Description
Technical field
The present invention relates to a kind of artificial marsh sewage treatment system, more particularly to a kind of strengthened artificial wet land sewage disposal
The system of effect.
Background technology
At present, artificial swamp is the wetlands ecosystems for simulating a kind of process sewage that natural bioremediation is built, be it is a kind of not
It is disconnected to improve and perfect sewage disposal technology.The general principle of Wastewater Treatment by Constructed Wetlands is：Plant resistance in certain matrix
The strong water purification plant of dirt, when sewage flows through, through a series of physics such as matrix, plant and microorganism, chemistry and biology
Reaction, reduces pollutant levels, discharges after purification of water quality.
Artificial marsh sewage treatment system has been used widely in China.But at present artificial swamp remains one
A little problems are govern the application of artificial swamp：First, the efficiency of Wastewater Treatment by Constructed Wetlands needs further raising, and this is also
The content of vast researcher primary study in the current field；Secondly, artificial swamp matrix has received numerous pollutants,
After a period of time, it receives the ability of pollutant to substantially reduce, and affects the efficiency of Wastewater Treatment by Constructed Wetlands, or even into for people
The endogenous pollution of work wetland, this is artificial swamp significantly reduced key factor of sewage treating efficiency after operation a period of time；
Again, in growth course, absorb the gas synthesis such as nitrogen, carbon dioxide by biochemical processes such as photosynthesis has wetland plant
Machine matter, while the pollutants such as the heavy metal in sewage are also absorbed, after its maturation, if not gathering in, artificial swamp will be become
Endogenous pollution, if mishandling can also cause secondary pollution after harvesting；Finally, after in the winter time wetland plant is withered, its suction
The event resolves of degradation of contaminant are received, the efficiency of wetland variation sewage is also decreased.
With the development of science and technology, scientific research personnel is successfully prepared for efficient absorption using biological material anaerobic pyrolysis
The charcoal of efficiency, its adsorption capacity is 2～3 times of activated carbon.The reparation for being applied to polluted-water solves water pollution
Problem, realizes the recycling of biomass again, and this provides the possibility for solving for above-mentioned artificial swamp problem.But at present still
Have not seen the technology for preferably solving the above problems.
The content of the invention
The invention aims to overcome the shortcomings of above-mentioned background technology, there is provided a kind of strengthened artificial wet land sewage disposal
The system of effect.
In order to realize object above, a kind of system of strengthened artificial wet land wastewater treatment efficiency that the present invention is provided, including
Water inlet system, water inlet charcoal filtering ponds, Wetland Substrate, wetland plant, outlet system and artificial swamp, the charcoal mistake
The activation charcoal is filled with filter tank, the wetland plant is planted on the Wetland Substrate, and the Wetland Substrate is by people
Work Wetland Substrate and activation charcoal composition；
Wherein, the preparation process of the activation charcoal is：
1) the ripe wetland plant is gathered in, is then successively dried the harvested wetland plant and powder
It is broken；
2) the artificial swamp matrix is dried successively and is crushed；
3) by crushing after the wetland plant and the artificial swamp matrix in mass ratio 3～5:1 ratio is fully mixed
Close, obtain mixture；
4) by the mixture, under anoxic conditions high temperature pyrolysis obtain charcoal；
5) charcoal is obtained into the activation charcoal through acid activation.
In such scheme, the particle diameter of the wetland plant and the artificial swamp matrix after crushing is respectively less than 1mm.
In such scheme, the temperature of the high temperature pyrolysis is 400～600 DEG C, and the time is 1～2h.
In such scheme, the charcoal is obtained into concretely comprising the following steps for the activation charcoal through acid activation：Will
The charcoal obtains the activation charcoal with the hydrochloric acid solution and water washing that concentration is 0.5mol/L successively.
In such scheme, the longitudinal section area of the charcoal filtering ponds is the longitudinal section area of the water inlet system
5～30 times, thickness is 0.5～1.0m.
In such scheme, the top of the charcoal filtering ponds is provided with the gap for the impact of anti-high load capacity.
In such scheme, the activation charcoal is shed in the artificial swamp matrix and obtains final product the Wetland Substrate,
Wherein, the activation charcoal in the Wetland Substrate of 0～30cm depths is with the dry weight ratio of the artificial swamp matrix
1:5～20.The Wetland Substrate below 30cm depths does not contain the activation charcoal.When preparing activation charcoal, can be direct
Wetland Substrate in collection artificial swamp, but the 30% of the area of the collection Wetland Substrate no more than gross area every time.
In such scheme, the wetland plant is the strong water purification plant of resistance to soiling, and its harvesting cycle is 1 year.It is described wet
Ground plant concretely reed, canna etc..
In such scheme, the replacement cycle of the activation charcoal in the charcoal filtering ponds is half a year.Replaced
The activation charcoal for changing can again prepare new activation charcoal as raw material.
In such scheme, if the wetland plant quantity in raw material is inadequate, can be with agricultural stalk, feces of livestock and poultry etc.
Debirs replace.
The beneficial effect brought of technical scheme that the present invention is provided is：
1st, activation charcoal is made after by artificial swamp matrix and wetland plant mixing, it is to avoid Wetland Substrate and wet
Ground plant becomes the endogenous pollution of artificial swamp；
2nd, as high-performance sorbing material after acid-wash activation, its absorption property is further enhanced charcoal, and
The soluble pollutants of attachment itself are removed；
3rd, activate charcoal be added to charcoal filtering ponds can preferably filter, adsorb, fixed-contamination thing；
4th, activation charcoal is added in Wetland Substrate can adsorb, fixed-contamination thing；
5th, the system also solve wetland operation a period of time after and winter sewage treating efficiency reduce problem, while
Realize the resource of Wetland Substrate and wetland plant and recycle, also achieve the sustainable operation of artificial swamp.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
In figure, water inlet system 1, charcoal filtering ponds 2, Wetland Substrate 3, wetland plant 4, outlet system 5 activates charcoal
