Description
Technical field
The invention belongs to sewage treatment area, relate to a kind of chemical pollution place underground water sulfite salt and block and restorative procedure.
Background technology
Along with the fast development of industry, a large amount of pollutents flows in water, damages the mankind.Water is the base substance that the mankind depend on for existence, and tellurian drinkable Freshwater resources account for 4.9% of the whole world, and wherein 68% from underground water.But due to the production of industrial chemicals, and some light industry are operational lack of standardization, and the contaminant infiltration causing some poisonous enters in underground water, cause large-scale pollution, therefore protect water source to underground water, be the emphasis of global concern,
Sulphite is a kind of mineral compound, soluble in water, volatile, contact with oxygen in atmosphere and can generate ortho-phosphoric acid, resolve into severe toxicity, explosive material when being heated to 180 DEG C, have strong water absorbability and deliquescence, be corrosive, usually as pesticide intermediate, the toxic action very strong again to human body.This material is once in unprocessed inflow water body, be touched by people or hydrobiont, and consequence, by hardly imaginable, therefore blocks and the effective ways repaired in the urgent need to a kind of chemical pollution place underground water sulfite salt.Some conventional methods have: absorption method, ion exchange method, chemical precipitation method etc., all there is the shortcomings such as the cycle is long, and cost is high, severe reaction conditions in these methods, the open a kind of reaction of the present invention is fast, technique is simple, without the need to regulating pH, and the blocking-up that sludge output is low and the method for repairing chemical pollution place underground water sulfite salt.
Summary of the invention
The invention provides a kind of chemical pollution place underground water sulfite salt to block and restorative procedure, this method reaction is fast, and technique is simple, and without the need to regulating pH, sludge output is low.
