01 Treatment ideas for experimental wastewater

Customer service: Guangxi Zhuang Autonomous Region Environmental Protection Research Institute

Source of laboratory wastewater: comprehensive wastewater generated in the process of laboratory drugs, reagents, test solutions, waste liquids, residual reagents, container washing, instrument cleaning, and leakage; its components are complex: inorganic, organic, biological Waste water, waste water containing a variety of heavy metal ions, etc., the direct discharge has a great impact on the water environment;

The key point of the treatment process is to do a good job in the quality classification of the wastewater. The heavy metal ions are first adjusted by acidity to complete the chromium breaking, and then the pH value is adjusted. Most of the heavy metal ions are removed by precipitation, and the treated heavy metal wastewater and organic wastewater enter together. Oxidation treatment unit, under the action of hydrogen peroxide, part of the chelate can be decyclized and decomposed to improve biodegradability.

After AO+MBR combined biochemical process, most of the organic matter in the water is degraded, and the conductivity of the effluent water is tested. If it is more than 1000us, the NF nanofiltration system is activated to further remove the residual metal ions in the system; the actual operation of the integrated treatment equipment Effect The effluent quality is better than the third-level discharge standard of "Comprehensive Wastewater Discharge Standard of the People's Republic of China" (GB8978--1996).

02 Experimental wastewater treatment of Shenzhen Chimelong Technology Co., Ltd.

It is also a comprehensive wastewater generated in the process of experimental analysis of wastewater, laboratory drugs, reagents, test solutions, waste liquids, residual reagents, container washing, instrument cleaning, and leakage; its components are complex: inorganic, organic, biological Such waste water, waste water containing a variety of heavy metal ions, etc., the direct discharge has a great impact on the water environment.

The treatment process adopts the whole process: physicochemical pretreatment + biochemical + magnetic separation + double-membrane advanced treatment.

First, after adjusting the pH value to break the chromium precipitation, the supernatant liquid enters the aerobic tank and the organic matter is degraded under the action of activated sludge, and the mixed liquid enters the magnetic separation section. Under the action of strong magnetism, the activated sludge in the mixed liquid realizes polarity Adsorption can quickly achieve solid-liquid separation. The sludge is returned to the front-end aerobic tank under the action of the sludge return pump, and the supernatant enters the UF water inlet tank. At this time, the biochemically treated effluent still contains a small amount of heavy metal ions in ultrafiltration and RO After double filtration of reverse osmosis, complete interception and separation can be achieved. The quality of reverse osmosis product water meets the needs of production and reuse, and the concentrated water is discharged to municipal pipelines.

03 Medical Wastewater Treatment

Client: 500 tons/day integrated treatment project of Qianxinan Maternal and Child Health Children's Hospital in Guizhou

Project construction background: Under the new crown epidemic, the medical sewage project supporting the new hospital project has put forward higher actual needs for epidemic prevention and sterilization, although the project only requires the discharge water quality to meet the water pollution discharge standard for medical institutions (GB18466-2005) Comprehensive medical treatment The pretreatment standards for water pollutants in institutions and other medical institutions are sufficient. The owner proposes additional special disinfection process requirements for the integrated equipment to deal with wastewater from epidemic prevention and infection sources.

Sedum Environmental Technology adopts the combined treatment process of AO+MBBR+disinfection in the process selection. All unit cells are covered and sealed to prevent leakage. For the grid adjustment tank and sludge storage tank that may cause bacteria to escape, additional The automatic dispensing point of disinfectant is configured, and the module support of Sedum's remote operation and maintenance platform enables the system to achieve the level of unmanned management.

04 Kitchen Wastewater Treatment

Client Project: 500T/D Catering Wastewater Project in Food Village, Huichang County Rural Revitalization Experimental Zone, Jiangxi Province

This project is an integrated sewage treatment equipment set up to support the Food City project. The project features, the discharge volume is unbalanced, and the peak water volume is 50~60m³/h, which contains a large amount of animal and vegetable oils and food residues. It is a big problem for the stable operation of the sewage system For this reason, Sedum Environmental Technology has designed an integrated equipment of "residue and oil separation + AO-MBR-ultraviolet + sodium hypochlorite double-effect anti-virus process" to deal with it. The residue grease trap has a built-in portable and basket-type residue net to facilitate timely cleaning of food residues. After the treatment of the three-stage grease trap, the oil content of the wastewater can be as low as 2mg/L, which will not affect the subsequent operation of the MBR membrane. + Sodium hypochlorite combined disinfection, to meet the needs of effluent to kill Escherichia coli, supporting the module support of Sedum's remote operation and maintenance platform, so that the system can achieve the level of unmanned management.

Client project: a kitchen waste collection plant in Taiwan

This project is used in the kitchen waste water produced by a kitchen waste treatment plant in a certain place in Taiwan Province. The waste water is characterized by high oil content and high salinity in the water, which is highly corrosive to general materials. The integrated kitchen waste water treatment equipment based on residue oil separation + A2O + MBR", the whole cabinet is made of food-grade SS304 material, with excellent anti-corrosion performance, the whole machine occupies a compact area, and the outer dimension of the equipment is only 4.5m*2.0m *1.8m, which is very convenient for the factory's demand for equipment mobility, and the customer satisfaction is high.

05 Chilled market cleaning wastewater

Guangzhou Fangcun Fish Market and Chilled Fresh Market have integrated treatment equipment for cleaning wastewater, with a processing capacity of 200 tons per day.

The characteristics of wastewater, the wastewater contains a large amount of slag, there are a lot of hair silk threads and aquatic product residues, high animal protein content, and it is easy to spoil. Before the water enters the anoxic area, a hair filter with a filtration accuracy of 2mm is added to effectively intercept the slender hairs and other debris that easily lead to the failure of MBR membrane filament winding. Use, customer satisfaction is high.

06 Scotland tankwash chemical tank cleaning project

The requirements put forward by the customer: the sewage treatment system adopts the physical oil skimming + coagulation air flotation process to ensure that the cleaned sewage reaches the pH value of 6-9, petroleum ≤ 5mg/L, COD ≤ 200mg/L to meet the discharge requirements of the industrial park.
