Integrated device for water quality restoration and conservation of polluted surface springs

Abstract

The invention provides a polluted superficial spring water quality restoring and conservation integrated device. The polluted superficial spring water quality restoring and conservation integrated device comprises a water amount adjusting tank used for storing the superficial spring water and a slow filter which is connected with the water amount adjusting tank by virtue of a diversion pipe and isused for slowly filtering and storing the superficial spring water, wherein an overlying water layer, a slow filtering layer, a gravel water storage layer and a clear water chamber are sequentially arranged in the slow filter from top to bottom; a superficial spring in the water amount adjusting tank can flow into the overlying water layer by virtue of the diversion pipe; a filter material formedby mixing brick powder, fine gravels and red clay is arranged in the slow filtering layer, and the average particle size of the fine gravels is 2mm; and the gravel water storage layer simulates an underground water bearing stratum and is full of gravels with the particle size of 8-12mm. The polluted superficial spring water quality restoring and conservation integrated device provided by the invention can be built on the basis of an existing water cellar, investment is low, electric quantity and a medicament do not need to be consumed, disinfection by-products (DBPs) with threat to drinking water safety are not produced, water quality restoring effect is good, the restored water is stored immediately, and secondary deterioration of water quality is completely eradicated.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an integrated device for water quality restoration and conservation of polluted surface springs. Background technique [0002] In some karst mountainous areas, local residents use epikarst springs (referred to as surface springs) as their drinking water sources. Surface springs are easily affected by pollution from domestic waste, agriculture, and aquaculture. Some surface springs have serious microbial indicators, sensory traits, and general chemical indicators that exceed the standard. In addition, the amount of surface spring water changes strongly with the seasons, so local residents have to store water in cellars and water tanks during the wet season for use during the dry season. Due to the unreasonable water storage facilities, the water body is affected by factors such as bird excrement, plant residues, sunlight exposure, etc., the water quality deteriorates, and...
