Description
Technical field
The invention belongs to biotechnologies, and in particular to a kind of biological agent for being used to handle heat and power*.plant wastewater.
Background technology
The electric power of China is the electrification structure based on fire coal, therefore flyash problem is very prominent.With regard to national average case
From the point of view of, the one ton of coal that often burns just generates 250~300 kg flyash.From now on, with the increase of coal-burning power plant's quantity, go out ash quantity also
It will increase.A large amount of flyash must be from steam power plant to ash disposal area, and it is ratio that ash and slag are sent to grey field using ash trench system
More economical method and a kind of current main ash disposal mode of China, after clinker water is sent to grey field with pipeline, in grey slurry
Coarse dispersion impurity precipitate in Hui Chang, the water after clarification can be directly discharged into water body or send back to power plant cycle use.Now
Flyash is deposited in grey field by most of power plant, just generates a large amount of ash flushing water thus.But ash flushing water water quality just has occurred very
Big change, such as pH, SS index have exceeded the discharge standard of national regulation, this makes water of the ash flushing water as coal-burning power plant's maximum
Pollution sources.It is environmental protection now, national regulation is not allowed lime-ash to be discharged into river, it is necessary to be comprehensively utilized or be sent to grey field
It stacks.And ash flushing water in alkalinity if do not administered, directly outer row not only polluted-water, and coal-burning power plant must also pay blowdown with
Exceeded expense.Therefore ash flushing water becomes a new problem of steam power plant's wastewater treatment.
Patented technology " a kind of biological agent for being used to handle cable duct ash flushing water " before applicant can be formed various
The strain of dominant microflora and algae are configured to high-performance bio preparation, and processing pollutant effect is good, and compatibility is reasonable, but exists and hang
Film rate is low to obtain defect, needs to regularly replace preparation, causes to waste.
Invention content
The defects of in order to overcome the prior art, the object of the present invention is to provide a kind of for handling the life of heat and power*.plant wastewater
Object preparation, said preparation include large aperture carrier and microbial inoculum, microorganism on carrier biofilm rate height, service life length, strong adhesive force,
Secondary pollution water body caused by thalline is lost in is avoided, saves cost.
The present invention adopts the following technical scheme that realization：
A kind of biological agent for being used to handle heat and power*.plant wastewater, by large aperture carrier and microbial inoculum according to 10-15:The matter of 2-3
Amount is obtained than mixing；
The large aperture carrier is prepared according to following technique：
（1）By carborundum powder, zeolite powder, lithium bentonite, ferric trichloride, turfy soil, silica white and attapulgite according to 5:
5:4:3:2:2:1 mass ratio is mixed evenly to obtain mixture；
（2）By step（1）Gained mixture is with acrylic sphere according to 2:3 volume ratio is placed in comminutor, is subsequently added into and is accounted for step
Suddenly（1）The particle that grain size is 5mm is made in the polyvinyl alcohol water solution of a concentration of 5wt% of the 6% of gained mixture quality；
（3）By step（2）Gained particle is placed in 100 DEG C of temperature drying 120min, places into sintering furnace and is sintered, heating rate is
10 DEG C/minute, 900 DEG C of sintering temperature, keep the temperature 2 hours, take out, be cooled to room temperature to get；
The microbial inoculum is prepared according to following technique：
Thiobacillus ferrooxidans, Paracoccus denitrificans, Bacillus foecalis alkaligenes, bacillus pumilus and Rhodococcus ruber are trained respectively
A concentration of 1 × 108The bacterium solution of a/ml, then according to 5:3:2:1:1 weight ratio mixing, obtains mixed bacteria liquid；Again by Mixed Microbes
Liquid is with sawdust according to 1:1 mass ratio is mixed evenly, and finally carries out low temperature drying, and drying temperature is 20 DEG C, is contained after dry
Water for 8wt% to get；
