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 grain sludge iris type classified collection device.
Background technology
Biologic treating technique is the mainstream technology of field of waste water treatment.Wherein, Anaerobic Microbiological Treatment Technology is low because of working cost, and the processing power height can reclaim advantages such as energy substance, has wide industrial applications prospect.Yet the cell yield of anaerobion is relatively low, and the biomass deficiency has become the main bottleneck of anaerobic technique industrial applications.Simultaneously, in the actual motion of efficient anaerobic technology, because reactor configuration limits, when too high or water impact is excessive when sludge concentration in the reactor, often there is the anaerobic grain sludge leakage.Therefore, the anaerobic grain sludge of necessary collection loss.
In addition, particle diameter is the important physical parameter of anaerobic grain sludge.For specific operating mode, there is more excellent grain diameter scope.When particle diameter was too small, granule sludge was difficult for holding in reactor and stays; When particle diameter is excessive, because causing biological activity, mass transfer limit reduces, and the two all can limit the performance of anaerobic reactor scrubbing potentiality.Therefore, also necessaryly when being collected, anaerobic grain sludge classifies according to size.
Summary of the invention
For solving the difficult problem of collecting of present anaerobic biological reactor loss granule sludge, the present invention proposes a kind of anaerobic grain sludge iris type classified collection device, the efficient collection of anaerobic grain sludge and effectively classification simultaneously can realize running off.
A kind of anaerobic grain sludge iris type classified collection device of the present invention, it is characterized in that: comprise the device body that has inner chamber, described device body one side top arranges water-in, a relative side top 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 setting form the granule sludge recovery zone; Each described granule sludge recovery zone is equipped with view port and has the mud discharging mouth of mud valve.
Further, described device body is rectangular parallelepiped, the length of 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 are according to granule sludge particle diameter screening degree, and the horizontal flow velocity during simultaneously in conjunction with anaerobic reactor water outlet access to plant body is adjusted.
Further, bottom, described granule sludge recovery zone is rectangular pyramid shape, and level inclination α is 45-60 °.
Further, described view port is made by 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: be communicated with the water-in of anaerobic reactor rising pipe and collection device, make the inner chamber of reactor water outlet access to plant body, open reflux pump then, carry out the mud collection process of long period; Confirm mud height by view port, fill up in case find the granule sludge recovery zone of device body, can close water-in and reflux pump, open corresponding mud valve and carry out spoil disposal classification recovery; Spoil disposal is closed mud valve after finishing, and continues to repeat aforesaid operations.
The invention has the beneficial effects as follows: 1. collect according to particle size classification the efficient recovery granule sludge time; 2. keep anaerobic environment, the anerobe activity is kept to greatest extent; 3. can adjust quantity of reflux according to operating mode and granule sludge characteristic, control flow velocity flexibly, improve and collect and classifying quality.
