Embodiment 1

[0027] Embodiment 1: as figure 1 As shown, the local underground water sulfur addition and purification system includes three-stage pools: the water-drawing pool 1, the reaction pool 2, and the recovery pool 3. Lower than the ground surface, the depth of drawing pool 1 meets the shallow groundwater discharge, the depth of restoration pool 3 does not meet the shallow groundwater discharge, and the reaction tank 2 is higher than the surface, the three stage pools are separated by ridge 4, and the drawing pool 1 and the reaction pool 2 are separated There is a water pump 5, and the reaction pool 2 and the recovery pool 3 are connected by pipelines; the reaction pool 2 is divided into a contact area 2-1 and a reaction area 2-2, the contact area 2-1 is connected to the drawing pool 1, and the reaction area 2-2 It is connected to the recovery pool 3, and the two areas are respectively subjected to two stages of contact purification and reaction purification; the contact area 2-1 and...

Embodiment 2

[0031] Embodiment 2: as figure 1 As shown, the shallow groundwater sulfur addition and purification system includes three stage pools: water-drawing pool 1, reaction pool 2, and recovery pool 3. Each pool uses soil as the pool bottom and pool wall, and uses geomembrane to separate water. Pool 3 is lower than the ground surface, the depth of drawing pool 1 is sufficient for the discharge of shallow groundwater, the depth of restoration pool 3 is not sufficient for the discharge of shallow groundwater, and the reaction tank 2 is higher than the surface. There are water pumps 5 in the 2 rooms, and the reaction pool 2 and the recovery pool 3 are connected by pipelines; -2 is connected to the recovery pool 3, and the two areas are respectively subjected to two stages of contact purification and reaction purification; the contact area 2-1 and the reaction area 2-2 are separated by a retaining wall 6, and the bottom of the contact area 2-1 One side is laid with collecting pipe 7 alo...

Abstract

The invention belongs to the technical field of underground water purification and discloses an underground water sulfur-added purification system and a method for purifying shallow groundwater by the same. The system comprises a water drawing pool, a reaction pool and a recovery pool, bottoms and walls of the pools are made of earth while geomembranes are adopted for water isolation, the water drawing pool and the recovery pool are lower than the ground surface, depth of the water drawing pool meets shallow groundwater outflowing while depth of the recovery pool does not meet shallow groundwater outflowing, and the reaction pool is higher than the ground surface and partitioned into a contact area and a reaction area by a retaining wall. A collection pipe with pores and a mountain sand and sulfur mixed filler layer are laid at the pool bottom of the contact area, the collection pipe is connected with a water outlet pipe and penetrates a partition ridge to be communicated with the reaction area, and purification plants are planted at the bottom of the recovery pool with a silt layer. The shallow groundwater is collected through the water drawing pool, subjected to contact purification in the contact area of the reaction pool, then subjected to reaction purification in the reaction area through the collection pipe and the water outlet pipe and finally enters the recovery pool to realize biological purification to finish underground water purification. The system and the method have advantages of structural simplicity, availability for onsite arrangement, great purification effects and the like.

Description

technical field [0001] The invention relates to a groundwater sulfuration purification system and a method for purifying shallow groundwater, belonging to the technical field of groundwater purification. Background technique [0002] In addition to greenhouses, agricultural non-point source pollution in the lakeside area also exists in some exposed areas. In addition to high nitrate nitrogen, shallow groundwater also has low nitrate nitrogen pollution. However, the existing shallow groundwater treatment technology is mainly aimed at the removal of high-concentration nitrate nitrogen, and there are few purification technologies for low-concentration nitrate nitrogen, and the purification effect is not ideal. This technology is mainly aimed at the purification of shallow groundwater when the concentration of nitrate nitrogen is low. Contents of the invention [0003] The technical problem to be solved in the present invention is to propose a groundwater sulfuration purific...
