    摘要:
    因为当地污泥措置能力不足,今朝深圳市仍有约60%的污泥外运措置,运输距离远,措置价钱高。2019年头,深圳福永水质净化厂将离心脱水后含水率80%的污泥输送至183 km外的华润电力海丰电厂进行掺烧,总本钱约62 352 元/d。2019年5月起,该厂污泥深度脱水应急项目最先实行,采取能与近况离心脱水系统相跟尾的深度脱水带式机,经由过程药剂调度和机器压榨,将污泥含水率从80%降至60%,污泥外运量从120 t/d降至68.3 t/d,减量结果显著。在污泥减量的同时,污泥的处置措置总本钱也降至44 315 元/d,经济效益较着。另外,深度脱水后的污泥从团状塑态变成片状半固态,有益在进行长距离运输和电厂协同措置,污泥热值从-0.96 MJ/kg升至0.69 MJ/kg。该污泥深度脱水应急项目已不变运转一年多,其设想和运转经验具有必然的鉴戒意义。
    Abstract:
    Due to the lack of local sludge disposal capacity, about 60% of the sludge in Shenzhen is still exported for disposal, which means a long transportation distance and high disposal price. At the beginning of 2019, Shenzhen Fuyong WWTP transported the sludge with a water content of 80% after centrifugal dewatering to China Resources Power Haifeng Power Plant, which is 183 km away, for mixed burning with a total daily cost of about 62 352 yuan. Since May 2019, the emergency project for deep dewatering of sludge has been implemented. The deep dewatering belt dehydrator that can be connected with the current centrifugal dewatering system has been used to reduce the sludge water content from 80% to 60% and reduce the sludge transport volume from 120 t/d to 68.3 t/d through chemical conditioning and mechanical pressing with significant reduction effect. Besides, the total cost of sludge treatment and disposal has also decreased to 44 315 yuan/d, with obvious economic benefits. In addition, the appearance of the sludge after deep dewatering changes from a lumpy plastic state to a sheet?like semi?solid state, which is conducive to long?distance transportation and power plant co?processing. The calorific value of sludge increased from -0.96 MJ/kg to 0.69 MJ/kg. The emergency project of sludge deep dewatering has been running stably for over a year, whose design and operation experience can provide references.
