Abstract
The invention provides an adsorption-artificial wetland combined treatment system for strengthening treatment of sewage containing fluorine and arsenic; the system is composed of an adsorption device and an artificial wetland treatment device which are connected in order. The adsorption device is composed of a water inlet system, an adsorption packing layer and a water outlet system, the water inlet system allows water to be introduced from the lower layer, and the sewage is adsorbed by an adsorption packing and then is discharged from the upper layer water outlet system; the artificial wetland treatment device comprises an upper-layer wetland, a lower-layer wetland, a water inlet system and an effluent collection system, the upper layer of the water inlet system is used for distributing water, the sewage passes through the upper-layer wetland and the lower-layer wetland and then is discharged out of the device by the effluent collection system. With adsorption-artificial wetland combined treatment, the life of the artificial wetland can be prolonged. The system has the advantages of small occupation area and good removal effect on fluorine and arsenic.
Description
Technical field
The present invention relates to the materialization-artificial wetland combination treatment process of a kind of intensive treatment fluorine and arsenic polluted water, belong to environment protection and water-treatment technology field.
Background technology
In recent years, flourish along with industrial or agricultural and the industry such as mining, metallurgy, has increased the weight of the pollution of water resources to a certain extent.The content severe overweight of fluorine and arsenic in a lot of local ground watering of China and surface water.While meeting mankind's water, fatal harm has also been brought containing the fluorine of high density and the water of arsenic, long-standing problem people, in order to life and health and the safety of mankind itself, efficient economy must be developed and the tap water of environmental protection and trade effluent remove fluorine arsenic removal process.
Absorption method is a kind of simple water technology, is generally applicable to the sewage that treatment capacity is large, concentration is lower.Absorption method is one of main method removing fluorine and arsenic at present.Absorption method removes fluorine and arsenic has the advantages such as removal effect is good, stable.
Artificial Wetland Techniques is a kind of water technology grown up gradually the fifties in 19th century, obtains in recent years and develops fast.The external research having carried out this field very early.Nineteen fifty-three, doctor Seidel of Germany finds that reed can remove organic and inorganics in a large number under study for action.Enter the sixties, these experiments extend to many large scale experiments from observation, start artificial swamp research boom.Seidel and Kickuth cooperates to propose root domain tyeory in 1972, the eighties, artificial wet land system entered the application stage by experimental stage, the country such as Germany, Denmark, Austria, Belgium, Holland establishes a large amount of Reed Bed systems in succession, is mainly used in the sewage disposal of samll cities and towns.Current free water surface wetland is main treatment wetland in North America, as there are 600 many places artificial swamp engineerings in the U.S. for the treatment of municipal administration, industry and agricultural effluent; European, Australian more employing be drowned flow artificial wet land technique, Denmark, Germany, each country of Britain have 200 systems at least in operation.Artificial swamp compared with traditional sewage water treatment method, have treatment effect good, build and working cost is low, treating processes energy consumption is low, be easy to the advantage such as maintenance management, good landscape effect.
In recent years, scholars has carried out large quantifier elimination to the application of wetland and mechanism, but all mainly concentrate on the research of process sanitary sewage, mining wastewater etc., principal pollutant are nitrogen phosphorus and heavy metal etc., and for the fluorine-containing rare report for the treatment of research with the sewage of arsenic.
Summary of the invention
The object of the invention is to propose a kind of for fluorine-containing and arsenic sewage, floor space is little, remove materialization-artificial wetland combination treatment process that fluorine effect of removing arsenic is good, investment running cost is low.
For achieving the above object, technical scheme of the present invention is as follows:
This system is made up of the apparatus for physical Chemical treating be linked in sequence and artificial wetland treatment device, carries out pre-treatment by apparatus for physical Chemical treating, and artificial wetland treatment device is further processed;
Described apparatus for physical Chemical treating is by water inlet system, and adsorption stuffing layer and outlet system form; Fill thick pebbles below adsorption stuffing layer, the water inlet pipe of described water inlet system is placed between thick pebbles, is lower floor's water inlet; Be filled with thin pebbles above adsorption stuffing layer, to prevent adsorption stuffing from floating, filter water outlet;
Described artificial wetland treatment device comprises upper strata wetland, lower floor's wetland, water inlet system and effluent collection system; Planting plants in the wetland of described upper strata, the mixture of filling soil and thin cinder, is conducive to the absorption of plant, microbial growth and fluorine and arsenic, is provided with upflow tube above the wetland of upper strata; Described lower floor wetland fills rough coal slag, is conducive to the filtration of microbial growth and sewage; Thick pebbles is filled with below lower floor's wetland; Described water inlet system is the upper strata water distributor be placed in above the wetland of upper strata; The rising pipe of described outlet system is positioned at bottom wetland, and water outlet discharges system by U-shaped pipe, and water outlet pipe part is provided with exhaust-valve;
