Description
Technical field
The present invention relates to sewage treatment fields, and in particular to a kind of anti-clogging water outlet sieve and moving bed biological film reaction
Device.
Background technique
Moving bed biofilm reactor (Moving Bed Biofilm Reactor, abbreviation MBBR) is mainly used in municipal administration
And Industrial Waste Water Treatments, principle are to make in carrier outgrowth not by adding a certain number of suspending carriers into reactor
Same microbe species make each carrier become miniature biological processor, and then improve treatment effect.
It since carrier is in suspended state, is flowed with water flow, it is therefore necessary to sieve be set by carrier and retain guarantee subsequent technique
Stable operation.But there are a large amount of organic matter and nitrogen and phosphorus elements in sewage, the attached microbial easily on sieve, are formed
Biomembrane blocks sewage flow direction.Therefore reasonable material is selected, the sieve of rational structure can operate normally MBBR technique has
Significance.Reasonable sieve is designed in addition to guaranteeing that enough intensity also needs to ensure reasonable water discharge speed.Water discharge speed is too
Carrier can be gathered on sieve by height with water flow migration, be resulted in blockage.Water discharge speed is too low and is not able to satisfy water process demand.
Summary of the invention
In order to solve the above-mentioned technical problem, an object of the present invention is to provide a kind of anti-clogging water outlet sieve, the sieve
Weft reinforcing rib and warp reinforcing rib is trapezoidal or triangle, and the top on the top of weft reinforcing rib and warp reinforcing rib
Be fixedly connected, can effectively prevent suspended particle clogging in gap, have be unlikely to deform, not easy to wear, surface is not easy aufwuch
Film, the features such as being readily cleaned.
The second object of the present invention is to provide a kind of moving-bed biofilm built-up by above-mentioned anti-clogging water outlet sieve
Reactor, water outlet screening level are arranged, and are all made of inside sieve and below perforated pipe ventilation aeration, the perforated pipe inside sieve
Filler can be effectively prevent to be deposited in above sieve, water outlet screen bottom is supported by support frame.
The present invention solves above-mentioned technical problem by the following technical programs.
In a first aspect, the present invention provides a kind of anti-clogging water outlet sieve, the sieve is cylindrical structure, including rounded
Weft reinforcing rib and linear warp reinforcing rib, the vertical stationary distribution of the two, the cross section of the two is isosceles trapezoid or waits
Lumbar triangle shape, and the top of weft reinforcing rib is fixedly connected with the top of warp reinforcing rib, reinforces weft reinforcing rib and warp
The bottom end of muscle is respectively positioned on the outside of respective top.
In the above-mentioned technical solutions, " top " in isosceles trapezoid refers to that end where its upper bottom edge, end where bottom are known as
" bottom end ", " top " in isosceles triangle refer to end where its apex angle, and end is known as " bottom end ", weft reinforcing rib and warp where bottom edge
The top of line reinforcing rib inwardly, bottom end outwardly, to make the seam on sieve inner surface or outer surface between adjacent two bottom end
Gap is respectively less than the gap between its internal adjacent two top, and sundries is effectively prevent to enter blocking gap, meanwhile, it is generated inside gap
Biomembrane can be outwardly or inwardly discharged in air purge.
Based on the above technical solution, further, the bottom end of weft reinforcing rib and warp reinforcing rib is in circular arc
With side (namely waist edge) rounding off, sieve pair can be effectively reduced in the top of shape, weft reinforcing rib and warp reinforcing rib
The influence of water velocity, while keeping sieve more aesthetically pleasing.
