Abstract

Provided is a latex paint waste water pre-treating device. A water inlet tank, a flocculation reaction tank and a water outlet tank are sequentially arranged on a support, the water inlet tank is communicated with the flocculation reaction tank, the flocculation reaction tank is communicated with the water outlet tank, the water inlet tank, the flocculation reaction tank and the water outlet tank are connected to form a whole, a water inlet pipe is arranged on one side of the water inlet tank, a preliminary precipitation tank is arranged at the bottom, a first blow-off pipe is arranged at the lower end of the preliminary precipitation tank, a second blow-off pipe and a third blow-off pipe are arranged at the bottom of the flocculation reaction tank, an electric flocculation reactor is arranged in the flocculation reaction tank, a water outlet pipe is arranged on one side of the water outlet tank, a secondary precipitation tank is arranged at the bottom, a fourth blow-off pipe is arranged at the lower end of the secondary precipitation tank, and the water inlet tank, the flocculation reaction tank and the water outlet tank are insulator. The problem of latex paint wastewater treatment is solved, latex paint wastewater can be demulsified and flocculated without agents, the suspended matter and pollutant disposal efficiency is high, and the biodegradability of the latex paint wastewater is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment equipment or devices, and in particular relates to a latex paint wastewater pretreatment device. Background technique [0002] In recent years, the real estate construction industry has become a major pillar industry that stimulates the national economy, and the consumption of latex paint has also increased year by year. Therefore, latex companies of various sizes are blooming all over the country. Due to the backwardness of the production process and the weak awareness of environmental protection, the treatment of latex paint production wastewater has not been paid attention to by the application. With the introduction of my country's "Water Ten Measures", the requirements for environmental protection are getting higher and higher, and the problem of sewage treatment and discharge has become a top priority. [0003] Latex paint wastewater is mainly produced when washing production equip...
