Embodiment 1

[0030] Such as Figure 1-8 As shown, a system for purifying wastewater includes a filter device 2, a waste removal device 4 for decomposing toxic substances in wastewater, a water inlet pipe 1, and a connecting pipe 3 for connecting the filter device 2 and the waste removal device 4, The water inlet pipe 1 communicates with the filter device 2. The filter device 2 includes a hollow water storage tank 21 with an open end and a filter tower arranged in the water storage tank 21. The filter tower is provided with a first water inlet toward the bottom of the water storage tank 21. The water inlet pipe 1 is sealed and connected to the first water inlet. Correspondingly, the bottom of the water storage tank is provided with a through hole for the water inlet pipe 1 to pass through, and the through hole matches the diameter of the water inlet pipe 1 . In the embodiment, waste water containing a large amount of solid particles and organic matter first enters the filter tower from the ...

Embodiment 2

[0038] Such as Figure 8As shown, on the basis of Embodiment 1, this embodiment also includes a neutralization device for adjusting the pH value of wastewater; the neutralization device includes a neutralization tank 51 connected with the waste removal device 4, for the acidic neutralizer to pass through Into the first through pipe 52 of the neutralization tank 51 and the second through pipe 53 for the alkaline neutralizer to pass into the neutralization tank 51; the neutralization tank 51 is provided with a drain pipe 55 for clean water discharge. Because the actual wastewater often contains a large amount of acid and alkali substances, the neutralization device can neutralize the acid or alkali in the wastewater, so that the purified water can be used directly.

[0039] Such as Figure 8 As shown, the neutralization device also includes a mixing device for making the acid and alkali neutralizer mix more uniformly with the waste water; the mixing device includes a spherical ...

Abstract

The invention discloses a system used for purifying wastewater, and relates to environment-friendly equipment. The system comprises a filter device, a waste removal device used for decomposing poisonous substances in wastewater, a water inlet tube and a connecting tube for enabling the filter device to communicate with the waste removal device, wherein the water inlet tube communicates with the filter device; the filter device comprises a hollow water storage tank with an opening in one end, and a filter tower arranged in the water storage tank; one end, towards the bottom of the water storagetank, of the filter tower is equipped with a first water inlet; the water inlet tube is in sealing connection with and communicates with the first water inlet; correspondingly, the bottom of the water storage tank is equipped with a through hole for allowing the water inlet tube to pass through; the through hole is adaptive to the pipe diameter of the water inlet tube. The system has the advantages of being low in cost, low in energy consumption and low in time consumption.

Description

technical field [0001] The invention relates to an environmental protection device, in particular to a system for purifying waste water. Background technique [0002] At present, domestic iron and steel, dyeing, electroplating and other industries discharge nearly ten million tons of wastewater every year. This kind of wastewater often contains a large amount of solid particles and organic substances. If it is discharged directly, it will cause serious environmental pollution. For this reason, the country usually requires wastewater discharge manufacturers to carry out previous treatment of wastewater so that it can meet certain water quality standards before it can be discharged. [0003] At present, the commonly used wastewater treatment methods mainly include neutralization method, roasting method, dialysis separation method and combined biological treatment method. However, when the above method is used to purify wastewater, there are the following problems: 1. The trea...
