Abstract
The invention discloses an absorption/precipitation/hydrolyzation synchronization sewage treatment process. According to the process, a sewage treatment pond is involved, and one side of the upper part of the sewage treatment pond is provided with a water discharging tank; predicated sludge at the bottom of the sewage treatment pond is pumped out by a sludge pump, the predicated sludge and sewage to be treated are fed into the upper part of the sewage treatment pond by a sludge return pipe and are mixed in the sewage treatment pond for adsorption and precipitation, and hydrolyzation is performed in the precipitation process. The process of adsorbing organic matter in the sewage by sludge mainly containing microorganisms, the process of precipitating the sludge mainly containing microorganisms, and the process of hydrolyzing the organic matter in the sewage by the sludge mainly containing microorganisms are performed in the same pond simultaneously, and the residual sludge is discharged at fixed time. By the process, the engineering investment cost is greatly saved; and the process has the advantage of small occupied area, and can solve the problem of large occupied floor in the process of sewage treatment. The process is simple, improves the sewage treatment efficiency and is particularly suitable for treating nonbiodegradable organic sewage with low biodegradability, and is also suitable for treating organic sewage.
Description
Technical field
The present invention relates to the sewage treatment process of a kind of synchronous absorption/deposition/hydrolysis, be particularly useful for the pre-treatment of difficult-degradation organic sewage, also be applicable to the processing of other organic sewage or organic waste water.
Background technology
Along with the raising of Public Environmental Awareness is more and more stricter to the limitation standard of the discharging of WWT with both at home and abroad; Especially in the last few years discharged a large amount of relatively poor organic wastewater with difficult degradation thereby of biodegradability in the chemical process, researching and developing efficiently, the organic wastewater with difficult degradation thereby treatment technology is the focus in water pollution control engineering field always.
Summary of the invention
The objective of the invention is to overcome the weak point in the prior art, provide a kind of technology simple, improved the sewage treatment process of waste water treatment efficiency, floor space is little, construction investment is few synchronous absorption/deposition/hydrolysis.
The sewage treatment process of synchronous absorption of the present invention/deposition/hydrolysis comprises treatment tank, and treatment tank top one side is provided with sk-; Adopt sludge reflux pump that the precipitating sludge of treatment tank bottom is extracted out, together get into the top of treatment tank through mud return line and pending sewage, mixing is adsorbed, is precipitated and hydrolysis takes place in precipitation process in treatment tank.
Described precipitating sludge and pending discharge of sewage ratio are 2:1～60:1.
Beneficial effect: the present invention will be that main mud is that main sludge settling process and mikrobe is that main mud carries out the process that is hydrolyzed of organism in the sewage simultaneously to organic adsorption process, mikrobe in the sewage with the mikrobe, and the WWT of absorption/deposition/hydrolysis synchronously makes to be carried out absorption, deposition, three processes of hydrolysis in same pond.Have remarkable advantage such as shorten the treatment time, floor space is little, solved preferably the existing technology investment of difficult degradation saprobiont hydrolysis higher, take up an area of more problem.Its technology is simple, waste water treatment efficiency is high, floor space is little, construction investment is few, has practicality widely.
Description of drawings
Fig. 1 is a sewage treatment process synoptic diagram of the present invention.
Among the figure: 1-precipitating sludge, 2-sludge reflux pump, 3-sewage, 4-sk-.
Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are done further to describe:
Synchronous absorption/deposition of the present invention/hydrolysis sewage treatment process; Adopt sludge reflux pump 2 that the precipitating sludge 1 of treatment tank bottom is extracted out; Together get into the top of treatment tank through mud return line and pending sewage 3, in treatment tank, mix and adsorb, precipitate and hydrolysis takes place in precipitation process.To be that organism adsorption process in main 1 pair of sewage 3 of precipitating sludge, mikrobe are that main sludge settling process and mikrobe are be hydrolyzed process and in a pond, carrying out simultaneously of organism in main 1 pair of sewage 3 of precipitating sludge with the mikrobe; Absorption, deposition, three processes of hydrolysis are carried out in same pond; And the precipitating sludge from the bottom mixes the common top that gets into treatment tank with sewage; Hydrolysis and deposition are taken place by precipitating sludge absorption in organism in the sewage 3 simultaneously; Sewage 3 after the processing is discharged through sk-4 on the top of treatment tank, and the redundance of treatment tank bottom mud is discharged as excess sludge.Precipitating sludge and the two liquid flow rate ratio of sewage from the bottom, pond are 2:1-60:1; The big more effect of this ratio ratio in the 2:1-60:1 scope is good more; Consider energy-conservation factor, the best when ratio is 8:1-12:1 also can reduce the power of backflow when guaranteeing treatment effect.
But water inlet place, described treatment tank body top is provided with the up-down adjustment discharging device, during work:
(1) precipitating sludge from pond body bottom mixes the common body top, pond that gets into sewage;
(2) precipitating sludge and the sewage mixed solution mud from body top, pond adsorbs organism in the sewage;
(3) from the precipitating sludge of body top, pond adsorb organic compound in the action of gravity settle;
(4) mikrobe in the precipitating sludge of the adsorb organic compound of action of gravity settle is hydrolyzed to the precipitating sludge adsorbed organic matter and regularly discharges excess sludge.
Claims (2)
1. the sewage treatment process of a kind of synchronous absorption of the present invention/deposition/hydrolysis comprises treatment tank, and treatment tank top one side is provided with sk-; It is characterized in that: adopt sludge reflux pump (2) that the precipitating sludge (1) of treatment tank bottom is extracted out; Together get into the top of treatment tank through mud return line and pending sewage (3), in treatment tank, mix and adsorb, precipitate and hydrolysis takes place in precipitation process.
2. the sewage treatment process of synchronous absorption according to claim 1/deposition/hydrolysis is characterized in that: described precipitating sludge and pending discharge of sewage ratio are 2:1～60:1.
