Embodiment 1

[0036] This embodiment provides a treatment device for desulfurization wastewater, see Figure 1-4, comprising a base 27 and a housing 14; the housing 14 is located above the base 27, and the inside of the housing 14 is provided with a neutralization water tank, a neutralization sedimentation tank 8, a storage tank 17, a storage water tank 24, a first support plate 18 and The second support plate 10; the bottom of the housing 14 is equipped with a storage water tank 24, and the inside of the storage water tank 24 is equipped with a water quality detector 26. The water quality detector 26 can effectively detect the water quality inside the storage water tank 24, and the storage water tank 24 The top is equipped with a filter funnel 23; the top of the filter funnel 23 is provided with a second support plate 10, the neutralization sedimentation box 8 and the filter chamber 20 are all placed on the second support plate, and the filter chamber 20 communicates with the filter funnel ...

Embodiment 2

[0055] This embodiment provides a treatment method for desulfurization wastewater, using the treatment device for desulfurization wastewater in Example 1, the treatment method for desulfurization wastewater includes the following steps:

[0056] Step S1, moving the desulfurization wastewater treatment device to a position where operation is required;

[0057] Step S2, inject part of the materials for neutralizing the waste water into the neutralization chamber, then inject the waste water into the neutralization chamber, then inject part of the materials for neutralizing the waste water into the neutralization chamber, and let it stand for 5-10 minutes. After the water is no longer turbid, put the neutralized Wastewater flows into the neutralization settling tank;

[0058] Step S3, the pH sensor automatically detects the pH value of the wastewater in the neutralization settling tank, and when it reaches neutral or slightly alkaline, the wastewater is introduced into the filter...

Abstract

The invention discloses a treatment device and method of desulfurization wastewater, and belongs to the technical field of desulfurization wastewater treatment.The problems of large investment, low water production rate and high operation cost of an existing treatment process are solved. The treatment device comprises a base and a shell; the shell is internally provided with a neutralization watertank, a neutralization precipitation tank, a storage pot, a storage water tank, a filter funnel, a first supporting plate and a second supporting plate; the storage water tank is internally providedwith a water quality detector, and the filter funnel is installed at the top of the storage water tank; and the second supporting plate is arranged at the upper part of the filter funnel, and the neutralization precipitation tank and a filter chamber are both placed on the second supporting plate. The treatment method comprises the steps that a part of materials is injected into a neutralization chamber, then the wastewater is injected into the neutralization chamber, then a part of the materials is injected into the neutralization chamber, and the neutralized wastewater flows into the neutralization precipitation tank; the wastewater is introduced into the filtration chamber and then enters the storage water tank after filtration; and after the water quality reaches a standard, the desulfurization wastewater treatment is completed. The treatment device and method of the desulfurization wastewater can be used for the treatment of the desulfurization wastewater.

Description

technical field [0001] The invention relates to the technical field of desulfurization wastewater treatment, in particular to a treatment device and method for desulfurization wastewater. Background technique [0002] my country is a country rich in coal resources, and thermal power currently accounts for more than 70% of the entire power generation industry. In recent decades, although the country has adopted environmental protection policies such as index restrictions and sewage charges, the total amount of desulfurization wastewater discharged every year is still huge. The area of ​​wastewater pollution is rapidly expanding, causing huge damage to crops, forests and human health in my country, and has also become an important factor restricting the sustainable development of my country's economy and society. With the increasingly stringent national environmental protection requirements, desulfurization wastewater has attracted great attention because of its high concentr...
