Description
技术领域: Technical field:
本实用新型涉及有机废水处理回用管式膜生物反应装置。 The utility model relates to a tubular membrane biological reaction device for organic waste water treatment and reuse. the
背景技术: Background technique:
目前的膜生物反应器绝大多采用“浸没式中空纤维膜组件”膜组件安放在生化池内,采取抽吸式过滤,通过自吸泵或真空抽吸,源水透过中空纤维膜而实现固液分离净化,由于抽吸式工作变量控制小,只有8-12L/m2·h,流量相对较低,且由于膜组件长时间浸泡在拥有大量微生物的污水中,具有生成生物污染的风险,化学清洗时,只能离线进行,这不利于大规模连续稳定运行,膜组件寿命短,一般只有1-2年。 Most of the current membrane bioreactors use "submerged hollow fiber membrane module" membrane module placed in the biochemical pool, adopt suction filtration, through self-priming pump or vacuum suction, the source water passes through the hollow fiber membrane to achieve solid-liquid Separation and purification, due to the small control of the suction working variable, only 8-12L/m2·h, the flow rate is relatively low, and because the membrane module is immersed in the sewage with a large number of microorganisms for a long time, there is a risk of biological pollution, chemical cleaning It can only be done offline, which is not conducive to large-scale continuous and stable operation, and the life of the membrane module is short, generally only 1-2 years. the
一般的外置式膜生物反应器是将膜装置于生化池外放置。生化池的原水通过给水泵和循环泵使膜装置与生化池连续在一起。透过液至清水池,浓水返回生化池,由于生化池中的混合液悬浮固体浓度很高。为防止膜组件污堵,这种外置式膜生物反应器必须采用大错流形式进行固液分离,为达到每秒1-3米的过滤速度,通常循环水量和产水量的比例达到10∶1,即生产1吨透过液,需要10吨的原水循环水量,这种大错流的电耗通常要达到3-5度电/吨水,明显的是高能耗。 The general external membrane bioreactor is to place the membrane device outside the biochemical pool. The raw water in the biochemical pool is connected to the membrane device and the biochemical pool through the feed water pump and the circulation pump. The permeate is sent to the clear water tank, and the concentrated water is returned to the biochemical tank, because the mixed liquid in the biochemical tank has a high concentration of suspended solids. In order to prevent fouling of membrane modules, this external membrane bioreactor must adopt a large cross-flow form for solid-liquid separation. In order to achieve a filtration speed of 1-3 meters per second, the ratio of circulating water to produced water is usually 10:1. , that is, to produce 1 ton of permeate, 10 tons of raw water circulation is required. The power consumption of this large cross-flow usually reaches 3-5 kWh/ton of water, which is obviously high energy consumption. the

The gas supply rate of each tubular membrane module (P4) is 0-20Nm3/h; the gas stripping pressure is preferably <0.05MPa. the
管式膜组件(P4)工作状态: Working status of tubular membrane module (P4):
1、过滤: 1. Filtering:
在过滤时,给水泵(2)将生化反应器(1)中的混合液送入管式膜组件(P4),给水泵(P2)用于保持恒定的进水流量,经循环泵(P3)提高流速从管式膜组件(P4)底部流向顶部;压缩空气经过空气压缩机(P6)压缩后经底部的布气器(P5)将空气均匀送入管式膜组件(P4)的腔体中。由于空气的上升驱动,带动混合液和悬浮固体上升,在膜管(10)表面保持一定的流速(1-3m/s),空气搅动擦洗膜表面,带走容易造成膜污染和堵塞的悬浮颗粒和胶体,混合液以错流形式流动,大于膜孔的颗粒和溶质被截留在膜表面,而小于膜孔的透过膜壁而使得水得到净化,实现固液分离。净化后的产水经产水出口(4), 气动阀门(V8)进入清水池。由于是错流过滤,浓水经气动阀门(V6)回到生化反应器(P1),使得生化反应器(P1)中污泥浓度不断增加,有利于进一步将难分解的有机物降解,从而提高生化效果;空气经排空管路排空。 