Description

A kind of bacterium delivery device
Technical field
The present invention relates to water pollution processing technology field, more particularly to a kind of bacterium delivery device.
Background technology
Because water resource protection for a long time is not affected by enough attention, drinking water source is generally contaminated, in drinking water The micro quantity organic pollutant toxic to human body of huge number is found that, such as carcinogenic, teratogenesis, mutagenic matter and chlorination disappear Toxic byproduct.Ozone-seed activity carbon treatment process is have developed in this context, is served and is preferably ensured drinking water water The effect of matter.With the development of water quality inspection technique, many new quality problems are found that again, such as giardia lamblia and Cryptosporidium (two worms) problem, water flea, red worm problem, the Biostatic sex chromosome mosaicism of water, high ammonia-nitrogen content problem etc..Therefore, including China Tightened up water sanitary standard is all worked out to drinking water in countries in the world inside.Ozone-seed activity carbon treatment process pair In above-mentioned quality problem, it is impossible to obtain gratifying treatment effect.Such as all can not 100% to " two worms ", water flea, algae Ground removes, to high ammonia-nitrogen content, 2~3mg/l of ammonia-nitrogen content ＞, it is difficult to drop to requirement of water standard etc..In addition, ozone oxygen Change can generate bromate, formaldehyde etc. and have the oxidized byproduct of more serious toxic action to human body, make ozone widely use by Query；Also research is pointed out, bacterial content significantly increases in the water outlet of granular activated carbon, bacterium chlorine resistance strengthens, and is flowed out with water Trickle carbon granule can have a negative impact to follow-up Disinfection Effect.In this context, lived up for developing than ozone-particle Property the safer more effectively drinking water advanced treatment technique of charcoal.
At present, had been a great concern in drinking water treatment field, hyperfiltration technique.Ultrafiltration can effectively go water removal in Grain thing, makes delivery turbidity be reduced to below 0.1NTU, and can remove macromolecular organic pollution, almost 100% worm of retention two, Water flea, red worm, algae, the bacterium even microorganism such as virus.But independent ultrafiltration is to the removal ability of dissolved organic matter in water Very limited, especially small-molecular-weight, easily biological-degradable organic matter, ultrafiltration can hardly remove.And this part small-molecular-weight has Machine thing can but cause the Biostatic sex chromosome mosaicism of water, cause bacterium Second propagation in pipe network, deteriorate water quality.Simultaneously ultrafiltration for Ammonia nitrogen can not also remove.
The content of the invention
In order to solve the above-mentioned technical problem, it is thin for being launched into water source the invention provides a kind of bacterium delivery device Bacterium, including：
Barrel-shaped support；
Buoyance module, its be arranged along the barrel-shaped support circumferentially around the barrel-shaped support, the buoyance module Material be selected to provide buoyancy with so that the barrel-shaped support is swum in the water source；
Bacteria culture media, its be arranged along the buoyance module circumferentially around the buoyance module, it is thin for providing Bacterium is to decompose the pollutant in the water source；With
Degradable housing, its be arranged along the bacteria culture media circumferentially around the bacteria culture media, for will The bacteria culture media is wrapped in the degradable housing.
Further, the bacteria culture media includes：
Culture medium cell body；With
Bacterium solution, it is placed into the culture medium cell body, and the bacterium is formed to prepare；
Wherein, the bacterium includes any one in aerobic nitrogen-fixing bacteria, Bacillus sphaericus, Lactobacillus plantarum and red spirillum Kind or several combinations.
Further, the weight percent score of the aerobic nitrogen-fixing bacteria, Bacillus sphaericus, Lactobacillus plantarum and red spirillum Wei not 10-20%, 10-20%, 20-30% and 20-25%.
Further, the material of the degradable housing is starch plasticses.
Further, the buoyance module includes：
Cryptomere buoyancy elements, one space of restriction in it；With

Further, the rubbery foam also includes the component based on following parts by weight：
Foaming agent, 11-15 parts；
Pore-creating agent, 1-5 parts；With
Expanded graphite 10-30 parts.
The solution of the present invention, due to barrel-shaped support and buoyance module so that bacterium can be floated in water source and It is launched during rolling.Outside bacteria culture media can be degradable housing due to being covered in so that bacterium is at water source Can gradually it be released during middle floating, with the degraded of housing so that bacterium is gradually released, thus to the pollution in water source Thing is gradually decomposed.Further, since activated carbon granule and diatomite particle can be placed in buoyance module so that utilizing Pollutant is adsorbed while bacterium is decomposed to pollutant.Again due to rubber can also be placed in the buoyance module Foam, and foaming structure surface area is larger, so as to have good adsorptivity to metal ions in sewage absorption.And barrel-shaped branch Frame can be rolled with wind, it is not necessary to be fixed on a fixed position so that the area that bacterium is launched greatly increases.
