Embodiment 1

[0020] Such as Figure 1-Figure 2 As shown, the present invention facilitates the system for filtering the oxidation and denitrification mother liquor, including a recording system and successively connected circulation pools, heat exchangers, cooling towers, filtering devices, concentration towers and evaporation pools, and the oxidation and denitration mother liquor enters the circulation pool, and in the first Driven by the water pump 1, it enters the heat exchanger, and the heat exchanger heats the oxidation and denitration mother liquor from the circulation pool, and sends the heated oxidation and denitration mother liquor into the cooling tower under the action of the second water pump 2, and the cold water The tower cools down the oxidation and denitration mother liquor from the heat exchanger, the oxidation and denitration mother liquor is evaporated and concentrated in the cooling tower, and the concentrated oxidation and denitration mother liquor is sent to the filter...

Embodiment 2

[0027] Each of the filtering devices also includes a one-way valve 7, which is connected to the output pipeline of the bypass filter, and the fluid in the output pipeline can only flow from the bypass filter to the fourth water pump 4.

[0028] Preferably, the concentration tower concentrates the liquid from the bypass filter to 40mol / L.

[0029] Further, the evaporation pond is a square evaporation pond with a flat bottom.

Embodiment 3

[0031] The controller can adopt single chip microcomputer, ARM processor or PLC. Preferred single-chip microcomputer among the present invention, its model is preferably AT89LV51, liquid flowmeter DN10-50, and display adopts LED display screen or digital display screen.

Abstract

The invention discloses a system convenient for filtering oxidative denitration mother liquor. The system convenient for filtering the oxidative denitration mother liquor comprises a recording system,and a circulating pool, a heat exchanger, a cooling tower, two filtering devices, a concentration tower and an evaporation tank which are sequentially communicated, wherein the two filtering devicesare connected in parallel between the cooling tower and a fifth water pump; each filtering device comprises a third water pump and a side filter connected in sequence, and a liquid flow meter is arranged at the output end of the side filter; the recording system comprises a controller, and a display, an LED lamp I and an LED lamp II which are connected with the controller respectively, the liquidflow meter and an electromagnetic reversing valve are in signal connection with the controller, and the controller receives information from the liquid flow meter, displays the information through thedisplay, and simultaneously controls the working states of the LED lamp I, the LED lamp II and the electromagnetic reversing valve. The system convenient for filtering the oxidative denitration mother liquor thus eliminates the need to suspend the entire filtering system to shut down filtering equipment, so that the working efficiency of the entire mother liquor processing system is ensured.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a system for facilitating the filtration of oxidation and denitrification mother liquor. Background technique [0002] Nitrogen is directly discharged into the environment along with the sewage, which will pollute the environment. Nitrogen continues to enter the water body along with the sewage, especially the circulating water body, such as a lake, which can cause excessive growth of aquatic plants and algae due to the eutrophication of the water body, and a series of adverse consequences are derived from this. The oxidation of ammonia nitrogen will continuously consume the dissolved oxygen in the water, and also has a toxic effect on aquatic organisms. Nitrate and nitrite can induce hyperferritinemia and gastric cancer, seriously affecting human health. In order to avoid the nitrogen-containing waste liquid produced in the factory production - the oxidation and denitri...
