Description
The present invention relates to a kind for the treatment of pond of from waste water, removing suspended particle, relate in particular to the treating pond of from waste water, removing phosphatic suspended particle.
This treating pond is the integral part of refining plant.
Handling the refining plant of family domestic waste water, provincialism waste water and trade effluent is known by people already.Most of refining plants are hard-wired, and waste water enters biological treatment stage then earlier through preliminary cleaning usually, after the after processing.After is handled on the one hand and the biological sludge in the treating processes can be precipitated, but post-processing stages also can make the phosphoric acid salt delayed precipitation in the waste water, in this case, should add precipitation agent so that calcium phosphate precipitation in the outlet in after pond.For this reason, essential addition reaction pond and aftertreatment pond.During delayed precipitation, the superfine activity that also contains the waste water of the biopurification of hanging oneself is simultaneously polluted mud throw out and other suspended substances, therefore, the concentration of phosphorus can be dropped to below the 1mg/l.
With regard to the biological treatment of the top waste water of mentioning, can adopt different means and method, and most popular method is activated sludge process and solid method.
As mentioned above, the shortcoming of existing refining plant is must realize settling step separately with corresponding treating pond in order to remove phosphoric acid salt.
The objective of the invention is to improve the efficient of refining plant, especially make the best results of removing suspended particle in the waste water.
In order to finish above-mentioned task, starting point of the present invention is as follows: utilize one group of bacterium, by " improving phosphatic absorption " above-mentioned phosphorous hydrochlorate phosphoric acid salt storage vessel seldom is not set.For this reason, the phosphate source that the phosphate component separated into two parts in the waste water can separately be treated.Part phosphoric acid salt is included in the excess sludge of biopurification level, can this portion phosphate be removed by the after pond; Another part phosphoric acid salt, promptly from that part of phosphoric acid salt of above-mentioned bacterium (microorganism) " energy " then with this kind method deposition, because they are present in the suspended substance with the phosphate particle of minimum.In addition, other particles also are present in the waste water as suspended substance.
Therefore, the treating pond of pointing out to be used for to remove the suspended particle of waste water in general embodiment of the present invention should have following characteristics:
In the bottom side strainer that can allow waste water flow through is installed at least, is made waste water flow through this strainer, thereby can remove by means of (phosphatic) suspended particle that strainer will have been mentioned;
Place the downside of strainer, the effect of above-mentioned ventilation member to be one or more ventilation members, by means of with the above-mentioned strainer of the air scour of waste water countercurrent flow, the notion of " air " also comprises other gases, for example oxygen herein;
Each ventilation member has a discharge stream to cross the discharge line of the waste water of strainer, in other words, flows through strainer and the waste water that purified is collected in the ventilation member of strainer bottom, and is drained;
A valve has been installed on each ventilation member, and this valve can make waste water stop to flow or letting alone unrestricted flow;
In addition, induction pipe is housed on ventilation member;
Above-mentioned induction pipe connects by following mode, makes one to close wastewater valve, and air just flows into ventilation member, flow through strainer then, therefore, alternately make the waste water that flows through strainer flow into ventilation member and drain, perhaps import air and come back-flushing filter from ventilation member through ventilation member.
A device is housed, so that drain throw out and/or the solid particulate of alluvial on strainer above strainer.This device also can be drained the mud of alluvial on strainer, under this device also can will wash from strainer behind the air back-flushing filter simultaneously, perhaps be that the particle that lumpd is discharged treating pond.
From top description as can be known, the present invention can save the addition reaction pond of a precipitate phosphoric acid salt, and or rather, after pond (settling tank) can be simultaneously as removing phosphoric acid salt and other suspended particle.
Because the strainer/ventilation member in the treating pond can be integral setting, thereby when reducing laid down cost, can make the effect of purifying liquid waste be higher than mean level (ML).
