China is a lack of water country, can utilize Freshwater resources only to account for the world per capita and can utilize 1/4 of Freshwater resources.Along with further developing of industry, urbanization process is accelerated day by day, and the utilization ratio that improves Freshwater resources is imperative.At present, all be defined in the open process in sub-district in a lot of cities, water reuse in just must doing, these water can be used for flushing the toilet, and greening is done landscape water, thereby has been improved the access times of water, has increased to talk the utilization ratio of water resources and alleviated environmental pollution.Water reuse during Shenzhen, cities such as Beijing take the lead in proposing to do, but after much intermediate water reuse system builds up, all cannot well run.Its reason mainly contains 2 points:
The first, the working cost of middle water treatment is too high, and the processing cost of water adds management about 1 yuan in present one ton, by the client difficulty accept;
The second, in middle water treatment, since the moisture percentage in sewage sludge height of biochemical treatment, fortune mud trouble, and the mud that is produced is difficult, the cost of water treatment in directly having influence on.
In wastewater treatment, on the one hand, improve processing efficiency, need a large amount of microorganisms, and a large amount of microorganisms needs a large amount of organism as food; On the other hand, guarantee that water outlet is up to standard, the organic content in that waste water needs low as far as possible, and this just causes a large amount of microorganisms and the water outlet contradiction that formed up to standard.In conventional art, be the dependence increase reaction times to realize reducing the COD in the waste water, caused the consumption greatly of energy like this.In middle water reuse, general wastewater flow rate is little, therefore can make full use of the kinetic energy of wind-force, find that according to the study in reducing the COD process, the wind energy that the COD in early stage 70% consumes only accounts for 30%, 30% the COD in later stage has but consumed 70% energy in degradation process.In middle water reuse, main operating expenses comprises: 1, wind energy expense accounts for 65%; 2, water pump lifting energy and backflow energy cost account for about 10%; 3, sludge disposal expense accounts for about 20%, and 4, the sterilization expense, account for 5%.Therefore the running cost of water reuse in will reducing, wind energy expense and the sludge treatment expense of saving is crucial.
In actual engineering, water Treatment for Reuse during the water that a lot of situations all are hotel, hotel, sub-district building carries out.The land price of a lot of buildings in city is up to every square meter several ten thousand now, and the bottom of building also needs to do parking lot etc.In doing, in the design of water reusing integral equipment, must consider and reduce floor space, convenient management as far as possible.At present microbial film (MBR) technology of exploitation be comparatively ideal in one of water reusing method, MBR technology successfully solved microbial biomass and the processing standard that need reach between contradiction.But MBR technology in actual use, has the cost of investment height, working cost height, shortcomings such as management inconvenience.In the use on ground such as Shenzhen, the cleaning film workload of MBR technology is big, and needs often to change film.
Therefore, on technology of middle water recycle, need develop a kind of, low investment, low operating cost, sludge yield is few, and easily disposes and little technology and the integration apparatus thereof of floor space.
