirable normal septic 1/3, while the interception pool volume is about normal septic 1/2. The pipe manufacturers in the design of sewage pipeline sound, interception pipeline not pool in front of the slope decreases, the interception of prevention and treatment of sewage pool acoustic pipe pipe manufacturers, the minimum value of the design flow and minimum design gradient, comparable standard minimum value is reduced by 20% ~ 30%. The method is applicable to a residential area or a factory area with a longer distance from the municipal sewage pipe network and the starting point (control point) of a sound measuring pipe manufacturer.
