Description
Technical field
The invention belongs to technical field of waste water processing, specifically disclose a kind of by membrane material reduction antibiotic waste water biology
The method of toxicity.
Background technique
Antibiotic refers to the institute in life process by microorganism (including bacterium, fungi, actinomyces) or high animals and plants
What is generated has antipathogen or other active a kind of secondary metabolites, can interfere the change of other living cells development functions
Learn substance.Existing clinically used antibiosis is known as extract and chemically synthesis or semi-synthetic in microbial culture medium
Compound.
Antibiotic is the more bio-pharmaceuticals of current domestic application, using zymotechnique, by the vital movement of microorganism,
The Organic Ingredients such as grain are fermented, filtered, are refined, the waste water COD and ammonia nitrogen generated during producing antibiotic
Concentration is high, coloration is big, sulfate concentration is high, contained pollutant is difficult to biodegrade and has the characteristics that bio-toxicity.It is discharging
During waste water, some antibiotic are wrapped in sludge, if sludge not filtered from waste water, it will there is more antibiosis
Element is discharged in environment with waste water, will increase the pollution to environment in this way.
Summary of the invention
The purpose of the present invention is to provide a kind of methods for reducing antibiotic waste water bio-toxicity by membrane material, to solve
Antibiotic is wrapped in sludge and the problem of increasing environmental pollution is discharged with waste water.
In order to achieve the above object, base case of the invention are as follows: a kind of that antibiotic waste water biology is reduced by membrane material
The method of toxicity, comprising the following steps:
(1) waste water containing sludge is taken, acid is added into waste water, adjusts the PH to 3-4 of waste water；
(2) waste water in step (1) is squeezed into waste water when waste water passes through filter membrane, waste water passed through by filter membrane
The PH to 7-8 that alkali adjusts waste water is added after filter membrane, is discharged after up to standard to wastewater recycle；
(3) by sludge hot blast drying on filter membrane in step (2), the sludge on filter membrane is removed.
The working principle and beneficial effect of this base case is:
(1) this method can inactivate the antibiotic part in waste water after acid is added in waste water, while can generate precipitating, just
It admixed together is cleared up in by sludge and precipitating；
(2) it uses hot wind by sludge air drying in this method, prevents sludge from continuing to remain in waste water to subsequent processing waste water
It has an impact；
(3) sludge contained in water can be effectively removed using this method, the antibiotic content contained in less water reduces
Pollution of the antibiotic to water resource.
Further, the acid being added in step (1) is one of sulfuric acid, nitric acid or hydrochloric acid.It can be by waste water by the way that acid is added
In the inactivation of part antibiotic, while the heavy metal ion in waste water can also be precipitated, reduce dirt of the waste water to environment
Dye.
Further, from the side that filter membrane is discharged to filter membrane blowing hot-air in step (3), hot wind is by the sludge on filter membrane
It air-dries and the sludge after air-drying blows off.After drying sludge, sludge can be made to form sheet or bulk, convenient for the dirt after drying
Mud is cleared up.
Further, it is stirred and heats during acid is added in step (1) into waste water.To waste water acid adding process
In simultaneously carry out heating convenient for remove water in microorganism, reduce the pollution to water body.
Further, filter membrane used in step (2) is polycarbonate, polyvinyl chloride, Kynoar, polysulfones, poly- third
Alkene nitrile, polyamide, polysulfonamides, sulfonated polysulfone, the polyvinyl alcohol of interlinkage or modified acrylic polymer material filter membrane.
