Harmless treatment system and method for chemical wastewater

Abstract

The invention relates to the technical field of chemical wastewater, in particular to a harmless treatment system and method for chemical wastewater. The harmless treatment system for the chemical wastewater comprises a bottom rack, a supporting frame, a filtering mechanism, a communicating pipe and a secondary treatment mechanism. According to the invention, a rotating rocker is matched with a fixed pulley through a traction rope to drive a collecting plate, so that filtered sundries can be upwards pulled and lifted, and a worker does not need to enter the device to clean the sundries. In a stimulation treatment mechanism, rotating blades are used for cleaning the chemical wastewater again through the mutual cooperation of a cleaning net and a disinfectant. In cleaning branch chains, a cleaning rack drives a brush to clean sundries on a filter screen through mutual cooperation of a tensioning spring rod and a cleaning plate, and the situation that the sundries block the filter screen and affect the filtering efficiency of the chemical wastewater is avoided.

Description

technical field [0001] The invention relates to the technical field of chemical wastewater, in particular to a harmless chemical wastewater treatment system and treatment method. Background technique [0002] Chemical wastewater is pure water that changes its original physical or chemical properties after use, and becomes wastewater containing different types of impurities. Chemical wastewater includes process wastewater, cooling water, waste gas washing water, equipment and sites discharged from chemical production. Wastewater such as flushing water, if discharged without treatment, will cause different properties and degrees of pollution of water bodies, thereby endangering human health and affecting industrial and agricultural production. [0003] At present, there are the following problems in the process of chemical wastewater treatment: a. Due to the presence of impurities with large diameters in the traditional chemical wastewater, it is necessary to filter the chemic...

[0002] Chemical wastewater is pure water that changes its original physical or chemical properties after use, and becomes wastewater containing different types of impurities. Chemical wastewater includes process wastewater, cooling water, waste gas washing water, equipment and sites discharged from chemical production. Wastewater such as flushing water, if discharged without treatment, will cause different properties and degrees of pollution to the water body, thereby endangering human health and affecting industrial and agricultural production

[0003] At present, there are the following problems in the process of chemical wastewater treatment: a. Due to the presence of impurities with large diameters in the traditional chemical wastewater, it is necessary to filter the chemical wastewater during the treatment process, and the filtered impurities It is usually necessary to manually enter the equipment to take it out. The gas composition inside the equipment is unstable and the risk factor of the worker's operation is high, which may easily cause casualties; b. Due to the different diameters of the debris inside the chemical wastewater, the traditional chemical wastewater filtration process is only performed once. Filtration treatment, there are still impurities in the chemical wastewater, which will affect the subsequent disinfection treatment of chemical wastewater. At the same time, the impurities in the chemical wastewater may block the inside of the filter equipment, affecting the filtration efficiency of chemical wastewater
