Continuous high-grade biosafety laboratory wastewater inactivating device and method

Abstract

The invention discloses a continuous high-grade biosafety laboratory wastewater inactivating device. the device comprises a wastewater collecting tank, a storage tank, a second electric heater, a refrigerating machine, a second thermometer, a second electric pump, a first electric pump, a pressure meter, a heat exchanger, a first electric heater, a thermal-insulation coil, a flow meter and a firstthermometer. The invention further discloses a continuous high-grade biosafety laboratory wastewater inactivating method. The inactivating device disclosed by the invention can continuously treat wastewater in the wastewater collecting tank. The inactivating method comprises the following steps: firstly, utilizing clean water to test whether an inactivating condition can reach the requirement, and then performing inactivation. The inactivating method strictly controls the biosafety risk, and meanwhile, controls water temperature in the storage tank to be the same as the water temperature in the wastewater collecting tank to ensure temperature control accuracy after pipelines are switched in inactivating; thus, the biosafety risk is reduced, and equipment reliability is improved.

Description

technical field [0001] The invention relates to the field of wastewater treatment equipment, in particular to a continuous high-level biosafety laboratory wastewater inactivation device, and also relates to a continuous high-level biosafety laboratory wastewater inactivation method. Background technique [0002] At present, there are two main methods of wastewater treatment in biosafety laboratories: continuous and sequential batch. Sequencing batch wastewater treatment is to collect wastewater through a collection tank, and then use steam or electric heating to heat it to a certain temperature to achieve inactivation. It consumes a lot of energy, and the heating is uneven and there may be dead angles. Continuous wastewater treatment can achieve continuous wastewater treatment through pipeline heating and inactivation, with relatively small energy consumption and precise water temperature control, but there is a risk of pipeline leakage. Both wastewater treatment methods ha...

Sequencing batch wastewater treatment is to collect the wastewater through the collection tank, and then use steam or electric heating to heat it to a certain temperature to achieve inactivation. It consumes a lot of energy, and the heating is uneven and there may be dead angles.

Continuous wastewater treatment is inactivated by heating the pipeline, which can realize continuous treatment of wastewater, with relatively small energy consumption and precise water temperature control, but there is a risk of pipeline leakage

Both wastewater treatment methods have the problem of biological risk control. Once the treatment is not good, it may cause greater biological risk
