Design and calculation formula for hospital sewage treatment equipment (medical sewage treatment equipment)

According to the functions, facilities and personnel composition of various departments of the hospital, the main departments and facilities for generating sewage include: diagnosis and treatment room, laboratory, ward, laundry room, X-ray image printing, animal room, isotope treatment diagnosis, operating room, etc. Hospital administrative management and medical staff discharge domestic sewage, canteens, single dormitory, family dormitory drainage;; different departments of the department produce different sewage components and water, such as heavy metal wastewater, oily wastewater, printing wastewater, radioactive wastewater, etc. The sewage produced by hospitals of different natures is also very different. Hospital sewage is more complicated than ordinary domestic sewage discharge. After the sewage treatment in hospitals, the discharge is divided into two categories: discharge into natural water bodies and discharge into urban sewage treatment plants through municipal sewers.

First, hospital sewage discharge

1. New hospital

The discharge of sewage from new hospitals should be designed according to the "Technical Measures for the Design of Civil Building Engineering" [2003] No. 4 to achieve clearing and diversion, and save water.

2, the existing hospital

1) The amount of sewage discharged is determined based on the measured data.

2) When there is no measured data, please refer to the following data calculation

(1) Large-scale hospitals with full equipment or hospitals with more than 500 beds: the average daily sewage volume is 400-600L/bed.d, kd=2.0-2.2, and kd is the daily variation coefficient of sewage.

(2) Medium-sized hospitals with general equipment or 100-499 bed hospitals: the average sewage volume is 300-400L/bed.d, kd=2.2-2.5, kd is the daily variation coefficient of sewage.

(3) Small hospitals (less than 100 beds): The average sewage volume is 250-300L/bed.d, kd=2.5, and kd is the daily variation coefficient of sewage.

3. Calculation formula for hospital sewage design water quantity:

(1) Calculated according to the water quota and hourly coefficient of change:

among them:

Q1, q2 - the maximum daily water quota for the inpatient department and the outpatient department, L/person•d.

Q3 - unforeseen water volume, L/s.

N1, N2 - number of people in the inpatient department and outpatient department.

Kz1, Kz2 - hourly coefficient of variation.

(2) Calculated according to the reference daily average sewage volume and daily variation coefficient:

among them:

q ——The average daily sewage volume of the hospital, L/bed•d.

N - the number of beds in the hospital.

Kd - the daily variation coefficient of sewage.

P16 Led Display

Produce the designed circuit board, then paste all the driver ICs, prepare all the corresponding LEDs, and then prepare to start the assembly line to start the operation. The AI vertical machine starts to insert the lights, the DIP starts, and all the LEDs Knit the tape, then put it in the Universal vertical machine, start to insert the LED directly, according to the set procedure, insert the entire LED board.
After all the completed P16 full-color display modules have passed the company's quality management inspection, and there are no problems, the product is put into wave soldering, and then all the LED pin tubes are completely soldered. The environmental protection is used. Lead tin.
All the soldered full-color display modules begin to work on the assembly line. All accessories, such as the angle of the signal line of the line driver, and various power sockets, and the entire light board, if there are any, crooked The oblique LED lamp bead will right and level the LED lamp bead for comprehensive inspection.
The color of the lamp beads of the P16 module can be customized. The module can be used in a single module or in a combination of multiple modules. When multiple modules are used in combination, the positive pole of the power cord between the two modules is connected to the positive pole (red ), the negative pole is connected to the negative pole (black); the signal is connected through the signal line.
