Description

Four-section reverse osmosis system for treating municipal sewage
Technical Field
The utility model relates to a water treatment field especially relates to a four-section type reverse osmosis system who handles municipal sewage.
Background
The traditional domestic sewage treatment system has the problems of high sludge yield, difficult sludge treatment, stink generated in the treatment process, complex equipment, high management difficulty, high investment and the like, and the problems can be effectively solved by the large-scale construction, upgrading and reconstruction of urban sewage treatment plants. A large amount of sewage is generated in the treatment process of the sewage treatment plant, people are limited in understanding sewage regeneration of the sewage treatment plant, a water resource market is difficult to form, and development and utilization of water resources are limited. With the increasing importance of society on the secondary pollution problem generated by sewage treatment plants, the comprehensive social benefits brought by the discharge of sewage and the continuous deepening of the utilization and development of reclaimed water resources, a new system is urgently needed to solve the key problems of sewage discharge and resource utilization of the sewage treatment plants so as to reduce sewage discharge, increase reuse water and realize water resource utilization and high-quality reuse of municipal sewage.
Disclosure of Invention
In order to solve the technical problem, the four-section reverse osmosis system for treating the municipal sewage is provided and is characterized in that the treatment system comprises a lift pump, a raw water tank, a pre-pressurizing pump, a mechanical filter, a four-section reverse osmosis system and an ion exchanger which are arranged in sequence, pipelines are connected among the devices, filtrate in the pipelines flows in a single direction through a water pump, and the filtrate in the pipelines is conveyed to the next device.
Sewage of a sewage treatment plant enters a raw water tank through a lift pump, and acid is added according to the water quality condition to adjust the pH value to be 6-9; under the action of the pre-booster pump, raw water is filtered by a mechanical filter to remove suspended matters and then enters a four-section reverse osmosis system for concentration and filtration, produced water is filtered by an ion exchanger to remove ammonia nitrogen and then reaches the standard for recycling, and concentrated water enters a biochemical system of a sewage treatment plant for continuous treatment.
On the basis of the technical scheme, the mechanical filter is one of a sand filter, a fiber filter or a disc filter.
On the basis of the technical scheme, the four-section reverse osmosis system is a roll-type reverse osmosis system or a disc tube type reverse osmosis system.
On the basis of the technical scheme, the four-section reverse osmosis system comprises an energy recovery device, energy is recovered by supplementing three or four sections of inlet water pressure by recovering the residual pressure of the fourth section of concentrated water, and the energy consumption of the system is reduced.
On the basis of the technical scheme, concentrated water backflow is not arranged in the second section and the third section of the four-section reverse osmosis system, so that the energy consumption of the system is reduced, the highest recovery rate of the system is 90%, and the highest desalination rate is 98%.
Has the advantages that: the utility model provides a four-section type reverse osmosis system who handles municipal administration sewage, it is stable up to standard to go out water, and system operation process energy consumption is low, reduces sewage discharge, increases sewage reuse water volume up to standard. Apply four segmentation reverse osmosis membrane systems to municipal administration sewage retrieval and utilization, realize sewage resource utilization.

Detailed Description
The four-section reverse osmosis system for treating municipal sewage is characterized in that the treatment system comprises a lift pump, a raw water tank, a pre-pressurizing pump, a mechanical filter, a four-section reverse osmosis system and an ion exchanger which are arranged in sequence, pipelines are connected among the devices, filtrate in the pipelines flows in a single direction through a water pump, and the filtrate in the pipelines is conveyed to the next device.
The specific use method is as follows:
sewage of a sewage treatment plant enters a raw water tank through a lift pump, and acid is added according to the water quality condition to adjust the pH value to be 6-9; under the action of the pre-booster pump, raw water is filtered by a mechanical filter to remove suspended matters and then enters a four-section reverse osmosis system for concentration and filtration, produced water is filtered by an ion exchanger to remove ammonia nitrogen and then reaches the standard for recycling, and concentrated water enters a biochemical system of a sewage treatment plant for continuous treatment.
On the basis of the technical scheme, the mechanical filter is one of a sand filter, a fiber filter or a disc filter.
On the basis of the technical scheme, the four-section reverse osmosis system is a roll-type reverse osmosis system or a disc tube type reverse osmosis system.
On the basis of the technical scheme, the four-section reverse osmosis system comprises an energy recovery device, energy is recovered by supplementing three or four sections of inlet water pressure by recovering the residual pressure of the fourth section of concentrated water, and the energy consumption of the system is reduced.
Compared with a conventional two-section membrane system, the recovery rate is improved by adopting concentrated water internal circulation, and concentrated water backflow is not arranged in the second section and the third section of the four-section reverse osmosis system, so that the energy consumption of the system is reduced, the recovery rate of the system can reach 90 percent, and the desalination rate can reach 98 percent.
