technical field

The utility model belongs to the technical field of wastewater treatment, in particular to a device for treating solid particles in organic wastewater.

Background technique

With the rapid development of life and industry, the types and quantities of wastewater have increased rapidly, and the pollution of water bodies has become increasingly widespread and serious, threatening human health and safety. Since the composition of organic wastewater is more complex, and some are toxic, there will often be a large amount of solid impurities during collection and treatment. It has caused great difficulties for the subsequent treatment of organic wastewater. Organic wastewater mainly includes domestic sewage and wastewater produced in industrial production such as food processing, papermaking, and pharmaceuticals. Organic wastewater contains granular organic substances such as carbohydrates, proteins, oils, and lignin. These particulate substances exist in the sewage in a suspended or dissolved state, and can be decomposed by the biochemical action of microorganisms. During the decomposition process, oxygen needs to be consumed, so they are called oxygen-consuming pollutants. This pollutant can reduce dissolved oxygen in water, affect the growth of fish and other aquatic organisms, and deteriorate water quality.

(1) When the utility model is working, feed organic waste water into the settling tank and then add flocculant from the feeding hopper. The flocculant can remove most of the large particles of solid impurities, and the stirring device can speed up the flocculation. The settling bucket is collected and discharged, and the wastewater in the settling tank enters the filter tank through the outlet after settling for filtration. The utility model utilizes one-time flocculation and one-time filtration, which can efficiently and maximize the removal of solid particle impurities in the wastewater;

(2) The filter tank of the utility model is provided with 3 inclined filter screens with a slope, and the solid particle impurities in the organic wastewater can be filtered by each filter screen and then slide to the bottom of the filter screen slope, and after the filtration is completed, open the filter screen at the bottom of the slope. The manhole is very convenient to clean the filter residue at the bottom of the slope. At the same time, the mesh number of the filter screen decreases sequentially from top to bottom, which can filter solid particles of different particle sizes in the wastewater in layers, and the filtering effect is good.
