CN2873748Y - Poisonous and harmful waste water filter grid - Google Patents

Abstract

The utility model is mainly applied to harmful sewerage and the low-quality conditioning water discharged by the present domestic chemical plants, dye printings, paper-makings, galvanizations, leathers, fertilizers and medicine-makings or the like. Before the sewerage is discharged, one filter made of cotton resists a certain particulate pollution, and the other filter made of adsorbing material activated carbon fiber adsorbs the harmful sewerage as much as possible to achieve the discharge criterion. In this way, the utility model can reduce the harm to the creature and the pollution to the environment.

Description

Poisonous and harmful sewage water filtration grid

Technical field

The utility model is to adopt high absorption novel absorbent charcoal fibrefelt, enterprises such as each chemical enterprise, printing and dyeing, papermaking, plating, leather, chemical fertilizer, pharmacy are discharged a large amount of poisonous and harmful sewage and Sewage Plant sewage after treatment, carry out all efficient adsorption filtration of hazardous and noxious substances molecule.The treatment process in past, most not good enough to various organic and inorganic compound effects soluble in water.Adopt the methods such as decomposition, neutralization of chemistry, also only can solve several objectionable impuritiess, and eliminate a kind of harm and increased other pollution again, to hundreds of objectionable impurities in the water, an utterly inadequate amount.And the absorption of employing activated carbon fiber felt, it is a physical process, because a large amount of very long capillary holes (20  left and right sides holes are about 83.9%) are arranged on the every fiber, when current through out-of-date, produce the micropore effect, will divide muon capture (enterprise can reclaim according to emission of substance) hazardous and noxious substances of all processes, their unlikely being discharged in the great rivers are gone.

Background technology

Domestic each chemical enterprise, printing and dyeing, papermaking, plating, leather, chemical fertilizer, pharmacy etc., all can produce a large amount of waste water, sewage every day, costly owing to dispose of sewage, the enterprise that has has to throw huge fund and sets up sewage disposal device, but running efficiency is not high, steals sewer in the same old way, cause national great rivers quality of river water to descend, a lot of animals and plants grow simultaneously a lot of new virus and bacteria and mutation again in some section extinctions, endanger vast biology.

Because activated carbon fiber has very big specific surface area (1000m ²～1600m ²/ g), very big pore volume and certain pore size distribution (accounting for 83.9% about 20 ), just because of it has this constructional feature, make it than " smoke mask " middle charcoal absorption amount of using is big tens times now, to virus and bacteria, microorganism, various hazardous and noxious substances molecules, organic compound etc. all have very high absorption capacity.The 2nd, high two to three orders of magnitude of adsorption rate specific activity charcoal.The 3rd, desorption is fast, gets final product desorption half an hour as handling with 120 ℃～150 ℃ hot-air dries.Behind over thousands of suction, the desorption, its absorption property is constant, and is reusable, reduces cost.The 4th, heat-resisting, acidproof, alkaline-resisting chemical stability is good, does not produce secondary pollution.

We filter the last step that this high and new technology material is applied in each sewage discharge enterprise and Sewage Plant, just can improve the quality and the rank of sewage effluent greatly, the also recyclable part useful matter of manufacturer reduces cost, environmental cause, favourable human health.

Summary of the invention

The utility model to being dissolved in the various hazardous and noxious substances in the sewage, does not have whole absorption of selecting for solving each blowdown enterprise and each sewage work, improves the effluent sewerage grade, reduces the pollution to the nature environment.

The utility model is to address the above problem the technical scheme that is proposed to be: the sewage after several different methods is handled, be pooled at last in the accumulation pond, and in the accumulation pond, add the twice filter grid again.Before together be the filter grid of forming by space wadding etc., to stop the pollutent of certain particle size.The back is the filter grid of being made up of the activated carbon fiber felt together, adsorbs various hazardous and noxious substances soluble in water.

Each filter grid is 1m * 1.5m rectangle stainless steel tank bracket (other shape also can) 1 in principle.There is closeer Stainless Steel Cloth 2 on both sides.Accompany multilayer activated carbon fiber felt 3 in the centre of two veils, overlapping thickness is 2cm～5cm (overlapping thickness will be regulated according to sewage pollution degree and effluent sewerage index).The activated carbon fiber felt lamination that clips and the Stainless Steel Cloth on both sides, be fastened on the stainless steel frame with stainless steel bolt.The space wadding filtering net is also made like this.In the middle of sewage accumulation pond, traverse and set up two to filter screen by stainless steel and forms insert and tackle wall, all sewage that dispatch from the factory are all essential through this twice filter grid filtration, every filter grid inserts all to arrange on the body of wall two chutes, when need clean desorption, can insert standby filter grid framework earlier and enter another chute, reintroducing needs cleaning, desorption framework.According to the size in accumulation pond, these two are filtered hoarding and can build several square metres to tens square metres.The flow velocity of filter grid water of flowing through is difficult for too fast, if water flow velocity is bigger than normal, can strengthen the flow area, lowers flow velocity, improves filtration efficiency.As it is higher to detect the effluent sewerage laboratory indexes, can increase activated carbon fiber felt thickness, reduce flow velocity or increase and filter progression, but equal qualified discharge.

Specific implementation method

Embodiment includes stainless steel frame 1 as shown in Figure 1, and both sides are clamping activated carbon fiber felt lamination 3 (or space wadding laminations) in the middle of Stainless Steel Cloth 2, two nets, are fastened on the framework 1 with stainless steel bolt.

Middle traversing separates support or the pillar that two rows can insert some filter grid frameworks respectively in the accumulation pond, and each chute all can insert two filter grid frameworks side by side, is convenient to replacing, cleaning, desorption.In groove, be equipped with elastic sealing gasket, make the water can only be by discharging behind the filter grid.

Claims (1)

1. A kind of further clarifying urban sewage and indusrial toxic harmful sewage water filtration grid, include stainless steel frame (1), Stainless Steel Cloth (2), space wadding or activated carbon fiber felt (3), reach the CARBURIZING FURNACE FOR STAINLESS FASTENER that the three is fixed together, it is characterized in that in the middle of two-layer Stainless Steel Cloth, accompanying respectively space wadding and multilayer activated carbon fiber felt (3).