In one embodiment of the invention, ventilation member is laid on the whole downside of strainer.Can become single parts according to big young pathbreaker's filter design in refining plant and after pond or form by several sections.Such as already known, adopt the porcelain filter particularly advantageous.
In addition, can be directly installed on the downside of strainer, the waste water that flows through strainer is all received by ventilation member according to the one or more ventilation members of big young pathbreaker of the filter surfaces that is constituted.Ventilation member for example can be trumpet-shaped metal parts, and its cross section can be square or rectangle, and adjacent component is close to each other.Can be fixed on the strainer with method in various manners.For example, ventilation member can be pasted or is glued to mortar in the corresponding groove of strainer.Certainly, ventilation member removably is fixed on the strainer also within the scope of the invention.Even ventilation member can be installed in the zone that the treating pond bottom water flows through.
Because ventilation member is top described horn-like, the geometrical shape of vent pipe is also definite, and the simplest situation is that vent pipe is arranged vertically downward, and like this, the vent pipe of each ventilation member can be connected on the house steward.
In order to need corresponding valvegear discharging and ventilate alternately conversion between two kinds of operations.The simplest situation is that an induction pipe that separates with vent pipe is connected on the ventilation member.In this case, the valve that can change all is housed on the two tubes between opening or closing.
According to a kind of structure of especially simply implementing, can adorn a T-valve, at this moment, induction pipe joins in valve district and vent pipe.In this case, induction pipe for example is arranged horizontally, and it and vertical (vertically arranged) vent pipe join.
Only miscellaneous part is used as waste discharge also within the scope of the invention with a ventilation member blowing air.
The device that is used for waste discharge mud for example can be a so-called banded eradicator.What mention is the device with side two cycle operation bands on cylinder herein, and a side freedom of band is sagging, is provided with some battens between cylinder, and batten was scraped the upper surface of strainer, thereby the solid particulate that will deposit on strainer is taken away.
In order to guarantee that clearing device can remove solid particulate reliably, in another embodiment of the present invention, it is protruded in outside the strainer in the side, a device that takes out solid particulate (comprising precipitating sludge) is set below this device protuberance., the treating pond in this scope partly can be built up for this reason, have in the conveying end, can take out solid particulate through this mouthful in its lower-most point as tubaeform tapered down shape.
In addition, above-mentioned treating pond also can have other functions, and by this idea, the present invention's suggestion is fixed bed of the complete outfit for the treatment of pond or fixed bed feeder.
In other words, can in known manner with in the waste water space of method on strainer one or more fixed bed bodies or a kind of filler of packing into be set.
In this case, the after device has just become biologic chain (autarke biologische) refining plant with requisite after function.
As previously mentioned, precipitation be taken away and be sent to biogenic sediment that forms on fixed bed and the excess sludge that produces therefrom for example can by banded eradicator.In addition equally as previously mentioned, waste water is by the strainer after.Not only can recoil (cleaning) waste water oxygen supply that simultaneously can also be in treating pond to strainer by means of subsequently aeration.
Because intermittently ventilation, thereby can carry out nitrated/denitrification simultaneously.The required oxygen of nitrification imports in the waste water by ventilation member (during back-flushing filter).Reductive N-compound oxidation is opposite during with nitrification, and when denitrification, the nitrogen compound of oxidation (nitrate, nitride) is reduced to nitrogen element (N
2).
Denitration (just by microbial respiratory nitrate) can be carried out when stuffiness.
According to the present invention, in denitration, filter, in other words, waste water is by after, simultaneously also by denitration when stuffiness.
Obviously, in this way, can adopt the waste water purification device of a strainer compactness, that have one when after waste water, this device is compared with traditional refining plant, and not only structure is extremely simple, and takes up little room, and cost is very low.The manufacturing of device is also simpler, because can save a supercharging device herein, and must use supercharging device for waste water being imported the after pond in the prior art.Therefore, in device of the present invention, waste water flows through strainer with hydrostatic pressure basically.
