摘要
伴隨著城市化進(jìn)程加快與工業(yè)迅速發(fā)展,產(chǎn)量日益增加的污泥已對(duì)城市生態(tài)環(huán)境造成極其嚴(yán)重的威脅。為了有效地消除這種環(huán)境衛(wèi)生公害,并且促進(jìn)其資源化,提出了采用超聲波技術(shù)進(jìn)行污泥處理之建議,在總結(jié)國(guó)內(nèi)外相關(guān)研究現(xiàn)狀的基礎(chǔ)上歸納出該技術(shù)的三大主要優(yōu)勢(shì):殺菌、除臭、提高污泥穩(wěn)定性;污泥減量效果顯著;促進(jìn)污泥中氮、磷量的增加,有利于污泥資源化;改善污泥絮凝脫水性能。最后指出了目前國(guó)內(nèi)該技術(shù)所急需解決的問(wèn)題,以明確今后的研究方向與重點(diǎn)。
Abstract
With the quick urbanization and development of industry,the ecology and environment in cities are subjected to the extremely serious threat leaded by the more and more increasing production of sludge. In order to effectively eliminate such environmental pollution as the sludge, and promote its utilization, an advice of application of ultrasound technique in sludge treatment is put forward. Based on the present status about domestic and foreign study of ultrasonic treatment of sludge,three main advantages of ultrasound technique are concluded,such as disinfect pathogens, deodorizing, sludge stabilization improving and remarkable dewatering,increase of the nitrogen and phosphorus content in sludge for its much better utilization. In addition, the present problems needed to be solved urgently for this technique in our country are pointed out,as the directions and keys for the further study of ultrasonic treatment of sludge.
