Comprehensive sewage treatment device

Abstract

The invention provides a comprehensive sewage treatment device and belongs to the field of environment protection and purification. The comprehensive sewage treatment device comprises a moving deviceand a sewage treatment device body and is characterized in that a cover plate is hinged to the upper surface of a filter tank, and a coarse filter screen is arranged in the inner cavity of a feeding hopper; a lifting rack is arranged at the bottom of the inner cavity of an activated carbon filter dish; a pH measuring agent is arranged at the bottom of the left side of an acid-base neutralizing tank; an acid agent is arranged on the upper side of the inner cavity of the acid-base neutralizing tank, and an alkaline agent is arranged on the lower side of the acid agent; a sterilizing cavity is arranged on the right side of the inner cavity of a water storage tank; a water purification cavity is arranged on the left side of the water storage tank. The comprehensive sewage treatment device hasthe advantages that the activated carbon filter dish is arranged in the inner cavity of the filter tank through support blocks and has a function of filtering and collecting impurities; the acid agentand the alkaline agent are connected with a chemical adding device through connecting pipes to perform acid-base neutralization on sewage; the device is simple in structure, high in practicality andgood in sewage treatment effect.

[0002] With the rapid development of science and technology, there are more and more teaching and testing laboratories based on chemistry and biology; such laboratories are usually located in colleges and universities, research institutes, government environmental and health monitoring The sewage purification of institutions, enterprise laboratory testing departments and testing intermediary agencies is a process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse, and it is also increasingly entering the daily life of ordinary people. Purification with wastewater is more important, not only for the protection of land resources, but also for the safety of crops; the current household water is basically discharged directly, no longer retained, and can only flow away along the drainage holes, and directly The discharged sewage will also have a certain impact on the environment. Faced with the increasingly scarce water resources, the water that flows away every day has become a luxury waste; the comprehensive treatment of domestic wastewater is currently low, and most domestic sewage is only collected and treated. Staying in the preliminary filtration stage will cause a certain degree of impact on the urban sewage treatment plant, and then have an adverse impact on the environment and ecosystem; for this reason, we propose a comprehensive sewage treatment device
