Wherein confounding, mixed zone and the three district in flocculation district are parallelly connected the distributions in advance, again with the distribution of establishing ties in proper order of buffers, settling zone, the three district in clear water district. Each part is constituteed in a whole in this device, realizes high -efficient mixture, flocculation, mud -water separation, clear water and stores.
Description
Technical field
This utility model relates to high-salt wastewater process field.
Background technology
High-salt wastewater refers generally to the waste water of total saliferous mass fraction at least 1%, and essentially from the collection processing etc. of chemical plant and oil and natural gas, this waste water contains many kinds of substance (including salt, oil, organic heavy metal and radioactive substance).The way of production of brine waste is extensive, and the water yield increases the most year by year, and the impact that environment is caused by the organic pollution in removal saline sewage is most important.Using bioanalysis to process, the salts substances of high concentration is inhibited to microorganism, uses physico-chemical process to process, and investment is big, and operating cost is high, and is difficult to reach intended clean-up effect.
The Organic substance of high-salt-content organic wastewater is different according to production process, and contained organic kind and chemical property differ greatly, but contained salts substances mostly is the salts substances such as Cl-, SO42-, Na+, Ca2+.Although these ions are all nutrients necessary to growth of microorganism, the growth course of microorganism plays promotion enzyme reaction, maintain membrane equilibrium and the important function of regulation osmotic pressure.If but these ion concentrations are too high, microorganism can be produced suppression and toxic action, mainly performance: salinity is high, osmotic pressure is high, microbial cell dehydration causes cellular plasm to separate；Salting out makes dehydrogenase activity reduce；The high effect toxic to antibacterial of chloride ion；Salinity is high, and the density of waste water increases, and activated sludge easily floats loss, thus has a strong impact on the clean-up effect of biological treatment system.
High slat-containing wastewater processes and may be used without distillation and process, and such as multiple-effect evaporation, multistage flash evaporation, calm the anger distillation, Membrane Materials, but is difficult to promote because investment is higher with operating cost.
Consider the factor of investment and operating cost, the process of high slat-containing wastewater preferably uses comprehensive processing technique, to play the combination advantage of different disposal technique, such as biochemical materialization group technology, biochemical, film processes group technology etc., in combined treatment process, subsequent cell and a whole set of investment of processing system, operating cost can be reduced by suitable pretreatment unit.This high-salt wastewater pretreatment unit i.e. designs as the pretreatment workshop section of high-salt wastewater.
Utility model content
The purpose of this utility model is: provide a set of adaptable, high-salt wastewater pretreatment unit of simple and reliable process, high treating effect.
The technical solution of the utility model is: a kind of high-salt wastewater pretreatment unit, including the pre-mix zone being sequentially connected with, mixed zone, flocculation zone, relief area, settling zone, clear water zone；Mixed zone and flocculation zone are equipped with blender, are provided with mud scraper, water leg and inclined plate packing in settling zone, and wherein mud scraper is arranged in the bottom of settling zone, and inclined plate packing is on the top of mud scraper, and water leg is positioned at the topmost of settling zone.
Wherein pre-mix zone, mixed zone and three districts of flocculation zone are distributions in parallel, then are sequentially connected in series distribution with relief area, settling zone, three, clear water zone district.
The described valve opening and closing being connected by pipeline or adjacent region distribution.
It is provided with return duct bottom settling zone and is connected to flocculation zone；High-salt wastewater passes through the treatment effect of sludge reflux enhanced flocculation medicament after entering processing means；
High-salt wastewater pretreatment unit each district unit construction is in an entirety, it is achieved high efficient mixed, flocculation, mud-water separation, clear water store.
By pre-mix zone (1), mixed zone (2), flocculation zone (3) realize high-salt wastewater realize with flocculant, returned sludge quickly mixing, efficient flocculating, lay the foundation for raising effluent quality.
The beneficial effects of the utility model: high-salt wastewater pretreatment unit is by reasonably design, in high-salt wastewater pretreatment unit, each parts form in an entirety, realize high efficient mixed, flocculation, mud-water separation, clear water storage, pretreated water is in addition to keeping relatively low indicator of suspended solids, partial salts, Organic substance can also be removed, reduce investment and the operating cost of subsequent processing units, and then reduce the overall investment of high-salt wastewater processing system and operating cost.

Detailed description of the invention
Seeing Fig. 1～4, a set of high-salt wastewater pretreatment unit of the present utility model includes pre-mix zone (1), mixed zone (2), flocculation zone (3), relief area (4), settling zone (5), clear water zone (6), mixing and blending machine (7), flocculation stirring machine (8), mud scraper (9), water leg (10), inclined plate packing (11).
During the work of this device, high-salt wastewater first with returned sludge, flocculant, flocculation aid enters pre-mix zone (1), realize preliminary mixing, the most blended district (2) carries out strengthening mixing, reach the highly effective reaction of medicament and mud, enter flocculation zone (3) afterwards, realize flco cohesion, strengthen granule degree of compaction, buffered district (4) enters settling zone (5) afterwards, effect by inclined plate packing (11), granule in water and flco are deposited at the bottom of pond, mud is aggregated into bucket by mud scraper (9) and is discharged to sludge-tank and carries out subsequent treatment, supernatant collects clear water zone (6) through water leg (10), carry out successive depths process afterwards.
