Description

A kind of composite sewage treatment equipment
Technical field
This utility model belongs to technical field of sewage, relates to sewage-treatment plant, especially a kind of compound Type sewage-treatment plant.
Background technology
Sanitary sewage is mainly in urban life the various detergents of use, sewage, rubbish, feces etc., many For nontoxic inorganic salts, many containing nitrogen phosphate and sulfur in sanitary sewage, malignant bacteria is many, and its feature shows as Biodegradability is good, concentration of nitrogen and phosphorus is higher, be not the highest containing pathogen, gross contamination substrate concentration, COD, BOD Etc. up to standard easily.Trade effluent refers to waste water and the waste liquid produced in industrial processes, wherein contains with water The pollutant produced in the commercial production materials, intermediate product, side-product and the production process that run off, feature Mainly show as that discharge capacity is big, it is complicated and seriously polluted to form.As can be seen here, sanitary sewage and trade effluent In the polluter kind that contains and quantity the most different, if be not added with distinguishing uses identical sewage disposal device Carry out purification of water quality, on the one hand can not reach discharge standard, on the other hand sewage disposal device is caused damage. Therefore, it is necessary to city domestic sewage and commercial production sewage are carried out classification process.
The utility model patent of application number 201520742305.X, discloses a kind of compound sewage disposal system, Including grid, feed arrangement, stirring pool, catalyst storage pond, biochemistry pool, hyperfiltration treatment pond, anaerobic pond, First sedimentation tank, the second sedimentation tank and tank, grid is connected with feed arrangement, feed arrangement and stirring Pond is connected, and stirring pool is connected with biochemistry pool, and biochemistry pool is connected with hyperfiltration treatment pond, hyperfiltration treatment pond Being connected with anaerobic pond, anaerobic pond and the first sedimentation tank are connected, and the first sedimentation tank and the second sedimentation tank are connected Connecing, the second sedimentation tank is connected with tank, and stirring pool includes stirring pool body and for supporting stirring pool The foot rest of body, stirring pool top connects has catalyst to add pipe, and stirring pool is added pipe by catalyst and urged Agent storage pool is connected.This compound sewage disposal system uses plurality of devices, and segmentation carries out sewage disposal The treatment effeciency of sewage can be improved;But, do not realize different types of sewage is carried out classification process, Still suffer from the problem that sewage compliance rate is low, plant maintenance is difficult during combined sewage processes.
Utility model content
This utility model is for solving the deficiencies in the prior art, it is provided that a kind of composite sewage treatment equipment, with reality Existing trade effluent and the classification of sanitary sewage, the target of qualified discharge.
The technical solution of the utility model is as follows:
A kind of composite sewage treatment equipment, by industry collecting-tank, pretreatment catalytic tower, grid regulating reservoir, Anaerobic pond, anoxic pond, contact Aerobic Pond, sedimentation tank, the front pond of filter, degree of depth filter bed and ultraviolet disinfection tank group Become.Industry collecting-tank is in parallel with grid regulating reservoir after connecting with pretreatment catalytic tower, grid regulating reservoir, anaerobism Depend on before and after pond, anoxic pond, contact Aerobic Pond, sedimentation tank, the front pond of filter, degree of depth filter bed and ultraviolet disinfection tank Secondary cascaded structure combines.
Grid regulating reservoir is two lattice, and front lattice are artificial grid pool structure, and rear lattice are sewage regulating reservoir structure. Sanitary sewage is directly delivered into artificial grid pond by pipeline, through the filtration scavenging action of grid, and will life dirt Float in water is removed, and the organic and inorganic of the now suspension of the bulky grain in water waits material the most substantially to go Except clean.
Trade effluent enters industry collecting-tank through special collection conduit, carries out preliminary sedimentation in industry collecting-tank After, trade effluent supernatant is pumped in pretreatment catalytic tower.Trade effluent, will in pretreatment catalytic tower Heavy metal ion, toxic organic compound carry out oxidation and separate, and then pretreated trade effluent are flowed into grid In rear lattice sewage regulating reservoir in regulating reservoir, mix with the sanitary sewage discharged through artificial grid pond, mixed Close sewage and together flow into anaerobic pond, participate in follow-up identical sewage disposal link.
At the bottom of the pond of contact Aerobic Pond, aerator is installed, by outside roots blower as blast apparatus, with Time, sludge pump is installed at the bottom of pond, the precipitate periodic cleaning at the bottom of pond is pumped into anoxic pond.
Installing sludge pump at the bottom of sedimentation tank, carry out the mud in sedimentation tank reclaiming reprocessing, a part of mud returns Stream directly returns anaerobic pond, and excess sludge carries out sheet frame sludge dewatering.
Sewage flows into from sedimentation tank and filters front pond, enters degree of depth filter bed the most in batches and carries out biofilm filtration, Rear inflow ultraviolet disinfection tank, reaches sewage drainage standard after comprehensive ultraviolet light illumination-based disinfection.
Effect of the present utility model and benefit be:
(1) this composite sewage treatment equipment, reactor uses the mode that parallel connection and serial connection combines, permissible Trade effluent and domestic sewage according to water channel are entered sewage-treatment plant;
(2) the sewage disposal channel after segmentation, can improve the treatment effeciency of all sewage, it is ensured that sewage Compliance rate;
(3) corrosion that sewage-treatment plant causes by heterogeneity sewage etc. is avoided to destroy, beneficially equipment Later maintenance.
