Abstract
The invention discloses a wastewater pretreatment flow distribution and separation technology for removing particle solid pollutants. The wastewater pretreatment flow distribution and separation technology comprises the following steps that firstly, wastewater is collected by a drainage pipeline and automatically flows into a smooth flow residue removing, sand settling and mud falling mechanism; secondly, the pretreated wastewater enters a pH value regulating tank, and the pH is regulated to be 6-9; thirdly, then the wastewater automatically flows into a coagulating tank, wherein the effective dosage of a coagulating agent is 20-50 mg/L; fourthly, a wastewater flow guiding groove suction filtration mechanism is used for flow distribution pretreatment; fifthly, then the wastewater is sequentially fed into a facultative hydrolysis tank, a primary aerobic contact oxidation tank, a delayed biochemical tank and a secondary aerobic contact oxidation tank by a water pump for secondary biochemical treatment, and tail water meeting the standard after precipitation and reverse multi-filtration treatment is recycled or automatically flows to a wastewater drainage pipe network. By means of the technological process, after the pretreatment flow distribution technology, the COD of the wastewater can be reduced by 50-60% or above, the subsequent treatment load is greatly relieved, and it can be ensured that the SS of outlet water stably meets the standard.

(2) sewage after pretreatment enters acid-alkali accommodation pond, makes the water quality of sewage, the water yield be regulated, and pH is adjusted to 6～9；
(3) then sewage self-flowing enters coagulating basin, and effective dosage of coagulant is 20～50mg/L, and sewage carries out semi-static flocculation 5～10 minutes in described coagulating basin；
(4) again through sewage diversion trench suction filter mechanism Individual pretreatment, substantial amounts of larger particles solid-state and macromolecular mass pollutant, foreign material in sewage are removed further；
(5) then sewage is sequentially sent to facultative hydrolytic tank, one-level aerobic contact oxidation pond, time delay biochemistry pool, two grades of aerobic contact oxidation ponds carry out secondary biochemical treatment, uninterrupted hydrolysis Zhong Chen district it is provided with, vacuum in draft tube after precipitation and reverse polynary filtration treatment are up to standard or certainly flow to blow-off pipe net between described one-level aerobic contact oxidation pond and described two grades of aerobic contact oxidation ponds.
Use technique scheme, the method have the advantages that
Owing to being provided with above-mentioned technological process, after this pretreatment shunting process, the COD (COD) of sewage can be made to reduce 50～more than 60%, significantly reduce the load of subsequent treatment, it is ensured that the SS stably reaching standard of water outlet.Those skilled in the art is it will be understood that the difference that above-mentioned sewage diversion trench suction filter mechanism may utilize the different physical characteristic of material, bulk density and heavy and light phase carries out physical separation.
In addition, by above-mentioned steps, sewage is to remove slag the equipment such as sand setting Jiang Ni mechanism and coagulating basin from flowing into advection successively, water after process is also from flowing to blow-off pipe net, that is, the flowing of water utilizes water-head to flow automatically, it is not necessary to arrange suction pump in each position, the most energy-conservation.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described further.
Remove sewage disinfection treatment shunting and the separating technology of the solid contaminant of larger particles, comprise the following steps: first (1) sewage collected gravity flow by drainage pipeline and enter advection and remove slag sand setting Jiang Ni mechanism, remove most floating, the suspending sundries carried secretly in sewage and silt particle etc., make nondegradable SS concentration in sewage reduce；(2) sewage after pretreatment enters acid-alkali accommodation pond, makes the water quality of sewage, the water yield be regulated, and pH is adjusted to 6～9, it is ensured that sewage disposal system unimpeded；(3) then sewage self-flowing enters coagulating basin, and effective dosage of coagulant is 20～50mg/L；(4) flocculation (semi-static 5～10 minutes) through coagulating basin generates the sewage of big alumen ustum, again through sewage diversion trench suction filter mechanism Individual pretreatment, remove substantial amounts of larger particles solid-state and macromolecular mass pollutant, foreign material, mud and sand in sewage further.After this pretreatment shunting process, the COD (COD) of sewage can be made to reduce 50～more than 60%, significantly reduce the load of subsequent treatment.(5) then sewage is sequentially sent to facultative hydrolytic tank by water pump, one-level aerobic contact oxidation pond, time delay biochemistry pool, two grades of aerobic contact oxidation ponds carry out secondary biochemical treatment, vacuum in draft tube after precipitation and reverse polynary filtration treatment are up to standard or certainly flow to blow-off pipe net.Sewage enters facultative hydrolytic tank and carries out acidification hydrolization, under the effect of aerobic-anaerobic microbe, larger molecular organics matter is hydrolyzed into small-molecule substance to reach to adsorb, to retain, degradation of contaminant and the purpose of biodegradability increased water quality.It is the microbial strains the utilizing different population difference feature to sewage treatment function under different dissolved oxygen conditions that aerobic contact oxidation (improvement A/O method) pond arranges main purpose, carrys out intensive treatment process, makes treatment effect reliable and stable.It is provided with uninterrupted hydrolysis Zhong Chen district, it is therefore intended that biological sludge produced by precipitation nitrification two inter-stage biochemical treatment at two inter-stages.In the contact-oxidation pool aeration zone of leading portion, use the high aeration zone feature of aeration aerating mode, the microorganisms such as the antibacterial perched on biochemical filler are under high aerobic condition, the absorption and the cohesion that utilize the microorganism of bacterium race in based on the biochemical process of an elementary reaction are removed the most organic in sewage and carry out biodegradation, and this process dwell time is shorter；Then, in back segment bio-contact oxidation strengthening stable process, utilize dissolved organic matter in sewage to carry out multi-element biologic degraded, be allowed to be decomposed into carbon dioxide and water, make terminal sewage qualified discharge.The setting of time delay biochemistry pool is intended to change the dissolved oxygen concentration of secondary biochemical treatment unit, it is allowed to produce the alternation procedure of hyperoxia hypoxia hyperoxia, ensure the reaction power of biochemical system, overcome microorganism under simple aerobic or anaerobic condition, the biochemical power of reduction, the comprehensive unit efficiency improving processing unit is blocked due to the accumulation of nucleic acid.By the alternation procedure of hyperoxia hypoxia hyperoxia, the nitrification and denitrification significant reaction of microorganism, the ammonia nitrogen in sewage and biological phosphorus is made to be able to denitrogenation and removal, it is ensured that ammonia nitrogen concentration reaches discharge standard.
Those skilled in the art is it will be understood that the difference that above-mentioned sewage diversion trench suction filter mechanism may utilize the different physical characteristic of material, bulk density and heavy and light phase carries out physical separation.
Additionally, by above-mentioned steps, sewage is to remove slag the equipment such as sand setting Jiang Ni mechanism and coagulating basin from inflow advection successively, water after process is also from flowing to blow-off pipe net, say, that the flowing of water utilizes water-head to flow automatically, without arranging suction pump in each position, the most energy-conservation.
Above in conjunction with specific embodiment, the present invention is described in detail; but embodiments of the present invention are not limited in above-mentioned embodiment; the present invention can be made various deformation according to prior art by those skilled in the art, and these broadly fall into protection scope of the present invention.
