Background technology

At present except the large, medium and small city that has rivers to flow through be draw rivers water after purified treatment as the townsfolk drinking water source, the city that many no rivers are flowed through, especially the city of dry area in north china, and numerous residents from villages and towns all are used as the drinking water source with reservoir or other reservoirs, and the concrete practice is the retaining in the reservoir (or pond) to be inserted through pipeline form drinkable tap water after water factory carries out purified treatment and insert huge numbers of families again.Because earth surface has the abundant iron content and the oxide of other metallic elements, the different differences of different regions water body quality that also caused with the content that contains various metal oxides of different region iron content are very big, because the sand in the mountain region, metal such as earth and iron can dissolve in the rainwater in the infiltration and flow into reservoir or reservoir among, though wherein the water of sandy soil just can be clarified through 10 to 20 days stationary stream precipitation, but the only few part of contained iron and various metal oxide and various organic matter is deposited among the native Barren of bottom of the reservior in the water, but the overwhelming majority can dissolve for a long time and be mingled in the water body by their concentration content of level distribution, promptly dark more amount of metal concentration high more (can be described as " metal sewage ") such as water layer iron content, the content of dried up near more water layer iron content and other metals is few more (concentration is low more) just, at above-mentioned situation, the administrative staff of Running-water Company take the water inlet of tap water water intake conduit in the storehouse, dam is raised mostly, so that obtain the water source from high water level, this measure can only solve temporary transient problem, can't solve essential problem, because reservoir (or reservoir) upland water is continuous, come also to bring continually in the water with in the past with " the metal sewage " of equal size, only by improving the water inlet water level of water intake conduit, though containing filth amount is less than the containing filth amount of upland water in the water source of being got, but can not block the continuous increase of containing filth amount in the water body in the storehouse, in the near future, " metal sewage " water layer of high concentration is increased to the water level place of intake pipe water inlet again, these " metal sewage " are though to handle through water factory also be to be difficult to remove, when the user drinks these tap water, iron rust fishy smell (water body also can yellowing) in the sun, is arranged often unavoidably.

Summary of the invention

The purpose of this invention is to provide a kind of as the reservoir of drinking water source or the pollution absorption and drainage method and the pollution absorption and drainage apparatus (device) in pond, make and help greatly reducing reservoir " metal sewage " concentration, improve reservoir water quality, alleviate the purification cost of removing contamination of water factory, improve the cleanliness factor of resident's drinking water.

Pollution absorption and drainage method of the present invention is realized with following technical scheme: this method step comprises: select suitable water surface area (as greater than 100m in reservoir or the most low-lying place of basin bottom ²) be exclusively used in water body waters to be removed contamination through cleaning out a conduct after the clear stasis of blood, at the bottom of reservoir dam, be preset with blowdown main (or sewage pipe) in addition, blowdown main is provided with some water inlets as sewage discharge tube and they are extended to the water body that is rich in metal sewage with the bottom in this waters to be removed contamination be connected, to discharge the high water body (can be used as agricultural irrigation water) of metal concentration such as iron content.

Reservoir of the present invention or pond precipitation are inhaled (dirt) sewage disposal facility and are comprised: 1. opened up one greater than 100m through being chosen in the most low-lying place of reservoir or basin bottom through after the clear stasis of blood ²The special use water body waters to be removed contamination of suitable water surface area.2. be equipped with sewage pipe or house steward at the bottom of the reservoir dam or at the bottom of the pond, pond, this sewage pipe or house steward are provided with at least more than one water inlet as sewage discharge tube and be extended to the water body that is rich in metal sewage with bottom, this waters to be removed contamination and be connected.

The present invention's above-mentioned technical scheme when implementing also can further be specially:

One, described sewage pipe or house steward's water inlet is the waterline height H that the waterline height h at sewage discharge tube place should be lower than the water inlet of tap water water-supply-pipe.

Two, described sewage pipe or house steward's delivery port is that sewage draining exit can be connected with the drain off floodwaters water inlet of preparation pipe of reservoir, but the waterline height of this water inlet should be lower than the height (accompanying drawing slightly) of the actual water level line in the reservoir.

Compared with the prior art, use the inventive method and facility smoothly " metal sewage " in reservoir or the reservoir to be discharged outside the storehouse, thereby the concentration of metal oxide such as iron in the favourable very big reduction water, can improve drinking water quality at all, also greatly alleviated simultaneously the cost that water factory (or user) removes contamination and purifies, generally can reduce water factory and reach amount more than 1/3rd with aluminum sulfate and calcium oxychloride ton ratio as purifying water body, iron rust fishy smell also has been gone for ever, and the user begs for vexatious iron rust oxidation flavescence look water most and disappears.

Description of drawings

Fig. 1 is provided in a side of the structural representation of the soil pick-up blowdown purifying type facility (device) in the reservoir.Wherein: 1～reservoir surface water body, 2～dykes and dams (dam, storehouse), the 3～water body waters of waiting to remove contamination, 4～sewage pipe (or blowdown main), 5～blow-off pipe water inlet (sewage discharge tube), 6～tap water water-supply-pipe, 7～post precipitation are rich in the water body of metal sewage such as iron.

The specific embodiment

With reference to Fig. 1, the present invention is 20～300,000 m with a storage capacity ³Reservoir be example, the most low-lying place, reservoir bottom hews out an area and reaches the water body waters that 200～300 square metres waters conduct waits to remove contamination usefulness after the clear stasis of blood, the depth controlled in this waters is built in the degree that does not threaten dam, storehouse safety, a default sewage pipe (house steward) at the bottom of the dam, caliber is chosen in 10～20cm, and the water inlet of sewage pipe is that sewage discharge tube extends to bottom, water body waters to be removed contamination and is connected with the water body that is rich in metal sewage.The water inlet waterline height of blow-off pipe should be lower than the waterline height of tap water water-supply-pipe water inlet.When using the bigger reservoir of storage capacity to do the tap water water source, can further strengthen the blow-off pipe caliber, and can increase a plurality of sewage discharge tubes and communicate with house steward.Blowdown main also can be installed side by side with the tap water water-supply-pipe, but the high concentration of its discharge " metal sewage " only is applied to the agricultural irrigation purposes.Under special circumstances, the delivery port of sewage pipe can be connected with the water inlet for preparing pipe that drains off floodwaters of reservoir, and prepare pipe by drainning off floodwaters and carry out the soil pick-up blowdown, or also can discharge outside the storehouse or reservoir outer (figure slightly) with " metal sewage " in the blow-off pipe by the pump that draws water that is located at dam crest portion.The water body waters of opening up a plurality of usefulness of waiting to remove contamination of big or reservoir bottom configuration complexity when reservoir capacity, and more installation soil pick-up arms are as sewage discharge tube arm and these water body waters be connected (accompanying drawing summary) of waiting to remove contamination.
