Description

Combined simple flocculation sedimentation device

Technical field

The utility model relates to a kind of sewage disposal device, is a kind of combined simple flocculation sedimentation device specifically, belongs to environmental technology field.

Background technology

Small-scale sewage discharge often appears for life or in producing, particularly away from the place of municipal pipeline, small-sized Sewage treatment systems need be set carry out the processing of sewage, make it allow compliance with emission standards, so that discharging on the spot, the small-scale Sewage treatment systems of this class is because treatment capacity is little, the investment that can bear is little, therefore need a kind of wide adaptability, finished product that cost is lower, so that, and need not carry out independent design and engineering construction at various concrete sewage character at the unified finished product of plant produced.In view of having such pollutent usually in the sewage: therefore BOD and COD that suspended substances such as throw outs such as floating matters such as greasy dirt, sand and dust, colloid, microorganism and organic pollutant constitute need this general-purpose equipment to have the ability of eliminating these pollutents.

But, because the sewage quantity difference of different sewage source emission, single Sewage treatment systems cannot be adapted to the sewage disposal in various sewage discharges source, and the Sewage treatment systems of producing various different sizes in advance not only needs cost bigger in design and production, and can also difference can be arranged for the treatment process of different sewage, the adaptability of the treatment facility that designs so in advance and produce will go wrong.Therefore; be the economy and the technical superiority of accomplishing scale production and designing; be necessary to develop the treatment unit of the modular same specification that is suitable for being combined into various different treatment flow processs and different treatment scale,, can be arbitrarily made with different treatment systems by the device of these standard specificationss.

The utility model content

For overcoming the above-mentioned defective of prior art, the utility model provides a kind of combined simple flocculation sedimentation device, and this device adopts standardized casing, can arbitrary combination, build up different treatment systems.

The utility model realizes that the technical scheme of above-mentioned purpose is: a kind of combined simple flocculation sedimentation device, the simple flocculation sedimentation tank that comprises a plurality of employing stdn casings, described each flocculation sedimentation tank is parallel with one another, described casing is rectangular, its two ends respectively are provided with three identical connection short tubes that have flange of upper, middle and lower, described casing top is provided with agitator, mix medicinal cupping and volume pump, the stirring rake of described agitator extends in the described casing, the outlet of described mixed medicinal cupping connects described volume pump import, the output tube of described volume pump extends to the intravital nearly water inlet of described case, connecting short tube in one of described casing is water outlet, the following connection short tube of described casing front end is a water-in, the following connection short tube of rear end is the throw out outlet, and described bottom half is provided with the device of skimming.

Because the utility model has adopted standardized casing, this casing is provided with standardized connection short tube, therefore can couple together easily by flange connection with the stdn casing of same size, realize different treatment capacity and processing parameter, adapt to different processing requirements, for example when needs enlarge treatment capacity, can adopt a plurality of casings mode parallel with one another, when needs prolong treatment time or flow process, can adopt the mutual placed in-line mode of a plurality of casings, form thus and have the treatment system of different treatment ability and processing parameter, and also can adopt in a like fashion and be connected with the back order processing apparatus with other preorders, form the treatment system of whole process; Owing to adopted standardized flange connection, made to interconnect to become very convenient; Owing to be provided with three water outlets of upper, middle and lower and water intake mode, can realize different current forms; Owing to adopted rectangular box, can more effectively utilize the place, under the situation of same treatment ability, reduce the place occupancy to greatest extent; Because total system is that independent case body is formed one by one, when the intravital processing of each case all reaches good result, can guarantee the good treatment effect of total system, avoid the error that may occur because of independent design.And the standardization device that this standardized casing and employing stdn casing are made, its production also becomes very simple, as long as a kind of design and processes equipment has greatly been simplified production process and production cost.
