City landscape water body alga-controlling and
Inventor(s): LIJUAN QIU, etal.
The invention relates to a city landscape water body
alga-controlling and pollutant-removing device. In the device of
the invention, the inside of a hexahedron frame is divided into
two spaces along a direction against the current, namely a front
V1 space and a back V2 space, a suspending biological packing ball
with a diameter of 15mm is arranged in the V1 space, and pebbles
with a diameter of 20mm loaded with tetrasilver tetroxide are
arranged in the V2 space. The invention overcomes the separate
defects of the drainage control, sediment release technology, the
manual aeration technology, the bioremediation technology and the
chemical alga-killing technology. The invention integrates the
biological and electrochemical methods to degrade the organic
pollutants in water body and control the growth of alga in water
body so that through the combination action of the biological and
electrochemical methods, alga in water body is hard to grow and
propagate largely while the pollutants are removed; the biological
film on the surface of the suspending biological packing ball
grows to absorb the organic pollutants in water body; and the
pebbles loaded with tetrasilver tetroxide adopts theelectric field
function of the microcell to effectively kill alga microorganisms
in water and inhibit the growth of alga.
The present invention relates to a decontamination device, and
more particularly to an urban landscape water algae control
With the continuous development of China's urbanization, people
are more and more attention to the quality of living environment.
Many urban green space, parks, residential quarters, the
artificial lakes and other water bodies emerging landscape.
But many urban landscape water pollution problems have emerged in
varying degrees, water eutrophication smelly and quite serious,
which not only seriously affect the visual effect of the
surrounding landscape, the loss of landscape water features, but
also people living environment degradation, influence urban
ecological construction, therefore, the landscape water
contaminated governance and repair has become essential.
Prior to the present invention, the existing control water and
organic growth of algae polluting technologies are: control
drainage, sediment release technology, artificial aeration,
bioremediation technology and chemical algae technology.
Defect control drainage, sediment release technology is huge
engineering investment, can not promote the application;
artificial aeration technology is artificial REOXYGENATION
machinery and equipment, improve the dissolved oxygen
concentration, and create conducive conditions for aquatic
ecosystem, but the technology is not only large investment and
need a higher daily operation and management costs, poor
operability; bioremediation technology is a good way, which uses
specific biological pollutants to water absorption, transformation
or degradation, to reduce or eliminate water pollution, restore
biological measures of water ecological function, this technology
can effectively remove some of the water bodies organic matter,
however, this technique can not control water algae; chemical
algae technology, mainly by adding chemicals to kill algae
microorganisms, but not completely, only emergency use, while also
cause secondary pollution.
SUMMARY OF THE INVENTION
The purpose of the present invention is that to overcome the above
drawbacks, design and development of a city landscape water algae
control decontamination devices.
Aspect of the present invention are:
An urban landscape water algae control decontamination unit, its
main technical characteristics that meet within the framework of
the six-sided flow direction divided into two spaces before and
after the V1 and V2, V1 built-diameter suspension biological
packing ball, V2 built-diameter carrier tetroxide four silver
Advantages and effects of the present invention is that at an
appropriate density of the device is mounted, suspended biological
filler ball through the surface of the biofilm growth, adsorption
degradation of organic pollutants in water; tetroxide four silver
pebbles contained through micro-battery electric field,
effectively killing destroy algae microbes, inhibit algae growth
and reduce water chlorophyll a concentration, so as to achieve the
effect of water purification decontamination of algae control.
The device enables the chlorophyll a decreased level of 60-80%,
which controls the water concentration in algae growth, thereby
maintaining the landscape effect of water bodies; at the same time
can remove organic contaminants (measured as COD) by more than
The device consumes no power, no pharmaceutical consumption, is an
environmentally friendly, ecological algae control decontamination
The present invention uses biological, electrochemical methods
integrated Degradation of organic pollutants and inhibit the
growth of algae in the water, through the combined effects of
biological, electrochemical methods, in removing contaminants, it
also makes a lot of hard water algae growth and reproduction to
achieve the landscape water quality improvement and a good
With respect to the existing drainage control, sediment release
technology, artificial aeration, bioremediation technology and
chemical algae technology, the present invention pertains to an
ecological, environmental technology, the innovation is the use of
biological methods and electrochemical methods integrated,
non-power consumption and chemical consumption, but also bring
The device can be long-term improvement of landscape water quality
and good subjective feelings, which is the prior art are difficult
Other advantages and effects of the present invention will
continue to be described below.
Showing the structure of the present invention 1-- schematic
Figure 1 is a sectional view of FIG. 2--.
Figure 1, Figure 2:
Stainless steel tubes welded into cubes frame 1 (according to the
actual landscape water, can be any size), the framework for
external aperture hexahedron 5mm stainless steel mesh 2 full
package; within the framework of a welcome direction of flow
divided into before and after the V1 and V2 two spaces, volume
ratio of 4:1; V1 Built-in diameter 15mm suspension biological
packing balls 3, fill, V2 built a diameter of about 20mm load
tetroxide four silver pebbles 4, filled.
Specific application process of the present invention is
The present invention is installed in a landscape water algae to
be controlled, according to the degree of eutrophication, water
flow may have different installation density of water according to
the order after the first V1 V2 through both space; means the
direction of flow length is generally welcome 1000mm; width of the
device is determined based on the width of the positive side,
there may be a number of modules; height of the device below the
depth of about 200mm.
A landscape river width 9m, depth 2m, subject to eutrophication of
water bodies influence each year from May to October period to
adjust the water every two weeks, otherwise serious breeding
algae, foul smell.
The present invention is applied to the landscape water that
produced wide 9m, height 1.8m control algae decontamination device
(by the four modules), installed in 200mm under the river water
about; when the water flow over, first into V1, then enter V2,
therefore organic pollutants in water obtained in V1 was more
fully biodegradable, water is part of the ammonia nitrification
and denitrification, the removal of water played a role of organic
pollutants and ammonia; then water into the V2, due to the load
tetroxide four silver cobblestone micro-cell electric field of
algae (a characterized by chlorophyll) most were killed.
V1, V2 result of the combined effects of the water to improve
water quality significantly improved sensory effects.
The present invention is first suspended biological filler ball
bioremediation, after silver tetroxide four silver cobblestone
During the first three days, chlorophyll a decreased by 40
percent, 7 days fell by 60%, to the first 30 days, the chlorophyll
concentration in the water body is 15 percent installations before
water algae growth is controlled at a very low level; and , the
first 30 days, the concentration of organic pollutants in the
water body (COD) decreased significantly, the original 50%; the
first 30 days, water transparency of 0.4m, significantly improved
water landscape effect.
