Description
Technical field
This utility model relates to the technical field of sanitary sewage disposal, the particularly sewage disposal of combined three-dimensional biological rotating disk
System.
Background technology
Sanitary sewage is mainly made up of feces and wash water, containing substantial amounts of Organic substance, nitrate, mud or floating
Things etc., wherein Organic substance is under anaerobic bacteria effect, easily gives birth to odorant, produces parasitic ovum etc.；Wherein in water, nitrate is
Under aerobic environment, in the nitrogen-containing compound with various forms, most stable of nitrogen compound exists, and is also that itrogenous organic substance is through nothing
The catabolite of machine effect terminal stage.The toxicity of nitrate own is the lowest, but it can be reduced to after entering human body
Nitrite, toxicity strengthens, is 11 times of nitrate toxicity.The primary biological effect of nitrite is exactly by normal blood red egg
It is oxidized to that not there is conveying oxygen ability in vain, thus reduces hemoglobin and send the ability of oxygen to the defeated metahemoglobin of body.When
Methemoglobinemia will be become (as Huang withers when metahemoglobin concentration reaches more than the 10% of Hb A hemoglobin adult concentration
Disease etc.), occur skin cyanosis, dizziness, feel sick, palpitate quickly, dyspnea, weak, suffer from abdominal pain, the clinical symptoms such as diarrhoea, higher
Concentration can cause the even death that suffocates.It is metahemoglobin that hemoglobin in infants is easier to by nitrite-oxidizing,
And in infants, there is no methemoglobin reductase, so affected more susceptible to nitrate or nitrite.Meanwhile,
Nitrite has the effect of antithyroidin, even if in the highest area of content of iodine, such as Nitrate In Drinking Water, nitrite
Content high, also result in endemic goiter equally, and the human body utilization to vitamin A can be disturbed, cause vitamin A
Deficiency disease, blood matter declines, and cardiac vagus nerve in suppression makes tachycardia.And mud discharging understands contaminated soil after irrigation canals and ditches, finally
Polluted underground water.Therefore the Organic substance in sewage, nitrate, mud and floating thing must be filtered out, and through follow-up technique
Process just can be discharged after reaching discharging standards.And existing processing system to there is sewage load little, treatment effect
Difference, the defect that treatment effeciency is low, use water pump to carry sewage between the most each operation, the drift in course of conveying, in sewage
Float, silt etc. can block water pump, and this adds maintenance cost beyond doubt.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, it is provided that a kind of compact conformation, employing overflow-type are defeated
