Description

Concrete-form floating and filtering integrated filtering water tank

Technical Field

The utility model belongs to the technical field of sewage treatment's technique and specifically relates to a concrete form's superficial integration filtering ponds of straining, in particular to system architecture.

Background

At present, most domestic water plants generally adopt a conventional treatment process, namely, a coagulation-precipitation-filtration-disinfection process. The process can only effectively remove suspended matters, colloidal substances, bacteria, escherichia coli and the like in water, but has poor removal capability on algae and organic pollutants, particularly soluble organic pollutants, so that the safety of the water quality of the treated domestic drinking water is difficult to ensure due to the limitation of the conventional purification process under the condition that a water source is polluted, the conventional water treatment process cannot be adapted to the existing water source and water quality standard, and a new water treatment technology and corresponding system equipment must be developed.

With the continuous development of the air flotation technology and the restriction of investment cost and other aspects, the application and popularization of the air flotation technology in the aspect of water pretreatment are gradually more emphasized. The to-be-solved technical problem of the utility model is to provide a water purification effect is good, can show the superficial integration contaminated water deep treatment device that strains of concrete form that reduces the capital construction investment, solves the low turbid current situation that contains algae quality of water intractable for a long time at low temperature to exert huge effect on energy-conservation and using sparingly ground.

Disclosure of Invention

An object of the utility model is to provide a concrete form float and strain integration filtering ponds, provide a concrete form that goes out water quality of water good, save the capital construction expense float and strain integration pond, filter the integration with the air supporting, improve the treatment effeciency, save area, reduce cost.

In order to realize the purpose, the technical scheme of the utility model is that: the utility model provides a concrete form's superficial integration filtering ponds of straining, includes the concrete cell body, concrete cell body one side forms the flocculation chamber, and concrete cell body opposite side is equipped with backwash water pipeline, forms the air supporting chamber that is located the upper portion and is located the filter chamber of lower part in the concrete cell body between backwash water pipeline and the flocculation chamber, still is equipped with the mixing chamber in the concrete cell body between air supporting chamber and the flocculation chamber, be equipped with agitator and air dissolving device in the flocculation chamber, be provided with a set of vertical parallel distribution's pressure relief ware in the mixing chamber, the upper portion of air supporting chamber is equipped with a plurality of slag scrapers, and filter chamber top-down is equipped with activated carbon layer, quartz sand layer, filter plate in proper order, and above-mentioned backwash water pipeline one end is close to bottom department with the filter chamber and communicates, is equipped with.

The utility model discloses a concrete form's superficial integration filtering ponds of straining can regard as contaminated water deep treatment device, especially to the low turbid, the processing that contains algae quality of water of low temperature. The air floatation filter makes full use of respective technical advantages of the air floatation filter and the filter, and has simple structure and definite function partition. The system has the advantages of improved impact load resistance, more stable and reliable operation, superposition of the two tanks, small occupied area, shorter flow, reduction of intermediate connecting pipelines and construction investment saving. Has the advantages that: (1) the structure is compact, and the operation is flexible; (2) the occupied area is small, and the cost is saved; (3) the removal effect is good, and the efficiency is improved.

Detailed Description

The invention will be further described with reference to the accompanying drawings.

The utility model discloses a concrete form's superficial integration filtering ponds of straining, it lies in different from prior art: the concrete pool comprises a concrete pool body 1, wherein a flocculation chamber 2 is formed at one side of the concrete pool body 1, a backwashing water pipeline 3 is arranged at the other side of the concrete pool body 1, an air flotation chamber 4 positioned at the upper part and a filtering chamber 5 positioned at the lower part are formed in the concrete pool body 1 between the backwashing water pipeline 3 and the flocculation chamber 2, a mixing chamber 6 is further arranged in the concrete pool body 1 between the air flotation chamber 4 and the flocculation chamber 2, a stirrer 7 and an air dissolver 8 are arranged in the flocculation chamber 2, a group of pressure releasers 9 which are longitudinally distributed in parallel are arranged in the mixing chamber 6, a plurality of slag scrapers 10 are arranged at the upper part of the air flotation chamber 4, an activated carbon layer 11, a quartz sand layer 12 and a filtering bottom plate 13 are sequentially arranged from top to bottom in the filtering chamber 5, one end of the backwashing water pipeline 3 is communicated with the filtering chamber 5.

In specific implementation, a ceramic ring layer can be further laid on the lower portion of the quartz sand layer 12, the ceramic rings laid on the ceramic ring layer are hexagonal ceramic rings, a cylindrical volcanic rock pillar is embedded in the center of each hexagonal ceramic ring, and the volcanic rock pillar is processed from natural eruption rock and is embedded in each hexagonal ceramic ring. The composite filter material can improve the purification effect in a limited plane space.

When the device is specifically implemented, water entering the flocculation chamber is combined with micro-bubbles in the mixing chamber under the action of the stirrer and the dissolved air release device, enters the air flotation chamber, scum is scraped by the scum scraper, then the treated water passes through the filtering unit downwards, the filtering unit sequentially comprises an active carbon filtering layer, a quartz sand filtering layer and a filtering bottom plate from top to bottom, and the bottom of the unit is communicated with a water backwashing pipeline and a filtering water pipeline. The flocculation chamber aims to aggregate particles with flocculation performance in mutual contact to form larger alum flocs which are easier to settle; the stirrer is adopted to ensure that the particles are fully contacted, so as to be beneficial to subsequent further treatment; the air dissolver and the pressure releaser are used for continuously dissolving air into water under certain pressure and then releasing the air through the releaser under reduced pressure to enable the air dissolved into the water to form a large amount of micro-bubbles; the micro-bubbles in the air floatation tank and the flocculating agent are adhered to each other and float on the water together to form scum; the slag scraper is used for removing scum generated in the air floatation tank; the filtering part is designed into a carbon sand double-layer filtering mode, the content of dissolved oxygen in water is increased due to the air floatation unit, and meanwhile, because the activated carbon has the characteristic of large specific surface area, a biological film is easy to grow on the surface of the activated carbon in long-term operation, and a good removing effect is achieved on organic matters; and the quartz sand on the lower layer can effectively remove the fallen biological membrane, thereby providing guarantee for the water quality of the filtered water.

The foregoing is a more detailed description of the invention, taken in conjunction with the accompanying preferred embodiments, and it is not intended that the invention be limited to the specific embodiments described above. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses a protection scope.
