And for example an application number is that the Chinese invention patent application " a kind of waste disposal plant " of CN201210300793.X (publication number is CN103570186A) has disclosed so a kind of waste disposal plant, between each pond, be communicated with in order, bottom at equalizing tank, reaction tank, flocculation basin, coacervation pond, Aerobic Pond, anaerobic pond, mechanical forced formula solid-liquid separation tank and settling tank is provided with mud collection bucket, and the bottom at each mud collection bucket is also provided with shore pipe, each shore pipe is connected and communicates with sludge thickener, and pump is installed on shore pipe.
Above-mentioned two kinds of devices adopt mechanical systems that the sewage in device and medicament are mixed and vibrates and disposes of sewage, and can make like this equipment complexity, and cost is high, and the while height of equipment is very high, not easy care.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of topology layout for above-mentioned prior art present situation rationally and the high efficiency sewage treatment facility of being convenient to maintenance of good sewage processing effect, this device can make sewage in course of conveying, allow medicament and the abundant hybrid reaction of sewage, whole device is highly low simultaneously, is convenient to maintenance.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of high efficiency sewage treatment facility of being convenient to maintenance, comprise the reaction tube being together in series by pipe connecting between multiple, the reaction tube of initiating terminal is provided with the water inlet pipe entering for sewage, the reaction tube of least significant end is provided with for the transfer lime of discharging through the pretreated sewage of reaction tube, the bottom of each reaction tube is provided with waste pipe, and waste pipe place is provided with by-pass valve control, it is characterized in that: described each reaction tube is arranged on a platform being supported by pillar stiffener, one side of platform is provided with the cat ladder of climbing up platform for people, one side of described water inlet pipe and pipe connecting is provided with the chemical feed pipe communicating with water inlet pipe and pipe connecting respectively, chemical feed pipe is provided with by-pass valve control, the below of described platform is provided with Horizontal-type filtering tank, be separated into multiple filtration chambers by spaced polylith screen plate from bottom to top in Horizontal-type filtering tank, the bottom of Horizontal-type filtering tank is provided with the blow-off pipe being communicated with the filtration chamber of lowermost end, blow-off pipe is provided with by-pass valve control, described transfer lime is communicated with the filtration chamber of lowermost end, the top of Horizontal-type filtering tank is provided with the rising pipe being communicated with filtration chamber topmost.
As a kind of structure formation of reaction tube, above-mentioned water inlet pipe is arranged on the top of the reaction tube of initiating terminal, water inlet pipe extends downward a side bottom of reaction tube always, bottom mouth of pipe water outlet place of water inlet pipe is bent into parallel with reaction tube bottom, is positioned on the water inlet pipe of reaction tube and is laid with its bottom mouth of pipe water outlet in unidirectional the first spout hole; The entrance end of each pipe connecting is communicated with the top of last reaction tube, bottom mouth of pipe water outlet place of each pipe connecting is bent into parallel with reaction tube bottom, the exit end of each pipe connecting inserts and extends downward always the bottom of reaction tube from the top of reaction tube, be positioned on the pipe connecting of reaction tube and be laid with its bottom mouth of pipe water outlet in unidirectional the second spout hole; Described transfer lime is arranged on the top of the reaction tube of least significant end.Medicament and sewage mixing water spray by multiple spout holes, can make like this medicament and sewage mixing water in reaction tube, produce the swirling flow of rotation, are convenient to medicament and sewage fully mixes, and medicament is fully reacted.
Above-mentioned water inlet pipe is arranged on the bottom of the reaction tube of initiating terminal, is provided with successively corrugated tube, turbulent tank and transition conduit between the bottom of the reaction tube of water inlet pipe and initiating terminal; The entrance end of each pipe connecting is communicated with the top of last reaction tube, between the exit end of each pipe connecting and the bottom of a rear reaction tube, is provided with corrugated tube, turbulent tank and transition conduit; Described transfer lime is arranged on the top of the reaction tube of least significant end.First sewage pass through corrugated tube, due to the unexpected change of water (flow) direction, medicament and sewage mixing water clash in corrugated tube like this, make to realize between medicament and sewage impingement mix for the first time, entering turbulent tank carries out turbulent flow and makes to realize between medicament and sewage turbulent mixing for the second time again, entering in reaction tube, medicament and sewage are fully mixed, lifting sewage treatment effect afterwards.
Above-mentioned reaction tube inside is provided with and is provided with at a certain distance polylith turbulence plate, and each turbulence plate height is identical and arrive reaction tube top, at regular intervals between the top of turbulence plate and the top of reaction tube.The effect being stressed, mixing water enters reaction tube, first impacts the turbulence plate of bottom, and medicament and sewage run into various resistances at reaction tube and can produce and seethe like this, finally make medicament mix fully with sewage generation, by same principle,
The bottom of the turbulence plate of the most close above-mentioned reaction tube exit end is provided with orifice under pressure.Orifice under pressure is set is mixing water, to seethe effect better.
Above-mentioned turbulence plate has two, is respectively the first turbulence plate and the second turbulence plate.The number of turbulence plate can be carried out respective design according to varying in size of reaction tube.
The upstream face of above-mentioned each turbulence plate is the inclined-plane tilting to reaction tube water outlet direction gradually from top to bottom.Mixing water can produce impingement flow after impacting inclined-plane like this, makes medicament and sewage produce more strong seething at reaction tube, promotes that medicament mixes with sewage.
Evidence, the angle between the inclined-plane of above-mentioned turbulence plate and reaction tube bottom surface is taking 120～140 ° as good
Above-mentioned blow-off pipe is arranged on the Horizontal-type filtering tank with the relative one side of transfer lime.Water inlet by pipe connecting is washed away, and the water inlet of the sewage foreign body connected tube after reaction is flushed to that face of blow-off pipe, and sewage foreign body is convenient to discharge near blow-off pipe.
Above-mentioned rising pipe has two, is arranged in the both sides on Horizontal-type filtering tank top.Can increase like this aquifer yield in the unit time.
Compared with prior art, the invention has the advantages that:
1, filter tank body and medicament mixed equipment (reaction tube) separately, the processing power of sewage is strengthened greatly like this, while maintenance, only need to climb up steel platform safeguards simultaneously, solve existing sewage disposal and adopted integrated design, although volume has reduced, safeguard and manufacture all problems of aspect not.
2, adopting filtration unit is Horizontal-type filtering tank, and is all to adopt vertical hay tank at present, adopts the height of vertical design apparatus to increase, and in the time safeguarding, staff exists larger potential safety hazard.
3, the present invention adopts the design of rational shape and structure, makes between medicament and sewage hybrid reaction fully, does not need to lodge external force, and as stirring, the methods such as heating make medicament fully react with sewage, have saved production cost.
