Description
Technical field
The present invention relates to a kind of sewage disposal device and method thereof, be specifically related to a kind of concrete plant area sewage water treatment method.
Background technology
At present, at home under the policy guide of " energy-saving and emission-reduction ", in addition to personal lifestyle consumes, especially during concrete production, all there is the place of a lot " energy-saving and emission-reduction ".For example, it is possible to will recycle after the sewage disposal in concrete production plant area, such it is advantageous in that the utilization rate that improve mud, and has saved water resource, also improve the utilization rate of water resource simultaneously, reduce production cost.Simultaneously in industrialized production plant area, partial discharge water can be with recycling, as circulating condensing, the product of some equipment or the course of processing carried out cooling process.
Substantial amounts of discharge water can be produced during concrete production, but due to different to the Land use systems of water in different product processing, in discharge water, some is rich in a large amount of composite partss, it is impossible to is directly discharged in river, otherwise can cause the pollution to environment.And for the mud in concrete plant area, can recycle after processing, reach the effect of resource reclaim.
Such as, the patent " automated vehicle rinse-system " that the applicant declared in 2014 then describes the equipment that the dump truck to transport concrete is rinsed, and the sewage after being rinsed exists a small amount of oil, after needing it is processed, can reuse.
Therefore this be accomplished by one can be for concrete plant area use, sewage disposal and mud recovery method that cost of manufacture is low solve.
Summary of the invention
The present invention is directed to that existing concrete plant area exists sewage cannot process in time, sewage and mud can not the defects of recycling timely, there is provided a kind of concrete plant area sewage water treatment method to solve the problems referred to above, thus reach to clean plant area, the effect of resource reclaim recycling.
The solution of the present invention is achieved in that a kind of concrete plant area sewage water treatment method, comprises the following steps:
1) sewage with mud is collected from road surface or trucd mixer cleaning area, and the static oil removal carrying out 180min-720min separates, and use oil taking apparatus absorption to be removed at the oil of water surface；
2) oil content of sewage is reduced to less than 3%, subsequently sewage is carried out filter pressing and forms mud, sludge moisture content is made to be reduced to 5%-10%, clear water is collected, and mud is stirred, mixing speed is 50r/min-80r/min, and mixing time is 5-20min, and injects the clear water of sludge quality 0.1-0.15 times；
3) mud after stirring is transported in seperator cesspool by strong sewage pipeline, by the clear water in clear water reserviors, strong sewage pipeline is carried out subsequently；
4) subsequently the mud in seperator cesspool is collected.
The general plotting of the present invention is: can carry out the feature reused according to mud after filtering out oil body, arrange multiple filtering ponds, sewage carries out oil removing and separates mud recycling.
In the present invention, as further scheme, described mud is equipped with supersonic generator at seperator cesspool sidepiece and bottom, and when mud needs to extract from seperator cesspool, the supersonic generator of sidepiece and bottom starts.Found by research, sewage, be collected, by the vibrations of ultrasound wave, so that its molecular structure becomes finer and smoother, thus more can meet the production requirement of concrete plant area when recycling.
In the present invention, as the technical characteristic of such scheme, when supersonic generator starts, first starting sidepiece supersonic generator, tranmitting frequency is 5KHZ-6KHZ, and power density is 0.1w/cm2-0.2w/cm2, the opening time is 4 minutes, after sidepiece supersonic generator starts 2 minutes, restarts supersonic generator bottom seperator cesspool, and tranmitting frequency is 30KHZ-52KHZ, and power density is 2.3w/cm2-4.6w/cm2, the opening time is 2.5 minutes.
In the present invention, as another kind of technical scheme, when described supersonic generator starts, starting supersonic generator, side-emission frequency is 3KHZ-5KHZ, and power density is 0.05w/cm simultaneously2-0.2w/cm2；Bottom supersonic generator, tranmitting frequency is 30KHZ-52KHZ, and power density is 2.3w/cm2-4.6w/cm2；Being turned off after sidepiece supersonic generator is opened 1 minute, bottom supersonic generator cuts out after continuing to run with 1 minute, is then turned on sidepiece supersonic generator and closes after 1.5 minutes.
In the present invention, as further scheme, after the mud in seperator cesspool is collected, seperator cesspool is rinsed by the clear water opened in clear water reserviors.
The invention has the beneficial effects as follows:
1. in the present invention, the element existed due to mud is more, therefore, novelty in seperator cesspool, mud is being carried out ultrasonic Treatment, so design, both decreased mud stickiness, its viscosity is made to be reduced to below 10cp, avoiding bottom and the sidepiece being bonded at seperator cesspool when mud is collected, simultaneously by vibration so that mud hybrid particles diameter is reduced to below 0.16mm, beneficially mud directly reclaims mixing as carried out in concrete production material producing recycling.
2., when ultrasound wave applies to Treatment of Sludge, mechanical effect can be produced.The mechanism of ultrasound wave can facilitate the emulsifying of mud, the liquefaction of gel and the dispersion of solid, when ultrasonic fluid medium is formed standing wave, the molecule floated on a liquid condenses upon because of the effect by mechanical force at node, formed periodically to oneself in space, so that mud is the finest and the smoothest, it is more convenient for reclaiming.
3. can be by the sewage in concrete production plant area be reclaimed, mud is separated with clear water, realize clear water to reclaim, carry out plant area and produce recycling, during mud can apply to concrete production again, so that whole production plant area realizes garden and produces, effectively reduce dust, having saved resource, the sophistication of the concrete after simultaneously reclaiming is high, is easily reused.
4. the present invention can effectively realize automated production, only need to enter in equipment by sewage, can realize mud and clear water automatism isolation, and the effect of classification, effectively reduces cost of labor automatically.
5. the present invention can implement interface differential technique with the automated vehicle rinse-system designed before, thus improves the utilization rate of sewage and mud.
6. the present invention designs succinctly, it is simple to the same industry promotes the use.
