Ultrafiltration-nanofiltration integrated emergency treatment apparatus for emergent pollution of drinking water, and polluted drinking water treatment method

Abstract

The invention relates to a drinking water emergent pollution emergency treatment apparatus and a treatment method thereof, and concretely relates to an ultrafiltration-nanofiltration integrated emergency treatment apparatus for emergent pollution of drinking water, and a polluted drinking water treatment method. The apparatus comprises a raw water tank, a dosing pump, a medicine adding tank, a raw water pump, a filter, an ultrafiltration membrane device, an ultrafiltration produced water tank, a booster pump, a first nanofiltration membrane device, a second nanofiltration membrane device, a concentrated water tank and a nanofiltration produced water tank. The method comprises the following steps: 1, opening a water inlet valve, an inlet water regulating valve, a pressure regulating valve and a nanofiltration concentrated water regulating valve, and starting the raw water pump and the booster pump; 2, regulating the opening degrees of the inlet water regulating valve, the pressure regulating valve and the nanofiltration concentrated water regulating valve; 3, allowing concentrated water outlet water discharged from the second nanofiltration membrane device to enter the concentrated water tank, allowing produced water outlet water discharged from the first nanofiltration membrane device and the second nanofiltration membrane device to enter the nanofiltration produced water tank, and regulating the nanofiltration concentrated water regulating valve; and 4, adding an adsorbent, an oxidant or a precipitating agent when the emergent pollutant concentration of inlet water exceeds a maximum treatment capacity. The apparatus and the method are applied to the field of sewage treatment.

Description

An ultrafiltration-nanofiltration integrated emergency treatment device for sudden pollution of drinking water and method for treating polluted drinking water technical field The invention relates to an emergency treatment device and treatment method for sudden pollution of drinking water. Background technique In recent years, with the development of social economy, the degree of industrialization has become higher and higher, and the ability of human beings to transform nature has become stronger and stronger. The pollution of rivers, lakes, reservoirs, etc. has become increasingly serious, and sudden water pollution occurs frequently. The environment and the life, health and safety of the people have caused serious damage, and the safety of drinking water cannot be guaranteed. In the face of such a severe situation, we must be cautious about frequent sudden water pollution accidents and natural disasters, and pay more attention to the research and development of emergenc...
