Abstract
The utility model relates to a wastewater treatment system, sequentially comprising a hydrolysis regulating pool, a UASB (upflow anaerobic sludge blanket) pool, an oxidation ditch, a secondary sedimentation pool, a dephosphorization sterilization treatment pool and a clean water pool. The wastewater is treated systematically. The wastewater treatment system has a simple process, a reasonable and effective configuration and high treatment efficiency, for example, the effluent quality index can reach the level that the COD (chemical oxygen demand) is smaller than or equal to 100 mg/L for the wastewater with the COD smaller than or equal to 3000 mg/L.
Description
Technical field
The utility model relates to field of waste water treatment, particularly a kind of Waste Water Treatment.
Background technology
Both at home and abroad generally adopt targetedly biochemical method to handle waste water according to the different water quality of waste water, handle directly, effect is remarkable, and has advantages such as the simple and floor space of operation is little.
The utility model content
The utility model provides a kind of simple and effective Waste Water Treatment in order to overcome the deficiency of above technology.
The utility model is achieved through the following technical solutions:
A kind of Waste Water Treatment, order arranges hydrolyzing regulation pond, UASB pond, oxidation ditch, second pond, dephosphorization germicidal treatment pond and the clean water basin of band grid, and systematize is handled.
Preferably, described UASB pond comprises into water and water distribution system, reactor cell body and triphase separator; Described oxidation ditch is made up of ditch body, aerator, Inlet and outlet water device, water conservancy diversion and mixing equipment.
The beneficial effects of the utility model are: Waste Water Treatment flow process of the present utility model is simple, rationally effectively, the processing efficiency height is the waste water of COD≤3000mg/L for index for example in configuration, and the effluent quality index can reach COD≤100mg/L.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technique means of the present utility model, and can be implemented according to the content of specification sheets, below preferred embodiment of the present utility model and conjunction with figs. describes in detail as after.Embodiment of the present utility model 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 of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is made specific description.
In conjunction with shown in Figure 1, a kind of Waste Water Treatment of the present utility model, waste water be successively through the subsequent treatment in hydrolyzing regulation pond, UASB pond, oxidation ditch, second pond and dephosphorization germicidal treatment pond of band grid, enters water outlet behind the clean water basin.Described UASB pond comprises into water and water distribution system, reactor cell body and triphase separator; Described oxidation ditch is made up 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 (mainly being methane and carbonic acid gas) 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 the mud granule, and the gas that adheres to and do not adhere to rises to reactor head.Rise to the bottom of the mud bump phase reactor gaseous emission device on surface, cause the mud flco degassing of adhering to bubble.Bubble discharges the surface that the back mud granule will be deposited to 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.Place acting as the gaseous emission device and preventing that the biogas bubble from entering the settling region of the baffle plate that extremely makes under the 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 slit.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 the triphase separator will remain on frictional force on the skew wall above 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 circulates continuously, and oxidation ditch uses under the extended aeration condition usually.Oxidation ditch uses a kind of aeration and agitator with direction control, 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, also can be 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 utility model and enforcement according to this for technical conceive of the present utility model and characteristics being described, its objective is, can not limit protection domain of the present utility model with this.Variation or the modification of every equivalence of having done according to the essence of the utility model content all should be encompassed in the protection domain of the present utility model.
