Embodiment 1
[0019] Biological laboratory waste liquid treatment method of the present invention, carry out according to the following steps:
[0020] The first step is to pass the collected biological laboratory waste liquid through a centrifuge to separate the solid and liquid in the waste liquid;
[0021] In the second step, the solid separated in the first step is sterilized and packaged; the separated liquid is introduced into the container for ultraviolet disinfection, that is, the liquid is introduced from the bottom of the container and then discharged from the top of the container for collection. The container is insulated from top to bottom and multi-layer ultraviolet emitting lamps are installed to sterilize and disinfect the liquid entering the container; the ultraviolet intensity is greater than 30000μW / cm 2 , the ultraviolet rays emitted by the multi-layer ultraviolet emitting lamp tube with a wavelength of 200-290nm can penetrate the cell membrane of bacteria and viruses in ...
Embodiment 2
[0023] Biological laboratory waste liquid treatment method of the present invention, carry out according to the following steps:
[0024] The first step is to use a filter membrane (1-10 μm) to separate the solid and liquid in the waste liquid collected from the biological laboratory;
[0025] In the second step, the solid separated in the first step is sterilized and then packaged; the separated liquid is sterilized by ozone, that is, the liquid is pumped to the sprayer on the top of the container, and at the same time put in the container Ozone gas with a concentration greater than 8ppm, when the liquid is sprayed downward from the sprayer on the top of the container, convects with the ozone moving upward from the bottom of the container, so as to realize the complete sterilization of the liquid; the sterilized liquid flows from the bottom of the container The drain discharge is collected for utilization.
Embodiment 3
[0027] Biological laboratory waste liquid treatment method of the present invention, carry out according to the following steps:
[0028] The first step is to separate the solid and liquid in the collected biological laboratory waste liquid by heating and evaporating. The collected biological laboratory waste liquid is transported to a container with a steam outlet on the top and passed through a microwave generator. Heating and evaporating, the heated water vapor is discharged from the steam outlet, enters the condenser and is cooled to liquid, and the solid remains in the container;
[0029] In the second step, the solid separated in the first step is sterilized and packaged; the separated liquid is first sterilized by ultraviolet rays, and then sterilized by ozone again. Continuous sterilization can have a better treatment effect on waste liquid.
