Haidian District sewage extraction service, thorough and attentive details

       The main components of the wastewater treatment pond include sedimentation tanks, oxidation tanks, regulating tanks, and sludge tanks. The sludge mainly consists of hawthorn, settled sludge, and biological sludge. Timely sludge removal is a crucial task in the operation and management of the wastewater treatment pond. The sedimentation tank in the treatment process contains a large amount of sludge, most of which is harmful. If sludge is not removed promptly, anaerobic fermentation can occur, causing the sludge to float to the surface, disrupting the normal operation of the sedimentation tank and deteriorating the quality of the effluent. The primary sedimentation also contains protoplasm and heavy metal compounds. When pumping wastewater incompletely, the tank should be stopped (emptied) and manually flushed to remove sludge. For sedimentation tanks with mechanical sludge removal, it is essential to strengthen the maintenance and management of the sludge removal equipment. In case of a mechanical failure, it should be repaired promptly to avoid excessive sludge accumulation at the bottom of the tank, which can affect the quality of the effluent.
Wastewater Pond Cleaning Construction Plan
1. Close the wastewater sump inlet valve to cut off the water source, address the temporary drainage issue during construction, and affix signage.
2. The sewage pool is an enclosed space. For safety reasons, we have pre-arranged ventilation to ensure safety.
3. Drain the wastewater from the sump pit.
4. Dilute sludge. Use a high-pressure pump to dilute the sludge. Clean the sediment and debris at the bottom of the pool.
5. Fill with clean water for rinsing and promptly remove it until it is clean.
6. Prior to diluting sludge, flush it repeatedly with a vacuum truck. Once the sludge is diluted, activate the pumping equipment, and extract the sludge through pipes into a prepared slurry truck for removal. Prevent secondary pollution to the environment.
7. Resume use of the wastewater pond and inspect related equipment and valves for proper operation.

Wastewater Sump Cleaning Construction Plan
One, Construction Phase Division: Due to the large area of the sewage pool, it is divided into 3 phases for cleaning according to the project requirements for cleaning the sewage pool. The sewage in the pool is suctioned and transported by vacuum trucks to the wastewater treatment plant for regular treatment, and all the sludge at the bottom is transported externally for landfilling.
Two, Clean up the on-site environmental hygiene: In accordance with relevant regulations on dust prevention and control, to ensure that no dust is brought to the factory area during the cleaning of the wastewater pond, a new dirt road has been newly opened on the vacant land of the factory, circumventing the production workshops, and it is managed by a dedicated person.
III. Safety Measures: Establish within the construction area of the sewage pool cleaning, with a dedicated guardian to prevent factory personnel from entering the construction site and causing accidents.

Wastewater pit cleaning can be categorized by function into physical, biological, and chemical methods.
1. Physical Methods: Common methods we use in our daily lives for cleaning septic tanks include gravity separation, centrifugal separation, reverse osmosis, and air flotation. Physical methods are simple and cost-effective for treating structures, suitable for towns with large water capacities, strong self-purification abilities, and low requirements for wastewater treatment. This method primarily utilizes physical actions to separate non-soluble substances from wastewater without altering their chemical properties.
2. Biological Method: This involves a process that utilizes the metabolic functions of microorganisms to decompose and oxidize harmful substances dissolved or colloidal in wastewater into stable inorganic matter, thereby achieving the purpose of wastewater purification. The degree of treatment by the biological method is superior to that of the physical method.
3. Chemical Methods: Common techniques include coagulation, neutralization, oxidation-reduction, and ion exchange. As the names imply, these methods involve using chemical reactions to treat or recover dissolved or colloidal substances in wastewater. Such chemical treatment is often used for industrial wastewater. While chemical treatment offers effective results, it is costly and is typically employed as a follow-up to biological treatment to further enhance the quality of the effluent.

Currently, the resource utilization of wastewater in our country is still in the initial stage, with insufficient and unbalanced development, a low overall utilization level, and a significant gap from the requirements of building a beautiful China. Additionally, there are issues such as incomplete standards, inadequate policies, and the need for further improvement in technological and equipment levels.
Our company adheres to the standards of "green, environmental protection, and energy conservation," and upholds the development philosophy of "promoting technological progress through technological innovation and winning the market and customers with product innovation."
