Description
Technical field:
The invention belongs to field of environmental improvement, and in particular to one kind includes Meng Shi pseudomonad (Pseudomonas
Monteilii) the preparation method of the biological active filling material of LW-1.
Background technique:
Waste water in pesticide producing contains a large amount of organosulfur pesticide and organo-chlorine pesticide intermediate, complicated component, concentration
High, strong toxicity.The product or in which mesosome of part organosulfur pesticide and organo-chlorine pesticide such as parathion, malathion, methyl pair
Sulphur phosphorus, trichloroacetaldehyde, phosphorus trichloride etc., have a volatility, and most of organic sulfur and organo-chlorine pesticide have it is pungent
Peculiar smell.
Parathion (C10H14NO5It PS) is colourless oil liquid, solubility is 24mg/L (25 DEG C) in water.It is slightly soluble in petroleum ether
And kerosene, there can be garlic odour with most immiscible organic solvents.It is promptly hydrolyzed in alkaline medium；In neutral or slightly acidic solution
In it is relatively stable；It is all unstable to ultraviolet light and air.There are mutagenicity and animal teratogenesis to microorganism.Belong to hypertoxic type, tool
There are acute toxicity, irritation, mutagenicity.Human lymphocyte Sister chromatid exohange is influenced when 200 μ g/L；10μmol/L
When influence human fibroblasts unscheduled DNA synthesis；When 10 μm of ol/L, rat lymphocyte DNA damage, IARC are made in 16 hours
Carcinogenicity is evaluated as G3 grades；The minimum toxic dose of rat oral (TDLo): 360 μ g/kg (pregnant 2~22d/ postpartum 15d) influence new
Raw mouse is biochemical and is metabolized；The minimum toxic dose of subcutaneous rat (TDLo): 9800 μ g/kg (pregnant 7~13d), lethal tire.Parathion energy
Enter human body by alimentary canal, respiratory tract and complete skin and mucous membrane.Parathion in environment can also be sent out by food chain
Raw biological concentration.
Malathion (C10H19O6PS2) it is colourless or pale yellow oily liquid, there is garlic smell.Chance open fire, high fever is flammable；With
Strong oxidizer reacts；Phosphorus, sulfur oxide gas are generated by thermal decomposition；It is toxic to animal, it is irritating to eyes, skin
Property；Active in 5.0 or less pH, pH7.0 or more is easy hydrolysis failure.Female mice acute oral LD50 is 1751.5mg/kg, male
Rat acute LD50 is 1634.5mg/kg, and the percutaneous LD50 of rat acute is 4000~6150mg/kg.Poisoning symptom is head
Bitterly, dizziness, nausea, inability, hidrosis, vomiting, salivation, eye-blurred, myosis, spasm, stupor, flesh fibrillation, pulmonary edema etc..
Generally morbidity is very fast after contact in a short time (oral, sucking, skin, mucous membrane) a large amount of organophosphorus pesticides.Malathion poisoning is dived
The volt phase is longer.It absorbs through skin, falls ill in 12h, poisoning symptom shows as appetite stimulator, Nausea and vomiting, abdominal pain, hidrosis, thing
Object is fuzzy, myosis, respiratory secretions increase, bronchial spasm expiratory dyspnea, pulmonary edema；Sample Symptoms are muscle bundle shake
It quivers, muscle spasmus, myoparalysis；Central nervous system symptom shows as headache, dizzy, insomnia drowsiness, out of strength, irritated, twitch living, dusk
Fan, brain edema.The state of an illness is heavier when oral ingestion, and gastrointestinal symptom becomes apparent from.Some cases can have cardiac muscle, liver, renal damage.
