23、,设有一个分建或合建生物选择器,壹序批曝气-非曝气方式运行的充-放式间歇活性污泥处理工艺,CASS工艺的反应器主要有生物选择区和主反应区两部分组成,根据实际需要也可在主反应区前设置兼氧区。生物选择区是设置在CASS前端的小容积区,通常在厌氧或兼性条件下运行,其基本功能是防止发生污泥膨胀,同时还具有促进磷的释放和强化反硝化作用。另外,在这个区内的难降解大分子物质易发生水解作用,这对提高有机物的去除有一定的促进作用。CASS工艺的特点:1、 CASS反应池由预反应区和主反应区组成,预反应区控制在缺氧状态,因此,提高了对难降解有机物的去除效果,不易发生污泥膨胀。2、 污泥沉淀性能良好,剩余污泥量相对
24、传统的活性污泥处理工艺少些。3、 抗水量水质变化冲击能力强,运行灵活。4、 CASS进水是连续的,进水管上无需电动控制阀等控制元件,单个池子可独立运行,自动化程度高,对自动控制装置的可靠性及运行和操作管理人员的素质要求高。9Unitank法 单纯的Unitank工艺,由三个矩形池组成,三个池水力想通,每个池内均有供氧设备,在外边两侧矩形池设有固定出水堰和剩余污泥排放口。中间池连续曝气,两侧池内间断曝气,交替作为沉淀池和曝气池。三个池交替的在缺氧、好氧和沉淀的状态下工作,通过自控程序,控制曝气器运转和改变进水点可使池中发生消化和反消化作用,在去除BOD5、SS的同时,达到生物脱氮目的。若在Uni
25、tank池前增设专门的厌氧池,可使其具备脱氮除磷功能。其优点是不需要污泥外回流、无专门的二沉池、布置紧凑、占地面积小。但设备的闲置率较高、利用率低,设备投资大,要求自动化程度极高。MSBR法MSBR法是一种改良型序批式活性污泥法,其实质是A2/O系统后接SBR,是二级厌氧、缺氧和好氧过程,连续进水、连续出水。因此,其兼具A2/O和SBR的特点,缺点是需要污泥回流和混合液回流,所需潜污泵较多,总容积利用率仅为73%,而且操作管理复杂,自动化程度要求极高。氧化沟法氧化沟工艺因其构造简单。易于维护管理,很快得到广泛应用。到目前为止已发展成为多种形式,主要有:PAssveer单沟型、Orbal同心圆型
26、、Carrousel循环折流型、D型双沟式和T型三沟式等。氧化沟池型具有独特之处,兼有完全混合和推流的特性,且不需要混合液回流系统,但氧化沟采用机械表面曝气,水深不宜过大,充氧动力效率地,能耗较高,占地面积较大。AB法 AB法是一种生物吸附降解两段活性污泥法,A段负荷高,曝气时间段,仅0.5h左右,污泥负荷高达2-6kgBOD5/kgMLSS.d,B段污泥负荷较低,为0.15-0.30kgBOD5/kgMLSS.d。该法对有机物。氮和磷都有一定的去除率,适用于处理浓度较高、水质水量变化较大的污水,通常要求进水BOD5350mg/L,AB法才有明显的优势。本工程设计进水BOD5不足200mg/L
27、,AB法显然也不太合适。HAF厌氧生物处理+FSBBR流离生物处理工艺HAF复合厌氧生物反应器是一个内部填充有供氧微生物附着的固定填料反应器。填料浸没在水中,微生物附着在填料上。废水从下部进入反应器,通过固定填料床,在厌氧微生物的作用下,废水中的有机物被厌氧分解。依靠填料使反应器内保有大量附着的生物膜以及截留大量的活性污泥,污泥浓度可达到10-20gVSS/L,SRT可达100天以上,同时反应器内各种不同的微生物自然分层固定,有利于各类微生物得到最佳的生态环境和平衡,实现更高的生物活性。该装置简单,不需要搅拌和回流污泥(必要时可出水回流),因而管理方便,能耗小;对废水浓度、温度及水量变化适应性
28、强,尤其适于处理各种浓度的废水。A/O/MBR工艺 膜-生物反应器工艺(A/O/MBR工艺)是膜分离技术与生物技术有机结合的新型废水处理技术,它利用膜分离设备将生化反应池中的活性污泥和大分子有机物质截留住,省掉二沉池。活性污泥浓度因此比一般工艺提高了,水力停留时间(HRT)和污泥停留时间(SRT)可以分别控制,而难降解的物质在反应器中不断的反应、降解。因此,膜-生物反应器工艺通过膜分离技术强化了生物反应器的功能,与传统生物处理技术相比,具有生化效率高,抗负荷冲击能力强,出水水质稳定,排泥周期长,比较容易实现自动控制等优点。MBR工艺描述任务2:处理工艺确定一、处理工艺SBR又称是序批式活性污泥
29、法。与传统污水处理工艺不同,SBR技术采用时间分割的操作方式,非稳定生化反应替代稳态生化反应,静置理想沉淀替代传统的动态沉淀。它的主要特征是在运行上的有序和间歇操作,SBR技术的核心是SBR反应池,该池集均化,初沉,生物降解,二沉等功能于一池,无污泥回流系统。 优点 :1.运行效果稳定,污水在理想的静止状态下沉淀,需要时间短、效率高,出水水质好。 2.耐冲击负荷,池内有滞留的处理水,对污水有稀释、缓冲作用,有效抵抗水量和有机污物的冲击。 3.工艺过程中的各工序可根据水质、水量进行调整,运行灵活。 4.处理设备少,构造简单,便于操作和维护管理。5.脱氮除磷,适当控制运行方式,实现好氧、缺氧、厌氧
