Description
Technical field
The present invention relates to a kind of sanitary sewage soil treatment technology, particularly a kind ofly be used for underground hollow billet infiltration water treatment method and the device of living scattered geographic sanitary sewage disposal and carry out the treating water reuse in urban residence sub-district, small towns, the village of having a holiday, sanatorium's five equilibrium.
Background technology
In recent years, along with development economic and society, the protrusion day by day of environmental problem, sewage disposal is not only also very urgent in the city but also in the area, small towns.Many closure body eutrophication situations are on the rise, and sewage disposal technology is not only required to remove organism, simultaneously the removal of nitrogen, phosphor contaminant are also had higher requirement.Simultaneously, because many regional water resources shortages are also increasing to the demand of reusing sewage.
With the activated sludge process is the traditional technology of representative, as aerobic/anaerobic technology (A/O), anaerobism/double oxygen/aerobic process (A
2/ O), sequencing batch activated sludge technology (SBR) etc., though the technology comparative maturity, the widespread use that expensive cost and operational and administrative expenses have limited them is particularly in the geographic application of small towns scattered settlement that lacks sewage collection system.
Conventional soil treatment process, as slow land treatment system, rapid infiltration system, overland flow system, sanitary sewage is had the treatment effect of economical and efficient usually, but these technologies also exist be subjected to environmental influence big, destroy ground landscape, emit bad smell, shortcoming such as floor space is big.
Summary of the invention
The objective of the invention is provides a kind of intensified water-layout underground infiltration water treatment method and device for urban residence sub-district, the small towns five equilibrium residence district of living scattered, can overcome effectively on the one hand exist in the prior art be subjected to environmental influence big, destroy ground landscape, emit bad smell, shortcoming such as floor space is big, make it have management simply on the other hand, save the characteristics of capital construction and working cost.
The objective of the invention is to be achieved through the following technical solutions:
A kind of intensified water-layout underground infiltration water treatment method, this method comprises the steps:
(1) below ground flora, arranges a plurality of diafiltration ditches and cloth tank, in the diafiltration ditch, be filled with and be beneficial to the artificial preparation soil that improves hollow billet wet performance, venting and water permeable performance and attached growth of microorganisms;
(2) water distributor through the preliminary sedimentation tank pretreated sewage is batched the diafiltration ditch by water distribution system in, enter the cloth tank through water distributor, under the artificial preparation soil hollow billet immersional wetting in the diafiltration ditch, by being arranged on the intensified water-layout material of cloth tank both sides, gradually to around soil diffusion, make it further enter katabatic drainage district between the diafiltration ditch;
(3) at soil under the comprehensive purifying function of---microorganism---botanical system sewage be purified, the water after the purification is discharged through header after collecting by the collecting gutter that is arranged on impervious barrier top, bottom.
Earth is by native soil and 8%～20% the turfy soil of mixing therein constitutes in the artificial preparation of filling in the diafiltration ditch described in the present invention.Perhaps by native soil and the turfy soil of mix therein 25%～40% slag and 8%～20% constitute.
For intensified anti-nitrated effect, raw waste water is shunted by 1: 1～4 splitting ratio, make it enter the shunting cloth tank that is arranged between the diafiltration ditch.
The present invention also provides a kind of enforcement system for carrying out said process, this system comprises a plurality of diafiltration ditches that are arranged in below the ground flora, in each diafiltration ditch, be provided with the cloth tank in the soil layer of certain depth, be provided with the porous water distributor in the cloth tank, the water distributor both sides are provided with the intensified water-layout material with good hollow billet wetting property, below the diafiltration ditch, be provided with impervious barrier in the soil of certain depth, be furnished with collecting gutter and header above the described impervious barrier.
Between the diafiltration ditch current fall stream district be provided with can intensified anti-nitrated effect shunting cloth tank and shunting water distributor.
The present invention compared with prior art, have the following advantages and beneficial effect: water distribution system is embedded in underground, is subjected to environmental influence little, can not distribute unpleasant odor, does not influence ground landscape, the earth surface planting lawn can directly combine with greening.Its water distributor buried depth only has 30～40cm, and the inflation that can make full use of thin solum passes the oxygen effect, and saves the excavation project amount.For the processing of middle-size and small-size town domestic sewage, the present invention and traditional active sludge treatment process and other soil treatment process relatively can be saved capital cost 50% ~ 80%, can save operational and administrative expenses 60%～100%, and management is simple; Removal ability to nitrogen, phosphorus is strong, and treat effluent water quality is good, water reuse in promptly can be used for after conventional liquid chlorine sterilization; The setting of intensified water-layout system has prevented the appearance in short-circuit flow and dead band effectively, has strengthened intrasystem water distribution uniformity effect, also helps reducing the even water supply of soil obstruction and ground flora.
