Embodiment Construction

[0015] The present invention will be described in detail below in combination with specific embodiments.

[0016] The present invention as Figure 1 to Figure 4 As shown, the Venturi flowmeter 33 is respectively connected to the raw water inlet 4, the ozone self-oxidizing pipe 5 and the ozone riser 6, and the water to be treated enters the Venturi flowmeter 33 from the raw water inlet 4 and mixes with the ozone that enters from the ozone riser 6. Finally, enter the ozone self-oxidation pipe 5, enter the modified activated carbon reactor 9 after pre-ozonation is completed, utilize the pressure difference of the Venturi flowmeter 33 to suck the ozone into the raw water, and use the sudden expansion and contraction part in the ozone self-oxidation pipe 5 The generated water vortex makes the water quickly combine with the ozone, so that the pre-ozonation can be completed easily and quickly. The modified activated carbon reactor 9 is a hollow cylinder inside, and the air hole 22 o...

Abstract

The invention discloses a novel treatment device of PPCPs (pharmaceutical and personal care products). After to-be-treated water enters a Venturi meter from a raw water inlet to be mixed with ozone entering from an ozone riser, the to-be-treated water enters an ozone auto-oxidation pipe and enters a modified activated carbon reactor after being subjected to pre-ozonization, water in the modified activated carbon reactor is treated and then enters a chemical reactor, ozone and water are mixed in the chemical reactor, and the mixture is drained from a purified water outlet after being subjectedto full contact oxidation under the action of an aeration disc; a transferring cavity comprises a metal hopper and a metal retention plate, a vacuum pump is arranged on the left side of the transferring cavity, concentrated sulfuric acid and water are added from a sulfuric acid inlet and a water injection port in the chemical reactor for secondary regeneration of activated carbon, the activated carbon modified by sulfuric acid is raised to a solid-liquid separation device for secondary utilization through a material riser through a solid-liquid two phase mixing pump, and the modified activatedcarbon enters a modified activated carbon reactor through the solid-liquid separation device. The novel treatment device of PPCPs has the benefits that the device has higher removal rate for PPCPs.

Description

technical field [0001] The invention belongs to the technical field of pharmacy and relates to a PPCPs processing device. Background technique [0002] The full name of PPCPs is Pharmaceutical and Personal Care Products, which is an emerging pollutant, including various antibiotics, synthetic musk, painkillers, antihypertensive drugs, contraceptives, hypnotics, weight loss drugs, hairspray, hair dyes and fungicides, etc. With the progress and development of science, PPCPs are gradually being paid attention to because of their pseudo-persistence and physiological toxicity. The processing cost of PPCPs is relatively high. At present, the sewage treatment plants in our country do not have special processes and equipment for this series of substances. Contents of the invention [0003] The object of the present invention is to provide a PPCPs treatment device. [0004] The technical scheme adopted in the present invention comprises a Venturi flowmeter, and the Venturi flowm...
