TECHNICAL FIELD

[0001] The utility model belongs to water recycling technical field relates to domestic water recycling device. BACKGROUND

[0002] Many independent chemical enterprises are generally constructed in the surrounding villages of the city periphery, and there are no urban sewage treatment supporting facilities and no industrial wastewater treatment facilities in the surrounding area. The untreated sewage (whether industrial wastewater or domestic sewage) cannot be directly discharged, which results in that the annual water treatment cost of independent chemical enterprises is a considerable amount.

[0003] After the original design of domestic sewage→integrated treatment device→water pool, the water is pumped to the factory area greening spraying point as greening water. However, in the six months from October to April of the next year in the northern region, spraying and watering are not needed, so the excess water also needs to be discharged and treated. The treated water basically has no odor, but it may contain bacteria, some heavy metals and harmful phosphorus and sulfur components, and therefore cannot be directly used as domestic water. Based on this, a domestic water recycling device is designed. SUMMARY

[0004] The utility model discloses a domestic water recycling device, which aims to solve the problems in the background art.

[0005] The utility model discloses a domestic water recycling device, which aims to solve the problems in the background art.

[0006] In the domestic water recycling device, the active carbon manganese sand filter is composed of two groups of one manganese sand tank and one active carbon tank, and is automatically controlled by the driven bottle head valve. One group is used for use, and the other group is used for backwashing, so that the water production process is not interrupted.

[0007] In the domestic water recycling device, the number of the cation-anion softening bed is two, and the water inlets of the two cation-anion softening beds are provided with water pumps.

[0008] In the above-mentioned domestic water recycling device, the cationic and anionic softening bed and the RO reverse osmosis membrane are provided with a 1.2MPa multi-stage water pump.

[0009] Compared with the prior art, the domestic water recycling device has the advantages that the discharge treatment capacity of the chemical enterprise can be reduced to zero, the operation cost is saved, and the water fee, water resource tax and other costs are reduced; and the water consumption is effectively reduced, the discharge treatment capacity is reduced, and the operation cost is saved. BRIEF DESCRIPTION OF DRAWINGS

[0010] Figure 1 is a flow structure schematic diagram of the domestic water recycling device.

[0011] In the figure, 1 is an integrated sewage treatment device; 2 is a factory greening water pool; 3 is a fire water pool; 4 is a fire water pipe head; 5 is an activated carbon manganese sand filtering element; 6 is a cationic and anionic softening bed; 7 is an RO reverse osmosis membrane element; 8 is an industrial circulating water pipe head; 9 is a chlorinator; and 10 is a domestic water pipe head. DETAILED DESCRIPTION

[0012] The following is a specific embodiment of the utility model and further describes the technical scheme of the utility model in combination with the drawings, but the utility model is not limited to these embodiments.

[0013] As shown in the figure, the utility model discloses a domestic water recycling device; Figure 1

[0014] Embodiment: in combination Figure 1 The domestic water to be treated comes from the integrated sewage treatment device 1, first enters the fire water pool 3, and is used as fire water; another enters the activated carbon manganese sand filtering element after being pressurized by a submerged pump; the activated carbon manganese sand filtering element has four tanks, two manganese sand tanks and two activated carbon tanks, forms two groups, can realize automatic control through a bottle head valve, uses one group and backwashes the other group, and can make the water production process uninterrupted.

[0015] After being filtered by the activated carbon manganese sand filtering element, the water in which iron, silicon and silt are removed enters the cationic and anionic softening bed 6 to remove calcium and magnesium ions in the water; the cationic and anionic softening bed 6 has a special water pump at the inlet, the softening bed can automatically control regeneration and backwashing, one bed is used and the other is standby, one is used and the other is regenerated, and the water production process can be uninterrupted.

[0016] After being softened, the water is pressurized by the 1.2MPa multi-stage water pump and enters the RO reverse osmosis membrane element; by using the reverse osmosis characteristics of the semi-permeable membrane, water molecules are permeated to the opposite side under high pressure, and ions, bacteria and colloidal substances with large molecules are left on the high-pressure side, and clean desalted water can be obtained on the low-pressure side.​

[0017] The water that passes through the RO membrane enters a water tank and is sterilized and disinfected by adding chlorine through a chlorine adding device 9. The chlorine is added in a slightly cool state and is continuously stirred to ensure uniform dissolution. The amount of chlorine added is 15 mg / L, and the water is kept for 2 hours before being fully aerated in an aeration tank. The exhaust gas from the upper part of the aeration tank should be discharged to a high point outside the room.

[0018] The contents not described in detail in the specification belong to the prior art known to those skilled in the art. The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
