Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically referring to a wastewater neutralization treatment device, and relates to a wastewater neutralization treatment device. Background Technology

[0002] The production process of vitamin B12 generates a large amount of acidic and alkaline wastewater. When this wastewater enters the treatment center, it increases the amount of acid and alkali used. Therefore, the wastewater is mixed before entering the treatment center.

[0003] In existing technologies, wastewater mixing simply involves discharging both types of wastewater into the same neutralization tank to reduce acidity and alkalinity. However, due to differences in discharge volume, the effectiveness of neutralization in reducing acidity and alkalinity often fluctuates, leading to frequent changes in the amount of acid and alkali used in the treatment center, making it difficult to control. Utility Model Content

[0004] In view of this, the present invention provides a wastewater treatment device.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A wastewater neutralization treatment device includes an acid tank, an alkali tank, a neutralization tank, and a clean water tank;

[0007] The acid tank and the alkali tank are connected to the neutralization tank via acid pipes and alkali pipes, respectively.

[0008] The neutralization tank is also equipped with a spray pipe and an overflow pipe;

[0009] Both the acid tank and the alkali tank are equipped with a secondary pipe. One end of the secondary pipe is connected to the corresponding tank, and the other end is divided into two paths that are connected to the spray pipe and the overflow pipe, respectively.

[0010] Each of the secondary pipes is equipped with a solenoid valve; the neutralization tank is equipped with a pH meter; the host computer is connected to the pH meter and the solenoid valves on the two secondary pipes.

[0011] The water inlet pipe of the clear water tank is connected to the top of the side wall of the neutralization tank to collect its supernatant.

[0012] The alkali tank is also equipped with two partitions, which divide the neutralization tank into three chambers: left, middle, and right. The partitions are evenly distributed with 50mm sieve holes. The acid tube and alkali tube both lead into the right chamber.

[0013] Furthermore, both the overflow pipe and the spray pipe span three chambers.

[0014] Furthermore, the neutralization tank is provided with an exhaust port at the top.

[0015] The beneficial effects of adopting the above technical solution in this utility model are as follows:

[0016] By installing spray pipes and overflow pipes, the neutralization reaction can occur as quickly as possible, stabilizing the pH value in the neutralization tank and allowing the chemical impurities produced by the reaction to remain in the neutralization tank for easy cleaning. The installation of baffles with sieve holes allows the acid and alkali solutions coming directly from the acid and alkali tank to be mixed more evenly. Attached Figure Description

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0020] Reference Figure 1 This embodiment includes an acid tank, an alkali tank, a neutralization tank, and a clean water tank;

[0021] The acid tank and the alkali tank are connected to the neutralization tank via acid pipes and alkali pipes, respectively.

[0022] The neutralization tank is also equipped with a spray pipe and an overflow pipe;

[0023] Both the acid tank and the alkali tank are equipped with auxiliary pipes, one end of which connects to the corresponding tank, and the other end splits into two paths that connect to a spray pipe and an overflow pipe, respectively; that is... Figure 1 The aT port is divided into two paths, which are connected to two Ta ports respectively.

[0024] Each of the secondary pipes is equipped with a solenoid valve; the neutralization tank is equipped with a pH meter; the host computer is connected to the pH meter and the solenoid valves on both secondary pipes. The host computer calculates the volume of neutralized wastewater and its pH value after neutralization within one cycle based on the wastewater generated during vitamin B12 production; this pH value is used as the standard for the normal pH value in the neutralization tank. When the pH value measured by the pH meter changes significantly, the corresponding solenoid valve is activated to adjust the pH value, maintaining a stable pH value in the clear water tank.

[0025] The water inlet pipe of the clear water tank is connected to the top of the side wall of the neutralization tank to collect its supernatant.

[0026] The alkali tank is also equipped with two partitions, which divide the neutralization tank into three chambers: left, middle, and right. The partitions are evenly distributed with 50mm sieve holes. The acid tube and alkali tube both lead into the right chamber.
