UASB反应器
设备简介：
UASB反应器废水被尽可能均匀的引入反应器的底部，污水向上通过包含颗粒污泥或絮状污泥的污泥床。厌氧反应发生在废水和污泥颗粒接触的过程。在厌氧状态下产生的沼气(主要是甲烷和二氧化碳)引起了内部的循环，这对于颗粒污泥的形成和维持有利。在污泥层形成的一些气体附着在污泥颗粒上，附着和没有附着的气体向反应器**部上升。上升到表面的污泥撞击三相反应器气体发射器的底部，引起附着气泡的污泥絮体脱气。气泡释放后污泥颗粒将沉淀到污泥床的表面，附着和没有附着的气体被收集到反应器**部的三相分离器的集气室。置于较其使单元缝隙之下的挡板的作用为气体发射器和防止沼气气泡进入沉淀区，否则将引起沉淀区的絮动，会阻碍颗粒沉淀。包含一些剩余固体和污泥颗粒的液体经过分离器缝隙进入沉淀区。
由于分离器的斜壁沉淀区的过流面积在接近水面时增加，因此上升流速在接近排放点降低。由于流速降低污泥絮体在沉淀区可以絮凝和沉淀。累积在三相分离器上的污泥絮体在一定程度上将**过其保持在斜壁上的摩擦力，其将滑回反应区，这部分污泥又将与进水**物发生反应。
UASB反应器构造：
UASB反应器包括以下几个部分：进水和配水系统、反应器的池体和三相分离器。
在UASB反应器中较重要的设备是三相分离器，这一设备安装在反应器的**部并将反应器分为下部的反应区和上部的沉淀区。为了在沉淀器中取得对上升流中污泥絮体/颗粒的满意的沉淀效果，三相分离器**个主要的目的就是尽可能有效地分离从污泥床/层中产生的沼气，特别是在高负荷的情况下，在集气室下面反射板的作用是防止沼气通过集气室之间的缝隙逸出到沉淀室，另外挡板还有利于减少反应室内高产气量所造成的液体絮动。反应器的设计应该是只要污泥层没有膨胀到沉淀器，污泥颗粒或絮状污泥就能滑回到反应室(应该认识到有时污泥层膨胀到沉淀器中不是一件坏事。相反，存在于沉淀器内的膨胀的泥层将网捕分散的污泥颗粒/絮体，同时它还对可生物降解的溶解性COD起到一定的去除作用)。只一方面，存在一定可供污泥层膨胀的自由空间，以防止重的污泥在暂时性的**或水力负荷冲击下流失是很重要的。水力和**(产气率)负荷率两者都会影响到污泥层以及污泥床的膨胀。UASB系统原理是在形成沉降性能良好的污泥凝絮体的基础上，并结合在反应器内设置污泥沉淀系统使气、液、固三相得到分离。形成和保持沉淀性能良好的污泥(其可以是絮状污泥或颗粒型污泥)是UASB系统良好运行的根本点。
UASB反应器附属设备
1、剩余沼气燃烧器：
一般不允许将剩余沼气向空气中排放，以防污染大气。在确有剩余沼气无法利用时，可安装余气燃烧器将其烧掉。燃烧器应装在安全地区，并应在其前安装阀门和阻火器。剩余气体燃烧器，是—种安全装置，要能自动点火和自动灭火。剩余气体燃烧器和消化池盖、或贮气柜之间的距离，一般至少需要15m，并应设置在容易监视的开阔地。
2、保温加热设备
厌氧消化像其他生物处理工艺一样受温度影响很大，厌氧工艺受温度影响更加显着。中温厌氧消化的较优温度范围从30～35℃，可以计算在20℃和10℃的消化速率大约分别是30℃下较大值的35%和12%。所以，加温和保温的重要性是不言而喻的。如果工厂或附近有可利用的废热或者需要从出水中间收效量，则安装热交换器是必要的。
3、监控设备
为提高厌氧反应器的运行可靠性，必须设置各种类型的计量设备和仪表，如控制进水量、投药量等计量设备和pH计(酸度计)、温度测量等自动化仪表。自动计量设备和仪表是自动控制的基础。对UASB反应器实行监控的目的主要有两个，一个是了解进出水的情况，以便观测进水是否满足工艺设计情况;另外一个目的是为了控制各工艺的运行，判断工艺运行是否正常。由于UASB反应器的特殊性还要增加一些检测项目，如挥发件**酸(VFA)、碱度和甲烷等。但是，这些设备属于标准设备，一些设备还很难形成在线的测量和控制。

upflow anaerobic sludge blanket
Introduction of equipment:
The UASB reactor wastewater is introduced into the bottom of the reactor as evenly as possible, and the *age flows upwards through the sludge bed containing granular sludge or floc sludge. Anaerobic reaction occurs in the process of contact between the waste water and the sludge particles. The biogas produced in the anaerobic state (mainly methane and carbon dioxide) causes internal circulation, which is beneficial to the formation and maintenance of granular sludge. Some gases formed in the sludge layer are attached to the sludge particles, and the attachments and unattached gases rise to the top of the reactor. The rise to the surface of the sludge impacted on the bottom of the gas launcher in the three-phase reactor, causing the sludge floc to degassed.  After the bubble is released, the sludge granules will be deposited on the surface of the sludge bed. The attached and unattached gas will be collected at the collector chamber of the three-phase separator at the top of the reactor. The role of baffle placed under the cell gap is the gas transmitter and the prevention of methane bubble entering the precipitating area, otherwise it will cause flocculation in the precipitating area, which will hinder particle sedimentation. The liquid containing some remaining solid and sludge particles enters the precipitate zone through the gap of the separator.
