Waste water treatment device

Abstract

A waste water treatment device comprises a treatment box, a buffer box, a controller and a stirrer. One side of the treatment box is connected with a water inlet pipe, and the other side of the treatment box is connected with the buffer box. A PH meter a is arranged in the treatment box and connected with the controller through an acid-base signal line a. An acid-base liquid box and the stirrer are arranged on the treatment box. The bottom of the acid-base liquid box is connected with the treatment box through a liquid drainage pipe. A liquid drainage valve is arranged on the liquid drainage pipe and connected with the controller through a liquid drainage control line. The waste water treatment device is simple in structure, the buffer box is arranged on the downstream part of the treatment box, primarily-treated waste water can express the after-treatment pH value, waste water is neutralized more effectively and precisely, the treatment effect is good, the work efficiency is high, and the waste water treatment device is easy to popularize.

Description

technical field [0001] The invention relates to a waste water treatment device. Background technique [0002] At present, there are a large number of chemical laboratories in the society, which are distributed in governments, enterprises, universities, and various research and development testing institutions. According to statistics, at the end of 2014, there were more than 6,000 testing laboratories accredited by CNAS. Labs are even more so. The characteristic of these laboratory wastewater is that the amount of acid-base wastewater produced by a single laboratory is small every day, and the amount is not fixed, so it is not convenient for centralized treatment. Although some laboratories are discharged after simple manual dilution and neutralization, it requires regular work. It is time-consuming and labor-intensive to monitor the pH value of wastewater from time to time, and to carry out acid-base neutralization treatment according to the pH value, and it is difficult t...

Problems solved by technology

The characteristic of these laboratory wastewater is that the amount of acid-base wastewater produced by a single laboratory is small every day, and the amount is not fixed, so it is not convenient for centralized treatment. Although some laboratories are discharged after simple manual dilution and neutralization, it requires regular work. It is time-consuming and labor-intensive to monitor the pH value of wastewater from time to time, and to carry out acid-base neutralization treatment according to the pH value, and it is difficult to ensure that the pH value of each discharged wastewater meets the requirements; most of the wastewater is directly discharged into the city without strict treatment Domestic sewage pipe network or rivers and lakes, which not only increases the workload of the city's sewage treatment system, but also seriously threatens ecological security

[0003] The traditional acid-base water treatment device can only neutralize the acid-base water once, and cannot completely balance its pH. Often the pH of the drainage cannot meet the discharge standards and modern discharge requirements. Therefore, an improved technology is urgently needed to solve the above problems. technical flaw
