Description
Technical field
The utility model belongs to agricultural non-point source pollution control and administers field, specifically, being a kind of with denitrogenation dephosphorizing
The bio-matrix of advantage dissolves pond.
Background technique
With the fast development of China's agricultural and rural economy, intensive agriculture degree is continuously improved, chemical fertilizer, pesticide,
The agricultural chemicals such as film investment increases year by year, cultivates quantity and scale constantly expands, at the same time, agricultural input product utilization rate
Agricultural non-point source pollution problem caused by low, breeding waste processing lag etc. is got worse, and outstanding behaviours is south China earth's surface
Water water eutrophication, northern groundwater azotate pollution and marine red tide, green tide frequently occur, it has also become society and the common people are closed
The hot issue of note.
More particularly in addition to Farming, livestock and poultry cultivation is also most of peasant's production and living；It is both peasant
The important support of self-centered valuable source and rural economy.Since the 80's of 20th century, livestock and poultry cultivation starts not
Disconnected development, but large-scale cultivation starts to walk very late, to develop very slow.Aquaculture development is rapidly regional, and the intensive level of livestock and poultry is still
Universal lower, most of peasant household is based on dispersion raising livestock and poultry.Since livestock and poultry cultivation is substantially by self cultivation of casual household, lack
Weary specific ecomanagement.
It is shown according to the data statistics of State Ministry of Environmental Protection, national wastewater discharge is 684.8 hundred million tons within 2012, chemical oxygen demand
2423.7 ten thousand tons of amount discharge accounts for total COD discharge wherein the COD from agricultural sources discharges 1153.8 ten thousand tons
The 48% of amount, livestock and poultry breeding industry discharges 1099.0 ten thousand tons in the middle, and aquaculture discharges 54.8 ten thousand tons；Ammonia nitrogen discharge amount 253.6 ten thousand
Ton, 80.6 ten thousand tons of the ammonia nitrogen discharge amount of agricultural sources account for the 32% of total ammonia nitrogen discharge amount, wherein 15.2 ten thousand tons of planting industry, and livestock and poultry are supported
Grow 63.1 ten thousand tons of industry, 2.3 ten thousand tons of culture fishery.From data, it is apparent that the COD of livestock and poultry breeding industry and
Ammonia nitrogen pollutant occupies heavier ratio in agricultural pollution source, and livestock and poultry cultivation had been the main pollution of agricultural production pollution already
Source.
In addition to this, the provinces and cities that Chinese Ministry of Environmental Protection also concentrates nationwide scaleization livestock and poultry cultivation are investigated, as a result, it has been found that, state
Inside there is the scale livestock farming ratio for improving pollutant process facility not high, and the livestock and poultry of villager's free-ranging are then let alone pollutant
Processing.Livestock pollution load is big, pollutant component and its complexity, for example, excrement can bring a large amount of bacterial viruses, such as
Anthrax, bird flu, Brucella and tuberculosis etc.；The foul gas such as organic acid, ammonia, hydrogen sulfide, amine.If do not collect and
Processing in time, niff can not only be generated by arbitrarily stacking, but also with cleaning or rain drop erosion is thought, excreta incorporates
It flow to soil in water or water body is easy to spread the disease, leads to infectious diseases common to human beings and animals；In addition, a large amount of nitrogen and phosphorus element enters water
It will cause water eutrophication after body, endanger aquatile.In addition, peasant household uses novel fodder with the development of feed industry
Livestock and poultry are raised, contain the heavy metal elements such as copper, arsenic, mercury in feed addictive, are penetrated into water and soil with washing away for dampening, also easy pair
Environment causes damages.
In conclusion being related to the waste water such as the livestock and poultry cultivation of agricultural non-point source pollution, it is necessary to it is effectively controlled and is administered,
In previous design and engineering practice, there is two kinds of phenomenons for industry: one is simple extensive, such as septic tank or biogas treatment skill
Art, septic tank or biogas+filter tank technology, septic tank or methane-generating pit+land percolation technology, septic tank or methane-generating pit+stabilization pond skill
Art, septic tank or methane-generating pit+biological catalytic oxidation etc..These simple extensive processing techniques, make water outlet be extremely difficult to state
Family's " livestock and poultry breeding industry pollutant emission standard " GB18596-2001 standard.
Another kind, using anaerobism (UASB)+aerobic (A/O2)+MBR technology, film biochemical treatment (MCR)+advanced treating
(SRO particular technology) etc., this kind of technological investment and operating cost height, complex management bear raiser and breeding enterprise very big
Financial burden.It would therefore be highly desirable to improve.

131 material internal of phosphorus matrix is black, outside is red.Due to 131 large specific surface area of carbon elimination dephosphorization matrix, porosity is big, fills out
Expect that the factor is good, there is the suction-operated of strength to organic pollutant and phosphorus, rely primarily on Ca, Fe, Al Element release in material and gives up
Phosphorus element in water, which is formed, to be precipitated and the removal to phosphorus；Simultaneously because the low dissolved oxygen that water intake mode is carried under one's arms, can be realized denitrification
Carbon elimination phosphorus removal functional.
Through treated in second processing area 13, liquid enters third transition region 11c, in contact carbon elimination dephosphorization matrix 131
Lagging portion after microorganism and organic pollutant and phosphorus element generation biological respinse continues to react.
After third transition region 11c behind second processing area 13, liquid to be processed enters postposition area 18 to setting water level.
Preferably, lower than 13 water level of second processing area.
Preferably, low 100mm.
Filter substrate 181 is provided in postposition area 18, inside is grey, and outside is light red.Since filter substrate 181 is huge
The biodegrade for the biomembrane that the absorption crown_interception and host surface of big reference area and a large amount of micropore are formed
Depth carbon elimination denitrification dephosphorization function is completed in effect.
Through treated in postposition area 18, liquid enters the 4th transition region 11d, to liquid after treatment carry out rectification and
Clarification, is discharged after reaching " livestock and poultry breeding industry pollutant emission standard " (GB18596-2001) water quality indicator through liquid outlet 20.
