摘要:研究開發(fā)了一種新型的污泥濕式氧化處理工藝即SEUE-WAO工藝，并開展了規(guī)模為25 t/d（污泥含水率為80%）的生產性試驗。該工藝在高溫、高壓、富氧環(huán)境下對微生物細胞進行破壁，使得有機物發(fā)生水解和氧化反應而生成小分子有機酸、CO2和水，從而實現(xiàn)污泥的減量化、無害化和穩(wěn)定化；通過換熱反應一體化技術深度回收反應熱量，電耗≤60 kW·h/t（以濕泥計），在不添加化學藥劑的情況下脫水泥餅含水率<35%。同時，脫水泥餅的處置路徑靈活性強，可用于園林綠化以及包裝類紙板、陶粒和制磚等建材生產的原料添加物，也可以用于焚燒；分離液具有用作污水處理廠反硝化碳源的潛力。生產性試驗證明，該工藝具有超低能耗、安全可靠性高、環(huán)境友好、處理周期短、占地面積小、碳減排顯著等優(yōu)點。
Abstract:This paper developed a new sludge wet air oxidation process, namely SEUE-WAO process, and carried out a production test with scale of 25 t/d (sludge moisture content was 80%). The process broke the microbial cell walls in high temperature, high pressure and oxygen-rich environment, resulting in the hydrolysis and oxidation of organic matters to generate small molecular organic acids, CO2 and water, so as to achieve the reduction, harmlessness and stabilization of sludge. The reaction heat was deeply recovered through the integrated heat exchange-reaction technology. The power consumption was less than 60 kW·h/t, and the moisture content of the dewatered sludge cake was decreased to less than 35% without adding chemical agents. The disposal method of the sludge cake was flexible, which could be used for landscaping and incineration, and used as raw material additives for the production of packaging cardboard and building materials such as ceramsite and brick. The separation liquid had the potential to be used as denitrifying carbon sources in wastewater treatment plants. The production test showed that the process had the advantages of ultra-low energy consumption, high safety and reliability, environmental friendliness, short treatment cycle, small footprint area and significant carbon emission reduction.