As the overflow area of the precipitate zone of the separator increases near the surface of the water, the rising velocity is reduced near the discharge point. The sludge floc can be flocculated and precipitated in the precipitation area due to the decrease of the flow rate. The sludge flocs accumulated on the three-phase separator will exceed the friction force on the inclined wall to a certain extent, which will slide back to the reaction area, and this part of sludge will react with the influent organic matter.
UASB reactor structure:
The UASB reactor consists of the following parts: water intake and water distribution system, tank body of reactor and three-phase separator.
The most important equipment in the UASB reactor is the three-phase separator, which is installed on the top of the reactor and divided the reactor into the lower reaction zone and the upper precipitation area. In order to achieve the rise in the precipitator flow of sludge floc particles / satisfactory effect of precipitation, three-phase separator first main purpose is as effectively as possible is separated from the sludge bed layer of methane produced, especially in high load conditions, the gas collecting chamber below the reflecting plate is to prevent through the gaps between the methane gas collecting chamber into a sedimentation chamber, in addition to the shield has caused by liquid floc reaction chamber gas dynamic yield. The reactor should be designed as long as the sludge layer is not expanded to the precipitator, and the sludge granules or floc can be slid back to the reaction chamber. It should be realized that sometimes the sludge layer expands to the precipitator, which is not a bad thing. On the contrary, the expansive mud existing in the precipitator will disperse the sludge particles / floc in the net, and at the same time, it will also play a certain role in the removal of biodegradable COD. On the one hand, there is a free space for expansion of sludge layer. It is important to prevent heavy sludge from being temporarily impacted under the impact of organic or hydraulic load. Both the water power and the organic (gas production) load affect the expansion of the sludge bed and the sludge bed. The principle of UASB system is based on the formation of sludge flocculating body with good settlement performance, and combined with sludge settling system in reactor to separate gas, liquid and solid three-phase. The formation and maintenance of sludge with good precipitation performance (which can be flocculated sludge or granular sludge) is the fundamental point of good operation of the UASB system.
UASB reactor accessory equipment
1. Residual methane burner:
The remaining methane is not allowed to be discharged into the air in general, in order to prevent the air pollution. When the residual methane is not available, the residual gas burner can be burned out. The burner should be installed in a safe area, and the valve and fireholder should be installed before it. The residual gas burner is a safety device that can be automatically ignited and automatically extinguishing. From the remaining gas burner and digestion tank cover, or between the gas storage tank, at least 15m, and should be set in the open to watch the.
2. Heat preservation and heating equipment
Anaerobic digestion, like other biological treatment processes, is greatly affected by the temperature, and the anaerobic process is more affected by the temperature. The optimum temperature range of medium temperature anaerobic digestion is from 30~35 degrees C, and the Digestibility Rate at 20 and 10 C is about 35% and 12% at the maximum value of 30 C, respectively. Therefore, the importance of heating and heat preservation is self-evident. It is necessary to install a heat exchanger if there is a waste heat that can be used in a factory or nearby or in the middle of the effluent.
3. Monitoring equipment
In order to improve the operational reliability of anaerobic reactors, various types of metering devices and instruments must be set up, such as metering devices such as water intake, dosage and other automatic meters, such as pH and acidity meter. Automatic measurement equipment and instrument are the basis of automatic control. There are two main purposes of monitoring the UASB reactor, one is to understand the situation of water import and export.
