Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an environmentally friendly wastewater filtration and purification device. Background Technology

[0002] With the continuous improvement of people's living standards, the discharge of domestic sewage is becoming increasingly serious. Domestic sewage is wastewater discharged from residents' daily lives, mainly originating from residential and public buildings, such as houses, government offices, schools, hospitals, shops, and public places. The pollutants contained in domestic sewage are mainly organic matter (such as proteins, carbohydrates, fats, urea, ammonia nitrogen, etc.) and a large number of pathogenic microorganisms. The organic matter present in domestic sewage is extremely unstable and easily decomposes, producing a foul odor. Bacteria and pathogens use the organic matter in domestic sewage as nutrients to multiply rapidly, which can lead to the spread and epidemic of infectious diseases. Therefore, domestic sewage must be treated before discharge.

[0003] As impurities accumulate on the filter screen, its filtration capacity will gradually decrease, greatly affecting its filtration efficiency and causing clogging of the filtration equipment. Utility Model Content

[0004] The purpose of this invention is to provide an environmentally friendly wastewater filtration and purification device to address the aforementioned shortcomings in the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly wastewater filtration and purification treatment device, comprising: a filter barrel, wherein a Z-shaped partition is fixedly connected to the middle of the filter barrel, the Z-shaped partition divides the inner cavity of the filter barrel into a first liquid passage and a second liquid passage, a first filter screen is inclinedly arranged in the first liquid passage, a second filter screen is inclinedly arranged in the second liquid passage, and an observation window is provided on the side of the filter barrel for observing the situation inside the second liquid passage.

[0006] Furthermore, each of the Z-shaped partition and the inner wall of the filter barrel is fixedly connected to an installation block, and the two sides of the first filter screen are mounted on the two installation blocks.

[0007] Furthermore, a U-shaped protruding ridge is fixedly connected to the inner wall of the filter barrel, and a sliding groove is provided on the U-shaped protruding ridge, and the second filter screen is slidably disposed in the sliding groove.

[0008] Furthermore, a ring frame is fixedly connected to one side of the filter barrel, and an inspection port is provided within the inner range of the ring frame on the filter barrel.

[0026] Specifically, this utility model divides the filter tank 1 into a first liquid passage channel and a second liquid passage channel by setting a Z-shaped partition 3, and respectively sets a first filter screen 4 and a second filter screen 6 in the two channels. As sewage passes through the first filter screen 4, the first filter screen 4 is gradually blocked by impurities, which reduces the water passage capacity. Sewage that cannot be processed by the first filter screen 4 enters the second liquid passage channel and is filtered by the second filter screen 6, thereby improving the filtration capacity of the filtration equipment. At the same time, the amount of sewage accumulated in the second liquid passage channel can be observed through the observation window 5 to determine whether the first filter screen 4 and the second filter screen 6 need to be cleaned or replaced, further ensuring that the sewage treatment efficiency is guaranteed.

[0027] Furthermore, a mounting block 31 is fixedly connected to the Z-shaped partition 3 and the inner wall of the filter barrel 1, and the two sides of the first filter screen 4 are mounted on the two mounting blocks 31.
