Abstract
The invention discloses a high-concentration sewage treatment device. According to the device, sewage is treated through an anaerobic suspended matter concentration control system and is treated by an aerobic hydrolytic acidification system, wherein the anaerobic suspended matter concentration control system is used for controlling suspended particles in the sewage and reducing the treatment load of the subsequent aerobe treatment system. The sewage treatment method comprises the following treatment steps of: removing large-particle suspended matters in a grit chamber; finishing primary precipitation in a primary settling tank; performing aerobe treatment in a biological treatment tank; and performing solid-liquid separation in a secondary settling tank. The sewage treatment efficiency of the high-concentration industrial wastewater is improved, and the environment of a sewage treatment plant is improved.
Description
Technical field
The invention discloses a kind of device for treatment of high-concentration dirt water, belong to sewage treatment area.
Background technology
Present high-concentration waste water all is to adopt the biochemical treatment organic solvent, but this processing mode generally can only be processed COD, DOD content at the waste water below 50,000, then can't be with thinking of a way processing for the waste water of 200,000 above COD, DOD content, because wherein the boiling point of organic solvent is higher, adopt the treatment process that adds the medicament mode, not only cost is high, and can't effectively remove.Much more the acidication treatment process of waste water has research at home and abroad as Biological Pretreatment Techniques and uses.It can improve the sewage biochemical property, reduces the subsequent biological treatment load.Therefore, how in conjunction with prior art, the design high efficiency, low cost is processed sink drainage and the method that contains high-proportion industrial waste water, is the target of technician's concern always.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of device for treatment of high-concentration dirt water, this device is that sewage is processed the then aerobic acidication of process system processing through anaerobism concentration of suspension Controlling System first; Wherein, anaerobism concentration of suspension Controlling System is used for control sewage suspended particle, reduces follow-up aerobe treatment system processing load.Sewage water treatment method of the present invention comprises following treatment step: settling pit is removed the macrobead suspended substance; Preliminary sedimentation tank is finished preliminary sedimentation; Biological treatment tank carries out aerobe to be processed; Second pond carries out solid-liquid separation; Improve the sewage treating efficiency of high-concentration industrial-water, improve the environment of sewage work.
The technical solution used in the present invention is: the present invention includes the anaerobism concentration of suspension Controlling System oxygen hydrolysis acidifying system that becomes reconciled; Then sewage processed through anaerobism concentration of suspension Controlling System first, and the aerobic acidication of process system processes; Wherein, anaerobism concentration of suspension Controlling System is used for control sewage suspended particle, reduces follow-up aerobe treatment system processing load.
Apparatus of the present invention also comprise preliminary sedimentation tank, second pond, sterilization tempering tank, described anaerobism concentration of suspension Controlling System is one to be built-in with the settling pit of biologic packing material, described aerobic acidication system is an aerobic hydrolysis acidification pool, and this aerobic hydrolysis acidification pool is combined into by aerobic contact biological filter and good oxygen hydrolysis fluidized-bed; Sewage inlet links to each other with settling pit, and the settling pit water outlet connects biological treatment tank, and the biological treatment tank water outlet links to each other with second pond, and second pond connects the sterilization tempering tank, and the sterilization tempering tank arranges system's water outlet and mud relief outlet.
