          如何設計化糞池

          來源:http://www.ztkygs.com  發布時間:2022-02-05 21:29:26

            化糞池前排管長度規范沒定死,但要考慮:
           
            The length of the front pipe of the septic tank is not fixed,but it should be considered:
           
            1、坡度;
           
            1.Slope;
           
            2、管徑。
           
            2.Pipe diameter.
           
            總的原則,能流到化糞池即可,不考慮臭氣
           
            The general principle is that it can flow to the septic tank without considering the odor
           
            糞池前的管道坡度不小于0.006至于池前管道長度,對于小區來說是不存在問題的,環保局規定在污水處理廠5公里以內的建筑可以不用設計化糞池,直接排入市政管網,其實也是限制了化糞池前的管道長度
           
            The slope of the pipeline in front of the septic tank shall not be less than 0.006.As for the length of the pipeline in front of the tank,there is no problem for the community.The Environmental Protection Bureau stipulates that buildings within 5km of the sewage treatment plant can be directly discharged into the municipal pipe network without designing septic tanks.In fact,it also limits the length of the pipeline in front of the septic tank
           
            如果按照居住小區設計規范做成7%的坡度,實在太大了。根據工程現狀來,有條件就做大點。
           
            If we make a slope of 7%according to the design specifications of residential quarters,it is too big.According to the current situation of the project,expand it if possible.
           
            原則上HC前的污水管長度應盡可能短,因此HC的位置確定很關鍵,應綜合考慮地勢高差和總平條件等因素后,爭取各支線的長度盡可能平衡。必要時可拆分HC容量,盡管造價會有所增加,但可避免HC前的污水管過長可能導致的固液離析,造成堵塞。一般情況下,使用塑料等水力特性較好的管材,HC前的污水管長度控制在100m以內為宜。
           
            In principle,the length of the sewage pipe in front of HC should be as short as possible,so it is very important to determine the location of HC.After comprehensively considering the factors such as terrain elevation difference and general leveling conditions,strive to balance the length of each branch line as much as possible.If necessary,the HC capacity can be split.Although the cost will increase,it can avoid the solid-liquid separation and blockage caused by the long sewage pipe in front of HC.Generally,pipes with good hydraulic characteristics such as plastics should be used,and the length of sewage pipe in front of HC should be controlled within 100m.
           
            為防止糞液對地下水和周圍環境造成污染,設計化糞池(貯糞池)其四壁和池底應做防水處理,池蓋必須堅固(特別是可能行車的位置)、嚴密合縫,檢查井、吸糞口不宜設在低洼處,以防雨水浸入。化糞池(貯糞池)宜設置在人們不經常停留、活動之處。化糞池應遠離地下取水構筑物。
           
            In order to prevent the fecal liquid from polluting the groundwater and the surrounding environment,the septic tank(septic tank)shall be designed,and its four walls and bottom shall be waterproof.The tank cover must be firm(especially at the position where driving may be possible)and tightly jointed.The inspection well and fecal suction port should not be set in low-lying places to prevent rainwater immersion.Septic tank(septic tank)should be set at places where people do not stay and move frequently.Septic tanks shall be kept away from underground water intake structures.
           
            化糞池應根據使用人數和清掏周期選擇設計合適的容積。
           
            The septic tank shall be designed according to the number of users and cleaning cycle.
