The biodialysis system

Technical field

The utility model relates to the technical field that water sludge purifies, and relates in particular to a kind of biodialysis system.

Background technology

[0002] along with national in the last few years Economic development, the expansion of many urban construction scale, population increase the increase of various rubbish, discharge excess load, had a strong impact on the city people's quality of life and life security, positive baptism city planning, decision maker's wisdom and ability.

After polluting mud, water, poison ground problems such as the insecticide factory that finds again to remove, fertilizer plant, pharmaceutical factory; , have many message of going into sea, river mouth deteriorating water quality to be reported in succession again, even have serious report of survey to point out that some permeates the ground from the face of land after renovating effect for many years is very little continue three rivers, with serious pollution three lakes, some has been diffused into offshore waters.

Over past ten years, government only just drops into nearly hundred billion yuan in three rivers, three lakes on the one hand; On the other hand, many experts think that also the engineering of administering and technique means are to improve the pollution situation in three rivers, three lakes fully.Can the fact be, produce little effect, even the trend that becomes bad is more arranged.

In China, pollute the processing mode of mud or water, nothing more than two kinds: one, landfill mud, as Shanghai Suzhou River mud at Nanhui Lao Gang landfill; Two, most of city is dehydration, sub-sieve, oven dry or burning, and this method cost height, energy consumption height, secondary pollution are serious.Western developed country was just forbidden landfill mud in 2000, and longer agricultural-food come into the market to sell on the inaccurate landfill piece.

Therefore, how to enrich governing measure, especially all control from sample and set about, a kind of low consumption, carbon-free, low emission, low cost are provided, administer the water sludge method and system sustainably, reaching the effect of long-term stability, is that government and correlation technique department and technician must demand the problem conscientiously studying, think deeply urgently.

Summary of the invention

The utility model purpose, for poisonous soil, pollute mud, sludge water adopts the engineering means, and water is circulated therein, disposes the plant of relative pollutent, gives full play to the biomembranous effect of the flourishing root system of plant, degrade and engulf pollution substance.After being discharged from the face of land, tackled and absorption by the tissue of plant again in water body, thereby it is more abundant, reach the effect of pollution treatment, detoxifcation rapidly, be that a kind of input cost is low, running cost province, low-carbon (LC), low consumption, nothing discharging, sustainable, than the slightly higher leveled pollution treatment technology of bioremediation technology.

For achieving the above object, the utility model provides a kind of biodialysis system, it comprises a treating pond, stretch into one or several water delivery unit in this treating pond, this water delivery unit is provided with one or several water-freeing arrangements that communicate with this water delivery unit, this water-freeing arrangement to treating pond end face direction extend and its on be provided with several water vents along the longitudinal direction, this water delivery unit also is connected to the water supply unit.

Wherein, described " treating pond end face " comprises the surface location after treating pond is filled staying water or mud; " extend " surface location that the water-freeing arrangement that comprises on the water delivery unit that stretches in the treating pond fills behind staying water or the mud to treating pond to treating pond end face direction and extend, namely extend upward or obliquely upward.

Further, this water delivery unit comprises the water injection pipe that is inserted into the treating pond bottom.

Further, this water delivery unit also comprises the horizontal water transport channel that is layed in the treating pond bottom and communicates with water injection pipe.

Further, this water-freeing arrangement is located on this horizontal water transport channel, and direction is extended upward.

Further, this horizontal water transport channel upwards is provided with several posticums.

Further, this water-freeing arrangement surpasses the surperficial 1-100cm of staying water or mud.Preferably, water-freeing arrangement surpasses the surperficial 50cm of staying water or mud.

Further, this water-freeing arrangement is drain board.

Further, this horizontal water transport channel is made up of the drain board of several arranged transverselys.

Further, this biodialysis system also comprises the layer of plants corresponding with purifying all contaminations, and it is located at the top layer of the interior staying water for the treatment of pond or mud.

Further, this layer of plants comprises one or more of reed, cattail, rape, cotton etc.

Further, the sidewall of this treating pond is laid impervious material.Preferably, this impervious material is the antiseepage geotextile.

Further, this horizontal water transport channel upper surface is laid seepage material.Preferably, this seepage material is the infiltration geomembrane.

Further, seepage material is laid on the surface of this drain board.Preferably, this seepage material is the infiltration geomembrane.

Further, this biodialysis system also comprises the secondary-cleaned pond that links to each other by pipeline with this treating pond.

Further, this pipeline is connected to the position, top layer of the interior staying water of this treating pond or mud, plantation pasture and water or breed silver carp in this secondary-cleaned pond.

The utility model is owing to adopt technique scheme, make staying water or mud submergence water-freeing arrangement, as drain board, infiltration through geomembrane on the plate, slowly up by drain board, at this moment, water purification has carried out dilution, washing and fused to all contaminations in staying water or mud, when sewage or mud during through the root of emergent, by the net filtration of its flourishing root system formation, and this flourishing root system net surface can form microbial film when adsorbing a large amount of suspended substances, and degraded and phagolysis by microorganism in the film come the purifying contaminated thing; And the nitrogen in sewage or the mud, phosphorus have promoted the growth of waterplant.When sewage or mud are discharged from the surface, decomposition, conversion, absorption and utilization have been carried out by emergent group's tissue again.

Experimental study shows, when polluted water purifies by reed, can remove the suspended particulate contaminants about 80% in 2-3 days, and the water body that muddiness be can't bear becomes clear rapidly; The enrichment concentration ratio ambient water height of heavy metal contaminants goes out more than 100,000 times in the plant tissue such as reed, cattail.In addition, emergent becomes raw material with nitrogen, the phosphorus of water, carbonic acid gas and dissolving under chlorophyllous photosynthesis, produce organic compound continually, and discharge oxygen.Be consumed in absorption process by its synthetic organic substance part, a part is used for making plant self cell, and every generation 100 gram cells will consume 1 gram phosphorus, 7.29 gram nitrogen and 41 gram carbon in proportion.

So far, pollutent has passed through physics, chemistry, biological three scavenging process in sewage or the mud under the effect of water, and water becomes clear and becomes clean.By biodialysis of the present utility model system, can recover aquatic attitude, recovery and enhancing water body fundamental sum important self-purification capacity and water environment capacity, be the biodialysis system of a kind of energy-conservation, reduction of discharging, low-carbon (LC), sustainable and environmental protection.
