working principle:
After inflating or adding oxidants to groundwater containing iron (manganese), iron (manganese) ions in the water begin to oxidize. When the water flows throughManganese sandDuring the filtration process, contact oxidation reactions occur within the filter layer, as well as biochemical and physical interactions on the surface of the filter materialThe interception adsorption effect causes the precipitation and removal of iron (manganese) ions in water. Especially in the process of treating micro polluted manganese containing groundwater, iron bacteria can not only effectively remove iron and manganese, but also use ammonia in the water as a nutrient source for new agingThanks, with the participation of other bacteria, the effect of removing ammonia nitrogen was achieved simultaneously.
technological process:
1. When the concentration of iron ions in groundwater is only5-10mg/LAt that time, a series process of aeration device and iron removal filtration can be used. Due to the small volume of the aeration device (similar to a pipe), this process is actually a single-stage treatment process mainly composed of manganese sand.
2. If the iron ion content in groundwater is high and contains manganese, that is, the iron content is greater than10mg/LThe manganese content is greater than0.5mg/LWhen, it is advisable to use additionoxidantThe process flow of equipment and iron (manganese) removal in series.
If the quality of groundwater containing iron and manganese is complex, such asPHThe value and alkalinity are low, and the silica content is high. To ensure the treatment effect, users are requested to provide water quality inspection reports or raw water samples, so that corresponding measures can be taken according to different water qualities.
The regulating water tank in the process flow serves as a mixing reaction tank for dissolution oxidation and raw water, as well as a suction regulating structure for the pressure pump. If the feed water pressure of the deep well pump can meet the requirements of the iron (manganese) removal device, there is no need to set up a regulating water tank and a booster pump.
3. Single flow mechanical filtration equipment can remove iron, manganese, and suspended solids from water, mainly used for:Softening, desalination systems, and pre-treatment processes for industrial water supply. The filter material is refined quartz sand, manganese sand anthracite. The main materials of the equipment are anti-corrosion carbon steel, fiberglass, stainless steel, etc.
