Abstract

The siphon decanter apparatus includes a biochemical tank with drain pipeline and pre-vacuumizing pipe, and a water sealed well beside the biochemical tank with ejector in the bottom and connected to the pre-vacuumizing pipe. The present invention has simple structure, reliable running, easy manufacture, low cost, high output water quality and other features, and is suitable for various kinds of sewage treating yard.

Description

A kind of siphon decanter

Technical field

The present invention relates to sewage disposal device, be specially adapted to a kind of siphon decanter.

Background technology

Strain hydrophone and be mainly used in the draining of SBR technology and deformation technique thereof.Safe, effective, the steady running of straining hydrophone play crucial effects for the normal operation of treatment process.According to the difference of straining the water mode, the domestic hydrophone of straining commonly used is divided into float-ball type, telescopic and hydrocone type three classes at present.Now in the SBR technology of actual motion, have that quite a few adopts be a kind of tube easy strain hydrophone, the easy hydrophone of straining of this tube is provided with water shoot and valve at reaction tank lowest water level place, valve is manual or electronic, the hydrophone of straining of this kind form has the shortcoming that water outlet band sediment influences effluent quality, and because the water shoot diameter is bigger, need to use large-diameter valves, strengthened the cost of water treating equipment; Another kind is the siphonic decant device, this siphonic decant device adopts the draining of fully buried U type pipe drainage, but it must reach the water level of setting, strain hydrophone and could begin draining, and its draining master transverse tube is to be placed at below the water surface, the deficiency that exists is easily to carry mud in the drainage procedure secretly, the defectives such as quality of the water that influence is discharged.

Summary of the invention

The object of the present invention is to provide a kind of simple in structure, reliable, easily processing, cost is low, do not carry the floating matter on mud and upper strata during draining secretly, effluent quality is good, and a kind of siphon decanter of any water level draining that can be more than minimum designated water level.

In order to overcome the deficiencies in the prior art, technical scheme of the present invention is to solve like this: comprise a biochemistry pool, the progress that its present invention gives prominence to is also to be provided with a trapped well in a side of biochemistry pool, being equipped with a transverse drainage more than the water surface of biochemistry pool is responsible for, transverse drainage is responsible for the water shoot of a band elbow and valve and is linked to each other, the water shoot top connects a vacuum-pumping tube, be connected with ejector on the vacuum-pumping tube the other end, ejector is placed at the bottom of trapped well, transverse drainage is connected with the vertical drainage arm that stretches under water on being responsible for, and the water shoot water outlet of band elbow and valve places in the trapped well.

The present invention compared with prior art, have simple in structure, reliable, processing easily, cost is low, does not carry the floating matter on mud and upper strata during draining secretly, the characteristics that effluent quality is good, adopt ejector to force to vacuumize, any water level draining that can be more than minimum designated water level, it is more easy that water displacement and water discharge time are controlled.This is strained when hydrophone is installed and need not to burrow on pool wall, and entire equipment is installed in Chi Dingshang, and ejector can conveniently be mentioned, and is easy to maintenance and operation, is widely used in all kinds of sewage works.

Description of drawings

Fig. 1 is a structural representation of the present invention.

Embodiment

Accompanying drawing is embodiments of the invention.

Below in conjunction with accompanying drawing, content of the present invention is described further:

With reference to shown in Figure 1, a kind of siphon decanter, comprise a biochemistry pool 6, one side of its biochemistry pool 6 also is provided with a trapped well 5, be equipped with a transverse drainage more than the water surface of biochemistry pool 6 and be responsible for 2, the transverse drainage person in charge 2 links to each other with the water shoot 8 of a band elbow and valve 7, water shoot 8 tops connect a vacuum-pumping tube 4, be connected with ejector 1 on vacuum-pumping tube 4 the other ends, ejector 1 is placed at the bottom of trapped well 5, transverse drainage is responsible on 2 and is connected with the vertical drainage arm 3 that stretches under water, and water shoot 8 water outlets of band elbow and valve 7 place in the trapped well 5.

Transverse drainage is responsible on 2 and is connected with two above branch drains 3 at least.

Water shoot 8 water outlets of band elbow and valve 7 place the degree of depth of the degree of depth of trapped well 5 greater than branch drain 3.

Adopt ejector to force to vacuumize, any water level draining that can be more than minimum designated water level, it is more easy that water displacement and water discharge time are controlled, this siphonic decant device is made up of a transverse drainage person in charge 2 and Duo Gen (greater than 1) branch drain 3, saved the water seal U type pipe of the siphonic decant device of prior art, the radical of vertical drainage arm 3 can be determined according to biochemistry pool water displacement size and pool size, transverse drainage is responsible on 2 and can be connected tens vertical drainage arms 3 respectively at most, and transverse drainage is responsible on 2 and can be connected several vertical drainage arms 3 at least.Straining the hydrophone principle of work is: after the aerator in the biochemistry pool stops aeration, sewage in the biochemistry pool begins precipitation, supernatant liquor appears in the upper strata of its biochemistry pool, open ejector during draining and vacuumize the formation siphon, supernatant liquor is converged to drain header 2 backs to trapped well 5 by vertical drainage arm 3 in the pond, when having arrived the water level of setting, siphon destructive, draining stops, its drain discharge is regulated by valve 7, and vertical drainage arm 3 and transverse drainage are responsible for 2 interior sediment-frees and are taken the clear water of the water allow compliance with emission standards of discharge out of, suspended substance is carried secretly less, whole device removes vertical drainage arm 3, water shoot 8 parts, vacuum-pumping tube 4 parts, ejector 1 is placed at the water China and foreign countries, and miscellaneous part all is located on the ground, substantially do not need repairing, ejector can conveniently propose the ground maintenance, when working water level is reduced to the draining stopping water level, and siphon destructive, device can stop outside draining automatically, does not need the personal management.

Embodiment 1

If the area of biochemistry pool 6 is 25 meters * 30 meters, Chi Shen is 15 meters, the transverse drainage person in charge 2 is connected with water shoot 8 with valve 7 with the band elbow, its draining pipe diameter is 500 millimeters, transverse drainage is responsible for and is connected 20 vertical drainage arms 3 on 2, vertical drainage arm 3 diameters are 25 millimeters, connect a vacuum-pumping tube 4 at water shoot 8 tops, be connected with ejector 1 on vacuum-pumping tube 4 the other ends, ejector 1 is placed at the bottom of trapped well 5, transverse drainage is responsible on 2 and is connected with the vertical drainage arm 3 that stretches under water, water shoot 8 water outlets of band elbow and valve 7 place in the trapped well 5, and water shoot 8 water outlets of band elbow and valve 7 place the degree of depth of the degree of depth of trapped well 5 greater than branch drain 3.
