Description
Technical field
The present invention relates to a kind of to the heavy metal in paddy field, pond and these water bodys of wetland, device that organism carries out adsorption cleaning processing.
Background technology
Be accompanied by the development of industry, mining industry, communications, agricultural, the situation of environmental pollution is more and more severe, heavy metal contamination is typical case particularly, heavy metal causes pollution in various degree to soil, atmosphere, water body, all kinds of animals and plants gather heavy metal in the mankind's body of food chain top by the amplification of biologic chain, and human body is caused to great harm.Thereby heavy metal contamination remains in the fields such as environment, food, health detection and be subject to widely paying close attention to, according to statistics, over nearly 5 years, the rising of heavy metal has caused tens of colonies event, as: blood lead event, mercury poisoning event, the rice cadmium event etc. that exceeds standard.As can be seen here, heavy metal contamination has become Social Events.To this, all dropped into substantial contribution and manpower both at home and abroad and carried out development and application subduction pollutent (heavy metal, organism etc.) residual content new technology.Developed during this time numerous treatment processs, comprise activated sludge process, change water law, soil replacement method, landfill method, biological restoration etc., but there is certain drawback in large multi-method: activated sludge process operating procedure is complicated, and the cultivation of active sludge has certain difficulty: change water law and soil replacement method engineering is too great, invest higher; Landfill method is not thoroughly processed pollutent, but by pollution transportation, does not meet the demand for development of environmental friendliness society; Biological restoration is consuming time longer, and efficiency is on the low side.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of device that heavy metal in the water body in paddy field, pond is carried out to adsorption cleaning.
Solve the problems of the technologies described above and adopt following technical scheme: this paddy field, pond heavy metal adsorption device, comprise treating pond, adsorbent and magnetic recovery device three parts, two offsides for the treatment of pond have respectively water inlet pipe, rising pipe, on rising pipe, there are valve and water circulating pump, the water inlet pipe mouth for the treatment of pond is placed in assorted clearly grid, in the water body for the treatment of pond, hang floating adsorbent from above, adsorbent is by the float on top, the absorbent packet that sorbent material is housed in the irony sinker of bottom and centre is combined into one: for reclaiming the magnetic recovery device of adsorbent, be casing or blocks, be placed in and process outside pool side or pond.
At least one of above-mentioned adsorbent, the number of packages of adsorbent is directly proportional to the existing coverage of water for the treatment of pond, and the cumulative volume of absorbent packet is directly proportional to the existing water yield for the treatment of pond, and the absorbent packet height of adsorbent is directly proportional to existing water depth.
Grid is located at treating pond pool wall top, and transverse section is " L " font, and the first half of its vertical portion is for the floating porous plate of foreign material of gear is, the imperforate plate that the Lower Half of vertical portion and horizontal part are the heavy foreign material of gear.
The beneficial effects of the utility model are: the application of magnetic recovery device, can make to be numerously distributed in adsorbent in water body by centralized recovery, and fast save again labour.The adsorption treatment of adsorbent to pollutent, less energy-consumption, low cost.Long strip type absorbent packet on adsorbent has expanded the contact area with sewage, has improved the processing efficiency of pollutent: adsorbent can reuse after cleaning and being dried.

Fig. 2 installs the structural representation of box magnetic recovery device for this.
Embodiment
The utility model is described in further detail below in conjunction with embodiment and with reference to accompanying drawing:
This paddy field, pond heavy metal adsorption device, comprise treating pond 1, adsorbent and magnetic recovery device three parts, two offsides for the treatment of pond have respectively water inlet pipe 3, rising pipe 6, on rising pipe, there are valve 5 and water circulating pump 4, this device is placed in the water inlet pipe mouth for the treatment of pond in assorted clearly grid 2, in the water body for the treatment of pond, hang floating adsorbent from above, adsorbent is combined into one by the absorbent packet 8 that sorbent material is housed in the float 7 on top, the irony sinker 9 of bottom and centre; For reclaiming the magnetic recovery device of adsorbent, be casing 10 or blocks, be placed in and process outside pool side or pond.At least one of above-mentioned adsorbent, the number of packages of adsorbent is directly proportional to the existing coverage of water for the treatment of pond, and the cumulative volume of absorbent packet 8 is directly proportional to the existing water yield for the treatment of pond, and absorbent packet 8 height of adsorbent are directly proportional to existing water depth.Grid 2 is located at treating pond pool wall top, and transverse section is " L " font, and the first half of its vertical portion is for the floating porous plate of foreign material of gear is, the imperforate plate that the Lower Half of vertical portion and horizontal part are the heavy foreign material of gear.The magnetic force of magnetic recovery device 10 is greater than the buoyancy of float 7, the buoyancy of float is greater than the gravity sum of absorbent packet 8 and sinker 9.
When pond water, paddy field, sewage marshy are processed with this device, first close rising pipe valve 5, the high low head of recycling physical features, nature is introduced water in the grid 2 for the treatment of pond, or with water pump extracting to this grid, treating pond water is filled with to fast and is stopped into water completely time.In the consistent long strip type absorbent packet 8 of a plurality of length, pack the sorbent material of gac and so on into again, tighten the central part that ties up to together the float 7 of polyethylene foams matter after sack, also tie up on the slab-shaped sinker 9 that ties up to together irony the lower end of these absorbent packets 8.By tying up like this adsorbent forming, throw more equably to the water body for the treatment of pond 1, start the heavy metal ion in water body to adsorb.If treating pond water depth is substantially equal to adsorbent height and the distribution density of adsorbent in water body is larger, just within 8 hours, complete absorption, be opened to aqueduct valve 5, the water after purifying is put into pond or paddy field.If treating pond water is very dark, absorbent packet compared with short and in pond distribution density little, can start water circulating pump 4, by circulating pipe again extracting, enter treating pond, after repeated multiple times absorption, through 24 hours, shut down to put to purify waste water and return to pond and paddy field.For avoiding the water for the treatment of pond excessively dark, sinker not at the bottom of pond, float is under certain wind, many adsorbents can be scraped to a side pool side, impact is absorption evenly, therefore, the length of absorbent packet should consider that depth of water sets, make sinker can at the bottom of pond, work the fixed action of casting anchor.What Chi Shui was shallow, adsorbent distribution density is large can not close rising pipe valve, is not cycled to repeat absorption, disposable continuous-flow type absorption in treating pond.
While reclaiming these adsorbents, when the distance that treating pond water must be discarded to the water surface and sinker is less than the distance that the magnetic force of magnetic recovery device 10 can reach, box magnetic recovery device is put in to water surface orientation to float, many adsorbents are held to recovery, concentrate and clean, the sewage washing down is done to harmless treatment by environmental requirement, then sorbent material is dried to rear recycling.
Box magnetic recovery device is a kind of electromagnet, and the magnetic recovery device of blocks is a kind of permanent magnet, and it is just recyclable that permanent magnet needn't bleed off the water for the treatment of pond when reclaiming adsorbent.
