摘要:- 為了延長(zhǎng)污水管道的使用壽命、減少管道沖洗成本、降低人工養(yǎng)護(hù)風(fēng)險(xiǎn)、提高污水管網(wǎng)管理水平，設(shè)計(jì)了一種水力沖洗小管徑倒虹吸
管道的方法，并研究了倒虹吸管段流速與污泥沉淀量的關(guān)系、蓄水沖洗前后倒虹吸管段流速的變化、攔蓄水量與倒虹吸管段沖洗效果的關(guān)系、沖洗頻率與倒虹吸管段沉淀量的關(guān)系。結(jié)果表明，隨著流速的增大，污泥沉淀量出現(xiàn)逐漸降低的趨勢(shì)；隨著攔蓄盾攔蓄水位的升高，倒虹吸管段的流速也逐漸增大，超過(guò)55 cm時(shí)，流速上升趨勢(shì)變緩；當(dāng)攔蓄水位在50~55 cm之間時(shí)，倒虹吸管段污泥濃度的去除率明顯升高，最優(yōu)攔蓄水位為55 cm；設(shè)備的最優(yōu)沖洗頻率為3次/d；自沖洗設(shè)備對(duì)管道中的漂浮物和懸浮物具有非常好的去除效果。
Abstract:- In order to extend service life of sewage pipelines, reduce pipeline flushing costs and the risk of manual maintenance, and improve the management level of sewage pipelines, a method for hydraulic flushing of small diameter inverted siphon was designed, and relationship between flow velocity of the inverted siphon pipeline and content of sludge sedimentation, variations in flow velocity of the inverted siphon pipeline before and after water storage and flushing, relationship between water storage and flushing performance of the inverted siphon pipeline, and relationship between flushing frequency and sedimentation content of the inverted siphon were explored. With the increase of flow velocity, the amount of sludge sedimentation tended to be a gradual decreasing trend. As the water storage capacity of the intercepting shield increased, the flow velocity of the inverted siphon pipeline gradually increased. When the water level exceeded 55 cm, the flow velocity increased slowly. When the interception water level was between 50 cm and 55 cm, the removal efficiency of sludge concentration in the inverted siphon pipeline increased obviously. Therefore, the optimal water level was 55 cm, and the optimal flushing frequency of the device was 3 times/day. Self-flushing equipment had a very good removal performance on floating and suspended matters in the pipeline.
