Wastewater treatment device

Abstract

The invention discloses a wastewater treatment device. The wastewater treatment device comprises a main body, wherein a first guide pipe is arranged at the right side of the main body and penetrates through the main body; a second guide pipe is arranged at the left side of the top end of the main body and penetrates through the main body; a first blocking plate is arranged at the left side of theinner wall of the main body. The wastewater treatment device has the advantages that by matching the second guide pipe and the main body, and matching the first blocking plate and a third guide pipe,the second guide pipe is connected with a wastewater intake pipe, the wastewater enters into the part between the main body and the first blocking plate, the larger impurity particles are settled to the bottom part of the main body due to overlarge self gravity, and the wastewater carrying the smaller impurity particles enters into the middle part of the main body via the third guide pipe; by matching a motor and a rotary rod, and matching a sleeve cylinder and a through hole, the sleeve cylinder is driven by a motor to increase the filtering speed of the wastewater at a filter net in the rotation process; the wastewater treatment efficiency is improved, the practicality is strong, and the convenience in use is realized.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment devices, in particular to a wastewater treatment device. Background technique [0002] Wastewater refers to domestic sewage, industrial wastewater, etc. that contain pollutants such as oxygen-consuming pollutants, plant nutrients, and toxic pollutants. Wastewater has considerable damage to the environment. Untreated wastewater directly flows into channels, rivers, and lakes to pollute Surface water, if it is highly toxic, will lead to the death of aquatic animals and plants and move them to extinction. Industrial wastewater may also seep into groundwater and pollute groundwater. If the surrounding residents use polluted surface water or groundwater as domestic water, it will endanger their health and cause death in severe cases. , industrial wastewater infiltrates into the soil, causing soil pollution, affecting the growth of plants and microorganisms in the soil. Some industrial wast...

[0002] Wastewater refers to domestic sewage, industrial wastewater, etc. that contain pollutants such as oxygen-consuming pollutants, plant nutrients, and toxic pollutants. Wastewater has considerable damage to the environment. Untreated wastewater directly flows into channels, rivers, and lakes to pollute Surface water, if it is highly toxic, will lead to the death of aquatic animals and plants and move them to extinction. Industrial wastewater may also seep into groundwater and pollute groundwater. If the surrounding residents use polluted surface water or groundwater as domestic water, it will endanger their health and cause death in severe cases. , industrial wastewater infiltrates into the soil, causing soil pollution, affecting the growth of plants and microorganisms in the soil. Some industrial wastewater also has an unpleasant stench, which pollutes the air. Toxic and harmful substances in industrial wastewater will be ingested and absorbed by plants and remain in the body. Then it reaches the human body through the food chain, causing harm to the human body. For example, the patent application number 201621257617.2 includes a filter mechanism and an incineration mechanism. The time required is too long, resulting in low efficiency of sewage treatment, and the time is too long
