Description
Technical field
The invention belongs to a kind of water quality characteristic test equipment in Treatment of Industrial Water field, more particularly to a kind of body refuse tester
And test method.
Background technology
Treatment of Industrial Water technological process is a process for gradually removing impurities in water, and the removal of impurity follows removal grain size
Rule from big to small, and diameter is referred to as colloid in 0.1 μm or more of substance in water, colloid is made of different-diameter particle
A stabilising system, the removing of colloidal substance then relies primarily on industrial coagulant precipitation equipment, therefore, is set as pretreatment key
Standby coagulant precipitation device is the equipment that water treatment field is most widely used, and coagulant precipitation process is a complicated mass transfer mistake
Journey, the hydrodynamics and kinetic theory for also including complexity mainly disperse including electrolyte mixing, electrolyte hydrolyzes, flocculation, wads a quilt with cotton
Processes, the factors for influencing coagulant precipitation such as solidifying body growth, sedimentation include mainly：Source quality (salt content, basicity), water temperature, water
PH value, electrolytes (being determined by small-scale test), body refuse concentration and activity, coagulation time, equipment size and structure distribution,
Run flow velocity (under predetermined processing), coagulation agent dose etc..It is many for a fixed coagulant precipitation equipment and design water source
In more influence factors water temperature (can be controlled by heater), body refuse concentration and activity, coagulation agent dose can taking human as control,
Wherein, the suspended matter of coagulation agent dose and water, colloidal content and sludge volume determine body refuse concentration and activity, therefore, coagulation
There are certain relevances with coagulation agent dose for agent dose.In actual operation, body refuse concentration and activity, coagulation agent dose usually
The case where being to be controlled by experience, being usually present control lag.
The key of coagulant precipitation equipment operation control is body refuse amount and the active adjustment of body refuse.But currently, without such
The test equipment of type can only use the settling ratio of artificial qualitative test body refuse, and cannot carry out body refuse active testing.Therefore,
The operation of current coagulant precipitation equipment control be it is extensive, there are the problem of mainly have：1) anti-load impact ability is small, far reaches
Less than design requirement；System equipment operation stability is not high, and effluent quality fluctuation is big, occurs the exceeded feelings of delivery turbidity often
Condition；2) dosage adjustment is inappropriate, and dosing dosage is low, and coagulant precipitation effect is poor, and the substances removal effect such as colloid declines, after causing
Continuous system dirt is stifled；Dosing dosage is high, not only increases cost, has also resulted in unreacted coagulant and occurred in follow-up system
Coagulating when especially handling low temperature and low turbidity water, easily causes product (colloid) pollution (ultrafiltration etc. of follow-up system coagulant
Membranous system occurs serious dirty stifled)；3) body refuse discharge is inappropriate, and body refuse discharge capacity is more than actual emission, and effluent quality deteriorates, and is
Nominal output is not achieved in system, and body refuse water content is big, and desliming workload increases, and discharge capacity is less than actual emission, on the one hand meeting
The mixing of activated sludge and water is hindered, on the other hand, can cause to be discharged a large amount of alumen ustum risings, effluent quality can also deteriorate；4) place
When managing municipal middle water, the hardness that may cause in water exceeded in short-term, basicity and ammonia nitrogen, total phosphorus are exceeded, are generated to membranous system
Irreversible harmful effect.
In conclusion the industrial coagulant precipitation processing of water is the key that Treatment of Industrial Water, and body refuse amount and activity control are
Industrial coagulant precipitation handles the key well run, and body refuse amount is more or can all directly affect body refuse activity and waterpower flow less, most
Water quality is caused to deteriorate eventually.Therefore, accurately controlling for coagulant precipitation processing is exactly to get hold of " as soon as degree ", this degree the moment
