Description
Technical field:
The present invention relates to a kind of starch wastewater treatment device and processing method thereof.
Background technology:
Rhizoma Solani tuber osi produces in starch process will produce substantial amounts of waste water, these starch wastewater content of organics are high, if without processing directly discharge, Organic substance contained in its water, the dissolved oxygen in water is consumed rapidly after entering water body, causing water hypoxia to affect the existence of Fish and other aquatic animals, in waste water, float easily under anaerobic decomposes generation foul smell simultaneously, worsens water quality.Owing to China's starch producing technology is relatively backward, the utilization rate of resource is relatively low, in starch production process substantial amounts of vegetable protein do not add utilization and with produce discharge of wastewater, not only have impact on environmental health, and cause huge waste.In starch wastewater treatment process, if it is possible to reclaim vegetable protein, accomplish the recycling of waste water simultaneously, will have broad application prospects.
Summary of the invention:
It is an object of the invention to provide a kind of starch wastewater treatment device and processing method thereof.
Above-mentioned purpose is realized by following technical scheme:
A kind of starch wastewater treatment device, its composition includes: grid pond, described grid pond is connected with regulating reservoir, described regulating reservoir is connected with flotation tank, described flotation tank is connected with anaerobic reactor, described anaerobic reactor is connected with preaeration sedimentation tank, and described preaeration sedimentation tank is connected with SBR.
Described starch wastewater treatment device, described regulating reservoir, described anaerobic reactor, described preaeration sedimentation tank, described SBR are connected with sludge concentration tank, and described sludge concentration tank is connected with between sludge dewatering.
Described starch wastewater treatment device, is connected with regulating reservoir between described sludge concentration tank, described sludge dewatering.
A kind of processing method of described starch wastewater treatment device, described method step is as follows:
nullProduce waste water to retain after bulk drift through mechanical grille，Enter regulating reservoir even regulation water quality and the water yield，Regulating reservoir sets mechanical stirring device，Former water mixing homogenizing is made by mechanical agitation，Stop float precipitation，Float flows into flotation tank with water，Add flocculant poly aluminum chloride (PAC) and polyacrylamide (PAM) simultaneously，Flotation tank water outlet flows into anaerobic reactor，Owing to starch wastewater is in acidity，Follow-up anaerobic treatment process can be made to be suppressed，Under the effect of acid-producing bacteria and methanogen，Most Organic substance is decomposed into inorganic molecules material and methane，Excess sludge enters sludge concentration tank，Methane can as the energy for producing after being processed by three-way separator collection and purification、Life uses，Water outlet then flows into preaeration sedimentation tank，Remove float and the harmful gas of anaerobic effluent，Increase the dissolved oxygen in water，Certainly flowing into SBR carries out Aerobic biological process in the water outlet of pre-exposure sedimentation tank，With the Organic substance in further degradation water.The mud that the processing units such as adjustment sedimentation tank, anaerobic reactor, pre-exposure sedimentation tank, SBR produce enters sludge concentration tank and concentrates, and improves the solid content of mud, makes moisture percentage in sewage sludge lower than 95%.Entering after mud is concentrated between sludge dewatering and carry out mechanical dehydration, the mud cake outward transport of generation, sludge concentration tank supernatant and mechanism filter-pressing liquid are back to adjustment sedimentation tank and are further continued for processing.
Beneficial effects of the present invention:
Regulating reservoir of the present invention adopts the homogenizing regulating reservoir of rectangle diagonal water outlet, the feature of this regulating reservoir is that effluent trough is diagonally arranged, waste water is by behind entrance pond, the left and right sides, just flow to effluent trough through the different time, the composite waste making effluent trough flows in different time, has thus reached to be automatically adjusted the purpose of all sums.
Due to the fact that the solid suspension content of waste water is significantly high, and containing substantial amounts of albumen, so setting a flotation tank, separation and Extraction protein, increase economic efficiency, alleviate the pressure of subsequent treatment structures simultaneously.
Anaerobic reactor of the present invention adopts semi-underground type reinforced concrete structure, and in order to meet in pond anaerobic state and prevent foul smell from dissipate, top, anaerobic reactor pond employing cover plate for sealing, outlet pipe and escape pipe set water seal arrangement respectively.
Preaeration sedimentation tank of the present invention adopts rectangular sedimentation tank, reinforced concrete structure, for removing float and the harmful gas of anaerobic effluent, increases the dissolved oxygen in water, creates favourable condition for Aerobic Process for Treatment.
Accompanying drawing illustrates:
Accompanying drawing 1 is the process chart of the present invention.
