Abstract
The invention discloses a method for treating waste liquor of a biology laboratory, which comprises the following steps: 1, separating solid from liquid in the collected waste liquor of the biology laboratory by adopting a centrifugal machine, a filtering membrane or a heating evaporation method; and 2, sterilizing and packaging the solid separated in the step 1, introducing the separated liquid into a container, sterilizing by ultraviolet rays or/and ozone, and collecting for recycling. The method has the advantages that: after the waste liquor is subjected to integrated collection and treatment, waste water can be recycled, and the water-saving effect is obvious; and the separated solid matter is packaged and not arranged and placed disorderly, so that environmental pollution is lightened.
Description
Technical field
The present invention relates to method for treating waste liquid, especially relate to method for treating waste liquor of biology laboratory.
Background technology
In each test link of biology laboratory, can produce the waste liquid that contains complicated composition (bacterium, virus, heavy metal, ion, organic compound, grease etc.) in a large number, the processing to these waste liquids is directly to pour or flow into water drain at present.This simple processing mode has caused pathogenic bacteria to grow breeding and has propagated, corrosion is caused in laboratory and other underground water offtake piping systems, also polluted the water source simultaneously, destroyed soil property and ecotope etc., human health and ecotope have been caused direct or indirect destruction and influence.
Summary of the invention
The object of the invention is to provide a kind of method for treating waste liquor of biology laboratory of promptly protecting environment, also useful resource being recycled.
For achieving the above object, the present invention can take following technical proposals:
Method for treating waste liquor of biology laboratory of the present invention, it carries out according to following step:
The first step, adopt whizzer, filtering membrane or heating evaporation method to make solid and liquid separation in the waste liquid biology laboratory waste liquid of collecting;
The processing of behind sterilization and disinfection, packing of second step, the solid that the first step is separated; The liquid of separating imported to take ultraviolet ray in the container or/and recycle is collected in ozone sterilization sterilization back.
The solid-liquid separation of the described the first step is taked the heating evaporation mode, that is: the biology laboratory waste liquid of collecting being transported to the top has in the container of vapour outlet, carry out heating evaporation by microwave generator, water vapour after the heating is discharged from described vapour outlet, and entering the condenser internal cooling is liquid.
In described second step liquid of separating is taked ultraviolet radiation for sterilizing and disinfecting, that is: described liquid is imported the back from container bottom and discharge from container top and collect, insulation from top to bottom is provided with multilayer ultraviolet ray emission fluorescent tube the liquid that enters in the container is carried out sterilization and disinfection in container; Uitraviolet intensity is greater than 30000 μ W/cm
2
In described second step liquid of separating is taked the ozone sterilization sterilization, that is: with described liquid pumping in the spray thrower that is arranged on container top, simultaneously in container, put into the ozone gas of concentration, the liquid that sprays in spray thrower is carried out sterilization and disinfection greater than 8ppm; Liquid behind sterilization and disinfection is discharged from the container bottom water port and is collected.
In described second step liquid of separating is at first taked ultraviolet radiation for sterilizing and disinfecting, take the sterilization of ozone re-sterilise then.
The invention has the advantages that waste liquid carried out integrated collection and handle after, waste water can be recycled, water-saving result is obvious, isolated solid matter packing is handled, no longer disorderly row leaves about, and has alleviated environmental pollution.
In the time of will carrying out disinfection through the isolated liquid of solid, liquid tripping device, can adopt disinfection by ultraviolet light or utilize ozone to carry out disinfection.
Adopt disinfection by ultraviolet light, the wavelength of the multilayer ultraviolet ray emission fluorescent tube emission that is provided with in the container is that the ultraviolet ray of 200～290nm can be carried out breakthrough process to the cytolemma of bacterium, virus in the liquid, its nucleic acid (DNA) is damaged, thereby make cell lose fecundity, with realize rapidly and efficiently, the purpose of pollution-free sterilization.
The sterilization of employing ozone sterilization, liquid forms convection current with the ozone that moves upward from container bottom in the spray process downwards from the spray thrower of container top, thereby realizes the thorough sterilization and disinfection to liquid.
If adopt the continous way sterilization and disinfection, promptly earlier use ultra-violet sterilization, adopt ozone to carry out the re-sterilise sterilization again, then the germicidal treatment to biology laboratory liquid is more thorough.
In sum, the treatment process to the biology laboratory waste liquid of the present invention is simple, practical, and waste collection is integrated with processing, and equipment volume is little and efficient is high, and strong to the liquid waste disposal ability, running cost is low; Waste liquid is after solid, liquid separates, and solid is handled through the sterilization packing, and liquid can be recycled after treatment, has saved precious water resource, has reduced the waste of water, has also avoided the pollution of waste liquid to environment simultaneously.
