Mainly contain following regulating effect:
1. the surge capability to sewage treatment load is provided, prevents the sharply change for the treatment of system load;
2. reduce the fluctuation entering the treatment system discharge of sewage, when making to dispose of sewage, the feed rate of chemical used is stablized, and is applicable to the ability of feeding equipment;
3. in the pH value, stabilizing water quality of control sewage, the neutralising capacity of different sewage self can be utilized, reduce the consumption of chemical in neutralizing effect;
4. prevent the toxic substance of high density from directly entering biochemistry treatment system;
Preferably, can in equalizing tank 3 quartz sand filtration layer and/or activated carbon filter layer, strengthen filter effect further.
Utilize the effect of anerobe in described anaerobic pond 4, organism be hydrolyzed, acidifying and methanation, remove the organism in waste water, and improve the biodegradability of sewage, be conducive to follow-up aerobic treatment.
The anaerobic degradation process of macromolecule organic is divided into hydrolysis stage, fermentation (or acidifying) stage, produces acetic acid stage and methane phase stage four-stage.
Described anoxic pond 5 is for coordinating the subsequent disposal of Aerobic Pond 6, and in this treating processes, main operation adds phosphorus.
In described Aerobic Pond 6, microorganism decomposes organism, absorbs, and absorbed nitrogen, phosphorus, by denitrification denitrification, the phosphorus removed in this process is far longer than the phosphorus that anoxic pond 5 adds, the main object of this treatment step is denitrogenation dephosphorizing, and the material be eliminated here finally occurs in form of a sludge.
Described second filtering basin 8 are arranged on Aerobic Pond 6 rear, and its volume or width are arranged to identical with Aerobic Pond 6 or larger.Preferably, the water outlet pipe in the second filtering basin 8 arranges lower than water inlet pipe position, is provided with one or more dismountable ramped shaped filtering layer 12, for filtering out the mud in Aerobic Pond 6 between two pipes.
Described ramped shaped filtering layer 12 is 5 °-45 ° with horizontal plane angle, is preferably set to 25 ° of angles.Be placed with sterilizing agent in described sterilization pool 9, carry out disinfection for the water after filtering filtering basin 8.
Preferably, in described tank body 100 from left to right successively six roots of sensation pipe 2 be 1:3:3:3:3:2 apart from the aspect ratio of tank body 100 bottom surface.
Preferably, described anaerobic pond 4 volume is 1/3rd of equalizing tank 3, and the two width is identical.
Preferably, described anoxic pond 5 is 2/3rds of equalizing tank 3, and the two width is identical.
Because the biotechnological formulation that adopts main in Aerobic Pond 6 carries out advanced treatment to the organism in sewage, the treatment time is longer, and treatment effect is more abundant.Therefore, Aerobic Pond 6 is preferably set to identical with the width of equalizing tank 3, and volume is identical, and the water outlet pipe 2 of Aerobic Pond 6 is arranged near top side location.
Preferably, the top of the corresponding each treating pond of described tank body 100 is provided with and windows 13.
Particularly, described domestic sewage treatment device is barrel-shaped in the present embodiment, in actual applications, can be designed to any shape of needs, as drum type, square column type etc. according to practical situation.
Particularly, at this according to the treatment time of anaerobic pond 4, anoxic pond 5, Aerobic Pond 6 pairs of sewage disposals and treating processes, three treating ponds are adopted step-like design, and the volume ratio in three ponds is 1:2:3, not only meeting the sufficient reaction times also achieves self-draining object.
In the utility model, each treating pond cuts off with dividing plate 14 successively, and dividing plate 14 does not contact tank body 100 top completely, leave perforate, be convenient to the air pressure balancing whole tank body, wherein each treating pond width ratio is followed successively by 1:1:1:1:1:2:2, according to treatment time of sewage and flow, the width in each pond is arranged to certain proportion, contributes to processing sewage further.
Wherein, in described tank body 100, six roots of sensation pipe 2 is 1:3:3:3:3:2 apart from the aspect ratio of tank body 100 bottom surface successively from left to right, here according to flow and the reaction times design of sewage, wherein in the first filtering basin, pipe rational height is minimum, here consider that two-layer filtering net is arranged at the top in the first filtering basin, need to utilize from bottom pressure injection formula to be pressed into equalizing tank by sewage; In equalizing tank, need certain reaction times, Gu arrange the highest by the height of pipe, because designing the volume size in three ponds in anaerobic pond, anoxic pond, Aerobic Pond, therefore, pipe is designed to equal height; Need filtering net to be installed, Gu by the middle part of the Position Design of pipe in the second filtering basin in the second filtering basin; The object of pipe design certain altitude is the automatic flowing realizing filling with sewage in body, no longer needs the management of personnel.
In one embodiment: tank diameter is 1.6m, width is 9m, and the height of its median septum 14 is 1.5m, and the first filtering basin height is 1.5m, and width is 1m, and pipe height is 0.4m; Equalizing tank height is 1.5m, and width is 1m, and pipe height is 0.4m; Anaerobic pond height 0.5m, width is 1m, and pipe height is 1.2m; Anoxic pond height 1m, width is 1m, and pipe height is 1.2m; Aerobic Pond height 1.5m, width is 1m, and pipe height is 1.2m; Second filtering basin height 1.5m, width is 2m, and pipe height is 0.8m; Sterilization pool height 1.5m, width is 2m.
The making material that the utility model adopts adopts fiber composite resin, and be commonly called as glass reinforced plastic, have lightweight, corrosion-resistant, impact-resistant feature, considers that described domestic sewage treatment device is embedded in underground, therefore selects fibre resin as the making material of this equipment.
Should be understood that, above-mentioned embodiment of the present utility model only for exemplary illustration or explain principle of the present utility model, and is not formed restriction of the present utility model.Therefore, any amendment made when not departing from spirit and scope of the present utility model, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.In addition, the utility model claims be intended to contain fall into claims scope and border or this scope and border equivalents in whole change and modification.
