Description
Technical field
The present invention relates to sewage treatment area, more particularly to a kind of horizontal effluent treatment plant that can be embedded in underground.
Background technology
At present under the situation of available water resource increasingly depleted, recycling ever more important is carried out to sewage.Root
Show according to related data, in the ratio of wastewater treatment in China level, city accounts for 78%, organic town and accounts for 15%, village and accounts for 6%.Examine
Consider the area just outside a city gate town that organic town is greatly county town, sewage disposal level only account for not if real organic town is counted
To 10%.Small towns sewage collecting design of pipe networks imperfection, builds delayed, and most of township and rural area are all confluence of rainwater and sewage, along ditch
Canal is discharged, and waste water collection rate is low.Small towns sewage is typically managed by the establishment of town government, is provided with sewage management person, is in charge of day to day work,
But as website distribution relatively dissipates, amateur manager lacks fortune pipe experience, manages lack of standardization, the long-acting supervisor that government is formulated
System is unable to effective execution.Due to lack operational management professional, cause effluent quality to be difficult up to standard, facility maintenance level compared with
Low, maintenance maintenance easily causes the too fast damage of equipment, premature failure not in time, causes early stage construction input and expected effect to be put to east
Stream.In addition, villages and small towns sewage disposal website is more, distribution dissipates, small scale, and lacks the management of specialty, cause water quality not up to standard, and
Government is but difficult to accountability to people, let alone administrative penalty, and sewage treatment works implement not in place, causes sewage disposal scheme difficult
To prove effective, many sewage websites " existing in name only ".In a word, as villages and small towns website is more, management personnel mostly villager is part-time, or villages and small towns
Locality voluntarily manages, and professional degree is not high, lacks a sense of responsibility, and lack of wisdomization management, considerably increases supervision difficulty, causes
" getting half the result with twice the effort ", wastes substantial amounts of manpower, material resources and financial resources.This has resulted in small towns waste water control, and there are the following problems：(1) place
Reason rate is low；(2) waste water collection rate is low；(3) installation fishery maintenance management is difficult；(4) government regulation is difficult；(5) lack professional thing
Industry operation management and intelligent supervision platform.
Typically all efficiency is higher in a certain respect for existing sewage disposal device, is but difficult to meet the demand of other side,
Various functions can not be accomplished to be integrated in one to sewage process, and need the cooperation of plurality of devices to process sewage, from
And investment is high, floor space is big, the low many restrictions of production efficiency complete equipment is provided with, it is difficult to improve sewage disposal effect
Rate.On the other hand, mudpan is typically equipped with existing sewage disposal device, and the mudpan when in use
As do not carry out or be difficult to cleaning, easily cause sludge accumulation, so as to cause mudpan to block, follow-up work is difficult
To proceed.Sum it up, as a variety of drawbacks of existing sewage disposal device make it unsuitable for applying to small towns life dirt
The process of water.
More or less presence in sanitary sewage has general sedimentation tank to process heavy metal and the microorganism do not fallen, and this is accomplished by
By biochemical treatment system, biochemical treatment system is mainly made up of the processing system such as anaerobism, anoxia, aerobic, in sewage load
In the case of larger, generally it is made up of anaerobic pond, anoxic pond, Aerobic Pond, in biochemical treatment tank, needs to add anaerobe, good
Oxygen bacterium etc., the nitrogen, P elements in making them with sewage react, and remove rich nutritive material；In order that sewage uniform throughout is anti-
Should, it is required to impeller is configured in pond, in making pond, sewage keeps flowing；However, due in cesspool chemical substance more live
Sprinkle, and impurity is more, the environment residing for impeller is very severe, therefore, the phenomenon such as impeller corrosion and scaling or leak electricity short-circuit
Unavoidably, therefore, not only configure the relatively costly of impeller, and be easily damaged, not easy care.
The Chinese patent literature of Publication No. CN202657980U discloses a kind of sewage-treatment plant, and which is included at sewage
Reason case, sewage storage box, gas combustion apparatus, heating calancria and exhaust fan, sewage storage box pass through transfer pipeline and sewage
Treatment box connection connection, waste water treatment box upper end are provided with fumer, and its inside bottom is provided with heating calancria, one end of heating calancria
Stretch out and be connected with gas combustion apparatus outside waste water treatment box, its other end is connected with fumer by vertical tube, also sets in fumer
There is the steam comb connected with waste water treatment box, fumer side is provided with total air escape pipe, and the pipeline of total air escape pipe is provided with heat extraction
Blower fan and air filter, the bottom of waste water treatment box are provided with band valve blow-off line, and blowdown screw rod is set in the blow-off line.Should
Device retains heavy metal dirt to be reclaimed by heavy metal containing sewage is carried out moisture evaporation, is capable of achieving to containing heavy metal-polluted
The fine process of water.But as the device is that overall heating is carried out to the sewage in waste water treatment box via heating calancria, therefore
Its moisture evaporation speed is slower, causes sewage treating efficiency relatively low, is difficult in actual use meet wanting for sewage disposal speed
Ask.
