Abstract
The present invention relates to a kind of Pig farm wastewater treatment systems, it is the device that a kind of pair of Pig farm wastewater carries out that decontamination cycle uses, the system includes seven units, water collect tank is separated by solid-liquid separation strainer, hydrolization and acidification tank, tank for sewage gas, bio-matrix tank, multistage water plant ecological pool, after seven grades of processing, water quality meets《Livestock and poultry breeding industry pollutes pollutant catabolic gene discharge standard》, have the effect of simple, at low cost, high-efficient purification.
Description
Technical field
The invention belongs to pig-breeding technical fields, especially relate to a kind of resource reutilization technique of pig manure in breeding process.
Background technique
Pig is the maximum breed variety of animal husbandry, and Pig raising wastewater mainly has the urine and excrement of the live pig excretion on pig farm,
Rinse pig house waste water and during pig-breeding, worker generate it is a small amount of produce, sanitary wastewater.Pig raising wastewater and pig farm
Scale, live pig gender, feed for nursing type, pig growth phase, feeding manner, cleaning up excrement mode, nursing facility, weather condition etc. are more
Kind factor is related, since the breeding facility on each pig farm, management method and production method etc. are different, the production of piggery wastewater
There may be very big differences for the pollutional load of raw amount and Pig raising wastewater.
Pig raising wastewater is mainly made of urine, flushing water, sanitary sewage etc., and typical waste water quality feature is than 1：pH
7.90, SS 7200mg/L, biochemical oxygen demand (BOD) (BOD) 9400mg/L, total nitrogen (TN) 2500mglL, total phosphorus (TP) 330mg/L, Cu
4.70mg/L Zn12.0mg/L.Rich in such a large amount of nitrogen and phosphorus pollutants in Pig raising wastewater, if being directly discharged into rivers, lake etc.
In water body, it will phenomena such as causing water eutrophication, wawter bloom, red tide occurs, cause serious water environment pollution.Livestock and poultry cultivation
The main water pollutant of industry, total nitrogen and total phosphorus emission are respectively 102.48 ten thousand tons and 16.04 ten thousand tons, and it is total to account for about national water pollution
Nitrogen, the 21.7% of total phosphorus emission and 37.9%.The loss of nitrogen phosphorus not only results in water pollution problems, Er Qiezao in Pig raising wastewater
At the waste of resource.
Natural treatment mode generally includes water body self-purification and soil natural purification two types.Water body self-purification master
It to be realized by Anaerobic Treatment, the processing of amphimicrobian oxygen, Aerobic Process for Treatment and aerated pond processing.Natural facture has small investment, energy
Consume feature small, that operating cost is low, and to be difficult to degrade in waste water organic pollutant, nutritional ingredients and the cause of disease such as N, P
The removal effect of body and stink is all more satisfactory.
In the prior art, the system that artificial swamp, plants filtering bed etc. are had ecological restoration function is applied to dirt
Water process, but there has been no the restorative procedures of whole system.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of Pig farm wastewater treatment systems.
The present invention is achieved by the following technical programs.
The present invention provides a kind of Pig farm wastewater treatment systems comprising：
(1) water collect tank, for collecting pig farm raw water；
(2) it is separated by solid-liquid separation strainer, for separating liquid in water collect tank；
(3) hydrolization and acidification tank, the liquid acid-base property after adjusting separation；
(4) tank for sewage gas carries out biogas fermentation to the liquid after adjusting acid-base property, and the biogas of generation is recycled, natural pond
After liquid carries out flocculation sedimentation, bio-matrix tank is sent to from pot bottom separation；
(5) bio-matrix tank, to adsorb and degrade；
(6) multistage water plant ecological pool passes through the heavy metal and nitrogen phosphorus in the photosynthesis degradation sewage of water plant
Pollutant；
(7) water quality in ecological pool is monitored, enters pig farm after up to standard and recycles again.
In the bio-matrix tank, using straw, stalk, rice husk, rice bran, sawdust, oil cake, active carbon as matrix, lead to
Cross the effect of anaerobism or amphimicrobian flora in biogas slurry, the pollutant in further degrading waste water.
The bio-matrix tank can be replaced with bio-matrix pond, the deep 70~90cm in pond, and every grade matrix pool area is 200~
3000m2, the residence time of every grade of sewage are 10 days, and matrix addition 50kg/m2 is carried out partly or entirely more for every 3 months
It changes.
The water plant is emergent aquactic plant, fluitante, submerged plant, floatingleaved plant.
The water plant is：Water spinach, rape, canna, water hyacinth, water peanut, water lettuce, hornwort, watermifoil, the marshland full of water weeds
Grass, eel grass, hydrilla verticillata, potamogeton malaianus, Potamogeton maackianu, waterweed, stonewort.
Culturing fish and shrimp simultaneously is gone back in the water plant ecological pool.
Pig farm raw water after collecting-tank, separation of solid and liquid, hydrolysis acidification, anaerobic fermentation and flocculation sedimentation, CODCr,
BOD5 and SS are greatly reduced, but ammonia nitrogen and total phosphorus are still higher, by bio-matrix tank adsorb and degrade after, by ecological pool into
One step degradation eutrophic water, reaches by reparation《Livestock and poultry breeding industry pollutes pollutant catabolic gene discharge standard》.
The present invention constructs Wastewater from Pig Farm purification system by seven grades of processes, finds after testing, final water quality symbol
National emission standard is closed, can recycle and be introduced into pig farm and utilize again, substantial saved pig farm water, realize pig farm
Non-wastewater discharge and ecological circulation.Whole system construction cost is low, is suitable for most of farm.
Specific embodiment
Technical solution of the present invention is described further below, but claimed range is not limited to.
Embodiment 1：
A kind of Pig farm wastewater treatment system comprising：
It collects pig farm raw water and enters water collect tank, by being pumped into hydrolization and acidification tank after strainer, the liquid acid after adjusting separation
