Description

A kind of harmless treatment three-grid septic tank

Technical field

The utility model belongs to domestic sewage treatment device technical field, and in particular to a kind of harmless treatment three is formatted excrement Pond.

Background technique

Septic tank as-it is a kind of it is easy, be widely used without the sewage treatment in situ facility of energy consumption.Septic tank benefit The impurity such as excrement, paper scrap, the suspended matter in sanitary sewage are retained with precipitation, and can be decomposed using anaerobic digestion effect Pollutant.Currently, the design of septic tank is normalized, and has become the main units of China's sanitary sewage treatment in situ, Wherein, three-grid septic tank is most widely used, but there are still some disadvantages for traditional three-grid septic tank, especially when excrement dirt When being discharged into septic tank, sewage water is larger, and septic tank volume is larger for water and sanitary sewage interflow, pool volume effective rate of utilization compared with It is low, it is easy short stream；It is high to be discharged concentration of suspension, and a large amount of microorganisms are easily lost with sewage.These all greatly reduce septic tank Treatment effect, and traditional three-grid septic tank easy fouling easily blocks after fouling.

A kind of Multifunctional three divisions septic tanks are disclosed for 200720084955.5 to this China Patent No., are related to sanitary sewage Septic tank in processing technology field.Above-mentioned utility model by be arranged successively have the 1st thereon, 2, (1,2,3) of 3 cover boards 1,2,3 lattice ponds (4,5,6) form；In the 1st lattice pond (4), upper part is disposed with downwards water inlet pipe (7) and inclination grid (10), bottom is different from the design of national standard septic tank, is tilting bottom of pond (14), is provided with the 1st and crosses the mouth of a river (12)；? In 3 lattice ponds (6), from _ top to bottm, it is disposed with the 2nd and crosses the mouth of a river (13) and outlet pipe (8), and the third lattice pond pool Nei Guo It is fixed with hanging filler (11) with fixed frame, forms anaerobe film.Above-mentioned utility model is a kind of structurally reasonable, pool volume Utilization rate is high, at low cost, less scaling, high treating effect, water outlet concentration of suspension is low, purifying property is high, promotional value is high Multifunctional three divisions septic tanks.

But there are still following defects for above scheme:

1, the right end bottom side that corresponding dirt is still easy to be deposited on the second lattice pond is still easy to appear accordingly for a long time Fouling condition.

2, inconvenient after corresponding dirt deposition regularly to clear up, while the pernicious gas generated during changing excrement is also retained It is easy to bring injury to exist simultaneously potential danger to service personnel in septic tank inner end, corresponding innoxious degree is lower.

Utility model content

The purpose of this utility model is to provide a kind of harmless treatment three-grid septic tanks, to solve in above-mentioned background technique The problem of proposition.

To achieve the above object, the utility model provides the following technical solutions: a kind of harmless treatment three-grid septic tank, packet Include septic tank ontology, the septic tank ontology is divided into the first lattice pond, the by the first partition and second partition of inner end Two lattice ponds and third lattice pond, first lattice pond upper end corresponding with third lattice pond is installed with capping, septic tank ontology upper end Equidistant through siphunculus is installed on, septic tank ontology upper end is fixed with cover by rivet, and the cover top, which is run through, to be stayed Equipped with to interface, the cover inner end corresponds to septic tank ontology upper end and is installed on filter cylinder by rivet, and intensively stays on the outside of filter cylinder Equipped with through-hole, respectively to being connected to water inlet pipe and outlet pipe, the first partition bottom end on the upside of septic tank ontology left and right ends It it is installed with first respectively with second partition middle-end crosses the mouth of a river and cross the mouth of a river, first lattice pond and the second lattice pond correspondingization excrement with second Pond ontology bottom end is respectively in inclined-plane to cambered surface design and corresponding cambered surface avris is installed with docking valve port, and the docking valve port passes through inner Side screw thread is connected with delivery pipe docking, and the delivery pipe is connected with the docking of the input terminal of avris water pump, and the water pump passes through screw Interlocking is fixed on right end support frame bottom side, and support frame as described above is weldingly fixed on the pedestal of bottom end.
