伴隨著我國城市化進(jìn)程的加快，國家對黑臭水體治理的不斷重視，雨污水管網(wǎng)運行養(yǎng)護(hù)工作要求越來越高，如何正確處理管網(wǎng)養(yǎng)護(hù)產(chǎn)生的大量通溝污泥成為亟待解決的問題。某市建成一套“淘洗+回收聯(lián)合利用”的通溝污泥處置設(shè)施，對該套處理設(shè)施半年多的運行情況進(jìn)行分析，發(fā)現(xiàn)通溝污泥中粒徑<0.2 mm的泥砂含量較高，對生產(chǎn)運行帶來一定的不利影響。通過分離通溝污泥中各種粒徑、不同類別的物質(zhì)，然后進(jìn)行分類處理，基本可以達(dá)到穩(wěn)定化、無害化和資源化的要求。

With the acceleration of urbanization in China, the country continues to attach importance to black and odorous water bodies. Thus stormwater and wastewater pipe network operation and maintenance work is becoming more and more demanding, and how to dispose the large amount of sewer sludge has become an urgent problem. A process of scouring and recycling combined utilization was established in a city. After analyzing the operation status of the treatment facilities for half a year, it was found that the silt content below 0.2 mm was relatively high in sewer sludge, which had a certain impact on the operation. Through separation of various particle sizes and different types of substances in the sewer sludge, and then classified treatment, the requirements of stabilization, harmlessness and resource utilization could be achieved.
