UNITANK工艺特性及其设计与运行策略分析

Analysis on Technological Property of UNITANK and Strategy for Design and Operation

UNITANK采用了A/O工艺的空间结构,利用了SBR工艺的控制策略,但非优化设计的池体结构和池内显著的混掺现象,使其无法简单地按照某种模式运行,而需要根据进水情况、出水要求采用不同的运行策略甚至进行结构改良。因此,经过与A/O工艺和SBR工艺的对比及其运行实际分析,指出设计与运行UNITANK时,应将池体状态调整、池体结构改良和优势工艺相联合等。

UINTANK is designed as same to MO in spatial structure and to SBR in control strategy. UNITANK can not work only in some simple mode because of unoptimizable cell structure design and notable blending inside cells. Different operation strategies and even structure improvement should be executed according to the quality of influent and request on effluent. Modifying cell state, improving cell structure and joint dominant processes can be adopted for designing and running UNITANK based on comparing UNITANK with A/O and SBR and analysis on its use in practice.
