Description

A kind of low energy consumption high suspended matter waste water treatment process and processing unit
Technical field
The present invention relates to the processing unit of high concentration suspended matter waste water, in particular at a kind of low energy consumption high suspended matter waste water Science and engineering skill and processing unit.
Background technique
With the development in an all-round way of China's economic society, environmental protection policy constantly improve and construction project environment supervision Continue to increase, sandstone production, power generation, mining, a large amount of productions containing high concentration suspended matter that the engineerings such as cavern excavation generate are useless Water has become the focus of social concerns.
Suspended matter refers to water body fine grained of the partial size less than 62 μm, mainly by silt, clay, protozoan, algae, thin The composition such as bacterium, virus and macromolecule organic, as the defeated shifting of water body forms wadding body and settles.Water body recovery technology and water resource, Water environment is closely related with Ecology.It is a series of that the increase of concentration of suspension causes water body physics, chemistry and biological nature to present Variation, relatively conventional adverse effect includes the decline of water landscape aesthetic feeling, water process expense increases, fishery resources decline and aquatic State system is seriously degenerated." water environment quality standard " (GB3838-2002) does not limit concentration of suspension in China, But " integrated wastewater discharge standard " (GB8978-1996) primary standard provides, all kinds of stain disease concentration of suspension must not be higher than 100mg/L.In national economy activity, the generations such as all kinds of sandstone aggregate processing, processing of stone, exploitation of mineral resources, selected flushing are given up Aqueous suspension concentration is typically up to thousands of or even tens of thousands of milligrams per liter, protects water ecological environment, by high concentration suspended matter purify to Qualified discharge is particularly significant.
For high concentration suspended matter, common treatment process is natural sedimentation method and coagulant sedimentation.High concentration suspended matter Waste water generally arises from the remote mountain areas for carrying out all kinds of mining and ore dressing, the horizontal sedimentation tank or radical sedimentation basin of auxiliary construction It is both needed to the biggish flat open ground of area, addressing is extremely difficult.The natural sedimentation time is generally longer, effect is poor, to accelerate wadding Retrogradation is formed sediment, and a large amount of flocculants such as PAC and PAM etc. enter sedimentation basin by water distribution dosing, is improving the same of suspended matter treatment effeciency When, the higher body refuse of a large amount of moisture content is produced, later period body refuse treating capacity and processing cost are increased.
Electric flocculation is gone in water removal using the precipitate metal hydroxides that soluble metal anode generates in electrolytic process The water treatment technology of polluter.The technology can effectively remove water-borne glue body and suspended matter pollutant matter.Studies have shown that electricity wadding It is solidifying that the concentration of suspension of slaughtering wastewater and electroplating wastewater can be made to be down to 31mg/L and 57mg/ respectively from 2390mg/L and 2737mg/L L.With traditional natural precipitating compared with coagulating sedimentation, there is electric flocculation no medicament to put into secondary pollution, mud-water separation effect is good, Body refuse moisture content is low, occupied area is small, is easily achieved the advantages that automatic control.Electric flocculation technique is lower than in processing at present Ultrahigh in efficiency in terms of the suspended matter of 3000mg/L, but be applied at high concentration suspended matter of the suspended impurity concentration higher than 3000mg/L The report of reason is less.
Summary of the invention
Through inventor experimental studies have found that, after the concentration of suspended matter in waste water to be processed reach a certain height, highly concentrated It spends under suspended state, influence of the electric flocculation to suspended particle surface charge is gradually reduced, and individual electric flocculation is unable to reach conjunction The treatment effect of lattice.For this purpose, the present invention is to solve the problems, such as that high suspended matter waste water is difficult to be fully cleaned up processing by electric flocculation, study The low energy consumption environment protection electric flocculation treatment process of comprehensive decontamination effect can be reached and its be matched to high-concentration suspension waste water by developing one kind Cover the integrated electric flocculation processing unit used.
To achieve the goals above, the technical solution adopted by the present invention are as follows:
A kind of low energy consumption electric flocculation high suspended matter waste water treatment process, which includes following operating procedure:
S1, electric flocculation pretreatment: by high suspended matter waste water to be processed by electric flocculation reaction chamber, and through electric flocculation chamber In electric flocculation component carry out electric flocculation electrolysis processing;
S2, tube settler processing: will be electrolysed that treated that waste water is passed through tube settler chamber interior through electric flocculation again, described Tube settler chamber interior is provided with the tube settler device that several transverse directions equidistantly arrange, the spacing of the tube settler device For 1~10cm, inclination angle is 30~60 °, and the higher suspension fine impurity removed of not flocculating in the waste water is filled in the tube settler After setting surface deposition, bottom of pond is slided under the effect of gravity and is concentrated discharge again, reaches isolation of purified effect;
S3, multi-medium filtering processing: making to enter filtering chamber through overflow through tube settler device treated waste water, and The more medium filter processing inside the filtering chamber is set to get the clear liquid to after handling.
