Abstract
The invention relates to a wastewater treatment technology. According to the wastewater treatment technology, wastewater are sequentially treated through a hydrolysis adjusting tank, a UASB (Upflow Anaerobic Sludge Blanket) tank, an oxidation ditch, a secondary sedimentation tank and a phosphorus removal and sterilization treatment tank, and then enters a clear water tank to be discharged. The wastewater treatment technology provided by invention is simple in technological processes and reasonable and effective in configuration and has high treatment efficiency; and for example, after the wastewater with the COD (Chemical Oxygen Demand) being less than or equal to 300mg/L is treated according to the technology, the COD of the effluent quality is less than or equal to 100mg/L.
Description
Technical field
The present invention relates to field of waste water treatment, particularly a kind of waste water treatment process.
Background technology
Both at home and abroad the general water quality different according to waste water adopts targetedly biochemical method to process waste water, processes directly, and effect is remarkable, and has the advantages such as the simple and floor space of operation is little.
Summary of the invention
The present invention provides a kind of simple and effective waste water treatment process in order to overcome the deficiency of above technology.
The present invention is achieved through the following technical solutions:
A kind of waste water treatment process, waste water pass through the subsequent treatment in hydrolyzing regulation pond, UASB pond, oxidation ditch, second pond and dephosphorization germicidal treatment pond successively, enter water outlet after clean water basin.
Preferably, described UASB pond comprises into water and water distribution system, reactor cell body and triphase separator; Described oxidation ditch is comprised of ditch body, aerator, Inlet and outlet water device, water conservancy diversion and mixing equipment.
The invention has the beneficial effects as follows: sewage treatment technology process of the present invention is simple, rationally effectively, processing efficiency is high, is for example the waste water of COD≤3000mg/L for index in configuration, and the effluent quality index can reach COD≤100mg/L.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, for can clearer understanding technique means of the present invention, and can be implemented according to the content of specification sheets, below preferred embodiment of the present invention and coordinate accompanying drawing to be described in detail as follows.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is the schematic flow sheet of waste water treatment process of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is made specific description.
In conjunction with shown in Figure 1, a kind of waste water treatment process of the present invention, waste water be successively through the subsequent treatment with the hydrolyzing regulation pond of grid, UASB pond, oxidation ditch, second pond and dephosphorization germicidal treatment pond, enters water outlet after clean water basin.Described UASB pond comprises into water and water distribution system, reactor cell body and triphase separator; Described oxidation ditch is comprised of ditch body, aerator, Inlet and outlet water device, water conservancy diversion and mixing equipment;
Preferably, be the waste water of COD≤3000mg/L for index, the effluent quality index can reach COD≤100mg/L.
UASB pond reaction principle: waste water is introduced the bottom of reactor as far as possible uniformly, and sewage is upwards by comprising the Sludge Bed of granule sludge or floc sludge.Anaerobic reaction occurs in the process that waste water contacts with mud granule.The biogas that produces under anaerobic state (being mainly methane and carbon dioxide) has caused inner circulation, and this is for the formation of granule sludge and keep favourable.Some gases that form at sludge blanket are attached on mud granule, and the gas that adheres to and do not adhere to rises to reactor head.Rise to the bottom of the mud shock phase reactor gas launcher on surface, cause that the mud flco of bubbles attached is degassed.After bubble discharges, mud granule will be deposited to the surface of Sludge Bed, and the gas that adheres to and do not adhere to is collected into the collection chamber of the triphase separator of reactor head.Be placed in acting as gas launcher and preventing that the biogas bubble from entering the settling region of the baffle plate that extremely makes under unit interstices, otherwise will cause that the wadding of settling region is moving, can hinder solids precipitation.The liquid that comprises some remaining solids and mud granule enters the settling region through the separator gap.Because the open area of the skew wall settling region of separator increases near the water surface time, so upflow velocity is reducing near discharge point.Because reducing the mud flco, flow velocity can flocculate and precipitate in the settling region.The mud flco that is accumulated on triphase separator will remain on frictional force on skew wall over it to a certain extent, and it will slide back to reaction zone, and this part mud will react with entering organic matter of water again.
The continuous ring type reaction tank of oxidation ditch utilization is made biological reaction tank, and mixed solution closed aeration channel in this reaction tank carries out continuous circulation, and oxidation ditch uses under the extended aeration condition usually.Oxidation ditch uses a kind of aeration and agitator of controlling with direction, the material transfer horizontal velocity in the reaction tank, thus the liquid that is stirred is circulated in the closed type channel.The planeform of oxidation ditch ditch body is generally selected annular, can be also rectangle, L shaped, circular or other shapes, and the ditch end surface shape mostly is rectangle and trapezoidal.
Above-described embodiment just is to allow the one of ordinary skilled in the art can understand content of the present invention and implement according to this for technical conceive of the present invention and characteristics being described, its objective is, can not limit protection scope of the present invention with this.Variation or the modification of every equivalence that the essence of content has been done according to the present invention all should be encompassed in protection scope of the present invention.
