Description

A method for interception and drainage scheduling using water quality and quantity

technical field

The invention relates to the technical field of interception and drainage, in particular to a method for interception and drainage scheduling by utilizing water quality and quantity.

Background technique

At present, environmental problems are becoming more and more prominent. The black and odor of the river system is closely related to the entry of sewage on the bank. The so-called "disease is in the river, and the source is on the bank". The rainwater and the water from the combined pipe network are intercepted into the sewage pipe network and sent to the sewage treatment plant. On sunny days, the total water intake is calculated according to the population of the management area. After the sewage treatment plant is evaluated and transformed, the intercepted sewage can be effectively sent to the sewage treatment plant for processing In rainy days, the amount of water increases greatly, especially in heavy rains and torrential rains. In the interception system, the water level is mainly used to control whether the water in the interception system is discharged into the river or into the sewage pipe network. The surge exceeded its load, resulting in a large number of pipe network overflows and pumping station overflows, especially after rainwater entered, resulting in the original poor water quality of the key parts can not be dispatched, a large number of sewage overflows into the river to cause pollution, at the same time, due to the rainwater on the sewage The serious dilution of sewage in the system leads to the fact that the final water quality of the sewage treatment plant is seriously lower than the water quality requirements for in-plant treatment, the treatment process is affected, and the frequency of process adjustment is high under different rainfall conditions. It also causes river pollution, and the final effect is to do a lot of engineering to intercept pollution along the river, but in the middle of heavy rain, the pollution still enters the river, causing secondary black odor in the river.

In order to solve the problem of black and odor in the river and avoid the secondary black and odor of the river, the conventional method is to intercept the sewage along the river, and use the interception weir or pump station to transport the intercepted water into the sewage pipe network, and pass the water level in the interception system. To control the operation of the weir or pumping station, discharge water to the sewage network or to the river.

Part of the water added after the interception is designed to adjust the storage tank to intercept the increased water volume during the flood season into the adjustment storage tank, and then discharge it into the sewage drainage system and send it to the sewage treatment plant for treatment after the flood season.

At present, the entry of water in the interception system into the sewage drainage system is mainly controlled by the water level. Usually, the interception water is collected into the sewage drainage system in the form of overflow tank and pumping water. The model is used to simulate and calculate the load capacity of the maximum flow into the sewage drainage system. However, due to the lack of basic data, the insufficient accuracy of the urban pipe network data, and the engineering problems left after the new drainage system is rectified, it is impossible to follow the entire system. If the actual state is simulated, the actual dispatching load evaluation data cannot be obtained, resulting in a far difference between the actual operation and the simulation; Rainwater is evaluated to obtain the initial amount of rainwater, and then the discharge time is calculated according to the corresponding amount. This method avoids the drawbacks of the previous method of continuously pumping water into the sewage drainage system to a certain extent, and reduces the amount of rainwater entering the sewage drainage system. However, due to rainfall The type of rain is constantly changing, and the water quality in the closure system is constantly affected by factors such as people's daily life and factory discharge. Effective and accurate discharge of sewage into the sewage drainage system during continuous rainfall will cause a large amount of sewage to overflow into the river and pollute the river.

For a system with a large amount of initial rain and interception water, a regulation and storage tank is often constructed when the interception system is designed. The regulation and storage tank usually controls the water entry of each interception system according to the water level. When the water level reaches the regulation and storage volume, it will not be Then allow the interception water to enter; in this way, after the rain starts, the regulating and storage tank will start to receive the water in the interception system until the regulating and storage tank is full, and the water that cannot be received will enter the river; in this way, when the sewage treatment plant has limited processing capacity, it cannot be treated in time. The water can be received through the adjustment and storage tank. After the rain is over, the adjustment and storage tank can drain water into the sewage system through the pump station within the allowed range of the sewage plant, freeing up the adjustment and storage space to prepare for the next rainfall; this method is Use space to exchange time, but if the water quality and quantity are not controlled, often after a rain, the sewage system will run at full load for a long time, and the regulating tank cannot drain into the sewage system. Almost all the flood seasons in the city are very long. Often, there is no drainage in the storage tank once. The next rainfall will come again. In this way, the storage tank cannot be drained. After the sewage accumulates for a long time, it becomes a "septic tank", which affects the surrounding area. Residents live, and the next rainfall cannot play a role in regulating and storing, and a large amount of intercepted water enters the river and pollutes the river.