Parathion-methyl (C8H10NO5PS): colorless crystalline powder, industrial goods are brown or yellow liquid or solid, are met bright
Fire, high fever is flammable, by poisonous gas such as thermal decomposition release phosphorus, sulfur oxides, can decompose rapidly in lye.To big white mouse urgency
Property LD50 of passing through mouth be 14~24mg/kg, to rabbit acute percutaneous LD50 be 300~400mg/kg, belong to high toxic pesticide.Methyl is to sulphur
Phosphorus tool is tagged and stomach poison function, can inhibit the vigor of cholinesterase in pest nervous system and lethal, and insecticidal spectrum is wide, is often processed into
Missible oil or pulvis (see the formulations of pesticide) use, and are mainly used for prevention and treatment various agricultural pest.It is prominent with certain cause to microorganism
Denaturation, such as 667 μ g/ ware of salmonella typhimurium；Escherichia coli: 10mmol/L.Gaseous state, mist state, aerosol state or powdery
It is easily absorbed for respiratory tract, liquid can be through eye mucous membrane, skin or gastrointestinal tract.Into after in vivo, distribution to each device of whole body rapidly
Official's tissue, and be firmly combined with histone.
Organo-chlorine pesticide is one of current most popular insecticide, is occupied an important position in pesticide market.So
And in organo-chlorine pesticide production and agricultural chemicals waste water treatment process, there is volatile Pesticidal products or intermediate, waved from liquid phase
Hair, spills into air, forms air pollution.
Volatile pesticide and intermediate include: metrifonate, DDVP, phosphorus trichloride, dichlobenil, herbicide, thimet,
Phoxim, biphenyl, BFPO, alkane and alkane substitute class intermediate, aromatic intermediate etc. (choosing organochlorine), these substances
Most of have a pungent smell, some substances such as diethyl phosphite, trichloroacetaldehyde, belong to carcinogenicity, mutagenicity and
The cause property substance of the three of teratogenesis.
It is these organic sulfurs with peculiar smell, organic because being aerated, pushing the mechanical disturbances such as water flow in wastewater treatment process
Chlorine is spilt into air from water, forms odor pollution.If not being subject to processing appropriate, the organochlorine in air is spilt into,
Serious pollution environment, is detrimental to health.
Biotechnology cleans because it has many advantages, such as at low cost, easy to operate, technology, is without secondary pollution, is effective at present
Handle one of the important method containing organic compounds.The principle of biologic treating technique is to utilize the biological oxidation of microorganism will
Organic sulfur conversion is the process of the harmless or low harmful substances such as sulfate, carbon dioxide, water, as follows:
Malathion → carbon dioxide+sulfate+water；
Parathion-methyl → p-nitrophenol+organic sulfate → sulfate+phosphate+carbon dioxide+water；
Parathion → p-nitrophenol+organic sulfate → sulfate+phosphate+carbon dioxide+water.
The principle of biologic treating technique is to convert carbon dioxide, salt for organochlorine using the biological oxidation of microorganism
Hydrochlorate and water etc. be harmless or the process (formula 1) of low harmful substance.
C2HCl3O+O2→CO2+H2O+HCl (formula 1)
Existing research shows that the facultative chemoheterotrophy bacterium in natural environment belongs to pseudomonad (Pseudomonas
Sp.) X2 (201310551914.2), Sphingobacterium (Sphingobacterium griseoflavus) SCU-B140
(201510715812.9), Acidithiobacillus ferrooxidans strain GF (Acidithiobacillus ferrooxidans), thermophilic iron hook end
The mixed culture of spirillum (Leptospirillum ferriphilum) and Ferroplasma acidiphilum
(201310745138.X) etc. has degradation to organosulfur pesticide.But not yet discovery is for handling organic sulfur and organic
The Meng Shi pseudomonad (Pseudomonas monteilii) of chlorine, and use Meng Shi pseudomonad processing sulfur-bearing, contain chlorine pollution
The method of object.
Summary of the invention:
In order to solve, volatility organic sulfur, organochlorine treatment effeciency in the prior art be low, microorganism is on mixed carrier surface
Load is uneven, starting is slow, the problem of filler collapses is used for a long time, and the present invention provides one plant of Meng Shi pseudomonad
(Pseudomonas monteilii), and the bacterial strain is applied to removing containing in organic sulfur, organochlorine exhaust gas.
The Meng Shi pseudomonad, specially Meng Shi pseudomonad (Pseudomonas monteilii) LW-1, be from
It is tamed and dociled in agricultural chemicals waste water containing the organochlorines such as the organic sulfurs such as parathion-methyl, malathion, parathion and phosphorus trichloride, trichloroacetaldehyde
Change, isolated separation bacterium.The bacterial strain is preserved in China Committee for Culture Collection of Microorganisms on March 10th, 2017
