Abstract
The invention relates to application of a method for cultivating water spinaches on a water surface in controlling sewage, which belongs to the field of engineering ecology studies. The water spinaches with very strong capacity of absorbing nitrogen, phosphonium and the like in a water body are adopted as the main body of an artificial biological floating island; by making use of the buoyant forceof hollow stalks, the water spinaches can float and grow on the water surface without any platforms to avoid the abuses of secondary pollutions to the artificial biological floating island, high manufacturing cost, time and labor wastes and the like, thereby effectively removing the over-high nitrogen and phosphonium concentrations in the water body to achieve the aim of controlling and restoringthe water body eutrophication. An area surrounded by bamboos and any other subjects or fences and the like which can float on the surface of the sewage is convenient for management and beautificationmolding, and the main vines after three times of picking are fished out for composting so as to avoid the secondary pollution to the water body caused by plant decay. The method for cultivating the water spinaches on the water surface can be used for controlling domestic sewage and paper making wastewater.
Description
Technical field
This technology belongs to field of engineering ecology studies
Technical background
Along with the increase of expanding economy and urbanization population, the unprocessed rivers and lakes that directly enter of a large amount of production and sanitary sewage give these water bodys with immense pressure, cause the water quality rapid deterioration.Owing to nutritive substances such as the nitrogen that enters water body, phosphorus constantly increase, the body eutrophication process is accelerated.Utilizing artificial article floating island is the good method of a kind of control and reparation body eutrophication, artificial article floating island directly absorbs nutrition from water body, sewage is carried out in-situ treatment, not other land occupation, the chinampa can adapt to the various depth of waters simultaneously, and management of plant and results also are easier to.Therefore, artificial article floating island is in the research of China with use increasing.The artificial article floating island material mostly is the floating bed of expanded plastic, plant establishment etc., and what have in these floating beds has a secondary pollution, and the cost that has is higher, and what have wastes time and energy, and in order to solve this with problem, has researched and developed the method that the water surface is cultivated mater convolvulus.
Summary of the invention
A kind of water surface is cultivated the improvement sewage method of mater convolvulus
Mater convolvulus claims water spinach again, is convolvulaceae sweet potato genus herbaceous plant.Water spinach originates in area of heavy rainfull, China subtropics, and plantation is all arranged at present throughout the country, and water spinach happiness rich water especially can absorb and utilize a large amount of nitrogen and phosphorus, thereby reaches the purpose that solves body eutrophication.Through experiment, successfully set up the water surface of administering sewage and cultivated the mater convolvulus method.
1) directly gets the climing mater convolvulus that reaches more than 10 centimetres of master that sell in market, remove whole blades, stay petiole, drop into water body and directly cultivate.
2) surround a localized area with any object that can swim in the water surface such as bamboo or with net etc., in order to avoid cause the mater convolvulus excessive multiplication, with rope floating matters such as bamboo are fixed, directly with in the climing sewage of putting into the localized area of mater convolvulus master, mater convolvulus can swim in the zone that surrounds by self buoyancy.
3) mater convolvulus big, vigorous perennial root of formation dish gradually in sewage, mater convolvulus can swim on the water surface and grow because empty stem has buoyancy.
4) treat that mater convolvulus grows the water surface more than 15 centimetres the time, pluck this part mater convolvulus, stipes encumbrance 2～3 joints are removed whole blades, stay petiole, continue to put in the sewage and cultivate.
5) salvage out and carry out compost through plucking the main climing parts in back for 3 times, adopt this type of rearing later on always.
Embodiment
1. it is climing to remove the mater convolvulus master who removes whole blades, put into the zone that surrounds with any objects that can swim in the sewage surface such as bamboos, mater convolvulus big, vigorous perennial root of formation dish gradually in sewage, the buoyancy by self empty stem swims on the water surface and grows.Treat that mater convolvulus grows the water surface more than 15 centimetres the time, keep 2～3 stipes and pluck the top mater convolvulus, the mater convolvulus of plucking is removed whole blades, continue to put in the sewage and cultivate, salvage out and advance heart dish and remove whole blades through plucking the main climing part in back for 3 times, continue to put in the sewage and cultivate, main climing part is salvaged out and is carried out compost after plucking through 3 times, avoids the rotten secondary pollution that water body is caused of excessive multiplication and plant.
Claims (4)
1. the improvement sewage method that the water surface is cultivated mater convolvulus is characterized in that: do not adopt any carrier to cultivate mater convolvulus on the water surface in the zone that limits, administer eutrophication water.
2. the water surface that requires according to right 1 is cultivated the mater convolvulus method, not needing it is characterized in that mater convolvulus is planted on the platform of any chinampa, grows at the water surface by self buoyancy.
3. the water surface that requires according to right 1 is cultivated the mater convolvulus method, it is characterized in that carrying out the mater convolvulus water surface with the zone that floatability object such as bamboo or fence etc. surround cultivates.
4. the water surface that requires according to right 1 is cultivated the mater convolvulus method, it is characterized in that comprising sanitary sewage, culturing eutrophic water and paper waste with the eutrophication water that this method is handled.
