Description
Technical field
The utility model relates to a kind of sludge press filtration dehydration treatment equipment, relates in particular to the multistage hybrid technique device of a kind of Sludge Chemical Conditioning.
Background technology
The at present domestic van-type plate and frame diaphragm filter press that more generally adopts carries out the sludge dewatering treatment technology generation for traditional sludge solid-liquid separation techniques such as original centrifugal dewatering of sludge, vacuum suction filter dehydration, belt filter press dehydrations, makes moisture percentage in sewage sludge reach the emission request of national regulation.
Solids in the mud mainly is made up of the electronegative colloidal solid of wetting ability, because PM for particulate matter is tiny and inhomogeneous, sludge water and sewage sludge solid particulate bonding force are very strong, and be bigger than resistance, so dewatering is relatively poor.In order to improve the performance of sludge dewatering, improve the effect of mechanical dehydration, need change the physico-chemical property of mud through conditioning, reduce the avidity of colloidal solid and water, for solid-liquid separation creates conditions.Sludge conditioning mainly comprises chemical conditioning, the temperature difference is modified and the mikrobe flocculation is modified.
Chemical conditioning is to use maximum mud hardening and tempering methods at present.Its ultimate principle is the amendment that can play electrical neutralization or adsorption bridging effect through in mud, adding; Like coagulating agent, flocculation agent, coagulant aids etc.; Destroy the stability of mud colloidal solid, make to assemble each other between the dispersive small-particle to be split into macrobead, thereby improve the dehydration property of mud.
The amendment that adds in the chemical conditioning process can be divided into pressed powder, liquid on form; Amount by a certain percentage is transported in the sludge conditioning pond that whipping appts is installed quantitatively mud and mixes to reach and change the mud structure through directly adding or process the emulsion dosing method; Strengthen flco intensity; Destroy colloidal stability, thereby improve the purpose of the dehydration property of mud.
Generally adopt in the present domestic sludge press filtration dewatering process: the powdery amendment directly adds with powdery amendment emulsion and adds two kinds of addition methods.
Cause dust from flying to pollute production environment easily owing to directly add the powdery amendment, increase sludge conditioning pond whipping appts structure and power, cause incomplete mixing to influence conditioning effect easily.Emulsion add be with the powdery amendment through with the emulsion addition method that is mixed and made into certain proportion concentration of liquid; Existing domestic and international mud generally adopts tap water or middle water and powdery amendment to be mixed with emulsion to carry out addition method with pump delivery again; Device structure is complicated and huge; Investment, place, working cost increase; The extra increase water yield causes follow-up filter-press dehydration operation hours to prolong, and the solid-liquid separation load strengthens, and the heat that the former water chemistry reaction of powdery amendment and mud is produced in the preparation emulsion process is to the modifying function forfeiture of enzyme in the mud.It is the loss that improves sludge conditioning effect, reduction amendment, the determinative of accelerating follow-up mechanical dehydration speed, reduction working cost that amendment mixes with mud full and uniformly.
