Description
Technical field
The utility model belongs to feedwater, sewage treatment area, relates to a kind of feedwater, sewage purification depositing reservoir of being used for, and relates in particular to the body refuse circular form depositing reservoir that suspended solid and colloid are removed in a kind of water.
Background technology
Depositing reservoir is being to use technology more widely to water treatment field.Depositing reservoir is to utilize the body refuse that gathers in the pond and the impurity particle in the former water to be in contact with one another, to adsorb, and to reach the purification structure that comparatively fast separates with clear water, can give full play to the effect of coagulant and improve clarifying efficiency.Depositing reservoir generally is divided into accelerator, waterpower circulation stirring pool, plusator and sludge blanket clarifier by action principle.Depositing reservoir is pressed the situation of body refuse, generally is divided into body refuse circulation (backflow) and body refuse suspension forms such as (filtrations).Depositing reservoir is the purification structure of comprehensive coagulation and mud-water separation process, and current are upward flow substantially.The process program of existing depositing reservoir: (1), accelerator, belong to body refuse circular form depositing reservoir, be characterized in utilizing churned mechanically castering action to finish body refuse and reflux and haptoreaction.Form by first reative cell, second reative cell and separation chamber.The mixed former water of dosing enters first reative cell, under the stirring of blade, carry out haptoreaction with circulation body refuse times over former water, be promoted to second reative cell through impeller then and continue reaction,, enter the separation chamber by diversion chamber again and carry out precipitate and separate to form bigger flco.Separation chamber's clear water zone upflow velocity is 0.0008 ~ 0.0011m/s (2.88 ~ 3.96m/h).Configuration machinery is scraped the accelerator of mud equipment can handle higher turbidity water.(2), circulatior clarifier, belong to body refuse circular form depositing reservoir, be characterized in utilizing waterpower under the effect of water sprayer, to mix and reach the body refuse circulating reflux.When the former water (behind the dosing coagulant) that has certain pressure passes through the water sprayer nozzle with high speed, around the water sprayer trunnion, form negative pressure, thereby the backflow body refuse that will be several times as much as former water sucks trunnion, and fully mix with it.Because intergranular suction-operated has been strengthened in fully the contacting of backflow body refuse and former water, reaction greatly, has quickened flocculation, to obtain clarification preferably.Consume big head, to water quality, that water temperature changes adaptability is relatively poor.Separation chamber's clear water zone upflow velocity is 0.0007 ~ 0.001m/s (2.52 ~ 3.6m/h).(3), plusator, belong to suspension body refuse type depositing reservoir, utilize the pulse decreasing water distribution method, automatically regulate the distribution of superposed layer body refuse concentration, water inlet is by some cycles water-filling and discharging water, and the superposed layer body refuse is alternately expanded and shrinks, and increases the collision touch opportunity of former particle water and body refuse, thereby the raising clarifying effect is made up of pulse generator system, water distribution steady flow system, clarification system and sludge drainage system.Former water after the dosing is the pulse mode water distribution through the effect of pulse generator.After intake chamber is full of water, in the pond, discharge water rapidly, former water sprays with high speed from the aperture of range pipe, mixes fully and initial reaction with the extremely short time under stabilier.Then by the stabilier rectification, with slow speed vertical lifting, move up and down regularly at the effect low suspension layer of " pulse " current, former water is by the collision and the absorption of superposed layer, and impurity is retained down.General 0.0007 ~ the 0.001m/s (2.52 ~ 3.6m/h) that adopts of the average upflow velocity of clear water zone.(4), sludge blanket clarifier, belong to body refuse contact separation type depositing reservoir, seldom use now.The shortcoming of prior art: the shortcoming of (1), mechanical agitation (former title machinery quickens) depositing reservoir: compare with high dense settling pond, the clear water upflow velocity is less, and the pond bulk area is big, takes up an area of big.(2), the shortcoming of circulatior clarifier: compare with high dense settling pond, the clear water upflow velocity is less, and the pond bulk area is big, takes up an area of big; Only be applicable to medium and small water factory; The consumption head is big; Sludge concentration is low, and intergranular suction-operated is poor; Adaptability to water quality and water yield variation is relatively poor.(3), plusator: compare with high dense settling pond, upflow velocity is less, and the pond bulk area is big, takes up an area of big; Sludge concentration is low, and intergranular suction-operated is poor; Adaptability to water quality and water yield variation is relatively poor.
