Automatic sewage treatment device and method applied to circuit board production industry

Abstract

The invention discloses an automatic sewage treatment device and method applied to the circuit board production industry. The automatic sewage treatment device comprises a sewage flocculation pool, asewage sedimentation pool and a flocculation liquid preparation tank, and further comprises a flocculation liquid stirring device located in a tank body of the flocculation liquid preparation tank, and a flocculant feeding device located outside the tank body of the flocculation liquid preparation tank; a sewage partition plate is arranged in a pool body of the sewage sedimentation pool; and sewage stirring and heating devices and flocculation liquid spraying devices are arranged in a pool body of the sewage flocculation pool. According to the automatic sewage treatment device applied to the circuit board production industry, sewage in a sewage treatment pool is heated to the appropriate temperature, thus flocculant powder is dissolved in the sewage better, and the chance of direct contactbetween an operator and the flocculant powder and the sewage is reduced.

Description

technical field [0001] The invention relates to the technical field of automatic sewage treatment of circuit boards, in particular to an automatic sewage treatment equipment and treatment method applied in the circuit board production industry. Background technique [0002] There are many pollutants in the production process of circuit boards, and the discharged wastewater mainly contains copper, chromium, nickel, zinc, acid and alkali and other polluting components. If the above wastewater is not effectively treated, it will cause serious pollution to the environment. When natural water bodies are polluted by acid, alkali, and heavy metals, the buffering effect of the water body is destroyed, which deteriorates the water quality, inhibits or prevents microbial activities, reduces the self-purification ability of water, and also causes harm to crops. Heavy metal ions have a great impact on human health. Harmful, and heavy metal ions in water will not be degraded by microorg...

Problems solved by technology

[0004] In the design and development process of the above-mentioned automatic sewage treatment equipment used in the circuit board production industry, the following technical problems need to be solved: in the process of flocculation treatment of sewage, according to the actual situation, the sewage in the sewage treatment tank needs to be heated to Appropriate temperature, so that the sewage can get better flocculation effect; the traditional method is to put the flocculant powder directly into the sewage treatment tank, so that the flocculant powder will be difficult to dissolve into the sewage, thereby reducing the flocculation of sewage Effect; Usually, the operator directly pours the flocculant powder into the sewage treatment tank, and the dust raised by the flocculant powder and the gas generated by the sewage will enter the human respiratory tract, seriously affecting human health
