The beneficial effects of the utility model are to handle the high density salt-containing organic wastewater effectively, and the saltiness that purifies the treating water of back discharging can be below 0.01%; And processing cost is low, is easy to apply.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

The utility model is described in further detail below in conjunction with embodiment shown in the drawings:

As shown in the figure, waste water enters tube mixer 11 after removing big solid waste through grid 12, and sewage is carrying out mud-water separation through entering in the mud-water separation pond 13 after the mixing effect of tube mixer 11 by coagulating sedimentation.At grid 12 dosing coagulant PAC (polymerize aluminum chloride) to the sewage at position between the tube mixer, enter in the sewage at position between the pond to the mud-water separation at tube mixer and to add coagulant aids PAM (polyacrylamide).After the separation of pond, water outlet is (respectively by connecting water pipe A, B, C, D, E, F) flow through adjusting oxygen compatibility pool 1, one-level contact-oxidation pool 2, one-level settling tank 3, oxygen compatibility pool 4, two-stage biological contact oxidation pond 5, second-level settling pond 6 successively one by one in mud-water separation for waste water.Combined stuffing 21 and combined stuffing 52 are installed in aerator 22 and 51 oxygenation that two contact-oxidation pools 2 and 5 are all formed by blower fan and airduct respectively in the pond, agitator 41 also is set in the oxygen compatibility pool 4 stirs.Waste water carries out solid-liquid separation through behind a series of biochemical actions in settling tank 3 and 6, mud is sent into sludge sump 9 by sludge pump 7 in the settling tank, and part mud is back to regulates oxygen compatibility pool 1 and oxygen compatibility pool 4; Mud is after sludge pumping is gone into 10 processing of sheet frame pressure filter in the sludge sump 9, and mud cake is transported outward.

Principle of work of the present utility model is: after waste water is removed bigger solid waste through grid 12, water outlet enters tube mixer 11, dosing coagulant PAC in the outlet conduit before entering tube mixer 11, make the sufficient coagulation of sewage, water outlet through coagulation adds coagulant aids PAM before the pond 13 in flowing into mud-water separation, under the effect of PAM, the flco volume increases nature and sinks, the mud that deposits is sent into sludge sump 9 by pipeline by pump 8, supernatant liquor is excessive to regulating in the oxygen compatibility pool 1, is implemented in the purpose of carrying out mud-water separation in the mud-water separation in the pond 13.Pond 13 water outlets enter and regulate oxygen compatibility pool 1 in the mud-water separation, sewage is subjected to the dual function of regulating effect and microbiological deterioration at this, organism obtains the part degraded in the sewage, and improved the biodegradability of sewage, its water outlet enters the one-level contact-oxidation pool, and organism is attached on combined stuffing in the waste water microbial film absorption and oxygenolysis become CO ₂And H ₂O, 2 water outlets of one-level contact-oxidation pool enter settling tank 3 with the microbial film that comes off and carry out mud-water separation.Settling tank 3 adopts the higher settling tank that has solid-liquid separation inclined tube 31 of surface load, settling tank 3 water outlets enter oxygen compatibility pool 4, by microorganism in the oxygen compatibility pool 4 organism of difficult degradation is further degraded, continue to improve wastewater biodegradability, oxygen compatibility pool 4 water outlets enter two-stage biological contact oxidation pond 5, organism obtains continuing degraded by biomembranous effect in the waste water, finishes organic a large amount of removals.Settling tank 6 also adopts the higher settling tank that has solid-liquid separation inclined tube 61 of surface load, but settling tank 6 water outlet qualified discharges.

The available concrete of the construction in each pond is selected acclive plot, keeps reasonable drop according to adjacent two ponds of geographical environment, is convenient to gravity flow.The arrangement that should make the lift pump water lift that geographical conditions are not inconsistent.

The equal buyable of former device that the utility model is all; Wherein grid is by the production and sales of Zhucheng, Shandong market day Dong Beite environmental protection equipment company limited, tube mixer is the prosperous outstanding environmental engineering equipment of a Jiangsu Qidong City company limited production and selling, pond self-control in the mud-water separation, can make cylindric by stainless steel or glass reinforced plastic, the bucket shape mouth of spoil disposal water is established in the bottom, upper opening enlarges, filler is the combined stuffing of φ 150, good and the environment-friendly filler company limited production and selling by Yixing City, stirrer is by the safe profit of Yixing City environmental protection equipment company limited production and selling, inclined tube is the plastics inclined tube of φ 75mm, by the Zhejiang Yuhuan county prosperous water treating equipment of gold factory production and selling, plate-and-frame filter press is by Hangzhou dragon's pool pressure filter company limited production and selling.
