Abstract
The invention discloses an aquatic plant filter system for purifying breeding wastewater containing antibiotics. The invention relates to a wastewater treatment system which is an ecological treatment system applicable to deeply treating breeding wastewater. Plants in the aquatic plant filter system are cultivated on a PVC (Polyvinyl Chloride) floating board with holes; after the wastewater passes through the aquatic plant filter bed, pollutants such as nitrogen and phosphor and antibiotics in the wastewater are effectively lowered. The aquatic plant filter system disclosed by the invention utilizes aquatic plants to deeply treat the breeding wastewater, is simple to operate, low in investment and operation cost, not only can well remove nitrogen-phosphor nutrient salts and antibiotics in wastewater, but also improve water treatment effect; meanwhile, the harvested aquatic plants can be used as feed of livestock, so that treatment cost of the breeding wastewater is lowered.
Description
technical field
The present invention relates to the waterplant filter bed system of a kind of purification containing microbiotic breeding wastewater, belong to water pollutant control and prevention and control field.
background technology
In recent years, livestock and poultry breeding industry obtains fast development in China, and the fast development of pig-breeding industry is in meeting people's lives demand and promoting rural economic development, and the environmental problem that the discharge of wastewater of raising pigs brings is also day by day serious.The waste water of large-scale pig farm, after exemplary process art breading such as " solid-liquid separation-anaerobic-aerobics ", still contains the pollutents such as large amount of organic, high concentration N-P and residual antibiotic in the waste water of discharge.Compare with the harm of nitrogen phosphorus with COD in waste water, the residual antibiotic in waste water has more serious potential hazard.Most microbiotic for animals has very wide antimicrobial spectrum, the intrinsic eubiosis in meeting welding; Meanwhile, long-term exposure is in low dosage microbiotic environment, and every physiological function of the mankind can be subject to severe jamming.Research both at home and abroad all shows, near the multiple environment such as the soil and groundwater of antibiotics resistance gene plant, all detects.
The ecological treatment system such as oxidation pond, artificial swamp has the advantages such as cost less energy-consumption is few, but floor space is large, it is also apparent to produce the shortcomings such as secondary pollution.In recent years, the aquatic economic vegetables such as mater convolvulus, green water cress are used to sewage treatment area, can not only effectively remove the pollutents such as nitrogen phosphorus, can also obtain certain economic benefit by results plant.Therefore, provide a kind of technique of utilizing aquatic vegetable to process aquaculture waste water to there is certain using value.
summary of the invention
The object of the invention is to provide the waterplant filter bed system of a kind of purification containing microbiotic breeding wastewater, is removing nitrogen phosphorus, organicly microbiotic is also being had to good removal effect simultaneously.
The present invention realizes by following steps the purifying method of piggery wastewater:
(1) soft cellulose filler is assembled in PVC kickboard;
(2) choose economic aquatic plant field planting on PVC kickboard;
(3) the PVC kickboard of field planting plant is covered to the breeding wastewater water surface;
(4) adopt intermittent aeration mode to carry out oxygenation aeration near water body roots of plants district;
(5) economic vegetables are carried out to daily administration and periodical reaping;
The soft cellulose filler that step (1) is described, is characterized in that soft cellulose filler is taking the fine synthetic fibre of hydroformylation as basic material.The fiber rope series winding that spins stranding is pressed with fiber yarn plastics disk evenly distributedly, composition certain length ground cell fiber bundle.Described PVC kickboard, is characterized in that PVC kickboard thickness is 10mm, and long × wide is that 1.0 m are that dimension silk evenly divides, and every kickboard is provided with 80 holes, and aperture is 2cm.Between each block of plate, available latch connects and fixes.Self there is stronger buoyancy.
The waterplant that step (2) is described, is characterized in that the waterplant of choosing is the vegetables that mater convolvulus, green water cress etc. have economic worth.In southern area of China, mater convolvulus is adapted at summer culture, and be best planting time May to October; Green water cress is adapted at Winter Cultivation, and be best planting time April October to next year then.Mater convolvulus and green water cress all adopt cottage propagation, take reclining posture to plant the field planting of seedling mode.
Breeding wastewater described in step (3) adopts flow by gravity mode to enter the gallery of brick mix structure, and the gradient of gallery bottom is 1%.Gallery front end arranges inlet channel, ensures system water distribution uniformity and keep good hydraulic flow state, makes fully to be degraded into the pollutent in water; Gallery end sets out tank, and waste water after treatment is discharged by effluent trough.Waste water mode with plug-flow in gallery flows to water outlet by water-in.
The described oxygenation aeration of step (4) adopts air compressor pump, in the mode of intermittent aeration near water body aeration roots of plants district.Adopt time control switch to regulate aeration intensity by controlling aeration time, gallery water inlet aeration intensity, higher than water outlet, makes dissolved oxygen concentration in water body have certain gradient.
The described daily administration of step (5) mainly comprises cultivated plant water logging state and pest control, determines the water logging degree of depth of cultivated plant according to vegetation growth state.Described periodical reaping is to take different harvesting modes according to the aquatic plants growth situation of cultivation, and cultivated plant is gathered in it after growing into 25 cm height, and the height for the stubble left is 10 ~ 15 cm.
Advantage of the present invention mainly comprises:
(1) the present invention can reduce organism and concentration of nitrogen and phosphorus in piggery wastewater effectively, also very obvious to antibiotic removal effect;
(2) the PVC kickboard that the present invention adopts generally can be used more than 5 years, and PVC kickboard cost is lower and processing is simple;
(3) Summarization for Piggery Wastewater Treatment Technology the present invention relates to, in the time disposing of sewage, the aquatic vegetable of output can be used as feed or carries out pooling of resources processing;
In a word, the waterplant filter bed technical finesse piggery wastewater that utilizes cultivation aquatic vegetable, technique is simple, and investment and working cost are cheap, in removing Pollutants in Wastewater, the aquatic vegetable of output can produce certain economic benefit, has really realized unification social, environment and economy benefit.
