Overview

The hospital sewage treatment dosing device selects the materials of each component of the dosing device (stainless steel, carbon steel, non-metallic materials), the model of the metering pump (diaphragm pump, plunger pump), or the parameters of the supplied chemicals (name, concentration, temperature, density, viscosity, corrosiveness, etc.) as needed.

　　Hospital sewage treatment dosing device

The phosphorus in sewage comes from fertilizers and agricultural waste. At the same time, the extensive use of phosphorus containing detergents in daily life has significantly increased the phosphorus content in domestic sewage. In addition, wastewater discharged from industries such as chemical, papermaking, rubber, dyeing and textile printing, pesticides, coking, petrochemicals, fermentation, pharmaceuticals and medical, and food often contains organic phosphorus compounds. The pollution of soil by phosphorus mainly comes from the excessive use of pesticides, fertilizers, and sewage irrigation. Excessive phosphorus can exceed the soil's self purification capacity, causing adverse changes in the soil and leading to natural dysfunction of the soil. To prevent oxidative fungicides from entering the reverse osmosis membrane and oxidizing the membrane components, a reducing agent dosing system is installed before the reverse osmosis system. The specific dosage should be determined based on the residual chlorine content in the reverse osmosis system after adding the oxidizing bactericide. Generally, it is about 3-5 times the residual chlorine content, calculated based on a dosage of 2ppm. The daily dosage of the desalinated water treatment system is approximately 5.76 kilograms (calculated based on 120m3/h of inlet water), calculated as the concentration of the reagent multiplied by the inlet water for 24 hours. It is important to note that excessive addition of the reducing agent can also cause system fouling. Therefore, it is necessary to strengthen daily residual chlorine monitoring work to adjust the dosage ratio between the oxidizing sterilizing agent and the reducing agent, so that the reducing agent can fully react the damage of the oxidizing substance to the membrane components without causing additional pollution to the system due to excessive residual amount.

　　Structure of hospital sewage treatment dosing device

1. Compact structure and good overall integrity. This device integrates the dosing metering pump, supporting pipeline valves, pressure gauges, solution tanks, liquid level gauges, and corresponding electrical controls into a single frame base, which can be flexibly and conveniently combined into various chemical dosing treatment units for different purposes, completing the dissolution, preparation, and injection of drug solutions;

2. There are various forms such as two pump one box, three pump two box, four pump two box, five pump two box, etc;

3. Configure a metering pump with a flow range of 5-980L/h and a pressure range of 1.0-26Mpa;

The dosing device and its supporting components can be purchased and manufactured according to national standards, as well as API, ASME, SSPC, IEC, ASTM, ANSI and other standards.
