The anti-clogging wastewater treatment process has the advantages that (1) the packing layer has the optimal hydraulic load and is not easily clogged; (2) the sewage is automatically guided to horizontally flow to a region with relatively high porosity, so that clogging caused by over-high load at one position is avoided; (3) the packing layer has good adsorbability and high dirt-carrying capacity; and (4) small units are adopted to distribute water; and water distribution is relatively uniform.
Description
Technical field
The present invention relates to water treatment field, particularly relate to a kind of anticlogging sewage treatment process.
Background technology
In any type of sewage treatment process, biofilter material, through just there will be blocking after a period of time, is traced it to its cause, the mainly blocking that causes of a large amount of gatherings of suspended substance to the blocking in filtrate space, microorganisms producing breeding and extracellular polymeric.Filter clogging has had a strong impact on treatment system and has normally run, and reduces processing efficiency, increases operation cost.
Summary of the invention
The present invention starts with from the intelligent distribution voluntarily of current, to solve in sewage disposal, and the blockage problem of filtrate.
A kind of anticlogging sewage treatment process, comprises the steps:
(1) solid impurity in sewage is removed;
(2) sewage processed through step (1) carries out denitrogenation dephosphorizing process by water distributor to feeding microbiological media oxidizer;
(3) sewage processed through step (2) is sent into denitrification pond and is carried out denitrification process.
Described microbiological media oxidizer main body is alternately made up of main biologic packing material layer and auxiliary packing layer, prevents gas-liquid two-phase skewness in packing layer, thus affects treatment effect.Auxiliary packing can guide sewage according to the drag size of main biofilm packing, and within the as far as possible short time, horizontal flow is to the larger region of porosity.
Described main biologic packing material layer is by quartz sand, form containing iron sand and clay.Main biologic packing material adheres to a large amount of microorganism, in anhydrous conditions decomposing organic matter as early as possible, to ensure the porosity of ecological filler.
Preferably, the described each components by weight of main biologic packing material layer is 5:3:3.
Quartz sand has inclusion-free, and without corner angle, density is large, physical strength is high, the feature that dirt-carrying ability life cycle is long, has larger aperture containing iron sand, more surface-active functional group and stronger electric charge mutability, make it have good adsorption to organism; Secondly be rich in the compositions such as a large amount of Ca, Al and Fe in main filler, be easy to react with the organism in sanitary sewage.Clay is a kind of important raw mineral materials.Have the characteristics such as surface charge, structure channel and high specific surface area, simultaneously the interlamination region of clay is a good chemical reaction place, has the characteristics such as Inter layer exchange, absorption, polymerization.This packing layer has the hydraulic load of best the best, is not easy blocking.
Preferably, described auxiliary packing is the spherical cavity filling of PVC material.
Preferably, described microbiological media oxidizer is respectively from top to bottom: the first auxiliary packing layer, the first main biologic packing material layer, the second auxiliary packing layer, the second main biologic packing material layer.
Preferably, the thickness of each layer of microbiological media oxidizer is respectively: 10cm, 10cm, 10cm, 20cm.
Preferably, described microbiological media oxidizer is all covered with gravel bed up and down, and the thickness of described gravel bed is 10cm.Prevent root system of plant from arriving auxiliary packing, affect the treatment effect of filler; Nethermost gravel bed is used for the rising pipe of pre-buried surrounding water outlet.
Further, described water distributor is positioned at the first auxiliary packing layer, and water distributor is arranged along filling pipe, and adjacent water distributor is spaced apart 2m.
The present invention has following beneficial effect:
(1) packing layer has the hydraulic load of best the best, is not easy blocking;
(2) automatically guide sewage horizontal flow to the larger region of porosity, avoid certain load excessive, result in blockage;
(3) packing layer has good adsorptivity, and dirt-carrying ability is strong;
(4) adopt junior unit water distribution, water distribution is more even.
Accompanying drawing explanation
Fig. 1 is microbiological media oxidizer cross-sectional view of the present invention;
Fig. 2 is water distribution junior unit schematic diagram of the present invention.
Embodiment
In order to make those skilled in the art understand technical scheme of the present invention better, below the invention will be further described:
Sewage, successively by coarse rack, fine fack, after removing the rubbish things such as the plastics in water body, enters settling tank and leaves standstill, remove the heavy particulate matter such as sand; Sewage after precipitation enters equalizing tank, is fully mixed by various sewage, to ensure the constant of the sewage quality of the microbiological media oxidizer entering next step.
The sewage of equalizing tank enters the process of microbiological media oxidizer by water distributor.Described microbiological media oxidizer main body is alternately made up of main biologic packing material layer and auxiliary packing layer.When packing layer is higher, need to carry out segmentation, centre arranges apparatus for redistributing.
Main biologic packing material layer is by quartz sand, form containing iron sand and clay, and each components by weight is 5:3:3.
Auxiliary packing layer is made up of the spherical cavity filling of PVC material, this spherical cavity filling by two hemisphere synthesize one spherical, each hemisphere has 12 half fan-shaped blades, the fan-shaped blade of two hemisphere staggers mutually.This filler feature is that specific surface area is large, and voidage is higher, and sewage can be guided according to the drag size of main biologic packing material, and within the as far as possible short time, horizontal flow is to the larger region of porosity, avoids certain load excessive, results in blockage.
As shown in Figure 1, microbiological media oxidizer is followed successively by the first thick auxiliary packing layer 1 of 10cm, the first main biologic packing material layer 2 that 10cm is thick, the second auxiliary packing layer 3 that 10cm is thick, the second main biologic packing material layer 4 that 20cm is thick from top to bottom.Lay one deck above it and be not less than the thick artificial soil of 10cm 5, for planting greening, reducing and taking up an area.
Microbiological media oxidizer surrounding lays the thick gravel bed of one deck 10cm 6.
For improving water distribution hydraulics further, make whole water distribution big unit hydraulic pressure substantially identical, as shown in Figure 2, we take the setting of water distribution junior unit.
Water distributor 7 is positioned at the first auxiliary packing layer 1, water distributor 7 adopt the pvc pipe of DN75.On to be often separated by 2m place arrangement water distributor 8.Water distribution unit is divided into the junior unit of 2m × 2m, water distributor 8 is positioned at its middle.Water distributor 8 eight direction water distribution uniformities, ensure that the organic loading of all main biologic packing materials is basically identical.
Mode above only by illustrating describes some one exemplary embodiment of the present invention, undoubtedly, for those of ordinary skill in the art, when without departing from the spirit and scope of the present invention, can revise described embodiment by various different mode.Therefore, above-mentioned accompanying drawing is illustrative with being described in essence, should not be construed as the restriction to the claims in the present invention protection domain.
