Multi-use environment-friendly water treatment equipment

Abstract

The invention discloses multi-use environment-friendly water treatment equipment and belongs to the field of environment-friendly water treatment. The multi-use environment-friendly water treatment equipment comprises a water inlet pipe, a coarse filtering pond, a fine filtering pond, an anaerobic pond, a first anoxic pond, an aerobic pond, a second anoxic pond, a membrane pond and a water outletpipe; the coarse filtering pond, the fine filtering pond, the anaerobic pond, the first anoxic pond, the aerobic pond, the second anoxic pond, the membrane pond and the water outlet pipe are sequentially communicated with one another; the fine filtering pool is a vertical filtering pipeline; the interior of the pipeline is rotationally connected with a filter net; the upper end of the filter net is communicated with a backwashing device; a sewage pond is in a cylinder shape; the middle position in the sewage pond is provided with a rotary shaft; a helical blade is fixedly connected to the rotary shaft and is provided with multiple water leakage holes; the outer surface of the rotary shaft is provided with multiple holes; the holes are connected with a flocculant device through a pipeline in the rotary shaft; and the flocculant device is arranged in the rotary shaft. By adopting the multi-use environment-friendly water treatment equipment provided by the invention, sewage is subjected to a series of sewage treatment processes, so that comprehensive purification treatment of the sewage is realized, and the purification degree of the sewage is increased.

Description

technical field [0001] The invention relates to the field of environment-friendly water treatment, and more specifically relates to a multi-purpose environment-friendly water treatment equipment. Background technique [0002] The function of the aerobic pool is to allow the activated sludge to perform aerobic respiration, further decompose the organic matter into inorganic matter, and remove the pollutants. The function of the aerobic pool is to control the oxygen content and other requirements of the microorganisms. Only when microorganisms can perform aerobic respiration with the greatest benefit; anaerobic treatment uses the action of anaerobic bacteria to remove organic matter in wastewater, which usually takes a long time. The anaerobic process can be divided into hydrolysis stage, acidification stage and methanation stage ; [0003] The anoxic pool is relatively anaerobic and aerobic, and generally refers to a biochemical system in which the dissolved oxygen is contro...
