Description
Technical field
The present invention relates to technical field of sewage more particularly to a kind of frame dehydration to be commented with the optimization of sludge conditioning medicament
Valence method.
Background technology
Treatment of Sludge is the important component of sewage disposal, with the continuous improvement of China's level of urbanization, China city
Town sewage treatment capacity steps up, and ends in June, 2017, and the town regenerated water factory rules and regulations mould that China puts into operation reaches more than 4600
Seat, sewage load reach 1.78 hundred million ton days.For a long time, the processing of sewage is the emphasis that everybody pays close attention to, and to the place of sludge
Reason disposition develops slowly.In recent years, as the increase of sewage load, sludge yield also increase year by year, Treatment of Sludge situation is non-
Chang Yanjun.The sludge that municipal sewage plant generates at present mainly uses landfill stabilization, such as natural desiccation of other methods of disposal, heap
The proportions such as fertilizer, burning are less, the sludge treatment easily secondary pollution caused by storing or is mishandling.
The disposition principle of sludge from wastewater treatment plant is：Innoxious, minimizing, stabilisation and recycling.It is wherein harmless
Change refers to killing the pathogenic microorganism and parasitic ovum in sludge, the safety of utility process by way of sterilizing
Health；Minimizing refers to so that sludge volume is reduced by mud decrement, and form is converted into solid-state by liquid, reaches at reduction
The purpose of reason and transportation cost；Stabilisation refers to so that sludge is reached stable state by physical or chemical treatment, does not continue to drop
Solution avoids that secondary pollution occurs；Recycling refers to being used as agricultural fertilizer or soil improvement soil etc. after carrying out processing disposition to sludge
Aspect achievees the purpose that the utilization of resources.
Urban sewage treatment plant sludge handles typical process：At sludge condensation, sludge digestion, sludge dewatering and sludge
It sets.According to CJT309-2009《Urban sewage treatment plant sludge disposes agricultural shale》,CJT362-2011《Urban wastewater treatment firm
Sludge treatment forest land shale》The requirement of equal files, sludge treatment moisture content need to reach 60% and it is following when could be used for correlation
The utilization of resources in field.Sludge dewatering is to influence an important step for moisture percentage in sewage sludge, will directly affect the effect of sludge treatment.
Current common sludge dehydration device has belt filter press, centrifugal dehydrator, frame dehydration machine etc., and wherein plate and frame filter press is because of it
Dewatered sludge solid content can be maintained at a higher level, and technique has quite been improved and maturation, in actual production
In be widely used.
It is the important step before frame dehydration that sludge dosing, which carries out conditioning, and sludge conditioning effect will directly affect generation mud cake
Moisture content.Wherein sludge conditioning medicament is divided into organic medicament and inorganic medicament two types.And organic medicament and inorganic medicament
In active principle content, dosing method, dosing rate (handle single ton of dry mud added medicament dry weight), medicament unit price etc.
There are larger differences, cause the very big inconvenience of quantization and comparison Treatment of Sludge effect and processing cost.Therefore, both inhomogeneities
The comparative evaluation of type medicament is a problem.
Invention content
It is an object of the invention to：When overcoming sewage dehydration in the prior art, at different type sludge conditioning medicament
Technical difficulty existing for the overall merit of effect and cost is managed, a kind of optimizing evaluation of frame dehydration sludge conditioning medicament is provided
Method, it is convenient, objective with evaluation method, it can preferably go out sheet frame dehydration effect to meet production requirement, synthesis
The advantages that processing cost is relatively low, optimum choice to effectively solve the problems, such as different type and treatment effect medicament.
In order to achieve the above object, the present invention adopts the following technical scheme that realization：
A kind of optimizing evaluation method of frame dehydration sludge conditioning medicament, the optimizing evaluation method include the following steps：
Step 1)：Verification conditioning medicament negativity index, the medicament negativity index, which includes moisture content of the cake, to be met
Board and frame machine inputiing mud volume must meet and be more than or equal to after must meeting 5.5-8.5 less than or equal to 60%, mud cake pH, add sheet frame conditioning medicament
50m3, board and frame machine must meet the processing requirement of at least four batch daily；If above-mentioned negativity index can meet, sheet frame
The treatment effect of conditioning medicament can reach the requirement, carry out step 2)；It cannot if above-mentioned negativity index appearance is at least one
It when meeting, is then directly evaluated as unqualified, i.e., directly negates the medicament；
Step 2)：Combination processing cost carries out overall merit to sheet frame conditioning medicament, and the test period of each medicament is determined
It is one week, does not consider influence of the environmental factors such as temperature change to pilot production during short-period test；In view of sheet frame
The case where being added respectively there may be two kinds of medicaments in dehydration, if two kinds of medicaments are respectively " medicament 1 " and " medicament 2 ", such as
Only a kind of medicament, then the numerical value of " medicament 2 " relevant parameter is with 0 substitution calculating；By different disposal effectiveness indicator to cost
Influence consider the comprehensive cost of single ton of dry mud " processing " among, to which comparison obtains the optimal conditioning medicine of overall merit
Agent.
As advanced optimizing for said program, the comprehensive cost of single ton of dry mud of processing includes following calculating step：
