Abstract

The utility model relates to water treatment equipment, in particular to W-shaped variable flow speed contact flocculation high efficient composite sloping plate precipitation equipment which belongs to the technical field of solid-liquid separation equipment and relates to the technical improvement of water treatment precipitation equipment. After a period of time running of the sloping plate precipitation pool adopted at present, the treatment efficiency and the treated water quality are decreased obviously. The main cause is as follows: the water flow state in the sloping plate causes disturbance against the precipitation to be small, light, and crushed flocculation particles, thereby being not separated effectively. In order to solve the problem, the W-shaped variable flow speed contact flocculation high efficient composite sloping plate which can enhance the precipitation effect and the load is provided by the W-shaped variable flow speed contact flocculation high efficient composite sloping plate precipitation equipment through utilizing the principle of backward flow contact flocculation. The W-shaped variable flow speed contact flocculation high efficient composite sloping plate precipitation equipment is characterized in that ribs are fixed on the sloping plate of the water treatment equipment, each rib is arranged in a W shape way and is fixed at the lower part or the whole part of the sloping plate, thereby being able to reduce the turbidity of treated water and further enhancing the precipitation separation efficiency.

Description

The efficient compound sloping plate deposition equipment of W deformation flow velocity contact flocculation

Technical field:

The utility model belongs to the solid-liquid separating equipment technical field, relates to a kind of improvement of water treatment facilities technology.

Background technology:

Precipitation is the important step of Separation of Solid and Liquid in the water treatment technology, its operation conditions directly influences effluent quality, the process form that adopts in water treatment at present mainly contains horizontal sedimentation tank, swash plate and tube settler etc., wherein tube settler is most effective, but in practical application in recent years, find, tube settler is after operation a period of time, and treatment effeciency and effluent quality obviously descend, and reliability can not show a candle to horizontal sedimentation tank.

The reason that causes said circumstances mainly is because traditional sedimentation theory thinks that current are to be in laminar condition in swash plate, the tube settler, actually this is not so, current have pulsation in tube settler, when alumina blossom particles big in the inclined tube in precipitation with the water generates relative motion, can produce micro cyclone in the alumina blossom particles back, thereby caused the pulsation of current, these pulsation do not have influence for the precipitation of big alumina blossom particles, but play the jacking effect for the incomplete short grained precipitation of reaction, will influence the water quality situation of water outlet.

The principal element that influences sedimentation basin final outflow water quality is that can little, light, broken flocculation alumina blossom particles effectively be dammed in settling apparatus, if can allow these little, light, broken flocculation alumina blossom particles in settling apparatus, be coupled to bigger particle by contact flocculation, then effectively dammed easily, thereby raising sedimentation effect, improve effluent quality, this point has been that a large amount of research institutes confirm.

Technology contents:

In order to address the above problem, suppress the pulsation of current, the utility model utilizes the counter-current contact flocculating principle, provides a kind of and can reach the efficient compound swash plate of W deformation flow velocity contact flocculation that improves sedimentation effect and load.

Be fixed with rib on the swash plate in water treatment facilities, each rib is the W shape bottom that is fixed on swash plate arranged evenly or all, each swash plate is the rectangular slab face.

The utility model has been strengthened the compound action of the contact flocculation of swash plate, and by the change place's cross-section of river that becomes a mandarin, the local flow velocity that changes is given full play to the contact flocculation effect of swash plate and removed the incomplete granule of reaction, thereby can further reduce delivery turbidity; Equipment will have the mechanism of precipitation and clarification, can improve the surface loading of sedimentation basin; Compare with depositing reservoir, do not need suspension slime layer for a long time to form the phase, liquid-flow state is stable, and slime layer forms stable, and initial operating stage can reach desirable treatment effect; Because the acting in conjunction of suspension slime layer and sloping plate deposition is fine to the adaptability of different quality and impact load; The density of the heavy mud of sedimentation basin is bigger than conventional sedimentation basin, and spoil disposal water can have the saving about 50%, but the conserve water resource reduces running expense.

Therefore, of the present invention applying will have remarkable social benefit and economic benefit.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is described further:

As can be known, swash plate is the important component part of Separation of Solid and Liquid from water treatment facilities sedimentation basin figure, is fixed with rib on swash plate, the one, and the intensity of reinforcement swash plate can change the nowed forming of handling water in addition, makes the particle in the water quicken flocculation sediment.

Handle water by sedimentation basin water distribution section, upward flow is gone into this equipment, sediment space through swash plate and rib composition, liquid juice flows out, solid particle grows up to certain yardstick, under the gravity effect under the physics chemical action of formed suspension slime layer in sediment space, break away from precipitation unit, sink to the sedimentation basin bottom; Rib here plays when supporting the swash plate effect, is also adjusting the cross section of precipitation unit, and the glide slope of part body refuse is provided; When the particle inflow in the upward flow processing water has the precipitation unit at certain inclination angle with gravity direction, particle is deposited to the swash plate upper surface under the effect of gravity, and glide along the surface of swash plate, meet the jacking effect of upward flow, will be under the effect of waterpower lift, along with current are gone up together to motion, and repetition precipitation process, in the meantime, because the sediment space at swash plate and rib has a large amount of particles to repeat above-mentioned motion, exist complex interactions between particle and form the suspension slime layer, particle is in precipitation process, and the effect of the power on existence and swash plate surface has only the density of particle and yardstick to reach certain numerical value simultaneously, could break away from precipitation unit, be deposited to the bottom of sedimentation basin; Particle in the fluid obtains removing by comprehensive physics chemical action such as contact flocculation effect and gravitational settlings; And, finally can obtain the clear liquid of high-quality because the clarification of suspension slime layer goes out to flow to influence in the supernatant small-particle of quality quantity and will obtain removing.
