Description

A kind of sludge modification deep dehydration processing means

Technical field

This utility model relates to sludge dewatering treatment device, particularly to a kind of sludge modification deep dehydration processing means.

Background technology

Along with the quickening of Urbanization in China, treatment rate of domestic sewage improves year by year, the mud of municipal sewage plant Yield also sharply increases.After entering environment such as mishandling mud, bring secondary pollution directly can to water body and air, one Municipal sewage plant, Treatment of Sludge cannot give full play to it and eliminate the effect polluting protection environment, the most also will be to life State environment and mankind's activity constitute serious threat, and along with improving constantly of whole world mud generation amount, specific resistance to filtration is gradually Become domestic and international focus of attention.From 20 century 70s, including physics, chemistry, biology and method associated with it to dirt The research report that mud carries out processing starts in succession to occur, Physical mainly have pyrohydrolysis, freeze thawing treatment, ultrasound wave, electron beam, High-pressure spray and ball milling etc.；Chemical method mainly has Fenton, wet oxidation process, acid-alkali treatment, Ozonation, hydrogen peroxide oxidation Method etc.；Bioanalysis mainly has high-temperature micro-aerobic digestion, high temperature aerobic digestion etc..Wherein, physics, chemical method and combination measure thereof are big Multipotency is greatly improved sludge digestion performance, but in terms of present circumstances, its processing cost is higher, and operation easier is big, applies from reality Still have relatively large distance, although and bioanalysis pretreatment also has similar effect and operating cost is relatively low, but existence process the time relatively The shortcoming such as long, inefficient.

Abroad, the research report about being dehydrated different types of industrial sludge is more.Such as M.Kaiser etc. People finds that particular kind of surfactant, in coal sludge system, reduces the surface tension of water, decreases water simultaneously Molecule is at the energy of adsorption on mud granule surface.Solid-liquid separation efficiency can be improved in the case of additional dewatering type is identical；By the moon When ionic surfactant and flocculant compound use, surface tension can be dropped to lower value.And add cation or the moon from Subtype surfactant all can reduce the moisture content of centrifugal rear mud cake.Thus, it could be seen that can surfactant effectively reduce interface Tension force, is that can it be applied to sludge dehydration process and obtain the key of good result.The result of study table of S.J.Puttock et al. Bright, surfactant is applied in different types of mineral sludge dewatering, after all making filtration, sludge cake moisture content is notable Decline.M.J.Pearse and A.P.Allen is it also hold that surfactant is added in mineral mud to improve ore deposit as auxiliary agent The dewatering of thing mud, decreases the moisture content of sludge filter cake.C.Huang et al. points out, adds before adding flocculant A certain amount of surfactant carries out conditioning process to alum sludge, can substantially reduce the resistivity of mud, ties in minimizing system The content of Heshui, can improve filtering rate simultaneously, improve dehydrating effect.C.P.Chu et al. is found through experiments, at alum sludge Middle interpolation cationicsurfactants can improve the strainability of mud.

China's water treatment technology development is very fast, and little with international most advanced level gap, wherein sludge dewatering technology is also It is enhanced, but still there is a certain distance in industrially developed country relatively.The traditional method of sludge dewatering mainly by Sludge drying bed so that it is natural mummification, its major defect is that floor space is big, environmental health inclement condition, area of application scope Little, general sludge dewatering technology can not meet the process requirement of the sludge quantity that sewage treatment plant increases day by day, therefore, as What is greatly improved specific resistance to filtration efficiency, selects suitable processing mode and suitable sludge treatment processing equipment to enter mud Row advanced treating, is the current Main way to sludge dewatering technical research.
