Problems solved by technology

[0004] At present, the existing sewage treatment technologies all have unsatisfactory treatment effects on pollutants, and often fail to meet the discharge standards; high treatment costs, complex treatment facilities, many treatment units and low efficiency; when the concentration of suspended solids is high, it cannot even be treated; improper operation There are still some problems such as secondary pollution in chemical agents

Embodiment Construction

[0019] Such as figure 1 As shown, a method of using diatomite to treat mine wastewater and recycle it includes the following steps: mine wastewater is first collected through a water absorption pool 1, and the wastewater is evenly stirred by a mixer so that the fluctuating water quality can be mixed evenly At the same time, the water volume can be adjusted so that the follow-up equipment can operate continuously and stably; then the wastewater is lifted to the diatom concentrate reactor 6 through the submersible sewage pump 13, and diatom concentrate is added to the wastewater before the submersible sewage pump 13 , during the lifting process, the wastewater and diatomite are fully contacted, adsorbed and polymerized by the vigorous stirring of the pump; in the diatomite reactor 6, suspended solids, oil pollutants, part of COD and metals in the wastewater After the ions are reacted and mixed, they are adsorbed and polymerized, and then clarified in the diatomaceous earth reac...

Abstract

The invention relates to a method for treating and recycling mine wastewater by using purified diatomite; the method comprises the following steps: firstly, the mine wastewater is collected via a water absorbing tank firstly, then the wastewater is evenly stirred by a stirrer, next the wastewater is lifted to a purified diatomite reactor by a submersible sewage pump, at the same time, purified diatomite is added to the wastewater before the submersible sewage pump, and the wastewater and the purified diatomite achieves full contact, adsorption and polymerization through intense stirring of the pump in the lifting process; and in the purified diatomite reactor, suspended matters, oil pollutants, a part of COD and metal ions in the wastewater are subjected to reaction and are evenly mixed for adsorption and polymerization, then the treated wastewater is classified and is subjected to mud water separation in the purified diatomite reactor, and water in a gutter groove is disinfected by ultraviolet rays and then reaches the water quality standard of urban miscellaneous water. The method can realize full-automatic control, has simple process flow, and realizes unmanned management. The method can reuse the resources and realize the purposes of high efficiency, energy saving and resource regeneration.

Description

technical field [0001] The invention belongs to the field of mine wastewater treatment, and in particular relates to a method and equipment for treating and recycling mine wastewater by using diatom concentrate. Background technique [0002] During the production process of the mine, a large amount of mine water is continuously infiltrated by surface water and fissure water in underground rock formations. These mine waters are polluted by the production process and become sewage. Mine sewage generally contains a large amount of suspension, if it is discharged directly, it will inevitably cause pollution to the surrounding environment. [0003] my country's coal mine water treatment technology started in the late 1970s, and most of the sewage treatment work only stays in treatment for discharge. However, reuse is an inevitable trend in the development of sewage treatment today. Combining pollution prevention and reuse can not only alleviate the contradiction between supply ...
