Abstract
The invention discloses a mixed-flow type composite filling material. The composite filling material comprises a central cord; a plurality of sets of elastic blades are arranged around the central cord (1); each set of elastic blades independently spirals around the central cord and is composed of a plurality of elastic sub-blades (2), and each elastic sub-blade (2) is uniformly inserted into the central cord (1). According to the invention, through improvement of the original structure of an elastic filling material, the filling material is allowed to have a great specific surface area; in use of the filling material, a mixed flow revolving along the surface of the filling material is generated when a current passes through a filling material zone along any direction, so contact time of sewage and a biomembrane on the surface of the filling material is prolonged, and thorough degradation of pollution factors is realized; meanwhile, flowing of the mixed flow along the surface of the filling material can effectively wash away aged and easily detached biomembranes, is beneficial for self-renewal of microbes on the surface of the filling material and maintenance of activity, prevents caking caused by over-thick aged biomembranes produced by the filling material and enables the specific surface area of the filling material to be effectively maintained and the service life of the filling material to be prolonged.
Description
Technical field
The invention belongs to field of Environment Protection, be specifically related to a kind of Novel biofilm carrier, this filler is mainly used in wastewater treatment, and especially the high loading of high-concentration salt-containing wastewater is processed.
Background technology
At present, all need to use various bio-carriers in the Biological Contact Oxidation Process that at home and abroad extensively adopts in Sewage Treatment Project and biological filtering tank process, bio-carrier is of a great variety, and relative merits are respectively arranged, existing movable type, also have fixed.
Existing fixed filler great majority all exist work-ing life short, easily stop up, and easily cause specific surface area to descend and the problem of having to change, and microbial film and sewage are short duration of contact, can not fully react, inefficiency.But, change filler and not only can cause the increase of Sewage Plant operation cost, and due to the needs construction reformation, also need biofilm again after transformation is completed, will affect the continuous operation of Sewage Plant, cause processing power to descend, as accident, there is the risk that causes environmental hazard.
Summary of the invention
The object of the invention is to overcome the deficiency that above technology exists, provide a kind of special spirane structure that has, the long lifetime that can utilize nature waterpower flow system to make mixed flow, high-level efficiency mixed-flow composite elastic filler.
The objective of the invention is to realize in the following manner:
A kind of mixed-flow compounded mix, this compounded mix comprises umbilical cord, around umbilical cord, many group spring leafs is set, and every group of spring leaf rises around the axial cord independent spiral, each is organized spring leaf and is made of multi-disc elasticity blades, and each elasticity blades evenly inserts in umbilical cord.Every elasticity blades is preferably petal-shaped.
The spring leaf group number that rises around the axial cord independent spiral is the 2-20 group, and the elasticity blades is wide is 3mm-500mm.
Described umbilical cord can be the nylon umbilical cord, and the elasticity blades can or both combine for nylon fiber elasticity blades or high density polyethylene(HDPE) elasticity blades.
Beneficial effect of the present invention compared with the prior art: the present invention is mainly by improving the original structure of elastic filler, blade screw rising form makes filler have great specific surface area, during use, current pass through the packing area from any direction, all will produce along the mixed flow of filling surface rotation, thereby extend sewage and filling surface biomembranous duration of contact, realize the thorough degraded of pollution factor.Simultaneously, mixed flow flows through along filling surface, will effectively wash away aging caducous microbial film, the self that is conducive to the filling surface microorganism keeps active, prevents that filler from producing the problems such as bonding that blocked up aging microbial film causes, can effectively keep its specific surface area, increase the service life.
Elasticity blades of the present invention can adopt different materials, in order to adhere to different types of microorganism, has good comprehensive Degradation for the various waste water of composition.For the high-concentration waste water of single component, can also adopt pointed material, adhere to specific microorganism, reach and improve load, the purpose of high-level efficiency degraded.

Embodiment
Above-mentioned explanation is in order to help better further to understand invention, but the embodiment detail is only for invention is described, but do not represent under inventive concept all technical schemes.
As shown in Figure 1, a kind of mixed-flow compounded mix, this compounded mix comprises umbilical cord, around umbilical cord 1, many group spring leafs are set, every group of blade rises around umbilical cord 1 independent spiral, each is organized spring leaf and is made of multi-disc elasticity blades 2, and each elasticity blades 2 evenly is inserted in umbilical cord 1.Every elasticity blades 2 is petal-shaped.Spring leaf group number is the 2-20 group, the wide 3mm-500mm of elasticity blades 2.Umbilical cord 1 is the nylon umbilical cord, and elasticity blades 2 is nylon fiber elasticity blades or high density polyethylene(HDPE) elasticity blades or both combines.
When the present invention installs and uses, the materials such as employing steel pipe are made the two-layer fixedly filler support 3 in up and down, the useful length of mixed-flow compounded mix of the present invention is the distance between two-layer fixedly filler support 3, and the two ends of every filler are tied up to respectively up and down fixedly on filler support 3.
Current pass through the packing area from any direction, all will produce the mixed flow along filling surface rotation, thereby extend sewage and filling surface biomembranous duration of contact, realize the thorough degraded of pollution factor, simultaneously, mixed flow flows through along filling surface, will effectively wash away aging caducous microbial film, is conducive to the self of filling surface microorganism, keep active, prevent that filler from producing the problems such as bonding that blocked up aging microbial film causes, can effectively keep its specific surface area, increase the service life.
