Abstract
The utility model discloses a kind of fast cultivation system of aerobic granular sludge, comprise the travelling belt of belt filter press, drying installation, sludge pelletizer, granular sludge reactor and connection each several part.This system is cultivated by ordinary activated sludge being become closely knit putting in aerobic granular sludge reactor afterwards, not only shortens the incubation time of aerobic particle mud, also assures that the good removal effect of aerobic particle mud culturing process Middle nutrition material.The utility model preparation technology is simple, with low cost, can be applied to Practical Project on a large scale.
Description
Technical field
The invention belongs to environment protection, sewage treatment area, be specifically related to a kind of fast cultivation system of aerobic granular sludge.
Background technology
Aerobic particle mud is microorganism spontaneous cohesion in certain circumstances, propagation and the close structure formed, biological particles that good, the biological interoperability of settling property is strong.Due to its complex structure, there is multiple oxygen environment and nutrient environment in same particle, for various microorganism provides good growing environment, have multiple metabolic activity, thus aerobic particle mud has numerous advantage compared with traditional active sludge simultaneously.Many investigators have carried out the research of multiple high concentrated organic wastewater, metallic wastewater, toxic substances waste water and sanitary sewage in laboratory scale aerobic granular sludge reactor.Aerobic particle mud is considered to one of wastewater processing technology with broad prospect of application, receives increasing concern at present.
Aerobic granular sludge reactor adopts cotton-shaped active sludge to be seed sludge, its formation time generally needs more than 40-60 days, longer start time brings problems to the practical application of Aerobic Granular Sludge Technology, as the increase of running cost, in start-up course effluent quality often cannot be up to standard etc. problem; With part aerobic particle mud and the cotton-shaped active sludge of part for seed sludge accelerates aerobic granular process, own formation time of aerobic particle mud of its inoculation is longer, does not fundamentally solve the problem of floc sludge quick particle.Therefore, how to accelerate the granulating of floc sludge, the large-scale application realizing Aerobic Granular Sludge Technology becomes the problem of industry concern.
Summary of the invention
For the problems referred to above, the utility model provides a kind of fast cultivation system of aerobic granular sludge, to solve the long problem of aerobic particle mud incubation time.
The utility model discloses a kind of fast cultivation system of aerobic granular sludge, its technical scheme is as follows: a kind of fast cultivation system of aerobic granular sludge, and this system comprises the travelling belt of belt filter press, drying installation, sludge pelletizer, granular sludge reactor and connection each several part.Drying installation is made up of fan and travelling belt, and sludge pelletizer is the steel knife screen cloth of up and down certain pore size and the travelling belt composition of two alternations, and the thickness of steel knife screen cloth is 0-5mm, and the pore size of steel knife screen cloth is 0-5mm.Mud granule after the granulation of steel knife screen cloth transports to aerobic granular sludge reactor by the transport of travelling belt.Active sludge becomes mud cake through belt filter press, and sludge cake lentamente through drying zone, is blown away portion of water by fan and to become water ratio lower through travelling belt.Granulation zone is arrived after drying zone, sludge cake enters next travelling belt, second travelling belt carries out steel knife screen cloth cutting granulation, and the mud granule made is transported in aerobic granular sludge reactor through the 3rd travelling belt and cultivates, and whole process is orderly continuously.
The beneficial effects of the utility model are: a kind of fast cultivation system of aerobic granular sludge that the utility model provides, and by the mode of artificial granulation, form initial sludge accumulation body, substantially reduce the formation time of aerobic particle mud; And the mud granule rendered in aerobic granular sludge reactor initially has good imporosity and settling property, so mud not easily runs off in the start-up course of aerobic particle mud system, be beneficial to the removal of culturing process Middle nutrition material and the impact of resistance to unfavorable factor.

Embodiment
By describing technology contents of the present utility model, structural attitude in detail, reached object and effect, accompanying drawing is coordinated to be described in detail below in conjunction with embodiment 1.Should be understood that described in following examples it is for illustration of the utility model, instead of limit range of application of the present utility model, all equivalent transformations of doing according to spirit of the present invention or modification, all should be encompassed within protection scope of the present invention.The implementation condition adopted in embodiment can do further adjustment as the case may be, and not marked implementation condition is generally the condition in normal experiment.
Embodiment 1: a kind of fast cultivation system of aerobic granular sludge as shown in Figure 1.Ordinary activated sludge enters belt filter press 1 and carries out press filtration, and sludge cake out drops on above travelling belt 2 from belt filter press cake outlet, and travelling belt 2 has fan assembly 3 above, under the effect of fan, mud cake is continued dehydration.Travelling belt 2 is long, and it is consistent that transmission speed and pressure filter mud cake go out motor speed, ensures that individual layer mud cake transmits in face on conveyor belt 2.Sludge cake through drying zone drops on transmission above transmission belt 4 by travelling belt 2, just transmission is stopped immediately after a travelling belt 4 has fallen to expiring sludge cake above, then move to steel knife screen cloth 5 and carry out cutting granulation just below, steel knife screen cloth 5 moves up and down and carries out sludge cake cutting.Another travelling belt 4 immediately fills to continue to transmit the sludge cake that travelling belt 2 falls.Two travelling belts 4 hocket and transmit and the process of cutting.After cutting, steel knife screen cloth 5 lifts, and travelling belt 4 starts transmission, and mud granule is sent to above travelling belt 6, and travelling belt 6 is sent to granule sludge inside aerobic granular sludge reactor 7.The granulation transmitting procedure of such ordinary activated sludge just continuous like this carrying out in order, stops until reaching required sludge quantity in reactor 7.Ordinary activated sludge enters the cultivation carrying out aerobic particle mud in reactor again after closely knit granulation, substantially reduces the incubation time of aerobic particle mud.
