Processing device and processing method for removing nitrate from ground water

Abstract

The invention discloses a processing device for removing nitrate from ground water, which mainly comprises a water outlet pipe, a quartz sand filter unit, a backwash water inlet pipe, a magnetic ion exchange (MIEX) resin processing unit, a water inlet, a first peristaltic pump, a second peristaltic pump and an MIEX resin regenerating unit, wherein the top part of the processing device is provided with a water outlet pipe; the quartz sand filter unit is arranged below the outlet pipe; a water distribution pore plate is arranged at the bottom of the quartz sand filter unit; the surface of the water distribution pore plate is covered by water filtering filter cloth; the backwash water inlet pipe is arranged below the quartz sand filter unit, and the MIEX resin processing unit is arranged below the backwash water inlet pipe; the water inlet is arranged at the bottom of the processing device; a water inlet water distribution pore plate is arranged above the water inlet; an outlet for resin to be regenerated of the MIEX resin processing unit is connected with the inlet of the MIEX resin regenerating unit through the first peristaltic pump; and the outlet of the MIEX resin regenerating unit is connected with the inlet for the resin to be regenerated of the MIEX resin processing unit.

Description

technical field [0001] The invention relates to the field of drinking water treatment, in particular to a treatment device and method for safely and efficiently removing nitrate in groundwater. Background technique [0002] Nitrate pollution in drinking water sourced from groundwater has aroused concern in many countries. Due to factors such as agricultural fertilization, leakage of domestic sewage and nitrogen-containing industrial wastewater, leaching and infiltration of solid waste, and recharge of sewage, the nitrate pollution in groundwater in my country is relatively serious, especially in the northern region. Drinking water with high nitrate content can lead to various health problems. The so-called "blue baby syndrome" is caused by the lack of oxygen in the body due to the consumption of food or water containing nitrate in infants and young children, resulting in blue-purple spots on the skin, and Accompanied by symptoms of dyspnea, which can be fatal in severe case...
