The small solvent of his ingredient solubility, a kind of extracting method that required active ingredient is dissolved out out of medicinal material tissue are molten
Most common organic solvent is ethyl alcohol in agent extraction method.
In natural drug extraction process, according to the difference of production kind, the amount of organic solvent used can not yet
Together, COD concentration general range is 142-18000mg/L in the sewage of generation, and institute's blowdown water concentration is all changing when daily, per.
These natural drugs are extracted with sewage disposal mostly based on biochemical process in the country.In recent years, traditional Chinese medicine extraction sewage in pharmaceutical factory was in processing
It is few to run steadily in the long term, especially when sewage plant is discharged into large amount of organic or a large amount of soda acids when factors, sewage
Processing microbes are largely poisoned to death so that sewage treatment facility is not normally functioning, Sewage Disposal must again into
Row bacteria domestication, debugging time can just continue sewage disposal, and this process needs the time or more long of some months, so as to lead
It causes sewage disposal for a long time cannot be up to standard, while influences production and be normally carried out.Therefore, it is badly in need of developing a kind of suitable for natural drug
Sewage disposal regulating system is extracted, so that sewage can be handled efficiently.
The content of the invention
Sewage disposal regulating system is extracted for natural drug the present invention provides one kind, solves Chinese medicine in the prior art
Factory's traditional Chinese medicine extraction sewage is often discharged into the factors such as large amount of organic or a large amount of soda acids because of sewage plant, causes sewage disposal microorganism
The problem of being poisoned, be dead, being not normally functioning sewage disposal.
First purpose of the present invention is to provide a kind of natural drug that is used for and extracts sewage disposal regulating system, including successively

When the second detection interior COD concentration<During 2100mg/L, the high-concentration sewage stored in transfer pond is by automatically controlling
Program is pumped into regulating reservoir through Sewage metering；
Wherein, the sewage quantity that the high-concentration sewage stored in the transfer pond is sent into regulating reservoir is calculated according to formula below：
It sets in the second detection cell COD of sewage and monitors concentration value on-line as c1, liquid level is h1 in regulating reservoir, regulating reservoir
Floor space for s1, then sewage volume v1=h1 × s1 in regulating reservoir, COD total amounts w1=c1 × v1 in regulating reservoir；
Sewage in transfer pond is set to be mixed into after regulating reservoir COD aimed concns c2 in regulating reservoir, as 2500mg/L, transfer pond turns
Enter sewage volume v2 in regulating reservoir, COD on-line monitoring concentration is c3 in transfer pond, is obtained according to the principle of mass conservation；
2500 × (v1+v2)=w1+v2 × c3,
Wherein, c1 is monitored to obtain by the 2nd COD on-line detectors, and c3 is monitored to obtain by the 3rd COD on-line detectors, h1 and
S1 is obtained by measurement；
V2 values are calculated according to above formula, the v2 is that transfer pond is transferred to sewage volume in regulating reservoir；
When detecting in the first detection cell COD concentration≤2500mg/L in sewage and pH value is 6-9, in the first detection cell
Sewage enters regulating reservoir；It is 20-24h to set hydraulic detention time in regulating reservoir, and be disposed adjusted pond water outlet；
Step 3, regulating reservoir water outlet enters PEIC anaerobic reactors, and it is 10- to set PEIC anaerobic reactor internal volumes load
12KgCOD/(m3D), hydraulic detention time 6-8h is disposed to obtain PEIC anaerobic reactor water outlets；
Step 4, PEIC anaerobic reactors water outlet water outlet enters contact-oxidation pool, contact-oxidation pool internal volume load 1-
2KgCOD/(m3D), hydraulic detention time 4-6h is disposed to obtain contact-oxidation pool water outlet；
Step 5, touch oxidation pond water outlet to enter secondary settling tank and precipitated, precipitate secondary settling tank supernatant qualified discharge after 1-2h,
Complete the processing procedure.
Preferably, when detecting COD of sewage concentration >=2500mg/L in regulating reservoir, microbial nutrition member feeding port is passed through
Nutrition member is added in regulating reservoir.
Compared with prior art, the beneficial effects of the present invention are：
1) present invention sets the first detection cell on-line checking COD concentration and pH value, dirty when detecting COD concentration over-standards
Water is discharged into transfer pond and keeps in, and afterwards by calculating, it is mixed into regulating reservoir by a certain amount of, participates in sewage disposal system, makes
Testing index is not exceeded, it is ensured that follow-up sewage disposal normal operation；When pH value is exceeded, medicament is neutralized by adding in, ties up pH value
Hold normal level.
2) present invention sets the second detection cell on-line checking COD concentration, when detecting COD concentration over-standards, stops backward
Continuous biology aerobic pond water inlet, while the second detection water is back to regulating reservoir, flows self-circulation sewage in system, water quality is risen
To part that can be removed COD while mixing homogeneous.In addition, it is thus also avoided that the poisoning of sewage disposal microorganism, dead, the follow-up life of holding
Change bioactivity in processing unit, sewage disposal system can be made to run steadily in the long term, it is ensured that sewage disposal qualified discharge and enterprise
Industry production is normally carried out.
3) high treating effect of the invention, it is efficient, it has good stability, is handled by sewage disposal regulating system of the present invention
