Abstract

The invention provides a multi-directional deflection filler for a sewage treatment process, which is mainly characterized in that the filler is formed by adhering filler plates (1) to each other; on the filler plates with deflection belts (2), the deflection belts (2) which are staggered and adjacent show T-shaped vertical distribution condition with angles of 45 DEG and 135 DEG; and clearances among the deflection belts (2) with the angles of 45 DEG and 135 DEG are water flow channels. Adhesion surfaces (4) of the deflection belts (2) are adhered with other filler plates to form a filler unit body, and clearances of the deflection belts between the filler plates form inclined water flow channels. The filler with the technology has different directions of water flow channels and conditions of multi-directional organism rejection, contact and digestion, thereby providing the filler applied to the treatment by a biofilm method for a sewage treatment process with a horizontal plug flow mode.

Description

Multidirectional baffling filler

Technical field:

The present invention relates to a kind of filler of sewage treatment process, belong to a kind of multidirectional baffling filler that can satisfy sewage disposal under complicated streamflow regime.

Technical background:

The present invention is applied to sewage treatment process, is specially adapted to the applying filler of the sewage disposal under advective model.Sewage water treatment method generally is divided into activated sludge process and biomembrance process, and biomembrance process is by increasing the form of filler in sewage treatment process, at filling surface formation microbial film, thereby realizing sewage disposal.With the anaerobic treatment is example, the technology of anaerobic treatment lays particular emphasis on the art breading of current up and down substantially, so, the filler of design also all is in order to satisfy the work under vertical direction processing condition up and down, since lack horizontal flow to the biomembrance process sewage treatment process, so lack filler under advective model.Filler commonly used now, the particulate inorganic filler as various pebble packings or other materials has gasket packing, the honeycomb fashion filler, the filler of suspension, suspension type filler or the like, but certain suitability is all arranged, and these applying filler are in the sewage disposal of crossing current state or complex state, and are unsatisfactory.Diversity exploitation along with the sewage treatment process pattern, novel process is arisen at the historic moment to the demand of the water treatment filler under the complicated fluidised form, in order to adapt to the needs of novel sewage treatment process, need a kind of sewage disposal filler that can satisfy complicated current characteristics of exploitation.

Summary of the invention:

The objective of the invention is to design a kind of water stream channel with different directions, bigger specific surface area can fully be held back organism, and is durable high-strength, is applicable to the filler of using under the complicated flow condition.

Technical scheme of the present invention is the filler plate that employing PVC material mechanical forming process produces monolithic, and the baffling band by projection between the multi-disc filler plate coheres mutually, forms the filler body, and the filler body is three-dimensional to be placed, and current can be from front and back different directions circulation up and down.The direction that the baffling band that distributes on the filler plate all is 45 ° and 135 ° distributes, 45 ° of baffling bands of each bar and adjacent 135 ° of baffling bands are " T " font each other and arrange, keep distance mutually as water stream channel between 45 ° and the 135 ° of baffling bands, the two ends of each 45 ° (135 °) baffling bands corresponding respectively the baffling band middle part of 135 ° (45 °), successive is staggered to have the "T"-shaped structure of spacing to form multidirectional water stream channel.In order to increase specific surface area and to adhere to roughness, can suppress different concave convex textures as required on the surface of filler plate, perhaps on the surface of filler plate, form the coarse effect of frosted with the form of mould molding or spraying; Baffling band on the filler plate can adopt the convex slot baffling band with the filler plate integral type, and the method that convex slot mould molding, special machinery are produced forms, and when the upper top of convex slot and another piece filler plate cohere, has just formed the filler body; It is the form of split that the baffling band also can be taked with filler plate, the spacing of the altitude mixture control filler plate by control baffling band, the baffling band of split is by the face that coheres at two ends, cohere with adjacent two filler plates respectively in corresponding position and to link to each other, the baffling band of split is taked the method processing of plastics machinery injection moulding, can adopt I-shaped monolithic traverse baffle according to the needs baffling band of specific surface area, also can be the parallel baffle groups of multi-disc.Three-dimensional arrangement of filler unit by filler plate forms forms the polymodal current channel pattern of front and back up and down.

The present invention is a kind of sewage disposal filler, is applicable to the sewage treatment process of different water (flow) directions.This filler is on working mechanism, require to design according to the basic function of sewage disposal to filler, in anaerobic treatment process, the primary condition that satisfies a good anaerobic treatment process of realization is, 1, abundant biomass to be arranged, have a large amount of specific surface areas in other words; 2, have good rejection to organics condition, the effect of mass transmitting of organism digestion is abundant.Multidirectional baffling filler requires design at these.In sewage treatment process, the surface of filler forms the large number of biological film, when sewage is flowed through filler in the horizontal direction, sewage is at first along 45 ° baffling band direction plug-flow, and with process in traverse baffle and the microbial film on filler plate surface fully contact digestion, be subjected to the influence of 135 ° of baffling bands of front forward in the process of plug-flow, water (flow) direction is turned back, beginning moves along 135 ° of direction plug-flows, the inner water stream channel condition that forms the different directions perforation of filler body.The multidirectional passage that the baffling band of "T"-shaped structure forms has produced sufficient contact, collision, rejection to organics and effect of mass transmitting to sewage, and current are carrying out the baffling operation repeatedly in the filler body, forms contact digestion condition fully.Owing to be provided with staggered baffling band, the specific surface area of filler is improved.In the sewage treatment process of advection, simultaneously also can produce gas, suspended substance and throw out because of digestion, the design of multidirectional baffling equally also provides the suspension passage that makes progress and downward precipitation passage, avoids inner and stops up.In addition under complete buried condition, under the effect of hydraulic pressure, current are except the moving of horizontal direction, also can there be flowing of sewage in vertical direction, in this case, the T-shape structure can show the condition of the sewage baffling digestion identical with horizontal direction, forms the sewage digestion condition that is suitable for different directions.The length of baffling band and density degree can be according to concentration of wastewater and need of work specific designs.

Beneficial effect of the present invention is reflected in by above technical measures and can makes the sewage disposal under the advection state adopt biomembrance process, the anaerobic treatment process of special advection has obtained to meet the filler condition of processing requirement, solved under the motorless advection condition, in anaerobic treatment, use the problem of filler, make filler obtain bigger specific surface area and rejection to organics digestion condition to different directions plug-flow contact digestion.
