Description

Vacuum water decanter

Technical field

The utility model relates to sewage-treatment plants, specially vacuum water decanter.

Background technique

With the rapid economic development in our country, pollution on the environment is increasingly deepened, therefore the dirt that all trades and professions generate Water also dramatically increases, and the processing task of municipal sewage plant is caused constantly to aggravate.Activated sludge process is to sanitary sewage, city There is very big advantage in terms of the processing function of city's sewage and Organic industrial wastewater, except having good degradation to organic pollutant Outside function, also there is preferable effect in terms of biological denitrificaion, dephosphorization, in addition to this, activated sludge process system composition and operation Flexibly, various, operating cost is low, therefore becomes the preferred processing technique of municipal sewage, organic industrial sewage.Common activity is dirty Bricklayer's's skill includes AO technique, A²O technique, oxidation Ditch Technology, sequencing batch activated sludge (SBR) technique etc..Wherein SBR is an inter-species The activated Sludge System for formula of having a rest, essential characteristic are that biochemical reaction, the separation of solid and liquid, row of sewage are realized in a reaction tank Water, spoil disposal.Therefore, only one reactor of SBR technique, does not need secondary settling tank, does not need sludge reflux equipment, under normal circumstances Conditioning tank is not needed, 30% or more capital expenditure, and characteristics of compact layout is saved than conventional activated sludge process, saves land occupation yet. In addition, SBR process effect is good, has good dephosphorization and denitrification effect, sludge settling property good and can well adapt into water Water, variation water quality can realize continuous flow by double ponds or more pond combined runnings, be one kind in municipal sewage, You Jigong Widely used activated sludge process in terms of industry wastewater treatment.Water decanter, be most critical in SBR technique mechanical equipment it One, it has and can drain primary water from static pool surface, precipitates without stirring, it is ensured that the effect of effluent quality.

Water decanter is many kinds of, can be divided into mechanical, hydrocone type, self-floating etc. by its structure type, at present domestic application Extensive is mostly rotary (one kind for belonging to mechanical water decanter), but there are some defects for these water decanters: 1, SBR is to straining water The requirement of device is very high, requires when draining not stirring precipitating sludge layer and to the more demanding of robot control system(RCS)；2, water decanter is automatically controlled The mechanical part of valve and mechanical water decanter is often easily damaged, and slightly failure cannot be run, and is often had and is run mud phenomenon, and Maintenance is complicated；3, water decanter water head-drop is lower, is affected to the elevation of subsequent treatment process, and needing to increase buried depth could protect Card gravity flow enters, and needs setting intermediate pool further to be promoted if subsequent treatment process is filter device etc., increases energy consumption；4, Due to not setting primary sedimentation tank, it is also easy to produce dross, scum problem is not yet properly settled.

Therefore, it is simple to design a kind of structure, maintenance is easy, and water head-drop is high, and the water decanter for being not likely to produce dross is Very it is necessary to.

Summary of the invention

The utility model solves existing water decanter and easily disturbs precipitating sludge layer, requires height to robot control system(RCS), maintenance is multiple The problem of miscellaneous, mud phenomenon is run in easily appearance, and fluctuation of service, water head-drop is low, is also easy to produce dross, provides a kind of vacuum water decanter.

The utility model is achieved through the following technical solutions: vacuum water decanter, closed true including what is be vertically arranged Empty drainage tank is installed with the suction hose that vacuum diversion volume is stretched out in lower end in the vacuum diversion volume, and the suction hose upper end is protruded into very In empty drainage tank, and with the upper top surface inside vacuum diversion volume there are water suction be spaced, the vacuum water diversion pot sidewall be provided with The opposite liquid level observation window of suction hose upper end, top surface is provided with exhaust valve port on the vacuum diversion volume；The suction hose lower end Head is provided with water suction horn mouth, and the water suction horn mouth is connected with and is absorbed water by dowel, and there are between centainly for horn mouth lower end Every horizontally disposed water suction mud guard；The vacuum diversion volume penetrates through on the side wall of bottom and is connected with water pump suction pipe, The pump sump pipe end is connected with centrifugal pump, is also connected with pumping line between the centrifugal pump and water pump suction pipe. Centrifugal pump will be vacuumized by water pump suction pipe in vacuum diversion volume.The water suction horn mouth of suction hose lower end extends to liquid level or less and takes out The clear water mentioned in sbr reactor pond enters in vacuum diversion volume, and specific gravity is greater than water by the water suction mud guard of water suction horn mouth end Most solid waste stop, it is stopped to enter in vacuum diversion volume, and clear water enters around water suction mud guard from surrounding In suction hose, meanwhile, it is smaller to being disturbed in sbr reactor pond when water suction mud guard can ensure that vacuum extraction clear water, avoid disturbance heavy Shallow lake sludge blanket.Vacuum water diversion pot sidewall is equipped with liquid level observation window, in extracting, vacuum water diversion tank level is prevented to be higher than suction hose Upper end, water reverse irrigation flow back into sbr reactor pond.Vacuum water diversion tank top sets exhaust valve port, when needing water in drain tank, beats Begin to rehearse valve port while, and the inside and outside connection of tank, air pressure is consistent, and water can be emptied by water pump suction pipe, pumping line in tank.

The utility model has the advantage that 1, water outlet is high-efficient；2 effluent qualities are good；3, equipment is hardly damaged；4, it is convenient for Cleaning and maintenance；5, equipment cost is low, easy to maintain；6, without setting intermediate pool and promoting water pump after sbr reactor device technique；7, it can drop The buried depth of low subsequent technique or equipment saves construction investment.
