Abstract
An anaerobic granular sludge partition-type separate collection device contains a device body with a core space. The top of one side of the device body is provided with a water inlet, and the top of the other side of the device body is provided with a water outlet and a reflux inlet. The reflux inlet communicates with the water inlet through a reflux pump. The core space of the device body is arranged by parallelly and vertically disposing baffle plates from left to right in order so as to form granular sludge recovery zones. Each of the granular sludge recovery zones is provided with a watch window and a sludge discharge port with a sludge discharge valve. The invention has the following beneficial effects: 1, the granular sludge is effectively recovered while separate collection is carried out according to the particle size; 2, the anaerobic environment is maintained so as to keep activity of anaerobic bacteria to the maximum; and 3, quantity of reflux can be adjusted according to the working condition and characteristics of the granular sludge, water velocity is flexibly controlled, and collection and separation effect is raised.
Description
Technical field
The present invention relates to a kind of Anaerobic granular sludge partition-type separate collection device.
Background technology
Biologic treating technique is the mainstream technology of field of waste water treatment.Wherein, Anaerobic Microbiological Treatment Technology because of working cost low, processing power is high, can reclaim the advantages such as energy substance, has wide industrial applications prospect.But the cell yield of anaerobion is relatively low, biomass deficiency has become the Main Bottleneck of anaerobic technique industrial applications.Meanwhile, in the actual motion of efficient anaerobic technique, because reactor configuration limit, when sludge concentration in reactor is too high or water impact is excessive, often there is anaerobic grain sludge leakage.Therefore, the necessary anaerobic grain sludge collecting loss.
In addition, particle diameter is the important physical parameter of anaerobic grain sludge.For specific operating mode, there is preferably particle size range.When particle diameter is too small, granule sludge is not easily held and is stayed in reactor; When particle diameter is excessive, because mass transfer limit causes biological activity to reduce, the two all can limit the performance of anaerobic reactor scrubbing potentiality.Therefore, also necessary anaerobic grain sludge is collected while classify according to size.
Summary of the invention
For solving the problem that current anaerobic biological reactor loss granule sludge difficulty is collected, the present invention proposes a kind of Anaerobic granular sludge partition-type separate collection device, Efficient Collection and the effectively classification of loss anaerobic grain sludge can be realized simultaneously.
A kind of Anaerobic granular sludge partition-type separate collection device of the present invention, it is characterized in that: comprise the device body with inner chamber, described top, device body side arranges water-in, top, relative side sets out the mouth of a river and refluxing opening, and described refluxing opening is communicated with described water-in through reflux pump; Described device body inner chamber by baffle plate from left to right successively parallel vertical arrange and form granule sludge recovery zone; Granule sludge recovery zone described in each is equipped with view port and the mud discharging mouth with mud valve.
Further, described device body is the length of rectangular parallelepiped, described device body: wide: be 4-6:1:3 at high proportion.
Further, described baffle plate is rectangle, and described barrier width equals described device body width, and described height of baffle plate equals the 1/2-2/3 of described device body height.
Further, described baffle spacing and quantity thereof sieve degree according to granularity, adjust in conjunction with horizontal flow velocity during anaerobic reactor water outlet access to plant body simultaneously.
Further, in rectangular pyramid shape bottom described granule sludge recovery zone, level inclination α is 45-60 °.
Further, described view port is made up of synthetic glass, is located at the 1/2-2/3 place of described device body height.
The operating process of this collection device is as follows: the water-in being communicated with anaerobic reactor rising pipe and collection device, makes the inner chamber of reactor water outlet access to plant body, then open reflux pump, carry out the mud collection process of long period; Confirm mud height by view port, once find that the granule sludge recovery zone of device body fills up, water-in and reflux pump can be closed, open corresponding mud valve and carry out spoil disposal classification recovery; Spoil disposal terminates rear closedown mud valve, continues to repeat aforesaid operations.
The invention has the beneficial effects as follows: 1. collect according to particle size classification while efficient recovery granule sludge; 2. maintain anaerobic environment, anerobe activity is kept to greatest extent; 3. according to operating mode and Characteristics of Granular Sludge adjustment quantity of reflux, flow velocity can be controlled flexibly, improves and collect and classifying quality.
