UASB/IC

厌氧反应—UASB和IC

DAACH 的厌氧反应工艺具有较高的有机物去除能力, 水力停留时间短, 能耗低等特点. 我们领先的膨胀颗粒污泥床（IC）已经证实其处理效果优于任何其他厌氧系统. 

DAACH 的厌氧反应技术可在最小的占地面积下同时具有最佳的总去除率. 

每一个系统的设计都是为了有效满足客户的排放要求

膨胀颗粒污泥床反应器（IC）.

IC 反应器是比 UASB 反应器更先进的厌氧反应器. 由于 IC 具有较高的水力上升速度, 从而传质效率高. 

较高的水力上升流速, 使得反应器的相对水力停留时间大大缩短, 从而大大缩小了反应器容积, 并且能

够去除大量的有机物.

DAACH 的 IC 厌氧反应器优点：

占地面积小反应器密闭设计无需 "每 6-9 个月进行一次清泥”的污泥处理"高沉降性能的颗粒污泥

运行成本更低

耐负荷变化

沼气副产物

升流式厌氧污泥床反应器（UASB）

升流式厌氧污泥床（UASB）是一种圆柱形生物反应器, 进水通过反应器底部流入, 穿过污泥区后在顶部的气/固/液分离区中进行分离, 分离区中的微生物聚集形成生物颗粒.

DAACH的 UASB的 优点：

污泥产量更低

低能耗占地面积较省

经济实用的高消化污泥在反应器中的停留时间达 90 天

沼气副产物

每一个系统的设计都是为了有效满足客户的排放要求. 

ANAEROBIC DIGESTION - UASB AND EGSB

CWT’s Anaerobic Digestion process offers high organic removal capacity with short hydraulic retentions time and low energy demand. Our state of the art Expanded Granular Sludge Blanket (EGSB) has proven results that it works better than any other anaerobic system. 

CWT's Anaerobic Digestion incorporates theBEST OVERALL REMOVAL RATES with the SMALLEST POSSIBLE FOOTPRINT. 

EACH SYSTEM IS DESIGNED TO EFFECTIVELY HANDLE CUSTOMER'S EFFLUENT REQUIREMENTS

EXPANDABLE GRANULAR SLUDGE BED REACTOR (EGSB).

The EGSB reactor is a sophisticated modification of the UASB technology which operates at high up flow velocities and promotes a better mass transfer. It can remove the greatest amounts of organic material in a smaller volume.

CWT’s EGSB Advantages:

• Small Footprint

• Sealed Reactor Design

• No Sludge Handling "Removal of sludge every 6 – 9 months"

• Highly settleable granular biomass

• Economical operation

• Resistance to changes in loads

• Methane gas byproduct 

UPFLOW ANAEROBIC SLUDGE BLANKET REACTOR (UASB)

The Upflow Anaerobic Sludge Blanket (UASB) is a cylindrical bioreactor where influent is fed through the bottom of the reactor, crosses up through the sludge zone and is separated in the Gas/Solid/Liquid (GSL) at the top where Microorganisms are grouped together as biogranules.

CWT’s UASB Advantages:

• Lower Sludge Generation

• Low Energy Requirement

• Relatively Small Footprint

• Economical Operational Highly Digested Solids can remain in the reactor for up to 90 days

• Methane gas byproduct

Each System is designed to effectively handle the customer's effluent requirements.
