Description

Arid area garden ground rainwater collection processing system implementing and method
Technical field
The invention belongs to rainwater utilization technology field, more particularly to a kind of arid area garden ground rainwater collection processing system System and method.
Background technology
Drinking water is Source of life, and existence is originally.Many remote water-deficient areas in the world, rainwater is the master of local resident Want drinking water source.By taking China as an example, in some remote districts such as northwest of China, by Levels of Social Economic Development and water resource The impact of shortage etc., it is for collecting rainwater that rainwater becomes the engineerings such as the drinking water source of local resident, rain-water pit and water storage pond Key facility, if " 121 project of rain water collection " in Gansu, " the kiln cellar for storing things agricultural " of plateau area of Southern Ningxia, and " the 112 of the Inner Mongol Rain collecting and water saving engineering irrigation ".China also promulgates《Rainwater harvesting engineering legislation》(SL267-2001), this specification Defined rainwater elder generation Jing setting pots remove the particles such as silt therein, subsequently into rain-water pit.The appearance of this specification is significantly Promote the standardization construction of rainwater utilization project.
But existing research shows, for a rainfall, the initial stage, several millimeters of rainwater runoff pollution was the most serious, All contaminants entrained in runoff are almost concentrated, wherein Organic substance, nitrogen phosphorus, pathogen, heavy metal, oil may be contained The pollutant such as class, float.Rainwater, only through simple precipitation process, can only remove mud therein before into rain-water pit The float such as sand, but to dissolubility pollutant poor removal effect therein, it is poor so as to cause to collect rainwater matter, can be to drink The healthy of user works the mischief.Meanwhile, existing specification and Practical Project often only focus on the collection of rainwater, but but The process to rainwater is have ignored, even if the method for collecting rainwater using sub-prime, in cleaning rainwater or inevitably containing dirt Dye thing, only effectively removes pollutant therein, can just obtain qualified drinking water, ensures the safety of water user.
The content of the invention

The collection of arid area garden ground rainwater collection processing system implementing processes processing method, comprises the following steps:
(1), mounting arrangements fixed installation:Be in garden roof and ground correct position be respectively arranged installation ground rain Water collection port, ground rainwater collecting pipe, ground early-stage rainwater collecting pit, cleaning rainwater collection pool, coagulative precipitation tank and filter tank;
(2), rainwater-collecting:The early-stage rainwater for falling earthward is pooled to after ground rainwater collection port, sequentially passes through ground rainwater receipts Collector, the lower port of ground rainwater tee T and ground rainwater perforation floral tube imports ground early-stage rainwater collecting pit, with landing ground The rising of the water surface in early-stage rainwater collecting pit, the ground rainwater rubber ball float in ground rainwater perforation floral tube also rises, and works as ground Water level reaches preset water level in early-stage rainwater collecting pit, i.e., when the water surface reaches ground rainwater spacing orifice plate, ground rainwater rubber Ball float blocks the endoporus of the spacing orifice plate of ground rainwater in the presence of buoyancy, and rainy early stage this period is equivalent to roof Surface is cleaned;Cleaning rainwater rainy afterwards then flows out from the upper port of tee T, and Jing ground clear water manifold enters cleaning Rainwater collection pool;
(3), take cleaning rainwater stirring precipitation:It is artificial to be added to coagulation from a certain amount of cleaning rainwater of cleaning rainwater collection pool taking-up In sedimentation tank, a certain amount of Alumen water purification agent is added, rotate crank, drive shaft and stirring paddle to rotate, first quick stirring 50- 80s, then low rate mixing 4-6 minutes, after stirring is finished, detachable crank is removed, the quiet heavy 20- of the water in coagulative precipitation tank 40 minutes;
(4), clear water filter:The clear water opened on the water surface that drip pan swims in coagulative precipitation tank on clear water discharge pipe is discharged Valve, water is flowed in drip pan by breach of intaking, then enters into clear water discharge pipe by flexible pipe, using pouring filter tank into after container water receiving It is interior, the surface of quartzy sand filter blanket is uniformly distributed in after water-locator, by the filtration and the suction of active carbon layer of quartzy sand filter blanket Attached effect, the float further gone in eliminating water and Organic substance etc., the water Jing water purification outlet pipe after Filtration Adsorption is discharged, and is collected By scalding as drinking water.
At set intervals, it is right in ground early-stage rainwater collecting pit and cleaning rainwater collection pool to go down to enter into by manhole Internal precipitation is cleared up;The blowoff valve opened on blow-off pipe is cleared up the precipitate of coagulative precipitation tank bottom, due to Sedimentation tank body bottom portion can so make precipitate be pooled to blow-off pipe discharge in the low part pyramid like configuration in outside high center;Work as filter When bed of material blocking, filter capacity decline, the edge for carrying filter screen integrally takes out filter material layer, fills again after cleaning to filtrate Fill out.
Using above-mentioned technical proposal, the rainwater in the early-stage rainwater collecting pit of ground in the present invention as sweep the courtyard with it is green Change irrigation to use, clean the rainwater in rainwater collection pool as drinking water source.Further, since the content of organics pole in rainwater It is low, therefore be finally prepared into the drinking water for coming and do not set sterilization process.But, standing time is long, and water quality still can degenerate.Due to making For raw water cleaner middle and late stage rainwater storage cleaning rainwater collection pool in, drinking water can be prepared at any time, it is not necessary to one Secondary property prepares excessive.
Deficiency of the present invention for the existing rainwater-collecting technique in arid area, it is proposed that the method that rainwater separating is collected, will The rainwater separate collection that the serious rainwater of precontamination and middle and late stage are more cleaned, is reduced as far as to as drinking water source portion The pollution level of the rainwater for dividing.The present invention processes the pollutant that can be gone to greatest extent in eliminating water by carrying out to rainwater, obtains To the drinking water of better quality, it is ensured that the health of drinking person.
The present invention realizes that initial stage contaminated serious early-stage rainwater and middle and late stage clean the separation of rainwater, by pollutant load Higher early-stage rainwater is enclosed in early-stage rainwater pond, and used as green area irrigation, road is swept etc. uses water;Rainwater is cleaned to middle and late stage Further after intensive treatment, drinking water is made.Present invention achieves the recycling of rainwater, is to solve drought and water-scarce area People and animals' domestic water problem, there is provided a kind of new thinking and method.
