Description

Spherical multiple rotating biological carrier

The utility model belongs to sewage microbial method processing technology field.It relates to the biology that a kind of sphere rotates again and carries this.

Before the seventies, biologic packing material has two kinds of fixed and flow models.The fixed filler has: hard filler (honeycomb padding), soft-filler, semi soft packing, flexible stereo filler, biological adaptive color elastic solid filler, elasticity combined stuffing, peltate filler etc.This fixed filler installation cost height, maintenance difficult, the microorganism on the filler contacts weak effect with nutrition, and biochemical efficiency is low.The flow model filler has: powder activated carbon, powder coke, plastic foam, quartz sand etc.Use this class filler to exist and reclaim difficulty, power consumption is big, shortcomings such as sludge blockage.

Closely during the last ten years, occur a kind of novel floated biologic packing material in the water technology, it suspends in water, and has overcome the shortcoming of fixed filler and flow model filler.But existing floated biologic packing material still exists, and easy obstruction, biofilm are poor, not high, the biochemical weak effect of oxygen transfer rate, the high deficiency of cost of manufacture.

Based on the problem that prior art exists, task of the present utility model provides a kind ofly all has affine magnetism to different pollutents, and specific surface area is big, and easy to be filmed does not stop up, and biochemical function is strong, bio-carrier with low cost.

The utility model is a spherical multiple rotating biological carrier, and this bio-carrier is moulded silk (3), a hollow rotating shaft (4), permanent sleeve (5) by the sphere in the netted outer cover of sphere (1) endosphere (2) insertion endosphere table hole and supported cone parts such as (6) and form.See accompanying drawing 1, its characteristics are:

1. this support shapes is spherical, and in current water, this carrier can whole be done the rotation of any direction; Its endosphere and be positioned endosphere lip-deep radial mould the silk also rotatable, can produce the repetition shearing action to current water and water oxygen gas, so dissolved oxygen in the water body (DO) is increased, help satisfying the demand of aerobic microbiological to oxygen, promote the oxygenolysis of microorganism to organic pollutant in the sewage, and help aging biomembranous coming off, prevent that carrier from reducing its biochemical efficiency because of aging microbial film stops up.

2. the spherical netted outer cover of this carrier, the radial sphere that particularly is positioned the endosphere surface is moulded silk, the specific surface area of whole carrier is increased, like this, increased microorganism implantation fixed-area on the one hand, also increased simultaneously the contact area of nutrition, organic pollutant in biological and the water body, more helped microorganism to the absorption of nutrition with to the aerobic decomposition of organic pollutant.

3. after this carrier radial sphere of being positioned endosphere was moulded silk operation for some time biofilm, its skin was an aerobic zone, and the middle level is an aerobic area, and the close centre of sphere partly is an anaerobic zone.Therefore, after this carrier biofilm, that each carrier monomer has all been built up is aerobic, the dissimilar microbial populations such as oxygen, anaerobism of holding concurrently.Each carrier all has simultaneously aerobic (oxygen of holding concurrently) decomposes, the ability of anaerobic digestion.Therefore use its biochemical efficiency of this carrier to improve greatly, and can realize not having the perfect condition of excess sludge.

4. this carrier is in the course of processing, can be according to dissimilar water quality, the polarity or the nonpolar auxiliary material that in the basic raw material polypropylene, add different components and different ratios, can form affine, adsorption to different organic pollutants in the different water bodys, thereby improve the efficient degradation of microorganism different pollutents.Therefore, this carrier is applicable to dissimilar wastewater treatments such as petrochemical industry, printing and dyeing, agricultural chemicals, chemical industry, medicine, food, process hides, papermaking, lives.

5. this carrier is anticorrosive, high temperature resistant, anti-aging, intensity is high, shock resistance, long service life.
