Description
Technical field
The present invention relates to the device and method that a kind of cylindricality gac improves river and lake water quality, belong to water-treatment technology field.
Background technology
Along with the development of economy and the quickening of urbanization process, unprocessed or process city domestic sewage not up to standard and trade effluent flow into rivers and lake in a large number, in addition the existence of agricultural area source and city surface source pollution, the nutritive salt such as lake, fluviatic nitrogen, phosphorus are constantly accumulated, causes the eutrophication process accelerated development of water body.The most of lake of China is plain type or plateau type freshwater lake, has occurred eutrophication to some extent.The technological approaches one of lake and reservoir eutrophication control is abatement water pollutant especially nutrient concentrations, increases water body self-purification ability, nutritional profile is reduced to poor nutritional status; Two is the environment breaking the quick growth and breeding of wawter bloom algae, restrains frustule reproduction speed, reduces algae cell density, suppresses frustule to be assembled and wawter bloom generation.Algae needs to manufacture organism by photosynthesis, maintains own growth, breeding.Suitable intensity of illumination and the suitableeest wavelength are the bases of algal bloom.So suitable shading can reduce algae concentration.From the Main Function process of every technology, Physical, chemical method, biological process and synthetic method 4 class can be divided into again.
(1) Physical: utilize the pollutent in physical action separation water body, or built the technological method of algal control environment by physical process, as physical adsorption techniques.
(2) chemical method: utilize the pollution substance in chemical reaction Separation and Recovery water body, or the technological method being created algal control algae removal condition by chemical process, as chemical dephosphorization technology.
(3) biological process: utilize biological metabolism, to make in water body and bed mud in dissolved form, the pollution substance of colloidal is converted into stable innoxious substance, or is created the technological method removing algae condition by bioprocess, as macrophyte planting technology.
(4) synthetic method: utilize physics, chemistry, biological comprehensive action, the pollution substance in dissolved form colloidal and suspension in water body and bed mud is made to be converted into stable innoxious substance, or create the technological method except algae condition, as ecological wetland technology by physics, chemistry and biological combined process.
Though chemical method dephosphorization efficiency by using is higher, because cost is higher, have the possibility of secondary pollution, use is restricted.Biological process at beautifying water body view, purify water, keep, in nutritive equilibrium and the eubiosis, there is significant effect, but in lake, river in winter, waterplant faces and freezes dead possibility, large by water temperature seasonal effect.And lake, synthetic method process river such as ecological wetland technology floor space is large especially, not easily promote the use of.
Summary of the invention
Technical problem to be solved by this invention is, a kind of device using cylindricality gac physical adsorption water pollution thing is provided, this device adsorption area is large, can not cause secondary pollution, be easy to mobile, can not to affect boat current and to be stuck in He Hu corner and planktonic organism can depend on its growth, be convenient to later stage salvage processing, add and greatly reduce light application time, therefore inhibit the growth of algae to a certain extent; Further, the invention provides the device that a kind of floor space is little, adsorption area is large use cylindricality gac improves river and lake water quality; Further, the invention provides a kind of method using cylindricality gac physical adsorption water pollution thing.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of cylindricality gac improves the device of river and lake water quality, it is characterized in that: comprising: hollow cylindricality gac, some static lines are parallel successively after penetrating some described cylindricality gacs is fixed on circle ring rack and the conglobate gac face of shape, described circle ring rack is fixed with counterweight and some suspension balls.
Described static line comprises the rope made of hemp.
Described circle ring rack comprises stainless steel annulus.
Described suspension ball is uniformly distributed on described circle ring rack, and the number of described suspension ball is at least 4.
Described counterweight comprises China fir cage, is provided with stone grain in described China fir cage.
Described China fir cage is made up of China fir bar.
The number of plies in described gac face is at least 2 layers, is connected between every layer by described static line.
Described stone grain comprises gravel and/or cobble.
Cylindricality gac improves a method for river and lake water quality, it is characterized in that: comprise the following steps: be through on static line by hollow cylindricality gac and form chain different in size, then is fixed on thick and fast on circle ring rack by described chain and forms gac face; Circle ring rack is evenly distributed with counterweight and some suspension balls; The number of plies in described gac face is at least 1 layer.
Cylindricality gac is through on the rope made of hemp, forms the chain that length is different, then it is fixed on thick and fast on stainless steel annulus, form gac face, put it in pending sewage, utilize the adsorption of cylindricality gac, remove various pollution substance in water.
Gac face is furnished with four suspension balls, gac face can be helped to float on the surface.When in the water in suspension of needs gac face, then realize by counterweight under gac face.If handled sewage pollution material concentration is comparatively large, multiple gac faces rope made of hemp can be fixed, do multilayer gac face, reduce floor space.
Described counterweight is the boxes and baskets that China fir bar is made, and adds gravel inside or cobble is suspended in the water surface to realize gac face according to gac face weight.Counterweight is made up of China fir cage and stone grain, regulates the weight of stone grain to suspend in water to realize gac face according to gac face weight.
Described cylindricality gac is uniform hollow cylindrical gac, namely increases adsorption specific surface area, again easily assembling.
Circle ring rack is annulus, can reduce floor space on the one hand, gac face can be allowed to move more freely on the other hand, does not affect boat and passes through, and is easy to move out from He Hu corner simultaneously.
The invention belongs to physical adsorption techniques.Because of the feature of gac self, this gac face is less by the impact of the water temperature and quality water yield, and material is easy to get, and cost is low, can promote the use of in the four seasons.Suspension ball on gac face ensure that gac face floats on the water surface, utilizes current and wind that gac face is moved, and increases the chance that cylindricality gac contacts with pending material.Circle ring rack is annulus, and one reduces floor space, and two can allow gac face move more freely, does not affect boat and passes through, and is easy to move out from He Hu corner simultaneously.Because this gac face can float in pending water for a long time, planktonic organism can depend on growth, is convenient to later stage salvage processing, adds and greatly reduce light application time, inhibits the growth of algae to a certain extent simultaneously.The method economical and efficient, treatment effect is obvious, and convenient for cleaning and maintenance, has good application value.
A kind of cylindricality gac provided by the invention improves the device and method of river and lake water quality, impact by the water temperature and quality water yield is less, material is easy to get, cost is low, can promote the use of in the four seasons, adsorption area is large, area occupied is little, secondary pollution can not be caused, be easy to mobile, can not to affect boat current and to be stuck in He Hu corner and planktonic organism can depend on its growth, be convenient to later stage salvage processing, add and greatly reduce light application time, therefore suppress algal grown to a certain extent.The method economical and efficient, treatment effect is obvious, and convenient for cleaning and maintenance, has good application value.
