Embodiment 1

[0032] please see figure 1 , a system for the treatment of targeted denitrification and dephosphorization resin regeneration waste liquid provided by the present invention, comprising a resin adsorption tank 1, a waste liquid pool 2, a denitrification pool 3, a sedimentation pool 4, a high-density sedimentation pool 5, and a sludge pool 6. Dehydration system 7;

[0033]After the tail water of the sewage treatment plant is treated by the resin adsorption tank 1, the nitrogen and phosphorus elements in the incoming water are adsorbed and removed by the targeted denitrification and phosphorus removal resin 8 filled in it, and the purified water is discharged; After the resin 8 is regenerated, desorbed and washed, the waste liquid generated by the washing and replacement is discharged into the waste liquid pool 2 .

[0034] The regenerated waste liquid in the waste liquid pool 2 is lifted by the lifting pump 9 and then enters the denitrification tank 3. The regenerated waste liqu...

Embodiment 2

[0043] please see figure 2 , a method for the treatment of targeted denitrification and dephosphorization resin regeneration waste liquid provided by the present invention, comprising the following steps:

[0044] Step 1: After the tail water of the sewage treatment plant is treated by the resin adsorption tank 1, the nitrogen and phosphorus elements in the incoming water are adsorbed and removed by the targeted denitrification and phosphorus removal resin 8 filled in it, and the purified water is discharged; The denitrification and phosphorus removal resin 8 uses sodium chloride dosing device 11 to add brine to realize the regeneration and desorption of the targeted denitrification and phosphorus removal resin 8. The concentration of the sodium chloride solution used for regeneration is 8%. The volume of the sodium chloride solution consuming 8% concentration is 1.2 to 1.3 times the volume of the resin adsorption tank 1; after that, the flushing water pump 12 is used to tran...

Abstract

The invention belongs to the technical field of sewage treatment, relates to a system and method for concentrated resin water treatment, and in particular relates to a system and method for treatmenton a targeting nitrogen and phosphorus removal resin regeneration waste liquid. The system for treatment on the targeting nitrogen and phosphorus removal resin regeneration waste liquid comprises a resin adsorption tank, a waste liquid tank, a denitrification tank, a sedimentation tank, a high-density sedimentation tank, a sludge tank and a dehydration system. By adopting the system for treatmenton the targeting nitrogen and phosphorus removal resin regeneration waste liquid, nitrogen and phosphorus are firstly effectively enriched, a regeneration waste liquid is treated in combined biochemical and physicochemical treatment modes, and the system has the beneficial effects of being stable in operation effect, high in nitrogen and phosphorus removal efficiency, rapid in reaction speed, highin produced water quality, high in self control degree, small in floor space, capable of effectively solving the problem of secondary pollution of a resin regeneration waste liquid, and the like.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and relates to a system and method for resin concentrated water treatment, in particular to a system and method for targeted denitrification and phosphorus removal resin regeneration waste liquid treatment. Background technique [0002] Nitrogen and phosphorus pollution caused by urban sewage and key industrial wastewater is the main cause of frequent eutrophication in many rivers, lakes and seas in our country. In order to effectively control and improve water eutrophication, the Department of Science and Technology Standards of the Ministry of Environmental Protection is organizing Technical guidance documents such as technical guidelines and specifications for pollution prevention and control of nitrogen and phosphorus removal from urban sewage and key industrial wastewater. In recent years, the Ministry of Environmental Protection has frequently organized seminars on the prevention a...
