Problems solved by technology
[0002] There are a large number of small and medium-sized stainless steel casting (precision casting) enterprises in Fujian Province, and these enterprises generally have a small daily discharge of production wastewater, uneven discharge, and limited sites for the construction of sewage treatment station civil structures in the factory area ( Large-scale excavation may affect the structural safety of nearby buildings), the location of the factory area without government investment in industrial or municipal sewage treatment plants can allow the pretreated wastewater discharged by these enterprises to connect to the sewage plant pipe network, etc.

Embodiment Construction
[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0035] On the basis of considering the investment cost, the present invention is mainly used for the surface treatment of waste water of stainless steel workpieces whose waste water treatment capacity (Q) is less than or equal to 100m3 / d.
[0036] The invention scheme and design principles of this application conscientiously implement the national economic construction policy, and its technical standards follow the existing indicators and specifications:
[0037] 1.1 "Water Law of the People's Republic of China";
[0038] 1.2 "Environmental Protection Law of the People's Republic of China" and "Water Pollution Prevention and Control Law";
[0039] 1.3 "Urban Sewage Recycling - Classification" (GB18919-2002);
[0040] 1.4 "Urban Sewage Recycling - Industrial Water Quality" (GB19923-2005);
[0041] 1.5 "Integrated Wastewater Discharge Standard" (GB8978-1996)...

The invention discloses a treatment process for industrial production wastewater treatment. The key points of the technical scheme include an oil and slag separation well, a comprehensive adjustment tank, a flocculation sedimentation tank, a van filter press, a waste water treatment host, and a reuse water tank. , the wastewater treatment host includes a fluidized anaerobic tank, a biological contact oxidation tank, a molecular sieve deep-bed filter and a biomass deep-bed filter for the wastewater treatment process; the complete set of wastewater treatment equipment of the present invention integrates a variety of component equipment into one In the equipment, the production waste water output by the target stainless steel production process is treated step by step. The treatment process includes the use of "mechanical press filter mud water separation technology and molecular sieve deep bed filter and biomass deep bed filter technology", and the final treatment output Those that meet the standards can be reused for production. The waste water treatment equipment of the present application is easy to operate and has high work efficiency. The complete set of equipment adopting the scheme greatly reduces the setting cost and operating cost.
Description
technical field [0001] The invention relates to the field of waste water treatment, more specifically it relates to a treatment process for industrial production waste water treatment. Background technique [0002] There are a large number of small and medium-sized stainless steel casting (precision casting) enterprises in Fujian Province, and these enterprises generally have a small daily discharge of production wastewater, uneven discharge, and limited sites for the construction of sewage treatment station civil structures in the factory area ( Large-scale excavation may affect the structural safety of nearby buildings), the location of the factory area without government investment in industrial or municipal sewage treatment plants can allow the pretreated wastewater discharged by these enterprises to be connected to the sewage plant pipe network, etc. Therefore, in order to solve the wastewater treatment problems of these enterprises, our company has researched and devel...
