Description
Technical field
The present invention relates to technique device that excess sludge is fast and safely processed, particularly to chemical engineering sewage treatment plant, urban comprehensive wastewater treatment plant, the treatment unit of the excess sludge of city domestic sewage treatment plant, adopt this device to carry out fast above-mentioned sewage plant excess sludge, safety, energy-conservation processing and disposal, to solve the problem of the secondary pollution that excess sludge causes environment in the transfer process, and needed expense when reducing the expense of sludge disposal and water-containing sludge dehydration, after the residue water-containing sludge of Sewage Plant is processed through this treatment unit, can realize the purpose of mud decrement.
Background technology
The end from the eighties in last century to Eleventh Five-Year Plan, wastewater treatment in China factory quantity is increased to nearly 3000 by 37, has also brought the difficult problem of ﹠ Mud in the time of the Sewage Plant eruptive growth.At present China only have more than 50 Sewage Plant when founding the factory auxiliary construction the sludge digestion device, wherein only have again more than 20 sludge disposal really to play a role.Mud besieged city confusion is difficult to solve, and the technological line battle grows in intensity especially, anaerobic digestion, mummification, burning, compost, and the quality of each large technique is endured dispute equally to the fullest extent.Solve the confusion of ﹠ Mud industry, what need is not only carrying out of relevant policies, more too busy to get awayly abandons amusement effect, hardheaded improvement, and it is perfect to promote industrial chain, seeks the market binding site, recycling that just might real realization mud.
Present domestic sludge of sewage treatment plant mostly adopts the sanitary landfill mode to dispose, and it is burning, sanitary landfill, compost, drying particles and throwing sea etc. that external many countries adopt more method to sludge disposal.
Burning method: burning method is a kind of method for sludge treatment, also is a kind of mud, utilizes bioenergy heating abundant in the mud, mud is reached farthest subtract appearance.In the burning process, the germ pathogenic agent is thoroughly killed, and poisonous and hazardous organic residue is decomposed by thermooxidizing.Burning ash can be used as the raw material of producing cement, and heavy metal is fixed in the concrete, avoids it to reenter environment.The advantage of sludge incineration is that adaptability is strong, the reaction times is short, floor space is little, level of residue is few, has reached the fully purpose of sterilization.The shortcoming of this method is complex process, and one-time investment is large; Number of devices is many, and operational administrative is complicated, and energy consumption is high, and operational management expense is also high, and there is the “ dioxin in burning process " potentially dangerous of pollution.
Health is filled up method: sanitary landfill is that dewatered sludge is transported to sanitary filling field with municipal wastes, and the technique by the sanitary landfill operation is disposed common are two kinds of anaerobism and double oxygen sanitary landfill.Sanitary landfill method disposes that to have treatment capacity large, reduced investment, running cost is low, and is simple to operate, convenient management, to advantages such as mud are adaptable, but also have take up an area large, the shortcoming such as percolate and odor pollution are heavier.
The compost process: the sludge drying granulation process is more noticeable trend in recent years.In general, the sludge drying granulation process is that the direct soil of mud utilizes a kind of transition before technology is popularized.Mud ball behind the drying particles can be used as fertilizer, soil improvement agent and fuel, and is of many uses.But exist bacteriophage and be transferred the environmental health problem that spreads.
By above-mentioned illustration as seen, from ecotope, economize the land resource or investment construction, operation are considered, research and development have extremely important realistic meaning and social effect to the fast, efficient, safe treatment unit of excess sludge.
The inventor is by utilizing micro-current electroanalysis direct oxidation technology, for characteristic and the characteristics of excess sludge carry out conscientiously, effectively research and development, use this device to subtract appearance to excess sludge substantially, realize the purpose of mud decrement.
