Technical field
The present invention relates to municipal administration and environmental technology field, refers in particular to pillar mud drying equipment and use that a kind of suction pressure combines
Method, more particularly to pollution bed mud drying engineering.
Background technology
With the fast development of Chinese society economy, urban population sharply increases, to city river, the blowdown flow rate day in lake
Cumulative more, water pollution is on the rise, and quality of water environment is worsening, to river course, the dredging in lake, desilting and its processing of bed mud
It is very urgent, the living environment of resident is directly connected to, at present caused sludge number during China lake, river dredging work
Amount has reached surprising degree.The development of mud-water separation technology and equipment is extremely urgent, and its development will directly affect lake, river
The modernization of dredging work and the development process in city, especially large- and-medium size cities He Hu silt up and polluted and had influence on
The international image in China, the solution of this problem, it will obtain obvious environmental benefit and social benefit, how to carry out environmentally friendly clear
The mud become silted up, cleared out how to handle be current international community all inquire into the problem of, if some link handle bad, desilting work
Journey will bring serious, large area secondary pollution, and consequence is hardly imaginable.
Mud subsequent treatment after desilting is a key issue, because not only yield is big for dredging silt, and mechanical property
Matter is poor, moisture content is high, and in fluid state, people only influences desilting process not in time for processing, can also cause secondary pollution, put into practice table
It is bright, it is up to 3 years even if the mud directly cleared out is stacked, surface seems drying, but substantial amounts of water is still contained in inside, does not hold
Carry power, mud transport point ooze out and rain drop erosion caused by secondary pollution it is extremely serious, according to incompletely statistics, China only gives up every year
For the dredging silt abandoned just up to more than 1 billion cubic meter, discarded dredging silt is often placed in land throwing region low laying areas, takes
Some fish ponds and cultivated land, generate very high expense, the funds of China south water to north east line first phase land acquisition just account for work
60% or so of journey total cost, it can be seen that, mud after dredging above all drying and other treatment.
