Description
Technical field
The present invention relates to technical field of sewage, be specifically related to a kind of double-layer artificial wetland system and working method thereof of strengthening sewage denitrification and dephosphorization, the method for mainly utilizing artificial swamp to dispose of sewage reaches the purpose of strengthening sewage denitrification and dephosphorization.
Background technology
Polluted water land is handled artificial wetland technology, and (Constructed Wetlands CWs) has become a kind of water pollution control technology of World Focusing.Artificial swamp openly is reported in 1904 the earliest, but formally as a kind of sewage disposal technology, then rises countries such as U.S. the seventies, Australia, Holland, Denmark, Britain, and it develops rapidly and then is recent two decades.In recent years, the artificial swamp research that is applied to handle domestic sewage of villages and small towns, control widespread pollution from the overuse of fertilizers and pesticides in rural area and rivers and lakes eutrophication appears in the newspapers repeatly.
Yet deficiencies such as traditional artificial swamp pollutant load is low, floor space is big, easily obstruction, oxygen supply deficiency, denitrogenation dephosphorizing effect are undesirable have restricted the tempo and the application scale of artificial swamp.
At artificial marsh sewage treatment system oxygen supply deficiency, present research mainly concentrates on the following aspects: the strong plant of (1) screening reoxygenation ability, but wastewater treatment efficiency higher to concentration, that load is big is not obvious, can not solve the seasonal difference of plant reoxygenation; (2) increase artificial swamp processing unit flow process or reduction load; (3) increase pre-treatment, as before the soil is handled, increase nitrated section or to sewage preaeration to improve the dissolved oxygen of intaking etc.; (4) in the artificial marsh sewage treatment system in conjunction with artificial aeration's technology, replenish the inner dissolved oxygen of wetland, this method can improve plant do not grow up to before and the treatment effect of land system when winter, the plant effect weakened, but increased energy consumption and working cost; (5) water pump lifting or utilize the physical features drop to carry out drop oxygenation.
At the characteristics of artificial marsh sewage treatment system denitrification weak effect, present research mainly concentrates on the following aspects: (1) segmental influent, with former water as carbon source; (2) increase return-flow system, with the part effluent recycling; (3) control condition is in inner aerobic zone and the oxygen-starved area of forming of medium.
Not good at the artificial swamp phosphor-removing effect, present research mainly concentrates on the following aspects: chemical methods such as (1) employing flocculation sediment carry out pre-treatment to sewage; (2) in artificial swamp, increase filler to the plain high adsorption capacity of phosphorus; (3) connect land percolation even depth processing unit after, the phosphorus element in the artificial wetland effluent is removed in absorption.
There was following problem in the research of artificial swamp and the application process: low based on easy obstruction of the wetland of soil or fine sand and pollutant load in the past; There is the insufficient problem of oxygen supply in the simple plant reoxygenation that relies on, the ammonia nitrogen removal weak effect, and take the artificial aeration to increase energy consumption and working cost; Wetland back segment carbon source deficiency causes the denitrification denitrogenation effect undesirable; Introduce as efficient dephosphorization filler such as slag, slag, quartz sand and mainly rely on the adsorption dephosphorization, the physico-chemical property of filler itself may be brought negative impact to the growth of wetland plant on the one hand, the displacement of adsorbing saturated back filler on the other hand causes the increase of cost of investment, and the treatment and disposal of adsorbing saturated back filler has the potential secondary pollution problems.
Summary of the invention
One of purpose of the present invention provides the double-layer artificial wetland system that a kind of floor space is few, be difficult for obstruction, good denitrogenation and dephosphorization effect, strengthening sewage denitrification and dephosphorization that investment running cost is low, adopt double-deck vertical current constructed wetland system, for the villages and small towns scattering sewage treatment provides a valid approach.

Step b. enters the wetland II of lower floor after entering the effects such as mineral filler 14 absorption, microbiological deterioration and plant absorbing of sewage in the wetland I of upper strata among the wetland I of upper strata, and mixes water filling with mixed formation of sewage that enters among the wetland II of lower floor;
After the Degradation that step c is mixed the microorganism of apposition growth on the biologic packing material 13 of water filling in the wetland II of lower floor was handled, what finally enter the wetland II of lower floor bottom went out water collection pipe 7, discharges by going out water collection system.
Apply the present invention to the processing of certain village sanitary sewage, the design flooding velocity is 10m
3/ d, sewage quality is: SS:20～40mg/L, COD:100～200mg/L, BOD
5: 50～100mg/L, NH
3-N:15～40mg/L, TN:25～50mg/L, TP:2.0～5.0mg/L.
Sewage at first flows into wet land system water inlet manifold 2, by flowrate control valve 3, is assigned to upper strata water distributor 4 and lower floor's water distributor 5 in 3: 1 ratios again.The upper strata water inlet evenly drops to wetland I upper strata, upper strata by the at interval uniform aperture of upper strata water distributor 4 upper tops, sewage through drop oxygenation vertically infiltrates upper strata Wingdale and zeolite fill area, the residence time is 2d, by effects such as filling adsorption, microbiological deterioration and plant absorbing, effectively remove pollutents such as suspended substance, organism, ammonia nitrogen, phosphorus.Lower floor water inlet is overflowed through lower floor's sawtooth overflow cloth tank 6 by lower floor's water distributor 5 through straight tube 16, with after the upper strata water outlet mixes, evenly flows into lower floor's biologic packing material 13 districts at middle level pebbles fill area, is 1d the wetland II residence time in lower floor, mainly removes nitric nitrogen.The final back water of handling goes out water collection pipe 7 collections and imports outfall sewer 8 through the wetland II of lower floor bottom, discharge behind water outlet U-shaped pipe 10.
Wetland water level inside 0～100mm more than filling surface in spring in the operational process, summer is 100～200mm more than filling surface, and winter is 50～100mm below filling surface, and its water level is highly regulated by adjusting water outlet U-shaped pipe 10; Device operation is normal in the entire treatment process, and no latch up phenomenon does not need the situation of emptying.
Result shows: during steady running, effluent quality is as follows: SS:5～10mg/L, COD:25～60mg/L, BOD5:5～20mg/L, NH
3-N:5～15mg/L, TN:8～20mg/L, TP:0.5～1.0mg/L, pH:6～9, turbidity is stabilized in below the 5NUT, and effluent quality reaches " urban wastewater treatment firm pollutant emission standard " (GB18918-2002) one-level B standard.
The above only is one embodiment of the present of invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
