Description

The dmp filter tower
Technical field
The present invention relates to a kind of dmp filter tower.
Background technology
Along with the continuous quickening of urbanization process, environment water water quality constantly descends." China Environmental State Bulletin in 2011 " shows, in the ten large water systems of the whole nation, I～III class water quality section ratio accounts for 61.0%, and IV～V class accounts for 25.3%, and bad V class accounts for 13.7%.Thereby some areas that originally had abundant water resources also are faced with the water quality type lack of water, also have some lack of water cities excessively to tap ground water resources, and face the problems such as ground settlement.The source of a regional water mainly comes from runoff supply and precipitation supply from the hydrological angle.In the Runoff variation, Atmospheric precipitation in today since the atmosphere pollution that pellet and gaseous contaminant cause and can't have to directly being discharged in the environment directly as production, domestic water can not effectively be utilized by people.Abroad, some developed countries have the history of decades for the research of the collection utilization of Rainwater Resources and rainwater, external correlation technique is Engage of standard, industrialization stage, and the domestic research that mainly stresses industrial wastewater and sanitary sewage process aspect, for the processing industry of rainwater and the research of resource aspect seldom, because before the nineties in 20th century, running water is not yet popularized in vast rural area, in the situation that the industrial development of domestic small city falls behind relatively, rain water on roof pollutes little and directly is used as Drinking Water.After this popularize along with tap water pipe network and Process of Urbanization in, the pollution of atmosphere, water when running water has replaced people gradually, the early stage water tower that is used for collecting rainwater of building of some urban residents, mostly fall into disuse, traditional water tower has been lost original function, faces dismounting.Therefore, the rainwater treatment technology product of developing a kind of suitable China's national situation becomes the vital task of promoting a conservation culture in from now on a period of time.Simultaneously, for the resident in some mountain areas, the expenses such as pipe network laying and maintenance are higher, and water quality where is better, and this invention seems more meaningful.
Summary of the invention
The present invention is directed to present shortage to the problem of the special equipment of the Treatment and recovery of rainwater, proposed a kind ofly rainwater to be processed into domestic water, dmp filter tower easy to use.
Dmp filter tower of the present invention is characterized in that: comprise tower body, roof drainage main, the pipeline that catchments, the cat head pipeline that stretches into tower body inside is installed on the top of described tower body, and at the end of described cat head pipeline the first liquid redistributor is installed; The inner chamber setting of described tower body is laid on the first packing layer, the second packing layer on the packing support from top to bottom successively, installs between described the first packing layer and described the second packing layer and twines a filter; On the sidewall of described tower body bottom the tap that is communicated with described tower body inner chamber is set; Described roof drainage main is connected in the drainage collection plate place at eaves place, roof; Describedly catchment that pipeline one end is communicated with described roof drainage main, the other end and described cat head pipeline connection.
The overflow pipe that the setting of tower body sidewall between described packing layer and first liquid distributor is communicated with the tower body inner chamber.
The top of described tower body is provided with the manhole of cover plate.
Described first liquid distributor is the disc structure with 5 spray heads, and a spray head is positioned at the center of circle, and all the other four spray heads are evenly distributed on the circumference of first liquid distributor.
Filler in described the first packing layer is that the filler in organobentonite, described the second packing layer is bamboo charcoal.
The packing support below that described the first packing layer is corresponding arranges the second liquid distributor.
The organobentonite of described the first packing layer is made by microwave process for synthesizing by original soil.
Described bamboo charcoal fire under 700 degree celsius temperature, through the screening after particle diameter be controlled at 0.6-0.9 mm.
The import department of the described pipeline that catchments arranges screen mesh in the stainless steel.
The lower end of described roof drainage main arranges control valve.
When rainwater early declines, as long as open the control valve of roof drainage main lower end, relatively pollute larger first rain and will enter rainwater or drainage system pipe network, be not collected; Manual closed control valve after a period of time, relatively the rainwater of cleaning can enter first liquid redistributor in the tower body by the pipeline that catchments, then rainwater is stored in the tower body bottom successively through behind the first packing layer and the second packing layer, and the tap that only need open the tower body bottom during use gets final product; When entering the excessive rainfall of tower body, unnecessary rainwater can be got rid of from the overflow pipe of tower body; When needing cleaning or maintenance in the tower body, the maintenance personal can enter from the manhole at tower body top tower body inside.
The invention has the beneficial effects as follows: originally do not pay attention to by modern people, relatively preferably Atmospheric precipitation of water quality can be utilized by people, can alleviate to a certain extent the present situation of short water supply.Described dmp filter tower does not consume electric energy, and average operating cost is low, has reduced to a certain extent the expenditure of people's water rates.In addition, described dmp filter tower has solved the characteristics of rainy season to a certain extent, makes the resident can use the area of rainwater, the especially drought of cleaning within the larger time period.
