Description
Technical Field
The invention belongs to the technical field of wastewater treatment, and particularly discloses a method for reducing biotoxicity of antibiotic wastewater through a membrane material.
Background
Antibiotics refer to a class of secondary metabolites with anti-pathogen or other activities generated by microorganisms (including bacteria, fungi, actinomycetes) or higher animals and plants during life, and chemical substances capable of interfering with other life cell development functions. Antibiotics commonly used in clinical practice include extracts from microbial cultures and chemically synthesized or semisynthetic compounds.
The antibiotic is prepared by fermenting, filtering and refining organic raw materials such as grains and the like through the vital activity of microorganisms by adopting a fermentation process, and has the characteristics of high COD (chemical oxygen demand) and ammonia nitrogen concentration, high chromaticity, high sulfate concentration, difficult biodegradation of contained pollutants, biotoxicity and the like in the process of producing the antibiotic. During the process of discharging the waste water, some antibiotics are wrapped in the sludge, and if the sludge is not filtered from the waste water, more antibiotics are discharged into the environment along with the waste water, so that the pollution to the environment is increased.
Disclosure of Invention
The invention aims to provide a method for reducing the biotoxicity of antibiotic wastewater through a membrane material, so as to solve the problem that the antibiotic is wrapped in sludge and increases the environmental pollution along with the discharge of the wastewater.
In order to achieve the purpose, the basic scheme of the invention is as follows: a method for reducing the biotoxicity of antibiotic wastewater by a membrane material, which comprises the following steps:
(1) taking wastewater containing sludge, adding acid into the wastewater, and adjusting the pH of the wastewater to 3-4;
(2) enabling the wastewater in the step (1) to pass through a filtering membrane, extruding the wastewater when the wastewater passes through the filtering membrane, adding alkali to adjust the pH value of the wastewater to 7-8 after the wastewater passes through the filtering membrane, and discharging the wastewater after the wastewater reaches the standard;
(3) and (3) drying the sludge on the filtering membrane in the step (2) by using hot air, and removing the sludge on the filtering membrane.
The working principle and the beneficial effects of the basic scheme are as follows:
(1) the method can inactivate part of antibiotics in the wastewater after adding the acid into the wastewater, and can generate precipitates at the same time, so that the sludge and the precipitates can be conveniently mixed together for cleaning;
(2) in the method, the sludge is air-dried by using hot air, so that the sludge is prevented from continuously remaining in the wastewater to influence the subsequent treatment of the wastewater;
(3) the method can effectively remove the sludge contained in the water, reduces the content of antibiotics in the water and reduces the pollution of the antibiotics to water resources.
Further, the acid added in the step (1) is one of sulfuric acid, nitric acid or hydrochloric acid. Partial antibiotics in the wastewater can be inactivated by adding acid, and heavy metal ions in the wastewater can be precipitated, so that the pollution of the wastewater to the environment is reduced.
Further, in the step (3), hot air is blown to the filtering membrane from the water outlet side of the filtering membrane, the sludge on the filtering membrane is dried by the hot air, and the dried sludge is blown away. After the sludge is dried, the sludge can form a sheet shape or a block shape, and the dried sludge is convenient to clean.
Further, stirring and heating are carried out during the process of adding the acid into the wastewater in the step (1). The wastewater is heated in the acid adding process so as to remove microorganisms in the water, and the pollution to the water body is reduced.
Further, the filtering membrane used in the step (2) is a filtering membrane made of polycarbonate, polyvinyl chloride, polyvinylidene fluoride, polysulfone, polyacrylonitrile, polyamide, polysulfone amide, sulfonated polysulfone, cross-linked polyvinyl alcohol or modified acrylic acid polymer material.
