[Investment invitation for small new rural domestic sewage treatment equipment] Chemical method is used to treat or dissolve or colloid sewage by chemical reaction, and is mostly used for industrial wastewater. Common methods include coagulation, neutralization, redox and ion exchange. Chemical treatment method has good treatment effect and high cost. It is mostly used for further treatment after biochemical treatment to improve water quality. Classification of sludge: according to the source, sludge can be roughly divided into three categories: water supply sludge (sludge generated from raw water purification, such as water works), domestic sewage sludge and industrial wastewater sludge. According to the composition and nature of sludge, sludge can be divided into organic sludge and inorganic sludge. Organic sludge is hydrophilic sludge with organic matter as the main component, and domestic sewage sludge or mixed sewage sludge belong to this category. Inorganic sludge is mainly composed of inorganic substances, often called sediment, which is generally hydrophobic sludge. This kind of sludge includes sediment in water supply treatment grit chamber and some industrial wastewater physical and chemical treatment processes. According to the classification of sludge treatment process, sludge can be divided into primary sludge, surplus sludge, digested sludge and chemical sludge. Among them, the primary sludge refers to the sediment generated during the primary sewage treatment process; Excess sludge refers to the activated sludge discharged from the secondary sedimentation tank or sedimentation area outside the system; Digested sludge refers to the sludge obtained from aerobic or anaerobic digestion of raw sludge; Chemical sludge refers to the sludge generated after chemically enhanced primary treatment or tertiary treatment. Sludge is a by-product of sewage treatment by physical, chemical, physicochemical and biological methods. It is an extremely complex heterogeneous body composed of organic debris, bacteria, inorganic particles, colloid, etc. The concentration of suspended solids is generally 1-10, and it is in a colloidal state between liquid and solid forms. Problems existing in various types of sludge 1. The moisture content of undrained sludge is higher than 90, the moisture content of initially dewatered sludge is also as high as 80, the transportation cost is high, and the stacking area is large. Direct landfill will squeeze the storage capacity of the landfill, make the landfill scrapped in advance, and cause problems such as blocking the landfill leachate pipe. 2. Sludge contains a variety of minerals, and contains more plant nutrients such as nitrogen and phosphorus, and heavy metal ions such as copper, zinc, chromium, mercury and their salts. When sludge is used for land use, if it is not properly used, it may pollute the land, cause irreversible degradation of cultivated land, and directly threaten the human food chain. Moreover, these substances will enter surface water or groundwater through surface runoff or precipitation and affect their water quality, in which nitrogen and phosphorus even cause eutrophication of water bodies. 3. The content of organic matter is high, so it has a high calorific value. The calorific value after drying is equivalent to the level of lignite, but it is easy to emit odor and affect the quality of atmospheric environment. The following requirements shall be paid attention to during the laying and installation of microporous pipes: 1. First, the laying method of inlet aeration pipes shall be designed according to the water surface area and shape. 2. Prepare various materials according to the design requirements, such as tee, regulating support, glue for bonding, etc. 3. During installation, each pipe joint shall be sealed with glue or pipe hoop to prevent air leakage. 4. It is necessary to ensure that the air output of the aeration pipe is uniform as far as possible, and the length of one aeration pipe is controlled below 10m. When laying, the microporous aeration pipe should be kept level with the ground at the bottom of the tank. The height of the ground of the aeration pipe should be generally high, measured from all parts of the tank, to ensure uniform air output. 5. Aeration pipe shall not contact with sludge to avoid blockage. 6. The main engine shall be installed in the middle of the main pipeline as far as possible to ensure the same air supply of each pipeline. There should be no sundries near the air inlet of the host to avoid blockage. 7. Commissioning shall be carried out after installation. Open the host machine, adjust the aeration pipes one by one, and adjust the height and direction of the aeration pipes until the aeration of the whole microporous pipe is uniform.

Industrial sewage treatment similar to domestic sewage. 6. Sewage treatment in residential quarters and domestic sewage treatment in market towns. [Investment invitation for small new rural domestic sewage treatment equipment] There are many buried sewage treatment processes. On the premise that the effluent reaches the standard, the outstanding advantages are: 1. The equipment is buried under the ground, and it can be greened above. The environment is beautiful. 2. The whole equipment generally does not need to be managed by special personnel. 3. The floor area can be reduced. Parking lots can be built above the equipment, without the need to build plants and other facilities. 4. It has no impact on the surrounding environment, produces less sludge and has less noise than the standard of Class II area. 5. Simple operation, new process, good effect and long service life. 6. The equipment can be arranged according to the standard or special arrangement according to the terrain needs. Buried sewage treatment equipment can treat comprehensive wastewater of domestic system and similar organic sewage. The two-stage biological contact oxidation treatment process adopts the contact oxidation process, and its treatment effect is better than that of the fully mixed or two-stage series complete umbrella mixed biological contact oxidation tank. It is smaller than the activated sludge land, has good adaptability to water quality, good shock load resistance, stable effluent quality, and will not produce sludge bulking. A new type of elastic filler is used in the tank, which has a large specific surface area and is easy for microorganisms to hang and remove the membrane. Under the same organic load conditions, the organic matter removal rate is high, which can improve the solubility of oxygen in the air in water. The maintenance and management of buried sewage treatment equipment is the key to its normal operation. We should protect the equipment from the following aspects. First, be familiar with the underground sewage treatment equipment under management. The operator should carefully read the factory instructions of the product. Generally, the instructions indicate the type, model, specification and working characteristics of the equipment; Key points of operation, precautions, safety regulations, oil filling position, type of grease to be filled, interval of each oil change, etc. The second step is to get familiar with the operating conditions of the equipment, including the startup time, operating conditions, fault phenomena and troubleshooting methods of the equipment. Pay attention to equipment repair and maintenance time during maintenance. During the maintenance and management of the equipment, if the instructions of the equipment indicate the causes of relevant faults, troubleshooting methods, repair time and precautions, the relevant maintenance personnel shall carry out the maintenance of the equipment according to the instructions. Only by doing a good job of maintenance can we work better.
