Biological wastewater inactivation treatment process

Abstract

The invention discloses a biological wastewater inactivation treatment process. The process comprises wastewater collection, wastewater storage and stirring, wastewater filtration, wastewater inactivation, and discharge after wastewater inactivation. According to the process, liquid storage tanks and a buffer tank are arranged between a liquid collection tank and an inactivation tank; the liquid storage tanks has a buffering function, that is, wastewater in the liquid storage tanks can be conveyed to the buffer tank, so as to avoid the phenomenon that when the wastewater discharging quantity of equipment is so large to exceed the capacity of the liquid collection tank, the liquid levels in the liquid storage tanks are too high; moreover, due to the arrangement of the buffer tank, wastewater in the liquid storage tanks can be conveyed to the buffer tank simultaneously, that is, the buffer tank can collect wastewater in a plurality of pieces of equipment arranged in scattered areas; a stirring device is arranged to solve the problem of dirt accumulation in the liquid storage tanks. Therefore, through the adoption of the process, the problems, of the conventional inactivation system, that the dirt is easy to generate at the bottoms of the liquid storage tanks, and wastewater of a system with scattered wastewater generation areas and high wastewater discharge capacity cannot be treated are solved.

Description

technical field [0001] The invention relates to the field of biological wastewater treatment, in particular to a process for inactivation treatment of biological wastewater. Background technique [0002] In pharmaceutical factories such as vaccines or biological agents, research institutes, pharmaceutical factories using cell culture, food factories or research institutes, and blood preparation factories, a large amount of biological wastewater will be generated during experiments and production processes, and biological wastewater contains a large number of bacteria. , protein, and cells and other impurities harmful to the environment, the direct discharge of untreated biological wastewater will affect the surrounding environment. Therefore, in order to prevent infected bacteria, proteins, and cells from being discharged with the wastewater, the biological wastewater is being discharged It must be inactivated before. According to the survey, most of them use chemical agent...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a process for the inactivation treatment of biological wastewater, so as to overcome the fact that the existing inactivation system is prone to produce sedimentation and fouling at the bottom of the liquid storage tank, and cannot disperse or discharge wastewater to the place where wastewater is generated. The problem of treating a large amount of system wastewater
