GMP workshop animal feeding room sewerage system process design

Abstract

The invention discloses process design based on a GMP workshop animal feeding room sewerage system. The process design is mainly used for separating and discharging GMP workshop large and medium-sized animal feeding room sewage and is characterized by comprising leak hole cover plate design, sewage interception leak net design and liquid sealing airflow partition design, wherein the leak hole cover plate design is used for achieving the function of system one-time separation, the sewage interception leak net design is used for solving the problem of secondary separation, and the liquid sealing airflow partition design is used for resolving the problem of constant room differential pressure and back flow of the sewage in a sewage discharge pipe during sewage discharge.

Description

technical field [0001] The invention belongs to the technical field of biomedicine, and is especially used for the separation and discharge of sewage in large and medium-sized animal breeding rooms in GMP workshops. The solid-liquid mixed sewage is designed through the leakage hole cover plate, the sewage intercepting leakage net and the liquid seal to block the air flow, etc., so as to realize the The sewage in the animal breeding room is separated and discharged. At the same time, the sewage system also solves the impact of the sewage system on the pressure difference in the room and reduces the problem of later maintenance, which greatly improves the biological safety of the room and reduces the operation and maintenance rate of the sewage system. Background technique [0002] Encouraged by national policies, domestic biopharmaceutical companies are increasing day by day. With the market demand and quality requirements for products, the annual production tasks of GMP produ...

AI Technical Summary

Problems solved by technology

[0002] Encouraged by national policies, domestic biopharmaceutical companies are increasing day by day. With the market demand and quality requirements for products, the annual production tasks of GMP production workshops must not only ensure the quantity, but also ensure the quality. The function of the animal room is to test the finished vaccine. Animal testing confirms the biological safety of its products, and the design and acceptance of the inspection animal room not only needs to strictly enforce laws and regulations, but is also subject to many industry standards. Daily animal breeding excrement is generally a solid-liquid mixture with high viscosity. The discharge is difficult, which puts a certain pressure on the sewage pipes. Some of the sewage after security inspection may also involve biological safety hazards carrying active substances, and special treatment is required. At present, the sewage discharge design of large and medium-sized animal breeding rooms of domestic biopharmaceutical companies Collect and filter drainage for the branches of the drainage ditch, or adopt the front-end straight-through sewage pipe design. These designs are likely to cause frequent blockage of the sewage pipeline or leakage of room air through the sewage facilities during sewage discharge, which greatly increases the later operation cost and maintenance rate of the sewage pipe. The most important thing is that it is difficult to ensure the normal maintenance of the pressure difference between adjacent rooms
