Embodiment Construction

[0016] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0017] Such as figure 1 and figure 2 Shown: a high-efficiency denitrification biological carrier filler and its application in sewage treatment, its process and application are as follows:

[0018] (1) The bamboo is woven into hollow bamboo balls with round holes at both ends through 7 processes of sawing, rolling, cutting, scraping, splitting, shredding and weaving. The bamboo slices are 0.4 cm wide, and the bamboo slices are approximately equal in width, and are woven with round holes to form two symmetrical round holes, the diameter of which is 1 cm. There is a certain distance between bamboo and bamboo, and the distance is 0.2-0.5cm. The size of the hollow bamboo ball is: 4cm in diameter.

[0019] (2) Put the polyethylene raw material i...

Abstract

The invention discloses an efficient denitrification biological carrier filler and applications of the efficient denitrification biological carrier filler in sewage treatment. The efficient denitrification biological carrier filler comprises a shell and hollow bamboo balls, and specially comprises a hollow plastic spherical shell and a plurality of built-in hollow bamboo ball knitted from phyllostachys pubescens strips, wherein the surface of the phyllostachys pubescens contains a large amount of hydroxyl groups and carboxyl free radicals, and has good hydrophilicity and good bio-affinity so as to rapidly form the active sludge film and provide the firm active sludge film, and when the carbon source is insufficient, the hollow bamboo balls can be decomposed into denitrifying bacteria so as to provide the carbon source. According to the present invention, the efficient denitrification biological carrier filler has the characteristics of rapid film forming and firm formed film of the bamboo filler, the characteristic of high mechanical strength of the plastic filler, further has characteristics of greatly-increased filler surface area, unit volume biomass increasing, greatly-increased active sludge concentration in the reactor, nitrification effect improving, denitrification effect improving, and substantially-increased denitrogenation efficiency of the high concentration nitrogen-containing wastewater.

Description

technical field [0001] The invention relates to a sewage treatment material, in particular to a high-efficiency denitrification biological carrier filler and its application in sewage treatment. Background technique [0002] Biofillers provide a stable environment for microorganisms to inhabit and reproduce, and affect the growth, reproduction and shedding of microorganisms. The filler is the place where the biofilm in the reactor contacts with the wastewater, and it can have a mandatory turbulent effect on the water flow, so that the wastewater can be redistributed. The filler material, specific surface area, filler surface roughness, water distribution and gas distribution performance, strength, density and cost, etc., directly affect the efficiency of wastewater treatment and the feasibility of operation. Organic polymer filler is one of the most promising biofilm carriers at present. The common biological fillers on the market are mainly made of polypropylene, polyethyl...
