Description

The wastewater treatment equipment of complete set of equipments is repaired in soil heterotopic drip washing
Technical field
This utility model belongs to contaminated sites recovery technique field, refers in particular to soil heterotopic drip washing and repairs complete set of equipments Wastewater treatment equipment.
Background technology
Soil is the basic eco-environmental elements constituting natural ecosystems, is also the things depended on for existence and development of the mankind Matter basis.Along with the mankind's activity aggravation to natural environment influence, produced during people's productive life Pollutant enter soil possibly through various approach, and exceed receiving and the detergent power of soil, thus lead Cause soil natural functional disorder and soil quality deteriorates, and then neighbouring human body and surrounding enviroment may be produced Raw serious harmful effect.Therefore, it is necessary to take rational technological means to carry out contaminated soil remediation, thus Effectively control health and Ecological Environment Risk that soil pollution causes.
Soil heterotopic drip washing will be transferred in the reactor of ground from contaminated area by contaminated soil, utilizes Water or other eluent, acted on by chelating, solubilising, precipitation etc., separates soil pollution component or by soil In pollutant be transferred to liquid phase, then the technology that the leacheate containing pollutant is processed.Soil heterotopic drenches Washing and belong to physical/chemical recovery technique, the polluter that can be used for processing includes that heavy metal and half volatile are organic Pollutant, difficult volatile organic contaminant etc., have and effectively reduce soil pollution substrate concentration, flexible operation, Process control, the advantages such as reparation speed is fast.
According to current existing research and application, soil heterotopic drip washing is repaiied for big particle diameter rank contaminated soil The most more effectively, the pollutant in gravel, medium-fine sand and similar soil are easier to be cleaned by out, and glue Property the most difficult cleaning of pollutant in small particle rank soil such as soil.Generally there is soil in existing drip washing equipment Quality is poor for applicability, it is single to repair pollutant, drip washing device systems is numerous and jumbled, manipulation strength is high, water consumption And the problem such as displacement is big.
Summary of the invention
Main purpose of the present utility model is for soil heterotopic drip washing in small particle rank soil pollution reparation During deficiency on waste water treatment process, it is provided that a kind of soil heterotopic drip washing is repaired at the waste water of complete set of equipments Reason device.
The purpose of this utility model is achieved in that
The wastewater treatment equipment of complete set of equipments is repaired in soil heterotopic drip washing, including the waste water connecting clear liquid collecting tank Regulating reservoir, the waste water after regulation homogenizing pumps into waste water reaction pond and carries out dosing chemical reaction, and waste water reaction pond is even Connect tube settler, tube settler through mud-water separation, output supernatant, output precipitating sludge enter to Mud collecting pit.
In the wastewater treatment equipment of complete set of equipments is repaired in above-mentioned soil heterotopic drip washing, described described waste water Reaction tank includes pH regulator cell, chemical reaction units lattice, coagulation cell and flocculation unit lattice, and pH adjusts Blender difference it is equipped with in joint cell, chemical reaction units lattice, coagulation cell and flocculation unit lattice Adding acid/base, reactant, coagulant, flocculant, under the effect of blender, medicament is the most mixed with waste water Splice grafting touches, and pollutant separate with waste water under pharmacy effect, and according to adding the difference of medicament, this element both may be used Process heavy metal contaminants, organic pollution can be processed again.
In the wastewater treatment equipment of complete set of equipments is repaired in above-mentioned soil heterotopic drip washing, described tube settling The precipitating sludge in pond enters mud collecting pit by gravity, by screw pump, collection mud is pumped into described plate subsequently Frame pressure filter carries out sludge dewatering, and the mud cake produced after dehydration is disposed as hazardous waste outward transport.
Workflow of the present utility model is as follows:
(1) waste water process: the dehydration clear liquid of centrifugal dehydrator by transport pump to wastewater equalization pond, through toning Pumping into waste water reaction pond after joint homogenizing and carry out dosing reaction, water outlet gravity in waste water reaction pond flows into tube settler, Through mud-water separation, supernatant flows into dosing/discharge bay, and precipitating sludge enters mud collecting pit.According to adding The difference of medicament, this treatment unit for waste water both can process heavy metal contaminants, can process again organic pollution.
(2) Treatment of Sludge: the precipitating sludge of tube settler enters mud collecting pit by gravity, subsequently by Collection mud is pumped into filter press and carries out sludge dewatering by screw pump, and the mud cake produced after dehydration is as danger Refuse outward transport is disposed.
This utility model highlights and useful having the technical effect that compared to existing technology
This utility model wastewater treatment equipment is applied widely, operating flexibility big, both can process and give up containing heavy metal Water, can process again containing organic wastewater, and processed waste water both in elution circuit and can utilize remnants by direct reuse Eluent effective ingredient, after waste water can being carried out advanced treating again, reuse or bank of tubes of receiving are put, it is ensured that whole Elution circuit both can make to be applicable to the reparation of organic polluted soil, is applicable to again repairing of heavy-metal contaminated soil Multiple, and water consumption and wastewater discharge can be reduced.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings: see Fig. 1,
The wastewater treatment equipment of complete set of equipments is repaired in soil heterotopic drip washing, including connecting the useless of clear liquid collecting tank 1 Water regulating reservoir 2, the waste water after regulation homogenizing pumps into waste water reaction pond 3 and carries out dosing chemical reaction, waste water reaction Pond connects tube settler 4, and tube settler is through mud-water separation, output supernatant, output precipitating sludge row Enter to mud collecting pit 5.
