Abstract
The invention relates to a method of eliminating algae from eutrophic scenic water with high salt content, which is an in situ treatment technology for eliminating algae from water body with high salt content by the optimal combination of surface flow artificial wetland technology and biological grate technology. The treating process can reduce chlorophyll a content from about 400 mug/L to about 10 mug/L and eliminate most of the trophic salts in the water body. The present invention has low system maintenance cost, zero power consumption and no selectivity on eliminated algae, and is especially suitable for eliminating algae from eutrophic scenic water with high salt content.
Description
Technical field
The present invention relates to the method that high saliferous eutrophic landscape water body removes algae.Particularly, be algae in the high saliferous landscape water body of a kind of effective removal, control algal grown, and keep the algae CONTROL PROCESS system of the integrated eutrophic landscape water body of the optimum combination of the artificial swamp of water quality of landscape water and biological grid for a long time.
Background technology
Eutrophication is the obstacle of reuse water as recreational, ornamental artificial water function maximum, also is the problem that landscape water body occurs easily, so after eutrophication appears in landscape water body, removes algae and then become the problem of confronting.Can make the transparency of water body increase the landscape function of landscape restoration water body because remove algae; The removal of algae can help landscape water body to be transformed towards the clear water stable state by the muddy water stable state, thereby strengthens self purification of water body function, the ecological functions of landscape restoration water body.The present invention just is aimed at high saliferous landscape water body and removes the algae problem, and artificial swamp and biological gate technique are carried out integrated a kind of high saliferous landscape water body water algae-removing technology system.
Consult domestic and foreign literature, the present invention does not appear in the newspapers.
Summary of the invention
Purpose of the present invention: the algae-removing method that is to provide a kind of high saliferous eutrophic landscape water body.It is to adopt artificial swamp and biological gate technique to carry out integrated a kind of algae optimum combination technology and highly integrated treatment system removed, can make high saliferous eutrophic landscape water body quality recovery, strengthen the ecological functions of self purification of water body function and landscape restoration water body, thereby the eutrophication in the elimination water solves the algae problem of removing of high saliferous landscape water body.
For achieving the above object, technical scheme of the present invention is: adopt artificial swamp and biological gate technique to be optimized integrated a kind of algae combined process system of removing, its main treating processes is as follows:
(1) earlier landscape water being entered the surface current artificial wetland who makes up with cattail, Canna generalis Bailey, Herba Potamogetonis Pectinati and Herba Caricis Phacotae in Landscape River handles.Artificial swamp is the end with the rubble, and metalling thickness is 10cm, and the plantation density of each kind of plant is: Canna generalis Bailey and cattail 30cm * 30cm/ strain, and Herba Caricis Phacotae 30cm * 30cm/ restraints (2～4 of every bundles), Herba Potamogetonis Pectinati 5g/L meter, hydraulic detention time is 5～10d.After surface current artificial wetland's processing, most suspended substances particle, BOD
5, CODcr, TP etc. are effectively removed.
(2) enter processing in the biological grid again through the water outlet after the artificial swamp processing.Setting up biological grid filler in the biological grid, is skeleton with the stainless steel frame, and biological grid are fixed in up and down on the skeleton, and the application quantity of biological grid is 12cm/L, and hydraulic detention time is 3～10d.After biological grid processing, BOD
5, CODcr, TP etc. are effectively removed by biology.
Beneficial effect of the present invention:
1) content of handling chlorophyll a in the water body of front and back is reduced to 9.2ug/L from about 400ug/L, and nutritive salt also has removal largely in the water body;
2) system maintenance expense is lower, does not need energy consumption, does not have selectivity for the removal of algae.
Embodiment
Below by example the present invention is further described.
Example 1
Framework artificial swamp and biological gate technique integrated system as stated above in the Landscape River of a high saliferous eutrophic landscape water body water.The Landscape River quality of river water is: TN 13.01mg/L, TP 0.66mg/L, NO
3 --N 10.94mg/L, NH
4 +-N 0.30mg/L, titanium pigment 0.10mg/L, COD
Mn11.79mg/L, total mineralization 5569mg/L, algae is based on blue-green algae and green alga.After artificial swamp and the processing of biological gate technique integrated system, the concentration of water outlet chlorophyll a is reduced to 10.5ug/L, has effectively improved the transparency of water body, has reduced the content of nutritive salt in the water body.
Example 2
Framework artificial swamp and biological gate technique integrated system as stated above in the Landscape River of a high saliferous eutrophic landscape water body water.The Landscape River quality of river water is: TN 17.8mg/L, TP 0.93mg/L, NO
3 --N 11.45mg/L, NH
4 +-N 0.56mg/L, titanium pigment 0.19mg/L, COD
Mn13.4mg/L, total mineralization 7761mg/L, algae is based on blue-green algae and green alga.After artificial swamp and the processing of biological gate technique integrated system, the concentration of water outlet chlorophyll a is reduced to 11.4ug/L, has effectively improved the transparency of water body, has reduced the content of nutritive salt in the water body.
Claims (1)
1. the method for controlling algae of a high saliferous eutrophic landscape water body, it is characterized in that: the algae CONTROL PROCESS of the eutrophic landscape water body that the optimum combination of employing artificial swamp and biological grid is integrated, high saliferous eutrophication landscape water is handled through artificial swamp earlier, handles through biological grid again; In the Landscape River of high saliferous eutrophication landscape water, make up artificial swamp with cattail, Canna generalis Bailey, Herba Potamogetonis Pectinati and Herba Caricis Phacotae; Artificial swamp is the end with the rubble, and metalling thickness is 10cm, and the plantation density of each kind of plant is: Canna generalis Bailey and cattail 30cm * 30cm/ strain, Herba Caricis Phacotae 30cm * 30cm/ bundle, 2～4 of every bundles, Herba Potamogetonis Pectinati 5g/L meter; The artificial swamp that makes up is a surface current, and hydraulic detention time is 5～10d; Set up biological grid filler behind artificial swamp, biological grid are skeleton with the stainless steel frame, and biological grid are fixed in up and down on the skeleton, and the application quantity of biological grid is 12cm/L; The hydraulic detention time of biological grid is 3～10d.
