What management regulations should be complied with for the cleaning operation in the sewage sedimen

First of all, it is necessary to do a good job in the safety of confined spaces, to ensure smooth air, to strengthen ventilation, to do a good job in fire prevention, as well as the basic labor protection of personnel, equipment electricity, equipment rust and anti-fall prevention. In the process of operation, the methods adopted are different, and the relevant safeguard measures involved are also different. It is best to use a pump to pump all that can be pumped away, and you can also pump while flushing with water to reduce labor intensity.

Bring a hard hat, safety glasses, safety shoes, gloves, rain boots, etc.

Hello, I am happy to answer for you, propose improvement measures for the existing sedimentation tank of the sewage treatment plant, and explain the effectiveness of the measures as follows: Optimization of operating process parameters It is important to track and record the operating parameters of the process, such as effluent characteristics, but it is difficult to select the variables that have the most direct impact on the operation of the process in order to pursue high-quality treatment results. The operator can determine the future process control strategy by looking at the previous data, and if there are many relevant process parameters, then statistical tools can be used to help select the supervised parameters, which are selected based on the regular observation of the effectiveness of specific parameters.

Hello, I am glad to answer for you, put forward improvement measures for the sedimentation tank of the existing sewage treatment plant, and explain the effectiveness of the measures as follows: Jianli County Xingou Town, Shangchewan Town Sewage Treatment Plant, Honghu City Xiaogang Town, Fengkou Town Sewage Treatment Plant and other four township sewage treatment plant supporting pipe network has been basically completed, as soon as possible to improve the operating conditions, to ensure that the end of the year officially put into operation.

(1) According to the form of the primary sedimentation tank and the form of the scraper, determine the mud scraping method and the length of the mud scraping cycle. Avoid sedimenting sludge that is left for too long and causing floating sludge, or scraping sludge too frequently or scraping too quickly to disturb the settled sludge.

2) The primary sedimentation tank generally adopts intermittent sludge discharge, so it is best to achieve automatic control; When self-control cannot be realized, it is necessary to pay attention to summarizing experience and manually grasp the number of sludge discharge and sludge discharge time according to experience. When continuous sludge discharge is used in the sedimentation tank, attention should be paid to the flow rate of sludge discharge and the color of the sludge discharged, so that the sludge discharge concentration meets the process requirements.

3) During the inspection, pay attention to observe whether the water output of each pool is uniform, whether the outlet weir is uniform, whether the weir mouth is blocked by scum, and adjust or repair it in time.

4) During the inspection, pay attention to observe whether the scum in the scum bucket can be successfully discharged, whether the scum scraper and the scum bucket baffle are properly matched, and adjust or repair them in time.

5) Pay attention to whether there is any abnormal sound of mud scraping, slag scraping and sludge discharge equipment during inspection, and check whether there are loose parts, etc., and adjust or repair it in time.

6) The mud discharge pipeline should be flushed at least once a month to prevent sediment, grease and other blockages in the pipeline, especially at the valves, and the number of flushing should be increased in winter. The primary sedimentation tank is emptied regularly (generally once a year) and thoroughly cleaned and inspected.

7) According to the regulations, the routine monitoring items of the primary sedimentation tank should be analyzed and inspected in a timely manner, especially the important items such as SS should be compared in time to determine whether the SS removal rate is normal, and necessary rectification measures should be taken if it declines.

8) Routine monitoring items of the primary sedimentation tank: water temperature, pH value, CODCR, BOD5, TS, SS and solid content and volatile solids content of the discharged water.

What type of primary sedimentation tank is in the plant?

1. Purpose. In order to ensure better sewage treatment and ensure the safety of employees. These precautionary measures are hereby formulated.

2. Scope of application.

This precautionary measure applies to the daily management and operation of employees in the wastewater workshop.

3. Specific provisions.

All employees should have the necessary awareness of safety production, be familiar with the relevant safety production rules and regulations and safety operation procedures, and must understand and master the safety technical characteristics and safety operation skills of their positions.

During working hours, you are not allowed to leave your job without authorization, and you are not allowed to meet customers or sleep.

Work clothes and protective equipment should be worn during working hours, and production personnel are not allowed to wear slippers, high heels, skirts or scarves when they go to work, and they are not allowed to laugh and play in the workplace.

When the machine is turned on, it is necessary to raise its voice, and if it is found that the abnormality is found to be reflected and dealt with in time. Turn off the power when you leave your post.

Frequently check the equipment (such as oil, screw tightness, gate valves, circuit circuits, etc.), and keep the equipment clean, and do not throw foreign objects or hard objects into the equipment to avoid failure.

Do not operate a machine that is not operated by yourself without consent. Pay attention to the machinery in operation, and do not put your hands and feet into it and cause accidents.

In the process of work, if it is found that the jujube digging motor does not rotate, the line is faulty and other electrical problems, you should immediately notify the electrician to check, and you must not repair it yourself. It is forbidden to use the fuse and plug indiscriminately, and to connect and pull the wire without authorization.

The flammable, explosive and toxic supplies required by the laboratory should be placed in a dry and ventilated place and kept by a special person. When using concentrated acids, alkalis and toxic substances, special attention should be paid to safety and protective equipment should be worn.

All kinds of measuring instruments, glassware, and chemical reagents should be kept or used by a special person, and others should not use them casually.

There should be sufficient lighting equipment on structures such as aeration tanks and chemical sedimentation tanks and main passages, and safety should be paid attention to when patrolling or taking water samples to prevent them from falling into the pool.

During the maintenance process, it is necessary to be careful about the slippage and brittleness of the pipes inside and outside the pool to avoid accidents.

Wear a seat belt when working at height to avoid accidents.

The staff on duty must strictly abide by the operating procedures of the processing system, if the sense of responsibility is not strong, or the violation of the safety system causes an error accident, or causes damage to the equipment and facilities, the water quality deteriorates, etc., the funds will be withheld according to the actual situation, and the serious ones will be held accountable and dealt with seriously.

Fourth, safety production and fire prevention system.

Electricians should frequently inspect and maintain electrical appliances, so that each electrical appliance is inspected every day and every week.

Finished products, semi-finished products and other sundries are not allowed to be placed near the switch.

Those who cause disasters due to violations of the fire prevention system and operating procedures must be investigated for economic and criminal responsibility.

Carrying the answer ]: b

According to the different process layout, the sedimentation tank can be divided into the primary sedimentation tank and the secondary sedimentation tank. The primary sedimentation tank is a structure used to remove sinken objects and floating objects in sewage treatment. The secondary sedimentation tank is an important part of the activated sludge system, and its functions are mainly to: separate the sludge; Clarifying, thickening and refluxing of the mixture to the activated sludge.

Its working effect can directly affect the effluent quality and reflux sludge concentration of the activated sludge system. ABC three, the surface load, outlet weir load and sludge static pressure of the primary sedimentation tank are generally larger than those of the secondary sedimentation tank; D, the sludge density of the primary sedimentation tank is higher than that of the secondary sedimentation tank, so the moisture content of the former sludge discharge is generally lower than that of the latter.
