Embodiment Construction

[0013] Take 10 liters of polluted groundwater containing 85 micrograms per liter of nitrobenzene, add 10 grams of ground carbonized rice husk to the water, stir evenly with a clean wooden stick or a small shovel for 30 minutes, and then add 400 mg of polymerized chlorine at the same time Aluminum chloride and 50 mg of ferric chloride were stirred rapidly for 1 minute, then stirred slowly for 10 minutes, then statically precipitated overnight, took the supernatant, heated and azeotroped for 5 minutes with a heating kettle, that is, heated and kept boiling for 5 minutes, Just can get the safe drinking water that almost does not contain nitrobenzene. At the same time, other organic pollutants, heavy metals, iron and manganese in the water also meet the water quality standards for drinking water.

Abstract

The invention discloses an underground water processing method, which comprises the following steps: adsorbing water through charring rice husk; coagulating; sedimenting; heating to boil; obtaining the product.

Description

technical field [0001] The invention relates to a combined treatment method for underground drinking water, which is mainly aimed at the treatment of groundwater containing trace amounts of nitrobenzene, and belongs to the category of drinking water purification. Background technique [0002] my country's rural population is large and scattered, and well water (ground water) is the main source. The water source is easily polluted by organic substances, and the safety of drinking water is worrying. Especially in the villages and towns along the river basin, organic pollutants in the river water are easy to enter the groundwater during the process of the river water replenishing the groundwater, causing the scattered drinking water along the river to be polluted. At the same time, because the scattered drinking water in villages and towns lacks the processing advantages of centralized water supply, it is difficult to control because of its wide area and many points. Therefore...
