Abstract

The invention relates to a high-temperature steam biological wastewater inactivation system, and belongs to the field of high-temperature steam inactivation devices. The high-temperature steam biological wastewater inactivation system comprises a wastewater containing device, a storage tank and inactivation tanks which are connected in series through pipelines, wherein the inactivation tanks are provided with a steam discharge pipe and an inactivation drainage pipe. The high-temperature steam biological wastewater inactivation system is characterized in that: an outlet at the bottom of the storage tank is respectively communicated with the two inactivation tanks by connecting pipes; the inactivation tanks are provided with clamping sleeves; the input end of each clamping sleeve is connected with a saturated steam generator by a steam inlet pipe, and the output end of each clamping sleeve is provided with a clamping sleeve steam discharge pipe; a water inlet pipe, a connecting pipe anda steam discharge pipe of the storage tank and the steam inlet pipe, the clamping sleeve steam discharge pipe and an extinguishment drainage pipe of the inactivation tanks are provided with an air-operated valve respectively, and all air-operated valves are connected with a control device; and the control device is used for controlling the two inactivation tanks to run in a batch mode by controlling switches of the air-operated valves. The high-temperature steam biological wastewater inactivation system can realize the batch-type treatment of wastewater, is flexible in control and high in safety factors.

Description

technical field

[0001] The invention provides a device for inactivating microorganisms in wastewater discharged from biosafety laboratories or biopharmaceuticals by using high-temperature steam, especially a high-temperature steam biological wastewater inactivation system. Background technique

[0002] Current status of existing domestic equipment: Before SARS, there were very few third-level biosafety laboratories in my country, and the fourth-level biosafety laboratories were blank. The wastewater treatment is generally collected in sewage buckets together, and then put into high-pressure extinguishers together with other experimental items. Sterilize and sterilize in the bacteria pot and then discharge. After SARS, the construction of biosafety laboratories has been widely carried out, but the treatment of biohazardous wastewater generated by it has not received due attention. According to the survey, most of them adopt the method of adding chemical agents to storage tanks...
