A water inlet with an inlet valve is arranged at the upper end of the device body, a water outlet with an outlet valve is arranged at the bottom of the device body, the water inlet is communicated with an outlet pipe of an anaerobic reactor, the inner part of the device body is divided into a plurality of granular sludge recovery unit areas from the top down; each granular sludge recovery unit area is provided with a mud discharge port with a mud valve, and mesh screens are arranged between two adjacent granular sludge recovery unit areas. The device for screening and collecting anaerobic granular sludge disclosed by the utility model can screen grains while effectively recovers granular sludge, has simple structure of the whole device, convenient operation and low energy consumption, can be used for collecting the lost anaerobic granular sludge for a long term, and has high practical value.
Description
Technical field
The utility model relates to a kind of anaerobic grain sludge screening collection device, belongs to the high concentrated organic wastewater process field.
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 processing power is high, produces the advantages such as substance, has caused the common concern of Chinese scholars, becomes an important trend of following wastewater processing technology development.Yet under the anaerobic condition, the cell yield of anerobe is lower, and surplus sludge volume is few, its heavy industrialization is used hindered.Generally speaking, the anaerobic grain sludge that forms in the high efficiency anaerobic reactor (as: up flow anaerobic sludge blanket reactor, CGSB, inner circulation reactor etc.) has good settling property, is the source of the function of high-load anaerobic treatment process.But in actual moving process, because the restriction of self configuration when especially too high when sludge concentration in the reactor or water impact is excessive, the phenomenon of anaerobic grain sludge loss often occurs.For keeping anaerobic grain sludge concentration in the reactor, keep its higher contaminant removal capacity, make it effectively carry out biological wastewater treatment, the collection utilization of loss anaerobic grain sludge is particularly necessary.
In addition, grain diameter is one of most critical 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 easily ran off; When particle diameter was excessive, particle caused activity decreased because of mass transfer limit, all can limit the performance of anaerobic grain sludge pollutant removal potentiality.Therefore, also be necessary the anaerobic grain sludge of collecting is sieved processing.
Summary of the invention
The utility model has proposed a kind of energy efficient recovery anaerobic reactor loss granule sludge for the problem that granule sludge in the anaerobic granular sludge reactor runs off, and it is sieved anaerobic grain sludge screening collection device of processing.
The technical solution adopted in the utility model is:
Anaerobic grain sludge screening collection device, it is characterized in that: comprise device body, described device body upper end is provided with the water-in of water intaking valve, the water outlet that the bottom is provided with outlet valve, described water-in is communicated with the rising pipe of anaerobic reactor, described device body inside is separated into several granule sludge recovery unit districts from top to bottom, described each granule sludge recovery unit district all is provided with the mud discharging mouth of mud valve, between two adjacent described granule sludge recovery unit districts sieve is installed.
Further, the top of described device body is right cylinder, and the bottom convergent is cone; Described cylindrical aspect ratio is 4 ~ 5:1; The level inclination α of described cone is 55 ~ 60 degree.
Further, the upper surface of the minimum level position of described mud discharging mouth internal diameter and corresponding sieve in the same horizontal line.
Further, described sieve is circular, and the radius of sieve is identical with the internal diameter of device body; Described sieve number and the several certificates of order are adjusted the degree of the screening of granule sludge; The order number of described sieve increases from top to bottom gradually.
During use, first anaerobic reactor rising pipe and device body water-in are communicated with, open water intaking valve and outlet valve, begin to sieve collection process; The granule sludge recovery unit district that treats the device body is filled up, and closes water intaking valve and outlet valve, opens corresponding mud valve, granule sludge recovery unit district is carried out spoil disposal from top to bottom one by one reclaim; After finishing, continues spoil disposal to repeat aforesaid operations; After operation for some time, can utilize the anaerobic reactor water outlet to carry out back flushing by regulation and control water intaking valve, outlet valve and mud valve, avoid clogging of screen.
The beneficial effects of the utility model are: 1. can realize granule sieving when the efficient recovery granule sludge, for the granule sludge of different-grain diameter, take corresponding treatment measures, be conducive to high efficiente callback and the utilization of granule sludge; 2. whole apparatus structure is simple, and is easy to operate, and energy consumption is low, can be used in the long-term collection of loss anaerobic grain sludge, has higher practical value.
