Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment equipment, in particular to an integrated coating wastewater treatment device. Background Art

[0002] Paint wastewater is widely found in paint production lines in the machinery, home appliances, electronics and other industries. Paint wastewater mainly comes from the cleaning of batching tanks and reactors and the preparation of paints of different colors. Paint wastewater has a high concentration of organic matter, and its chromaticity and suspended matter content are also high. In addition, it also contains a large amount of nano-scale inorganic materials, such as titanium dioxide, kaolin and various colored pigments. In the process of paint wastewater treatment, PH adjustment, coagulation and flocculation are commonly used at home and abroad to precipitate and remove suspended matter in sewage. Therefore, the effect of PH adjustment equipment, coagulation equipment and flocculation equipment directly determines the precipitation effect of suspended matter and metal substances.

[0003] The existing integrated paint wastewater treatment equipment does not have aeration and stirring functions during biodegradation. It only places the wastewater into the treatment chamber for static storage, which makes it impossible for the microorganisms to obtain sufficient oxygen supply, resulting in insufficient degradation of organic matter in the wastewater and low degradation efficiency. Therefore, an integrated paint wastewater treatment equipment is proposed.

[0004] An integrated treatment equipment for coating wastewater disclosed in the announcement number CN205616709U includes a chemical treatment tank, a biological treatment tank, an inclined tube sedimentation tank and an outlet tank. The chemical treatment tank includes a regulating storage tank, a coagulation tank, a flocculation tank and an intermediate tank. The coagulation tank pipeline is connected with a PAC pump, and the flocculation tank pipeline is connected with a PAM pump; the intermediate tank and the biological treatment tank pipeline are connected in series with a first pump and a sludge dewatering machine; the intermediate tank is provided with a liquid level switch, and the liquid level switch is used to control the opening and closing of the first pump, the PAC pump and the PAM pump; the biological treatment tank and the inclined tube sedimentation tank are separated by a first overflow plate, and the inclined tube sedimentation tank and the outlet tank are separated by a second overflow plate. The utility model has the following beneficial effects: high efficiency and energy saving, high integration, can be set up on the ground, and occupies less area; impact resistance, the corridor structure saves the lifting pump and control device, and the lifting is homogeneous and uniform; it can save liquid medicine and has a good control effect; the multi-stage overflow method saves the lifting pump between the tank bodies, saves energy and reduces emissions, and reduces equipment investment costs.

[0005] Although the above patent has achieved high efficiency and energy saving, high integration, can be set up on the ground, and occupies a small area; it is impact-resistant, and the corridor-type structure eliminates the need for lifting pumps and control devices, and the quality and quantity are improved evenly; it can save liquid medicine and has a good control effect; the multi-stage overflow method eliminates the need for lifting pumps between tanks, saves energy and reduces emissions, and reduces equipment investment costs; however, the device has a complex structure and does not have the ability to disassemble and replace the filter device to ensure the filtering effect and avoid clogging of the filter device that affects the normal use of the equipment.
