Description

Power plant's sludge merging treatment system
Technical field
The utility model belongs to technical field of sewage, and in particular to a kind of power plant's sludge merging treatment system.
Background technology
Waste water of heat-engine plant processing has that sub-prime, component, purification hydraulic art are deposited with traditional water supply plant water-purifying process In difference, water for drainage slurry flow is also different.
The general main source of power plant's sludge has:Treating nature water, drainage water, industrial wastewater, desulfurization wastewater, sanitary wastewater, Coal-contained wastewater etc.;
Treatment of Sludge general technology is:The processing methods such as sludge conditioning, sludge condensation, sludge digestion, sludge dewatering.
In the sludge that each system of power plant generates, due to the particularity of certain systems, the sludge of generation need to pass through individually into Row processing, such as coal-contained wastewater, desulfurization wastewater, treating nature water, drainage water, industrial wastewater are required to that Treatment of Sludge is separately provided Device substantially increases input cost and artificial, in daily management also because system is excessively various cause operation it is complicated, It is chaotic.
Invention content
The utility model aim is to provide a kind of power plant's sludge merging treatment system, solves existing sewage disposal system The high technical problem of existing system complex, operating cost.
The technical solution of the utility model is:A kind of power plant's sludge merging treatment system, is characterized in that:Packet Include drainage water treatment unit, Industrial Wastewater Treatment unit, mud pit and centrifugal dehydrator, the drainage water treatment unit and industry Treatment unit for waste water is connected by sludge pipe with mud pit respectively, and the mud pit is connected by slush pump with centrifugal dehydrator.
Preferably, above-mentioned drainage water treatment unit includes chemical settling pond and the mud scraper that is arranged in chemical settling pond.
Further, the moisture percentage in sewage sludge of above-mentioned drainage water treatment unit discharge is 96-97%.
Preferably, above-mentioned Industrial Wastewater Treatment unit includes the first-stage centrifugal machine, two-stage centrifugal machine and air supporting being sequentially connected Machine.
Further, the moisture percentage in sewage sludge of above-mentioned Industrial Wastewater Treatment unit discharge is 98-99%.
The beneficial effects of the utility model are:The utility model is by being arranged at drainage water treatment unit and industrial wastewater Manage unit, and by the two generate sludge is carried out in a shared mud pit water quality with, then directly pass through slush pump It is delivered to progress dehydration and drying processing in centrifugal dehydrator.It can autonomous control as needed by way of sludge merging treatment Moisture percentage in sewage sludge, not only saves the expense of installation settings sludge concentration tank, and significantly reduces system complexity, improves Sewage treating efficiency.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model power plant sludge merging treatment system.
Wherein, reference numeral is as follows:1- drainage water treatment unit, 2- Industrial Wastewater Treatment units, 3- sludge pipes, 4- mud Pond, 5- slush pumps, 6- centrifugal dehydrators.
Specific implementation mode
As shown in Figure 1, the utility model is a kind of power plant's sludge merging treatment system, which includes drainage water process list Member 1, Industrial Wastewater Treatment unit 2, mud pit 4 and centrifugal dehydrator 6, drainage water treatment unit 1 and Industrial Wastewater Treatment unit 2 It is connected respectively with mud pit 4 by sludge pipe 3, mud pit 4 is connected by slush pump 5 with centrifugal dehydrator 6.
More preferably, drainage water treatment unit 1 includes chemical settling pond and the mud scraper being arranged in chemical settling pond. Integrated artistic is using the sludge quantity about 15% that mechanical accelerating purifying feeding lime is newborn and mixed, flocculation aid, and system generates.Pass through Feeding lime breast and the concentrating function for combining mechanical accelerating purifying to carry, the moisture percentage in sewage sludge generated in system is about 96~ 97%.
Industrial Wastewater Treatment unit 2 includes first-stage centrifugal machine, two-stage centrifugal machine and the air floatation machine being sequentially connected.By two-stage After centrifugal clarification and air-flotation process, the sludge quantity that system generates is about the 10% of inflow, and moisture percentage in sewage sludge is about 98-99%.
Drainage water treatment unit 1 and Industrial Wastewater Treatment unit 2 will be passed through treated that sludge passes through sludge pipe 3 respectively It is discharged into a shared mud pit 4, two strands of sludge are about 97~98% through the moisture content and after water quality.
Centrifugal dehydrator 6 generally requires to be not less than 2% to the sludge solid content of defeated feed arrangement, therefore must not in system Sludge concentration tank is set again, and the equal sludge with after in mud pit 4 can be fed directly to centrifugal dehydrator by slush pump 5 6 carry out dehydration and drying processing.Sludge after dehydration and drying be delivered to again dewatered sludge that on-site and other systems generate into Row concentrates subsequent processing.The utility model closes the sludge of multiple systems in the case of sludge quality or close treating capacity class And handle, so as to significantly save Treatment of Sludge input of the power plant in each system, solve the cumbersome predicament of operation and maintenance.
