组合式固液分离器在一体化氧化沟中的应用

Application of the Combined Solid-liquid Separator to Integrated Oxidation Ditches

组合式固液分离器利用沟内污泥网捕、过滤动态分离与沟内沉淀静态分离相结合的机理,有较好的固液分离效果和防止污泥上浮的功能,不仅实现了一体化氧化沟污泥自动回流,而且保证了一体化氧化沟出水SS≤20 mg/L,达到了《城镇污水处理厂污染物排放标准》(GB18918-2002)一级B标准,有应用价值。

The combined solid -liquid separator making use of the Dynamic separation and Static separation Mechanism,presents a better function in Solid - liquid separating and preventing sludge from rising. The sludge of built - inside ditch can format a sludge level,which can capture the sludge as a net and has Sedimentation function. It can not only achieve the Sludge automatic backflow, but also ensure that the SS of effluent of Integrated Oxidation Ditches is less than 20mg/L. The effluent quality complies with Level 1B standard stipulated in the Discharge Standard of Pollutants for Municipal Wastewater （GB18918 -2002）. This combined solid -liquid separator has application value.
