Description
Technical field
The utility model relates to biotechnologies to administer sludge technology field, and specifically a kind of municipal sludge improvement is set
It is standby.
Background technique
With the development of social economy and urbanization, the generation of municipal sewage and quantity are constantly increasing.According to related pre-
It surveys, China's municipal sewage amount can also increase by a fairly big margin for 20 years in future, and quantity of wastewater effluent is up to 4.4 × 1010m3 within 2010
d-1.Currently, China produces the nearly 3 × 106t of dewatered sludge, with the development of domestic sewage disposal cause, total place of sewage treatment plant per year
The continuous expansion and raising, generated sludge quantity for managing water and degree for the treatment of also will increasingly increase.A large amount of sludge fails
Become sewage treatment plant's heavy burden to timely, reasonable processing.
Also contain a large amount of N, P, K, Ca and organic matter in sludge, and N, P can have based on organic with slow release
There is long-term effect.Sludge is useful living resources, as can rationally utilizing can not only then turn waste into wealth, moreover it is possible to increase economic benefit,
So disposition is effectively treated and is had important practical significance using the technology of sludge.
Ingredient, characteristic and the classification of municipal sludge
Sludge is the product of sewage treatment, and ingredient is very complicated, it include the silt particle being mixed into sanitary sewage or industrial wastewater,
The solid particles such as fiber, plant and animal residues and its floccule of condensation, the zoogloea formed by multiple-microorganism and its absorption
The integrated solid materials such as organic matter, heavy metal element and salt, a small amount of pathogenic microorganism, parasitic ovum [4].Sludge it is main
Characteristic is that moisture content is high (up to 99% or more), and it is smelly to be easy corruption for high organic content, and particle is thinner, specific gravity compared with
It is small, it is in colloidal liquid.
The classification method of sludge has very much.By the property of sludge, organic sludge and sediment can be classified as；By the place of sewage
Reason method can be divided into: 1. primary sludge 2. activated sludge 3. humus sludge 4. chemical sludge；The different generation stages according to sludge
Can be divided into: 1. 2. 3. 4. 5. dehydration and drying sludge dries sludge to thickened sludge to primary sludge for digested sludge.
Sludge wet oxidation process, there are high temperature and pressure, and the device is complicated, the high drawback of operation and maintenance cost；Dealing with earthworm
Sludge obtains organic fertilizer by earthworm purified treatment, but exists and cover an area of, handle in time length and treated earthworm body
Enriching heavy metal, membrane bioreactor, purification is more thorough, but there are the blockings of film and membrane material price problem to limit the party
The popularization and application of method；Sludge acidification, basic principle are will to return in waste water treatment system together after excess sludge hydrolysis acidification
Metabolism, to achieve the purpose that reduction or substantially without mud discharging, this method is in the exploratory stage；Sludge artificial wetland treatment
Technology is the new technology studied, still can not be applied on a large scale, sanitary landfills is easy to operate, and investment cost is smaller, processing
Expense is lower, adaptable, but its appropriation of land is serious, if seepage control technique is inadequate, will lead to potential soil pollution and
Underground water pollution；Sludge incineration, treatment facility investment is big, and processing cost is high, while organic matter burning can generate noxious material；It is dirty
Mud throws sea, this is a kind of processing method easy to operate and economic, and still, with the reinforcement of eco-environmental evolvement, people are more next
Concern sludge throws sea to marine eco-environment influence that may be present more, and national governments launch respectively policy stopping throwing sea and control
It is dirty.
