Description
Technical field:
The invention belongs to field of environment engineering technology, be specifically related to a kind of river and gush the recovering method of submerged plant.
Background technology:
The quality of Urban Water Environment is to weigh the important parameter of life of urban resident level.In China, along with improving constantly of the level of urbanization, Urban Water Environment is subject to the impact of urbanization process more and more remarkable.Due to economic fast development, increasing urban pollutant is discharged in city river, causes city river to pollute and increasingly sharpens, and has had a strong impact on Urban Water Environment quality and resident's healthy living.Particularly and economically developed area complicated in the coastal network of waterways, city river generally loses self-purification capacity.Gush in river how effectively to administer ecological functions degeneration, and restorative water ecological environment becomes the large problem of pendulum in face of government, environmental administration, enterprise, expert and scholar already.
At present, interior reconstruction submerged vegetation is gushed in river not yet report.The mode of gushing interior reconstruction submerged vegetation by river is explored river and gushes new way and the new method of improvement, not only has in theory important scientific value, and have great social effect in practice.
Summary of the invention:
The object of this invention is to provide a kind of river and gush the recovering method of submerged plant, utilize the method can promote river to gush the recovery of water ecosystem, the self-purification function of strengthening river water burst body, promotes degrading river water burst matter to take a turn for the better, and shortens river and gushes the improvement cycle.
The present invention is by applying submerged plant as pioneer, gush the suitable submerged plant of middle cultivation in river, and control the various growth conditionss of submerged plant in gush in river, again by suitable management technique, gush interior reconstruction submerged vegetation at degrading river, the submerged vegetation survival rate of rebuilding reaches 60%~70%, thereby has realized object of the present invention.
The recovering method of submerged plant is gushed in river of the present invention, comprises the following steps:
(1), determine place: selecting water transparency is that 0.5~1.2 meter, dissolved oxygen are 8.7~9.2mg/L, pH6~9, NH
3-N0.1~4.1mg/L, total nitrogen (TN) 1.2-5.9mg/L, total phosphorus (TP) 0.1~0.8mg/L, BOD5.3~59.8mg/L, COD
mn9.9~11.9mg/L, COD
crthe recovery of row submerged vegetation is poured in the river of 29.3~42.5mg/L;
(2), cultivating and growing: the healthy plant of selecting submerged plant, its seedling length is 10~15 centimetres, taking 3~5 strains as a Cong Zuowei plantation unit, seedling plantation density is 4~6 clumps every square metre, plantation period is 3~April, cultivation method is that seedling clay is fixed, and Planting pattern is that nature sinks;
(3), settle down and survive: when submerged plant recovery is gushed in river, water area is controlled at 500~5000 square metres, and the depth of water is controlled at 0.5~1.5 meter, current are controlled at 2.0~10.8 centimeters per seconds, water temperature is at 15~20 DEG C, water body illumination 2000~5000LX, and river is gushed substrate and is selected Mud Sediment.
Described submerged plant, is preferably black algae (Hydrilla verticillata).Because the weather hydrologic condition of black algae to region is adaptable, algae is gushed in river inhibitory action, and reproduction speed is fast, is the ideal material that improves river and gush water body environment.
Described black algae, its seedling preferably obtains by the following method: chooses black algae maternal plant in 2~March, is divided into 6~10 centimetres every section, cottage propagation seedling in hydrostatic, normal condition takes root for 5~10 days, and survival rate more than 95%, obtains black algae seedling in batches; The interior available same method of temperature canopy in winter can be bred black algae seedling, and survival rate is more than 95%.
Preferably, when submerged plant growing way in gush in river is vigorous, part salvaging be can carry out, self and the renewal of submerged plant are conducive to.
The present invention gushes by recovering river the local environment that aquatic vegetation is improved river and gushes water ecosystem, recover the 26S Proteasome Structure and Function of the natural ecosystem of rivers system, with low cost, simple and easy to do, low-carbon environment-friendly, benefit are obvious, be applicable to the recovery engineering of the aquatic vegetation of contaminant rivers, be applicable to contaminant rivers Aquatic Plant Diversity and aquatic ecosystem ecological restoration engineering.
