Abstract
The present invention provides a kind of control method of dispersed sludge control source emission reduction, it is primarily characterized in that to be according to sludge constant convergence consumption and sub-prime control principle, disperse to build the clear row's treatment facility of scum silica frost sediment sub-prime concentration in city, dual treatment transfer pond as dispersed sludge, transfer and dual treatment septic tank cleaning waste, sewage, degradable suspended sludge, floating sludge, sediment sludge are by dual treatment.The invention in city by building the dispersed sludge dual treatment transfer facility of application, dispersed sludge from source control process city, optimizes waste environmental sanitation service, reduces waste environmental sanitation workload, prevent the secondary pollution of sludge, reach the effect of the control source emission reduction to dispersed sludge.
Description
Technical field
The present invention relates to a kind of method of Treatment of Sludge.
Background technology
Sludge is the concentration pollutant separated from sewage, and septic tank is the sanitary sewage pretreatment in pollutant source
Facility, and basic sludge anaerobic treatment facility, at least pollutant of 50-60% in usual septic tank retention sewage, change excrement
Pond have the characteristics that a little it is more, wide, scattered, amount it is big, septic tank waste belongs to dispersed sludge, is source contact scar thing, according to
China's septic tank national standard, the clear of septic tank waste draw the cycle as 90 days, 180 days, 360 days, from the angle of prevention and cure of pollution, clearly
The septic tank waste drawn must carry out processing disposal, but be up to 97-99% due to drawing the moisture content of waste in septic tank clearly, and
And be the mixing sludge of new and old sludge, organic composition is big, and it is big to draw treating capacity and the freight volume of waste clearly, haul distance farther out, transport
And processing cost is high, in environmental sanitation processing and sludge treatment facilities deficiency, be concurrently in charge of difficulty it is big in the case of occur and arrange, throw aside steathily
Phenomenon, causes secondary pollution problem.According to the law of indestructibility of matter, pollutant will not disappear without reason, so pollutant " where,
Where " be prevention and control pollutant emphasis, it is main according to sludge constant convergence consumption principle and sludge system state model, sludge system
Having has the characteristics that the degradable sludge that weighing apparatus is held back and the stabilisation sludge two parts that can be accumulated, and the container of degradable sludge consumption is empty
Between, be both degradable sludge " where " space, and degradable sludge be finally degraded to small molecule and " where " source
Head.Under sludge constant convergence consumption state, the unit interval degraded output degradable sludge quantity equivalent to the unit interval input can
Degraded sludge quantity, but can accumulate the accumulation of sludge and take vessel space can destroy the balance of degradable sludge input and output,
It need to can accumulate sludge part and draw discharge clearly.Sludge has three kinds of suspended sludge, floating sludge, settled sludge states, suspended pollution
For thing mainly in sewage, it is the sludge progressively accumulated with the time to float sludge and settled sludge, according to sludge feature accumulation
Property floating sludge and settled sludge sub-prime concentration draw discharge clearly, be management sludge system effective Mitigation options.Sludge is dense
The pollutant of contracting, dispersed sludge are the sources of pollutant, and total amount is big, using sludge constant convergence consumption and sub-prime control technology, just
It is the control source emission reduction of management and control dispersiveness sludge.In septic tank waste component composition, biodegradable component accounts for the overwhelming majority, can accumulate
The quantity of sludge is relatively few, is separated if this part only can be accumulated sludge, it becomes possible to avoid degradable sludge with can
Accumulation sludge mixes, and the clear of waste is greatly reduced and draws, transport, handling disposal amount.Waste environmental sanitation mould generally used now
Formula be by septic tank it is clear draw waste and be transported to night soil-treatment factory handled, about 3-5 cubes of the volume of septic tank cleaning car, and
The volume of one septic tank generally few then more than ten cubes, at most up to a hundred cubes, night soil-treatment factory distance is remote, every to draw processing one clearly
Septic tank is, it is necessary to several train numbers or tens train numbers, so drawing the cost of septic tank environmental sanitation processing clearly according to normal mode very
Height, load is very big, if taking dispersiveness distribution, setting to handle the transfer processing that can accumulate scum silica frost sediment nearby in city
Facility, is the measure for cracking waste environmental sanitation problem.There are the septic tank of huge number in China various regions, and septic tank is inherently a kind of
Anaerobic Treatment facility, this is a kind of space resources of huge consumption organic pollution.Due to the product technology of traditional septic tank
Problem, it is impossible to meet the technical purpose for realizing sludge constant convergence consumption and sub-prime control, just cause the quilt of present environmental sanitation treatment for cow manure
Dynamic situation.Further, since public land is limited be subject to various factors in city, it is impossible to ensures just to meet to build transfer processing pond
Needs, solve the problems, such as that this approach can be by building dual treatment consumption pond, using occupying in newly-built construction project
The dual treatment consumption pond built in people's cell or grassroot project, shares the burden in the public environmental sanitation dual treatment transfer pond in city.
Therefore, the technical measures for taking sludge constant convergence consumption and sub-prime to control, carry out vectorial management, according to city from the source of pollutant
The actual conditions of middle dispersiveness sludge, the mode being combined using septic tank with waste dual treatment transfer pond, source is strengthened dirty
Mud consumption prevention, process auxiliary sludge sub-prime control, management sludge where and where the problem of, from sludge source into
The prevention of row control source emission reduction.
The content of the invention
This purpose invented in fact is that design one kind dispersiveness in city sets the clear row's processing dress of scum silica frost sediment sub-prime concentration
Put, the sludge control source emission reduction control method of the dispersed septic tank waste of processing is tackled with dispersed muddy water dual treatment transfer pond.
The control method of dispersiveness sludge control source emission reduction of the invention is the muddy water dual treatment that dispersiveness is built in city
Transfer pond simultaneously incorporates city waste environmental sanitation workflow, dual treatment, the dispersed septic tank excrement of transfer correspondence reason environmental sanitation clearing
Dirt, each muddy water dual treatment transfer pond handles the septic tank waste of a certain range or scale nearby, first according to urbanization excrement
Pond is distributed and the usable condition of city public land, and in city, different geographical distribution is built, public and private intersection builds scum silica frost sediment
The clear row's treatment facility of sub-prime concentration, as the muddy water dual treatment transfer pond of dispersed sludge, the clear row of scum silica frost sediment sub-prime concentration
The outlet pipe connection municipal sewage pipe network or sewage treatment facility for the treatment of facility, set when scum silica frost sediment sub-prime concentrates clear row's processing
The septic tank applied in transfer processing service range reaches waste and draws timing node clearly, clear using septic tank cleaning equipment or fecal suction truck
