Description

Technical Field

[0001] The invention relates to the technical field of chemical wastewater treatment, and in particular to an automatic chemical wastewater recovery system and method. Background Art

[0002] The chemical industry produces wastewater and waste liquid in the production process. These wastes contain various chemical agents and other substances, which pose a serious pollution threat to the surrounding environment and farmland, especially the pollution of water sources. Therefore, it is necessary to use sediment recovery devices to effectively treat wastewater and waste liquid to prevent environmental pollution.

[0003] However, most of the current wastewater treatment sediment recovery devices have design deficiencies. Their filter structures are often built into the device, which makes replacement and cleaning work quite cumbersome. Over time, these filter structures tend to accumulate dust, impurities and other particulate matter, which greatly reduces the filtering effect and seriously affects the operating efficiency of the device. In addition, although the filter structure of some recovery devices can be replaced, due to design defects, the fit between these filter structures and the device body is often not tight enough, which affects the sealing performance of the device. The reduction in sealing will not only lead to a decrease in treatment effect, but will also further weaken the overall operating efficiency of the recovery device.

The lifting and sealing assembly drives the grid filter 101, the filter membrane 102 and the reverse osmosis membrane 103 thereon, and the wastewater first enters the grid space, where a grid filter 101 is usually provided to intercept and remove large solid impurities in the wastewater, such as branches, plastic bags, paper, etc., to separate large particles and suspended matter from the wastewater to prevent them from entering the subsequent treatment units to cause blockage and affect the treatment effect. The wastewater after the grid treatment enters the sedimentation space, where the wastewater flows slowly, so that the suspended matter naturally settles to the bottom under the action of gravity to form sludge. At the same time, the supernatant (relatively clear wastewater) overflows from the upper part of the sedimentation space and enters the next treatment unit. The supernatant enters the biological treatment space, such as an anaerobic reactor or an aerobic reactor.These reactors contain a large number of microorganisms, which feed on organic matter in the wastewater and decompose it into carbon dioxide and water through metabolism; anaerobic reactors operate under anaerobic conditions, and microorganisms decompose organic matter through anaerobic respiration; aerobic reactors need to be filled with oxygen, and microorganisms perform aerobic respiration under aerobic conditions; biological treatment units are the main link in removing organic matter in wastewater treatment, and wastewater after biological treatment enters the filtration space, such as sand filters and membrane filtration systems; filter membranes 102 use the size of membrane pores to intercept impurities of different sizes; these filtration devices can further purify wastewater and improve its water quality.

The flotation equipment is mainly used to separate grease and tiny particles in wastewater. By introducing tiny bubbles into the wastewater, the bubbles attach to the grease and tiny particles, causing them to float to the surface of the water to form scum. The scum is then scraped and skimmed off, thereby achieving wastewater purification. According to the nature of the wastewater and the treatment requirements, the chemical agent dosing system will add grease and tiny particles to the wastewater.
