The requirements of purification engineering in electronic factory, pharmaceutical factory, operating room and biological laboratory are four broad areas of application of purification engineering, which mainly refer to electronic factory, pharmaceutical factory, operating room and biological laboratory. The requirements of purification control system in different fields are different. At the same time, the control standards in these areas can be widely used in other fields. Industry, such as electronic factory purification engineering control system can be used in PCB production workshop, electrical appliances, injection workshop and so on. The control characteristics of purification engineering in four fields are different as follows:
The cleanliness of electronic factory directly affects the quality of electronic products. Using primary air supply and secondary air supply system, FFU fan filter unit is widely used to purify air layer by layer, reaching 8-level cleanliness in dressing room, 7-level corridor and 6-level in production workshop. Locally, it needs 5-level or 4-level. Static acceptance is required after the completion of the project.
The three objectives of purification control in pharmaceutical factories are cleanliness, six-level standards are widely used in air lock rooms to control no cross-contamination in clean rooms; CFU refers to the number of live bacteria in clean rooms; the project needs GMP recognition; only when the three objectives are completed can it be a qualified purification project, and the project system needs five poles of on-duty fans. It is monitored dynamically by the Drug Inspection Bureau and used after static acceptance.
Operating room control is more stringent, using MAU + AHU system, air supply ceiling 3m*3m, 1000 grade purification level, acceptance criteria for static acceptance, dynamic acceptance of temperature, humidity, CFU.
Usually, the infection rate of patients during operation is 25%. According to statistics, the infection rate of operation is 10%-15%. Many hospitals use the infection rate of routine operation as a good index to evaluate the cleaning project of operating room.
The characteristics of purification engineering control in biosafety laboratory have been formulated in our country. Biosafety isolation clothing and independent oxygen supply system are selected for engineering purification equipment. After tightness test treatment, closed isolator and negative pressure secondary barrier system are adopted for uniform purification of waste liquid and exhaust gas to ensure personal safety. Purification management of biological laboratory.
