Summary of Sewage Treatment In the past 20 _ _ years, under the great attention of the district government and the correct leadership of the head office, we have taken sewage treatment as the core, optimized the control process, carefully maintained the equipment, and carefully conducted laboratory analysis to ensure the stable operation of the system. All the work has achieved remarkable results and successfully completed all the work objectives. The work of Shiyang Company for 20 years is summarized as follows:
The first is to overcome difficulties and ensure that the tail water is discharged up to standard.
Whether the sewage treatment system runs stably and whether the tail water reaches the discharge standard is the core and the most important work of our work.
In 20___, the water inflow showed an upward trend, especially in April of 20 _ _, the water inflow increased sharply, reaching the design load of 50,000 tons. Since August, the water volume has increased to 60,000 tons, and the system is overloaded, with the load rate reaching 1.20%. The company overcame the unfavorable factors such as large water inflow and long duration, and adjusted the process plan in real time to ensure the stable operation of the system. In the whole year, * * * treated 206,000 tons of sewage, and the load rate reached 109%, an increase of 1.77 million tons compared with 20 years.
Main effluent indicators: COD: 17. 1mg/L (standard value ≤60mg/l), BOD: 5.3mg/L (standard value ≤20mg/l), SS: 5. 1mg/L (standard value ≤ Ammonia nitrogen: 0.3mg/l (standard value ≤8mg/l), completely reaching the national first-class B standard of Pollutant Discharge Standard for Urban Sewage Treatment Plants. There is no accident exceeding the standard, and most indicators are better than the national first-class A standard.
Second, do your duty and strengthen equipment maintenance and management.
Equipment is the core of sewage treatment system, and good running state of equipment is the key to sewage treatment. This year is the fifth year of uninterrupted operation of the company, and the equipment has entered a period of frequent failures, and the maintenance of the equipment is increasing day by day. In 20 years, * * * has completed more than 60 times of equipment maintenance and troubleshooting. At the same time, the foundation reinforcement of the propeller in the oxidation ditch, the maintenance of the weir gate and the oil change of all propellers and stirrers are completed; Improve the support of inclined conveyor, and add cooling fan to the core equipment surface exposure machine. Cooperate with equipment manufacturers to complete fine grid maintenance and conveyor auger replacement.
This year, in order to strengthen the maintenance of underwater power equipment, learn from the experience of the municipal drainage company and report to the district government for approval, the professional maintenance work of 1 1 set has been completed by outsourcing, so that the propeller, agitator and water pump are in the best working condition all the year round, ensuring the stable operation of the system. According to the post responsibilities, the equipment department adheres to the "three essentials" of equipment management.
That is, first, we should adhere to daily inspections, keep records, and eliminate problems in time when they are found. Second, we must adhere to the regular meeting of equipment management, focus on analyzing the causes of failures, and rectify them in time to prevent the same failures from happening again. Third, we should strictly control the maintenance cost and strive to maintain the parts in the factory. Over the past year, the equipment utilization rate is 85%, and the intact rate is 100%. While ensuring the best operation of the equipment, the Equipment Department strengthens the safety management of power distribution, appoints a special person to be responsible for the power management of the company, regularly tests the power inspection tools and fire-fighting equipment, and promptly reports and handles hidden dangers. For the problem that the high voltage at night affects the safety of equipment operation, it has been reported to the district power supply department for many times, coordinating the substation and adjusting the interval voltage. Through the unremitting efforts of the equipment department, the company's electricity environment has been improved, ensuring the safe and stable operation of the equipment.
Unattended and remote control is a brand-new course, and seven sewage lifting pumping stations have been put into use. Through the research of the production office, we assign a special person to be responsible for the daily operation and management of the pumping stations, patrol and inspect seven pumping stations every week, master the operation status of each pumping station, and rationally allocate the lifting water to ensure the stable and efficient operation of the system.
Three, due diligence, complete the task of water quality analysis.
The analysis of inlet and outlet water quality is an important basis for the adjustment of sewage treatment process parameters, which requires timely, accurate and objective. Laboratory staff overcame the difficulties of heavy workload and many water samples, and analyzed water samples accurately and timely 1 10,000 times throughout the year. At the same time, the water quality of seven sewage pumping stations was analyzed by tracking sampling, which provided detailed and accurate water quality data for the system operation.

More than 10000 test data were also stored, and the original record of 100 Yu Ben was archived. There is no data error and no water sample omission throughout the year. Successfully completed the annual water quality analysis. In the management of dangerous drugs, in strict accordance with the company's management system, arrange special account management. For highly toxic drugs, centralized and fixed-point storage, arrange special personnel to take them, and strictly implement the use declaration process, clearly record the dosage and purpose of drug use, eliminate the harm caused by the loss of toxic and harmful drugs, and ensure the safety of drugs in the laboratory.
Four, serious and responsible, complete the sludge dewatering work.
The concentration, dehydration and discharge of excess sludge is an important part of the whole production. The rapid increase of water inflow not only increases the operating burden of the treatment system, but also increases the working pressure of the sludge dewatering workshop. In order to ensure the normal operation of sewage treatment, the sludge dewatering workshop was separated from the central control room and a workshop leader was appointed by the production office. Since this year 1 month, the shift of sludge desliming workshop has been readjusted from rotation system to special post system. Over the past year, the staff in the sludge dewatering workshop have carefully dispensed medicines, added them accurately and skillfully operated sludge dewatering equipment, successfully completing sludge dewatering. The water content of sludge is controlled within 78.5%, reaching the assessment target of water content less than 80% set at the beginning of the year, and the factory sludge is 6390 tons.
While doing a good job in daily sludge concentration and dehydration, we also strengthen the purchase, consumption, inventory registration and production ledger of dehydrating agent and dephosphorizing agent. Actively cooperate with the central control room to complete the addition of phosphorus removal agents, adding more than 2400 bags of 60 tons of chemicals throughout the year; Cooperate with the equipment department to complete the emergency repair of equipment for more than 20 times.
Five, detail management, ensure the sewage treatment work.
The company has always followed the concept of management performance and management benefit, and put management first.
