Description
Technical field
The utility model relates to Hydraulic and Hydro-Power Engineering water treatment and resource reclaims field, specifically a kind for the treatment of system of sandstone aggregate utilization of wastewater resource.
Background technology
Concerning Construction for Hydroelectric Project, the required sandstone aggregate of scale operation concrete needs to add water and rinses in the course of processing, makes its silt content, wraps up in powder degree and meet concrete production requirement, thereby produce a large amount of high-turbidity waters.Monitoring materials shows, in sandstone aggregate processing waste water, concentration of suspension is 30,000～120,000mg/L, considerably beyond mining, the highest permission emission concentration standard one-level of the Mineral Processing Enterprises waste water suspension waters of stipulating in < < integrated wastewater discharge standard > > GB8978-1996, be 70mg/L, secondary waters is 300mg/L and sandstone aggregate processing water supply standard concentration of suspension≤100mg/L (SL303-2004).
Enter the later stage nineties in last century, the environmental requirement of China's construction of hydropower stations improves constantly, and sandstone aggregate system of processing starts general supporting design waste water treatment plant, and conventional treatment process is natural sedimentation method and coagulant sedimentation.Sandstone aggregate processing waste water treatment capacity is large, concentration of suspension is high, the extensive settling tank diameter of auxiliary construction >30m usually, and larger floor space causes settling tank in the addressing in high mountain gorge area and builds extremely difficult.For improving precipitate and separate effect, a large amount of flocculation agents, as PAC and PAM etc. enters settling tank by water distribution dosing, when improving suspended substance processing efficiency, produce a large amount of body refuses, and often because deslagging does not freely interrupt the operation of settling tank.In addition, flocculation agent is used has greatly increased processing cost.
About sandstone aggregate processing waste water, process, the secondary advection sedimentation that the Chinese patent that publication number is CN102430272A discloses a kind of sandstone processing waste water slows down the method that sandstone blowdown system stops up.Publication number is the treatment process that the Chinese patent of CN102153213B discloses the sandstone aggregate processing waste water of the centrifugal desliming of a kind of secondary Horizontal helical type centrifuge, dosing flocculation two-stage precipitation.Publication number is the shield structure sludge-water separating system that the Chinese patent of CN202538513U discloses a kind of screening+rotating separation+press filtration of vibrating, this technique is first sieved out the rubble that particle diameter is greater than 5mm, then rotating separation sand and particulate mud, last press filtration particulate mud, mud cake outward transport, this system is mainly for shield slurry separate design, the shortcoming that existence can not the required material of disposable multi-stage screening.For sandstone aggregate processing waste water, process, prior art still has the following disadvantages:
1, adopt stirring and segregation, helical feed or spiral separator etc. to carry out the simple solid-liquid separation of machinery, equipment cost and process cost are higher;
2, the solid content such as the influent waste water suspended substance after solid-liquid separation, stone flour colloid is higher, needs even three grades of precipitations of secondary, and settling tank floor space is large, and precipitation and deslagging mud amount are large;
3, precipitation process height relies on chemical agent, has increased processing cost, has improved precipitation and bed drain purge;
4, the mud cake slag after sandstone aggregate processing waste water solid-liquid separation is processed in waste mode, the sand and stone resources difficulty of reuse different-grain diameter composition;
As can be seen from above; sandstone aggregate processing waste water not yet has a set of economy, reliable and effective treatment process at present; the utmost point is necessary to take compact construction, solid-liquid separation efficiency is high, running cost is cheap sandstone aggregate processing waste water treatment system; reduce deposition facility scale; the flocculation agent of breaking away from wastewater sedimentation process relies on, and reclaims the sand and stone resources in waste water, purifying waste water after Treatment for Reuse; reduce disposal of pollutants, preserve the ecological environment.
