Problems solved by technology

Packing bed clogging is a common problem in the engineering application of biotrickling filters, and the layer-by-layer filling method of traditional biotrickling filter greatly increases the workload and operation difficulty of backwashing, cleaning and replacement of packing
When the concentration of organic matter in the influent is high, the microorganisms in the packing bed will grow rapidly, and the packing bed will be blocked in a short time, requiring frequent backwashing, which will cause disadvantages to the operation of the sewage treatment process and restrict the use of the biological trickling filter in the treatment of high-concentration organic wastewater. application

Embodiment 1

[0023] A non-clogging biological trickling filter, its planar structure is as follows figure 1 As shown, the biological trickling filter is composed of a water inlet pipeline 1, a water distributor 2, a packing module 3, a filler module support frame 4 and a water outlet system 5. The water inlet pipeline 1 and the water distributor 2 are mainly used to evenly distribute the water To the function of the filler module 3, all the fillers can be in contact with the sewage. According to the amount of water inflow and the number of water distributors 2, a hole with a diameter of 6mm is opened on the water inlet pipeline 1, so that the inflow water is first distributed evenly through the pipeline holes to the The water distributor 2, and then rely on the overflow weir designed by the water distributor 2 for secondary distribution, and the influent water is evenly distributed to the packing module 3; the packing module 3 is made of PVC material, and its structure is as follows figur...

Embodiment 2

[0026] A non-clogging biological trickling filter. The biological trickling filter is composed of a water inlet pipeline, a water distributor, a filler module, a filler module support frame and a water outlet system. The water inlet pipeline and the water distributor are mainly used to evenly distribute the inlet water to The role of the filler module is to make all the fillers in contact with the sewage. According to the amount of water inflow and the number of water distributors, holes with a diameter of 15mm are opened on the water inlet pipeline, so that the inlet water is first evenly distributed to the water distributor through the holes in the pipeline, and then Relying on the overflow weir designed by the water distributor for secondary distribution, the influent water is evenly distributed to the packing module; the packing module is made of polyvinyl chloride material, in order to increase the path of water flowing through the packing module, the packing module is desi...

Abstract

The invention relates to a non-blocking biological tricking filter which consists of a water inlet pipeline (1), a water distribution device (2), a padding module (3), a padding module support frame (4) and a water discharge system (5), wherein the water inlet pipeline (1) and the water distribution device (2) are arranged at the upper part so as to uniformly distribute inflowing water into the padding module (3) which is arranged vertically, the padding module support frame (4) is used for supporting the plastic padding module (3), and the water discharge system (5) is arranged at the lowest part to collect, backflow and discharge treating water. Compared with the prior art, the invention greatly improves the effective contact area of a biological film on the surface of a padding layer with the waste water, enhances the mass transfer efficiency of pollutants from the waste water to the biological film, satisfies the contact requirement of the waste water and the microbiological film on the surface of the padding layer, ensures treatment effect, and simplifies structure and reduces investment by adopting a modularization production mode.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a non-clogging biological trickling filter. Background technique [0002] Biotrickling filter is a kind of biological filter, which is mainly used for sewage treatment. Traditional biological trickling filters generally adopt a relatively closed columnar structure, usually consisting of a pool body, water distributor, packing bed, and effluent collection. Traditional biological trickling filter fillers basically use materials such as gravel, ceramsite, charcoal, rags, fibers, etc., and are placed in the packing bed in a layer-by-layer manner. In order to prevent the particles mixed in the influent from clogging the packing bed, the influent must be pretreated. Only coarse screens are not enough, and fine screens less than 1mm or primary sedimentation tanks should be used. If the influent pretreatment is improper, or the concentration of organic matter in the influent is high, it is ...
