Abstract
The invention belongs to the fields of the water supply and sewage treatment devices, and provides a water treatment device and method aiming at excessive ferrum, manganese, fluorine and arsenic in underground water. The water treatment device consists of a partition oxidizing reaction tank (1), an inclined tube sedimentation tank (2), an upward flow quartz sand rough filter material filter tank (3), a downward flow multi-medium filtering tank (4) and a disinfection and water clarifying tank (5) which are sequentially communicated. The water treatment method adopts such a process flow of aeration, partition oxidizing reaction, inclined tube sedimentation, upward flow filtering, aeration, and downward flow filtering in sequence, and comprises the steps of firstly removing interference of ferrum to manganese and then removing the manganese; and feeding a flocculant in the partition oxidizing reaction tank and feeding a pH regulation agent into a pump to be capable of primarily removing fluorine and arsenic, carrying out two-stage filtering to be capable of ensuring that the water after treatment can achieve the standard. The water treatment device and method can remove the excessive ferrum, manganese, fluorine and arsenic substances in the same one device, and the treatment effect is superior to current sanitary standard of domestic drinking water in China.
Description
technical field [0001] The invention belongs to the field of water supply and sewage treatment devices, and further refers to a water treatment device and method aimed at excessive levels of iron, manganese, fluorine and arsenic in groundwater. Background technique [0002] Groundwater is an important part of water resources. With the improvement of people's living standards and the continuous development of small towns, groundwater resources have received special attention. Groundwater often contains high levels of iron and manganese. In some areas, groundwater also contains fluorine and arsenic, which seriously affects people's use of groundwater. [0003] my country's "Drinking Water Sanitation Standard" (GB5749-2006) stipulates that iron <0.3mg / L, manganese <0.1mg / L, fluoride content shall not exceed 1.0mg / L, and arsenic content shall not exceed 0.05mg / L. When the groundwater exceeds the above-mentioned standards, it should be treated. my country's new "Drinking...
