Problems solved by technology

However, the conventional water purification treatment process (coagulation + sedimentation + filtration + disinfection) cannot effectively remove organic matter, ammonia nitrogen and other pollutants in slightly polluted source water, and liquid chlorine can easily combine with humus in raw water to produce disinfection by-products (DBPs) , a direct threat to the health of drinkers, unable to meet people's needs for drinking water safety

Abstract

The invention discloses a micro-polluted water source deep treatment and purification system and method. The system comprises a regulation pool, an ozone pre-oxidation tower, a magnetic loading and flocculation system and an ozone-biological activated carbon filter system; and the magnetic loading and flocculation system is also connected with a medicament blending and dosing system and a magnetic powder recovery and sludge treatment system. The method comprises the following steps: I, pre-oxidation; II, flocculation reaction; III, magnetization; IV, growing to be mature; V, natural settling; VI, mud-water separation; VII, oxidation and disinfection; VIII, physical adsorption; IX, disinfection; and X, delivery to a user. The micro-polluted water source deep treatment and purification system and method integrate magnetic loading and flocculating sediment, ozone-biological activated carbon filter and a conventional water purification and treatment process to form an efficient deep treatment and purification process system.

Description

technical field [0001] The invention relates to an advanced treatment and purification system and method for slightly polluted water sources, belonging to the technical field of drinking water treatment. Background technique [0002] In recent years, with the continuous development of the economy, especially the rapid growth of the production industries such as organic chemicals, petrochemicals, pharmaceuticals, pesticides, insecticides and herbicides, the output and types of organic compounds have continued to increase. Various industrial wastewater and domestic sewage Many water sources have been polluted to varying degrees, and the social problems caused by the continuous deterioration of water sources have become more and more obvious. Water resource protection measures have become a key issue related to the development of my country's people's livelihood. [0003] In order to ensure the sanitation and safety of water supply in my country, the promulgation and implementat...
