Abstract
The invention discloses a method for unpowered biological treatment of rural domestic sewage. The method comprises the steps of conducting entrapment to remove large particulate pollutants and flotage in sewage, conducting acidify degradation on organic pollutants to make organic pollutants converted into micromolecular organic pollutants easy to degrade, conducting primary filtration to remove fine particulate matter in sewage, conducting aerobic-anaerobic multi-level processing, conducting final filtration and entrapment on fallen aged biological films and conducting inspection. Continuous treatment can be achieved simply by introducing sewage constantly, exogenous power is not needed, and unpowered sewage treatment is achieved. According to the method, equipment construction cost is low and can be accepted by peasant households easily, treatment of domestic sewage of rural areas characterized in residence dispersal is realized, and environment pollution caused by domestic sewage is avoided; treatment effect is good, energy consumption is low, maintenance and using are convenient, and long-term use is possible.
Description
Technical field
The present invention relates to a kind of technology for treating domestic sewage in rural area, be specifically related to what a kind of domestic sewage in rural areas unpowered biological processed
Method.
Background technology
Along with progress and the socioeconomic development of human civilization, the mankind the most progressively recognize environmental conservation to promote social progress and
The significance of economic sustained, stable and coordinated development.Environmental protection work has become our fundamental state policy, by society
Can universal concern and attention.
While rural science and technology agricultural fast development, accelerate the paces of China's new countryside construction planning, will accuse in the near future
In the epoch " lived scattered " at each family in Bie Tong village, instead will be that life, medical treatment, science, culture " soft or hard " facility condition are neat
The general layout that Quan Tong village is lived in concentrated communities.Rural area live in concentrated communities life can not only accelerate infrastructure, education universal, moreover it is possible to be greatly enhanced agriculture
The living standard in village, but the ecological environment of surrounding will be brought the biggest challenge by the high-density aggregation pattern of population, wherein dirty
Contaminating the most prominent is exactly that people live produced sanitary sewage, and this seriously hampers the paces of new rural village development construction.
Domestic sewage in rural areas has the following characteristics that (1) domestic sewage in rural areas mainly includes kitchen cooking water, takes a shower and wash use
Water, is essentially free of heavy metal and poisonous and harmful substance in water, containing a certain amount of nitrogen, phosphorus, containing large amount of organic；(2)
Rural population is less, and widely distributed and dispersion, due to the restriction of objective condition, without sewage discharge pipe network, Domestic sewage collecting ratio
More difficult, lack unified management and administer；(3) domestic sewage in rural areas amount is less, concentration is low, and variation coefficient is big.For above-mentioned
The feature of country sewage, uses conventional effluent purification method to be difficult to obtain preferable treatment effect.Biomembrane is used to process life
Sewage, has the organic pollutant degradation efficiency advantage such as the most widely applicable high, real, mainly have biological rotating disk, bio-contact oxidation,
Bio-trickling filter, BAF, moving bed biological embrane method etc..But the method for above-mentioned existing treating sewage by using biological membrane is universal
Have that mosquitos and flies multiplies, big to the fluctuation of dissimilar wastewater purifying efficiency, the rudimentary operation stability of efficiency not enough, easily there is blocking and
Shorten the shortcomings such as cycle of operation.For preventing DeviceMode blocking, improving treatment effeciency, sewage pump etc. the most also can be used to carry
High effluent flow rate, operation energy consumption is high, and frequency of maintenance is high.
Summary of the invention
It is an object of the invention to overcome the shortcoming of prior art, it is provided that one can effectively purify domestic sewage in rural areas, energy consumption low,
The method that a kind of domestic sewage in rural areas unpowered biological of anti-equipment blocking processes.
The purpose of the present invention is achieved through the following technical solutions: a kind of method that domestic sewage in rural areas unpowered biological processes, it
Comprise the following steps:
S1. retain: collect domestic sewage in rural areas, retain through mechanical grille, remove the bulky grain pollutant in sewage and floating thing,
Waste water enters acidifying regulating reservoir；
S2. acidifying: have anaerobic acid-production microorganism in acidifying regulating reservoir, keeps the temperature of acidifying regulating reservoir to be 35～45 DEG C and filling
Being acidified to the pH value of sewage under the sealed environment of carbon dioxide to 3～4, macromole persistent organic pollutants are transformed into little molecule
Degradable organic pollution；
S3. initial filter: the sewage after acidifying flows to preliminary filter, cobble, meter Shi, the mixture of fine sand, institute are filled in described preliminary filter
State cobble, meter Shi, the weight ratio of fine sand are 5～8:3～5:1, the fine particulate material in preliminary filter removes sewage, water outlet
Flow in multistage comprehensive organism filter tank；
S4. anaerobic-aerobic multistep treatment: multistage comprehensive organism filter tank is made up of anaerobic pond and aerobic cell compartment, the sewage after initial filter
Through anaerobic-aerobic alternate treatment, water outlet flows into whole filter tank；
S5. filter eventually: whole filter tank is filled with the mixture of cobble, meter Shi, fine sand, described cobble, meter Shi, the weight ratio of fine sand
For 1:3～5:5～8, whole filter tank retains the aging biomembrane come off, and water outlet flows into inspection pond；
S6. inspection: inspection pond in cultivation have water plant, when aquatic plants growth health can water outlet, be the sewage after process.
Further, the quantity of anaerobic pond described in step S4 and Aerobic Pond is respectively 1～3.
Further, water plant described in step S6 is emergent aquactic plant, floatingleaved plant and submerged plant composition.
Further, described emergent aquactic plant is Rhizoma Acori Graminei, Mugil cephalus grass and Rhizoma Alismatis.
Further, described floatingleaved plant Herba Spirodelae grass and floating heart.
Further, described submerged plant hydrilla verticillata, hornwort and Herba vallisneriae Spiralis.
The domestic sewage in rural areas influent quality parameter of the present invention is as shown in table 1, the effluent quality parameter after the inventive method processes
As shown in table 2:
Table 1: influent quality requires (unit: mg/L)
| Project | CODCr | BOD5 | SS | Ammonia nitrogen | Vegetable and animals oils |
| Water inlet | ≤350 | ≤250 | ≤250 | ≤40 | ≤20 |
Table 2: effluent quality parameter (unit: mg/L)
| Project | CODCr | BOD5 | SS | Ammonia nitrogen | Vegetable and animals oils |
| Water outlet | ≤60 | ≤20 | ≤20 | ≤15 | ≤3 |
The invention have the advantages that
(1) present invention only need to persistently input sewage and just can realize continuous processing, it is not necessary to exogenous power, it is achieved at motorless sewage
Reason；
(2) construction cost of present device is low, easily accepts for wide farmers, solves sparsely populated domestic sewage in rural areas
Process, overcome the environmental pollution that sanitary sewage causes；
(3) high treating effect of the present invention, less energy consumption, maintenance are easy to use, can use for a long time.
