Electromagnetic type muddy water separating tower and electromagnetic type muddy water separating method

Abstract

The invention provides an electromagnetic type muddy water separating tower and an electromagnetic type muddy water separating method. By means of the electromagnetic type muddy water separating tower and the electromagnetic type muddy water separating method, the muddy water separating processing effect can be improved, and the construction investment, the construction occupied space and the operating processing cost can be reduced. The electromagnetic type muddy water separating tower comprises a tower body which comprises an upper straight barrel body and a lower conical body, an electromagnetic material plate is arranged on the inner wall of the conical body, and a high-voltage static generating device outside the tower body is electrically connected with the electromagnetic material plate. According to the electromagnetic type muddy water separating method, the muddy water is delivered into a steam-water separating barrel in the tower body so that the steam-water separation can be carried out on the muddy water, and the rising water flow can be formed by the muddy water at an outlet in the bottom of the steam-water separating barrel. A suspension flocbed is formed under the electromagnetism attraction through the mixture containing coagulant and fine particles in the rising flow due to the fact that the rising flow contains electrical property substances, the suspension flocbed blocks and adsorbs more small particles, and the small particles are coagulated into large particles to be deposited into the conical body under the double action of the gravity and the electromagnetism attraction. A mud layer in the conical body becomes concentration mud to be discharged under the double action of water gravity compression and a compression double electrode layer produced by electrode discharging.

Description

technical field [0001] The present invention relates to a high-turbidity muddy sewage treatment technology, especially for the large-flow filter backwash water and sedimentation tank tail water generated in the production process of municipal waterworks (these two kinds of waste water are collectively referred to as A high-efficiency, energy-saving and environment-friendly mud-water separation method and its device for simultaneously performing mud-water concentration and solid-liquid separation and realizing water resource recovery and purification treatment. Background technique [0002] With the development of urbanization and industrialization in our country, the annual urban tap water supply increases year by year, and the muddy water generated in the production of tap water grows geometrically. At the same time, various discharged muddy water directly enters the municipal pipe network and rivers and lakes. Cause water pollution, river, pipe network blockage, and then p...

Problems solved by technology

This supernatant is not only difficult to meet the water reuse requirements at all levels, but also does not meet the discharge standards (SS≤20mg / L)

In the tap water industry, it is difficult to further reduce the SS of the effluent by using ordinary sedimentation tanks to treat the muddy water, and the cost of in-depth fine filtration treatment is high