During filtration, the feed water pump (2) sends the mixed liquid in the biochemical reactor (1) into the tubular membrane module (P4), and the feed water pump (P2) is used to maintain a constant feed water flow rate, which is passed through the circulation pump (P3) Increase the flow rate from the bottom of the tubular membrane module (P4) to the top; the compressed air is compressed by the air compressor (P6) and sent to the cavity of the tubular membrane module (P4) evenly through the air distributor (P5) at the bottom . Driven by the rise of the air, the mixed liquid and suspended solids rise to maintain a certain flow rate (1-3m/s) on the surface of the membrane tube (10), and the air stirs and scrubs the surface of the membrane, taking away the suspended particles that are likely to cause membrane fouling and clogging And colloid, the mixed liquid flows in the form of cross flow, the particles and solutes larger than the membrane pores are trapped on the surface of the membrane, and the particles smaller than the membrane pores pass through the membrane wall to purify the water and realize the solid-liquid separation. The purified product water enters the clear water pool through the product water outlet (4) and the pneumatic valve (V8). Due to the cross-flow filtration, the concentrated water returns to the biochemical reactor (P1) through the pneumatic valve (V6), so that the sludge concentration in the biochemical reactor (P1) increases continuously, which is beneficial to further degrade the refractory organic matter, thereby improving the biochemical Effect; the air is evacuated through the evacuation line. the
2、反洗: 2. Backwashing:
在设备运行过程中,污泥聚积在管式膜组件(P4)的内腔、膜管(10)的表面和膜孔内,为保持系统的正常运行。这些污染物必须定期通过反冲洗排出。 During the operation of the equipment, sludge accumulates in the inner cavity of the tubular membrane module (P4), the surface of the membrane tube (10) and in the membrane holes, in order to maintain the normal operation of the system. These contaminants must be removed periodically by backwashing. the
反洗过程中,开启空气压缩机(P6),无油压缩空气经气动阀门(V4),产水出口(4)从膜过滤的反方向进入管式膜组件(P4)的腔内,其反冲压力0.5MPa,连续脉冲式反冲洗2-3次,每次时间是2-3秒。气反冲后,再开启反洗泵(P7)用清水池中的产水反洗1-2min,过程是:反洗泵(P7)从清水池抽水从产水出口(4)进入管式膜组件(P4)的腔内,从进水口(1)流出,经反洗排污管回到生化反应器(P1)。在正常气反冲、水反洗15-20个周期后,需进行加强反洗,即在水反洗中,通过计量泵(8)投加化学药剂对管式膜组件(P4)进行10-15min的浸泡和清洗。一般在30-45天期间,还需对管式膜组件(P4)进行彻底的化学清洗,以恢复管式膜组件(P4)的原始通量。 During the backwashing process, the air compressor (P6) is turned on, the oil-free compressed air passes through the pneumatic valve (V4), and the product water outlet (4) enters the cavity of the tubular membrane module (P4) from the opposite direction of the membrane filtration, and the opposite direction The punching force is 0.5MPa, and the continuous pulse backwashing is 2-3 times, each time is 2-3 seconds. After gas recoil, turn on the backwash pump (P7) to backwash with the product water in the clear water tank for 1-2min. The process is: the backwash pump (P7) pumps water from the clear water tank and enters the tubular membrane from the product water outlet (4) The cavity of the component (P4) flows out from the water inlet (1), and returns to the biochemical reactor (P1) through the backwash sewage pipe. After 15-20 cycles of normal air backwashing and water backwashing, enhanced backwashing is required, that is, in water backwashing, the tubular membrane module (P4) is subjected to 10- 15min of soaking and washing. Generally, during 30-45 days, the tubular membrane module (P4) needs to be thoroughly chemically cleaned to restore the original flux of the tubular membrane module (P4). the
