Description
Technical field
The present invention relates to a kind of active biological film for removing river, lake pollutent and preparation method thereof and use, be used for the reparation of river, lake original position, say more specifically a kind of biological renovation method that utilizes the active biological film that adheres on the biofilm carrier of new texture and material to remove pollutent in the river, lake.
Background technology
At present, the measure of the Water quality restoration such as river, lake mainly contains desilting, changes water, chemical agent, adds microbiological water purification agent, planting aquatic plants etc.Desilting, change water, chemical agent, these measures and can only improve in a short time water quality, can not fundamentally repair the ecosystem, and the long-time maintenance water quality.Although planting aquatic plants can absorb the pollutent in water body and be beneficial to the recovery of the ecosystem, but the seasonal death of plant can bring secondary pollution, make the alluvial of river, lake, make even in a short time water quality deterioration, may cause the Vulnerable Ecosystem that wawter bloom destruction has just been set up.And microorganism has the pollutent in decomposition and inversion water as the decomposer in the ecosystem, promotes the ability of the material cycle such as C, N, P.Add the self-purification capacity that microbiological water purification agent can improve water body, eliminate the disadvantageous effect that plant death brings.But due to complexity and the impact of various unfavorable factor of water surrounding, can reduce the quantity of the water purification microorganism that adds rear water body, finally affect the self-purification capacity after water body recovers.Therefore, how improving effective quantity and the survival time of water purification microorganism in water is an essential condition that affects the microbiobacterial agent result of use.
For the better effect of performance water purification microorganism, the bio-carrier of similar artificial aquatic weed has appearred.These carriers are that the fiber of chemosynthesis is processed through specific, and it is easy to by microorganic adhesion.With these artificial aquatic weed field planting and lakebed, utilize the microorganism in natural enrichment water body on carrier, make it reach the purpose that purifies water.But the water purification ability of the indigenous microorganism that adheres on the artificial aquatic weed of this natural enriched microorganism does not have the microorganism water purification ability of particular screen strong, and on artificial aquatic weed, the film formation time of indigenous microorganism is long, generally needs the 3-6 month.So, general competence exertion purifying water effect after these artificial aquatic weed field planting a very long times.
How can form fast microbial film, and it is used in lake treatment, to have become the key that affects the water purification microbial process.
Summary of the invention
The object of the invention is to, overcome the deficiency that prior art exists, provide that a kind of specific surface area is large, the material simple and durable, can freely swing, long service life, cost are low, can adhere to fast the water purification microorganism and utilize a kind of active biological film and preparation method thereof of its high-efficient purification water quality and use.
The technical scheme of a kind of active biological film for removing river, lake pollutent of the present invention is: it comprises buoyancy aid, carrier and weighted; Described carrier is become by some sub-vehicle group, and every sub-carrier top is connected with a buoyancy aid respectively, the bottom be side by side one whole or connect successively after become an integral body or be fixedly connected with weighted; With vertical fixedly connected forming, after every sub-carrier freely launches, its transverse section is multidirectional radiation to described sub-carrier by several soft long bands; Described weighted is a mass and be horizontally placed on water-bed long bag or from as the mass that can be fixedly connected with the carrier bottom of packing into; The height of sub-carrier and weighted transverse width sum are less than water depth.
Further technical scheme is on the basis of technique scheme:
Described active biological film, its every sub-carrier by 4 soft long bands with vertical fixedly connected forming on one side, or by two long bands of wide softness longitudinally therefrom suturing with thread management form; After every sub-carrier freely launches, its transverse section is the radiation of four directions to " * " shape.
Described active biological film has the connection cord that is connected with adjacent active biological film on its carrier bottom or weighted.
