III Process design

3.1 Sewage treatment technology

After understanding the source and characteristics of the sewage in this project, and referring to the experience of other related sewage treatment projects and industry-leading treatment processes done by our company, the treatment process of "UASB anaerobic process +AOAO" is selected in this scheme based on the principle of stable and reliable operation, saving investment, reducing operating costs, facilitating daily operation and management, and ensuring treatment effect. To ensure that the methane can be produced at the same time the water standard.

3.3 Process flow chart

3.4 Process specification

Preprocessing part

The waste water first passes through the grille channel, and the mechanical grille will separate the large debris in the waste water, including waste paper, cigarette butts, and leftover plastics; The initially separated waste water enters the sump, and is evenly mixed with the pre-treated, oiled and separated food and kitchen waste through the mixer, and then sent to the solid-liquid separation workshop; SS in sewage is removed by solid-liquid separator to reduce the load of subsequent treatment and the risk of fouling in pump. The wastewater filtered by the solid-liquid

separator contains a large number of fine particles that cannot be removed by the solid-liquid separator. After adjusting the stable water volume of the tank, it is stably transported to the primary sedimentation tank through the pump. Coagulant and

flocculant must be added to the wastewater to form large particles of alum into small SS floc, so as to achieve the purpose of gravity precipitation, which not only reduces the negative coagulation load of the subsequent biochemical system, but also the first step of phosphorus removal. The effluent from the primary sedimentation tank is pumped to the UASB tank by lifting pump after mixing in the transfer tank to fully homogenize the water quality and quantity.

Anaerobic portion

Upflow anaerobic sludge bed reactor (UASB) is a kind of reactor with simple structure, which is suitable for low suspended solid organic material. The raw materials enter the digester from the bottom, and contact with the activated sludge in the digester, so that the raw materials can be quickly digested. Undigested organic solid particles and biogas fermentation microorganisms are retained in the digester by natural sedimentation, the supernatant overflows from the upper part of the digester, and the gas is separated by the three-phase separator and enters the gas reservoir through the collecting pipe. This results in a much higher solid retention period (SRT) and microbial retention period (MRT) than the hydraulic retention period, thus improving the decomposition rate of solid organic matter and the efficiency of the digester. Because UASB has simple structure, high volume load rate, short hydraulic residence time of wastewater in the reactor, no stirring is required, and can adapt to relatively large load impact, temperature and pH changes, it is suitable for the treatment of high-concentration organic wastewater, and has a high removal rate of organic pollutants, among which the chemical oxygen consumption (CODCr) removal rate is 80-90%. The removal rate of five-day biochemical oxygen demand (BOD5) is 70-80%, and the removal rate of suspended solids (SS) is 30-50%.

Post-processing section

Due to the high COD and ammonia nitrogen of fecal wastewater, it is difficult to reach the standard after a process of nitrification and denitrification. Moreover, the biodegradable substances in the wastewater after UASB reactor are greatly removed, while most of the remaining substances are difficult to degrade and are difficult to be oxidized by activated sludge. Therefore, this scheme adopts A two-stage A/O process. The wastewater from the UASB reactor enters the two-stage A/O biochemical treatment system, and passes through the first-stage anoxic tank, first-stage aerobic tank, second-stage anoxic tank, second-stage aerobic tank, and sedimentation tank in turn.

The COD and BOD in the wastewater treated by UASB reactor have been removed in a large proportion, and the remaining pollutants belong to the long chain organic matter which is difficult to treat. Therefore, the wastewater is first introduced into the anoxic pool, and the polymer long chain organic matter is broken by facultative bacteria to decompose it into small molecules that are easy to biodegrade. After anoxia, the waste water flows into the aerobic tank, and the metabolism of the acclimated aerobic bacteria decomposes the easily degradable organic matter in the waste water into carbon dioxide and water. Anoxic pond Biological nitrogen removal is mainly carried out in anoxic pond. Biological nitrogen removal includes two processes: nitrification and denitrification. The process of nitrification is the conversion of ammonia nitrogen into nitric nitrogen under the action of nitrifying bacteria. Nitrobacteria are chemoautotrophs, which do not require organic nutrients for their physiological activities. They obtain carbon sources from carbon dioxide and energy from the oxidation of inorganic substances. The denitrification process is to reduce nitric nitrogen and nitrite nitrogen to nitrogen under the action of denitrifying bacteria. Denitrifying bacteria are heterotrophic facultative anaerobic bacteria, it can only use nitric acid and nitrite ion oxygen in the absence of molecular oxygen to breathe, so that nitric acid reduction. The main function of the anoxic pool is to carry out the denitrification process. At the same time, the circulating mixture in the aerobic pool returns to the anoxic pool, and the denitrifying bacteria in the reflux sludge use the organic matter in the sewage as the carbon source to reduce a large amount of nitric nitrogen in the reflux mixture to nitrogen, so as to achieve the purpose of nitrogen removal. The aerobic tank mixture enters the aerobic reaction zone from the anoxic reaction zone. This reaction zone unit is multifunctional. BOD5 removal, nitration and phosphorus absorption reactions are all carried out in this reactor. All three reactions are important, the mixture contains NO3-N, the sludge contains excess phosphorus, and the BOD5 in the sewage is removed. The aerobic tank returns the mixture of 200% of the original sewage to the anoxic reaction tank. Using anoxic + aerobic process, the main function is to remove the residual organic matter in the sewage through the aerobic biochemical process, further degrade COD, and convert ammonia nitrogen into nitrate through the nitrification process. Through the aerobic P absorption and anaerobic P release effect of phosphorus accumulating bacteria (Microgram-negative Brevicella), organic matter in sewage is oxidized and decomposed, and phosphorus in sewage is stored in the bacteria in the form of polyphosphate to form high-phosphorus sludge, which is discharged through the residual sludge and has a good phosphorus removal effect. Before the wastewater from the aerobic tank enters the reaction tank, the sedimentation tank is added to remove the aerobic bacteria formed by aerobic bacteria and the dead and shed SS, which can optimize the treatment environment and treatment effect of the coagulation/flocculation system and reduce the dosage of chemicals. Sludge from sedimentation tank is pumped into anoxic tank through sludge pump to increase sludge reflux of the whole system, and the remaining sludge is discharged into sludge tank for sludge treatment. The effluent water after biochemical treatment contains a large number of dead and shed bacteria, so coagulants and flocculants must be added to the wastewater to form large particles of alum flowers, so as to achieve the purpose of gravity precipitation. After the final sedimentation tank is discharged, the sewage still contains many bacteria, viruses and microorganisms. After the biochemical treatment in the first stage, the microbial indicators may not meet the discharge requirements. Therefore, NaClO must be added to the terminal disinfection tank for disinfection, to remove the bacteria such as coliform in the water, and further oxidize the organic pollutants in the wastewater, so as to better guarantee the discharge of the sewage up to the standard. Finally, the sewage is discharged according to the standard.

Other parts

Biogas is collected through water-sealed tanks, desulfurization tanks and biogas tanks, and then incinerated by boilers. Hot water can be used for heating in the factory area, and excess biogas is burned through the torch.

The residual sludge produced by the sewage station is dehydrated by the screw sludge dewatering machine, and the sludge cake can be transported directly after the moisture content reaches 80%.

3.5 Biogas calculation

Based on the projected water volume, it can be calculated that the daily biogas production is about 540 cubic meters. It is generally believed that a household (3-5 people) uses about 1 cubic meter of biogas per day, and 540 cubic meters of biogas can be used by 540 families for daily cooking.
