Description
Technical field
The utility model relates to the equipment of handling to mud in the municipal effluent, specifically how with water in the water-containing sludge and the isolating equipment of mud.
Background technology
Mud is the residues such as floating foam of sedimentable matters such as the organic matter that produces in sewage treatment process of sewage work, microbial bacteria micelle and sewage surface flotation, wherein contain toxic heavy metals such as a large amount of pathogenic bacterias, parasite, pathogenic microorganism, dioxin and arsenic, copper, mercury, chromium, even poisonous, the objectionable impurities that have radionuclide etc. to be difficult to degrade.The mud how further treatment and disposal sewage work is produced is a great problem in environmental protection field, the world today.Because the colloid of mud is inhaled bag water characteristic, causes the moisture percentage in sewage sludge height, volume is big, brings difficulty for stacking and transportation etc.Municipal sludge as arbitrarily throwing aside hill farmland or landfill lack of standardization, will cause huge potential threat as dealing with improperly or processing lack of standardization to ecotope.
Developed country disposes the emphasis of listing efforts at environmental protection in sludge treatment since nineteen nineties, and the traditional method of handling mud is mainly sanitary landfill, burning and heat energy utilization, soil utilization, aerobic-anaerobic digestion etc.Wherein sanitary landfill is simple relatively to equipment requirements, but needs a large amount of landfill places and the trucking costs of mud, easily produces secondary pollution problems such as groundwater pollution and foul smell dissipation; Burning and heat energy utilization technology make full use of the biogas of generation and set up the power house, and its power self-support rate can reach more than 50%, but burning method equipment and working cost costliness easily cause topsoil, and still residual a small amount of belongs to hazardous substance and handles class solid inorganic thing; It is one of main path of disposing of excess sludge that the soil utilizes technology, but and along with the scope of landfill is dwindled gradually, the soil utilization will be a main development trend, also be the comprehensive difficult problem of sludge disposal simultaneously; Since phase late 1980s, developed some new technologies and technology again, carried out sludge digestion, can shorten the residence time of mud in digester, strengthened the stability of mud as ultrasonic wave in developed countries such as Europe, the United States; Utilize earthworm to handle mud; Utilize the high pressure pyrolysis to destroy the jelling structure of mud, mud is carried out mummification, disinfection, this method can reduce the volume of mud, and dried excess sludge can become a kind of valuable agricultural fertilizer, the disadvantage of this method be the initial investment expense and every day institute's energy requirement expense too high.Make a general survey of external sludge treatment method of disposal and comprehensive utilization, general trend from burning and drying progressively be transformed into behind the high-efficiency dehydration again the utilization of resources take method as the leading factor.
China is because the sludge treatment dynamics of investment is little for a long time, early stage sewage work owing to there is not strict mud discharging supervision, generally peels away sewage and sludge treatment unit, pursue wastewater treatment rate unilaterally, simplify as much as possible even ignored the sludge treatment disposal unit; What have is also idle for a long time in order to save the sludge treatment facility that working cost will build up, with the wet mud of not doing any processing arbitrarily transport outward, simple landfill or stacking, cause many big cities the phenomenon in mud besieged city to occur, and begun to spread to small and medium-sized cities, brought totally unfavorable influence to ecotope.
Though China begins to pay close attention to the mud problem at present, but still it is low to rest on the hierarchy of skill, sludge treatment is in the state of serious hysteresis, and main method has concentrated landfill, macerates system compost, anhydration and incineration etc., and wherein concentrating landfill is the main method that sludge treatment is disposed.But for a long time owing to do not have the outer polymkeric substance of bag, mud micelle structure suction Bao Shui and the mud cenobium cellular water of breaking sludge effectively in the sludge treatment disposal process, cause Sewage Plant to handle the back moisture percentage in sewage sludge still up to 78-83%, transportation cost height when causing the mud landfill, landfill land seizure rate is huge, and very easily cause mud return molten, the secondary pollution that causes landfill such as ooze out, influence peripheral ecotope.
Comprehensive above-mentioned treatment process is found: owing to do not crack ECP (wrapping outer polymkeric substance), water-in-oil structure well and form sizeable mud granule, the sludge dewatering index is difficult to drop to below 78%, has influenced the application and the popularization of this Technology.Therefore, preparation NEW TYPE OF COMPOSITE sludge treatment reagent, development of new sludge treatment technique technology becomes the key issue that will solve the sewage plant sludge advanced treatment.
Oxidation technology and coagulation technology are the research focuses of sludge treatment in recent years.Its research contents relates generally to two aspects: promptly mud anticipates and coagulation technology and technology.Its key is to adopt the coagulation flocculation agent to form the suitable mud granule of size on the basis of using controlled wet oxidation technology destruction suction bag water structure, makes it to reach the purpose that removes easily with separate easily suction Bao Shui.But the technical matters of this respect is still immature at present, does not have technological breakthrough in minimizing, stabilization and innoxious each link.For the existing report of the research of this problem, from present research, selection is basic unit, is that skeleton, multilayer shape resin are initiator with the polyamines polyene with the crude phenols resin, and carrying out block polymerization with propylene oxide and epoxy hexane under the effective catalyst effect, to obtain many aromatic rings polyphenol amine stratiform resin type tridimensional network emulsion splitter OX-9 etc. be main.As the influence of research such as Chen Yinguang acid and tensio-active agent to activated sludge dehydration performance, settling property and ESP.Investigate the influence of medicament by the content of measuring polysaccharide, protein, DNA in the dehydration clear liquid to flocculating settling.Thereby experimental result shows surface properties by change mud flco of acid and tensio-active agent, has reduced mud flco content, discharges dewatering and settling property that water-in-oil has improved mud.Novak etc. studied iron ion in decision flco structure and dehydration characteristic effect, especially iron ion and biological enzyme in protein interactions.They point out that protein is removed in the solution when iron ion increases.This also causes mud CST to reduce, and helps sludge dewatering.In the coagulation technology of sludge treatment, the use composite flocculation agent/or claim that the research of coagulation agent is more, its kind mainly contains: 1) inorganic flocculating agent mainly contains molysite (FeCl
3, FeSO
4Deng and polymkeric substance) and aluminium salt (Al
2(SO
4)
3, AlCl
