Description
Technical field
The present invention is a kind of method and apparatus of environmental protection, and mud method and apparatus is inhaled in the transmission that especially configures air lift unit.
Background technology
Sedimentation basin, by residing position in sewage disposal flow process, can be divided into two kinds of primary sedimentation pond and secondary sedimentation tanks.Primary sedimentation pond operated by rotary motion is after the setting pot of sewage treatment plant, before aeration tank, after secondary sedimentation tank is arranged on aeration tank, before advanced treating or discharge.Second pond is the important component part of activated Sludge System, and its effect is mainly to make mud separated, makes mixed liquor clarification, concentrated and returnedactivatedsludge.Sewage is after biological treatment, must enter second pond and carry out mud-water separation, processing water up to standard after clarification could discharge, simultaneously also will be for biological treatment facility provides certain density returned sludge or a certain amount of processing water, so the service behaviour of second pond has direct relation to the operational effect of activated Sludge System.
Peripheral-traction formula suction dredge is generally the main equipment of second pond configuration, in Sewage Treatment Project, application is wider, it uses function to be mainly the mud-water separation in second pond, conventionally by the suction arranging in second pond, scraping mud equipment collects, collect sludge part and supplement biochemistry pool sludge quantity by backflow, the unnecessary mud of part is delivered to sludge treating system and disposes.
Second pond is usually designed to circle, distinguishes have " middle part water inlet peripheral effluent formula " and " circumferential water feed peripheral effluent formula " structure by sludge discharge way." circumferential water feed peripheral effluent formula " pond body is usually designed to conical bottom, by scraper plate center, concentrates mud to be extracted out by dredge pump, but because of civil engineering structure complexity and construction cost is high and cannot guarantee the uniformity of circumferential water feed, generally applies less.Most of second pond is " middle part water inlet peripheral effluent formula ", mud extraction has and mud collection area is set at the bottom of pond and directly pumps out and pass through liquid level mud-collecting slot suction collection mud and discharge mode, more from result of use and range of application the latter, major applications is peripheral-traction suction dredge.
Peripheral-traction suction dredge mainly by driving mechanism, girder, central rotation bearing, guide shell, scrape mud system, deslagging bucket and flushing machine, radial type and scrape slag rake, skimming plate, skimming bucket, water outlet triangle and form along parts such as plate, scum board, control cabinets.Its suction mud structure is the effectively core component of running of equipment, by structure, general employing configuration sludge pump is set or utilizes liquid level difference by bottom to pond interior conduit spoil disposal.Sludge pump is inhaled the applicable various mud operating modes of mud mode, still has effect, but exist equipment operate power large to accumulating mud, and energy consumption is high, and another dredge pump is positioned at below liquid level, and maintenance is changed and all had greatly difficulty, and equipment performance driving economy is poor; Utilize liquid level difference spoil disposal, applicable in the little perfect condition of sludge quantity, but to a large amount of mud with accumulate mud almost without suction capactity, can only take clearly the modes such as pond, applicability is poor.This is the current ubiquitous performance deficiency of peripheral-traction suction dredge.
Summary of the invention
The object of the invention is, for existing peripheral-traction suction dredge a little less than inhaling mud ability, large or the inactive defect of depositing mud non-processor means to the long-pending sludge quantity of second pond, a kind of Novel peripheral drive suction dredge is proposed, especially be equipped with air-lift device peripheral-traction suction dredge, form a kind of novel device, greatly promote mud and put forward energy-absorbing power and can meet the instructions for use under various operating modes.
In order to solve the technical problem of traditional suction dredge, the present invention adopts following technical scheme:
