Waste water purifying device

Abstract

A kind of wastewater purification equipment, including a neutralization system, a sedimentation system and a filtration system; the neutralization system includes a neutralization tank, the upper end of the neutralization tank is connected with a water inlet pipe and a feed pipe, and the side wall of the neutralization tank is penetrated with a The first stirring shaft and the second stirring shaft, the bottom of the neutralization tank is fixedly provided with a partition, and the middle part of the partition is provided with a downhole connected with the neutralization tank; the sedimentation system includes a sedimentation tank arranged below the neutralization tank, The bottom of the sedimentation tank is also connected with a water guide pipe, and the other end of the water guide pipe is raised upwards and connected with a nozzle; the filtration system includes a water storage tank arranged under the nozzle, and the upper part of the water storage tank is provided with a filter layer and an adsorption layer up and down. The bottom is connected with a water outlet pipe. The invention provides waste water purification equipment, which has higher neutralization efficiency, can monitor the thickness of sediment in a sedimentation tank in real time, and can effectively improve the use efficiency of a filtering device.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to waste water purification equipment. Background technique [0002] In order to protect the environment and save water resources, industrial and domestic sewage and other waste water need to be treated accordingly to meet the discharge standards before they can be discharged or recycled. However, it is determined whether the waste water can be discharged or recycled. The key to water is wastewater treatment technology. Wastewater treatment is the use of physical, chemical and biological methods to treat wastewater, purify wastewater, reduce pollution, and achieve wastewater recovery and reuse, making full use of water resources. Common wastewater and waste liquid usually contain various organic substances, and the composition is relatively complex. [0003] Existing wastewater purification equipment is mainly divided into two types: industrial and civil. Civilian...

Problems solved by technology

Among them, neutralization is to adjust the acidity and alkalinity of wastewater, because most industrial wastewater is not neutral, and it needs to be neutralized before other treatments can be carried out smoothly. Most of the existing neutralization methods are based on the acidity and alkalinity of wastewater Add neutralizing agents to the neutralizing wastewater, and then stir the wastewater to make it fully. Most of the existing stirring methods are to add one or more vertical stirring paddles in the neutralization tank. Although the installation is convenient, the stirring range is limited and cannot Fully stir the wastewater in the whole pool

The existing filtration process is also similar, usually waste water is passed through the middle of the filter screen in the form of water flow, which will lead to a relatively low utilization rate of the filter screen, and the edge of the filter screen is often not effectively utilized.
