Description
Technical Field
The utility model relates to an environmental protection technical field especially relates to a combined type vatch basin.
Background
At present, works in the aspects of water environment treatment such as urban black and odorous water body treatment, sponge city construction, urban sewage collection pipe network construction and the like are vigorously developed in various places of China. Due to historical reasons, most of drainage systems in urban built-up areas in China are rain and sewage converging drainage systems, and if rain and sewage diversion transformation is implemented in the built-up areas, the engineering construction difficulty is high, the construction year limit is long, the engineering investment is huge, and the implementation is difficult in a short period. In order to protect the urban water environment as soon as possible and effectively, the technical strategy of transforming the original direct-discharge type combined flow drainage system into the intercepting type combined flow drainage system is a preferred transformation scheme in the near future.
The intercepting type combined flow drainage is that a sewage intercepting main pipe (the pipe diameter is determined by the intercepting multiple) is built along the bank side of a municipal water system (river and lake) to collect sewage and part of initial precipitation rainwater and send the sewage and part of the initial precipitation rainwater to a sewage treatment plant at the downstream of the municipal water system for treatment. Because the urban confluence pipe is large in quantity and large in pipe diameter, the pipe diameter of the sewage intercepting main pipe is often determined according to the interception multiple of 2-5, and the pipe diameter is small, so that how the confluence pipe is connected with the sewage intercepting main pipe becomes a problem which needs to be carefully considered. In engineering practice, the flood control dike along a river (lake) in a city is already built, in order to save the construction period and reduce the construction cost, a sewage intercepting main pipe is arranged in a river channel outside the flood control dike for building in many places, a converging pipeline passing through the flood control dike is directly connected into an inspection well of the sewage intercepting main pipe, and an overflow port facing a water system is arranged on the wall of the inspection well. This approach presents significant problems:
1. the shut-off times cannot be controlled. The sewage interception main pipe not only needs to receive the rainwater and sewage combined flow in the water collection area, but also needs to transfer the water from the sewage interception main pipe at the upstream of the access point, so that the interception multiple in the running process of the pipeline cannot be controlled, and the impact load (water quality and water quantity) on the treatment structure of the sewage treatment plant is too large, so that the sewage treatment plant is difficult to run; on the other hand, the sewage intercepting main pipe is easily filled with later rainwater, so that a large amount of heavily polluted sewage overflows from the partial intercepting points in the high area.
2. Cause urban drainage subregion confusion, send into high district rain, sewage into the low district, violated high water content high drainage, low water pumping drainage's the principle of discharging nearby, cause the high district to cut the flap valve that sets up on the dirty main pipe and become invalid, the phenomenon that the manhole well lid of low district was jack-up by water to low district rain, sewage are difficult to discharge, easily take place waterlogging phenomenon, and this type of phenomenon has appeared in many places.
3. Excessive rainwater is accumulated in a municipal drainage pipeline system, the number of days for influencing the inflow water quality of a sewage treatment plant by one-time rainfall is increased, and the method is one of important reasons for the condition that the inflow water quality concentration of the sewage treatment plant in southern areas of China is low.
Intercepting wells are arranged on converging pipelines in front of access points in some cities, and sewage and early rainfall water are intercepted to an intercepting main pipe inspection well through a section of intercepting pipe with a small diameter. The problems with this solution are as follows: 1. the intercepting pipe is extremely easy to block due to small pipe diameter, and sewage overflows frequently in dry seasons; 2. if the intercepting well is built on the inner side of a river bank, land needs to be increased, a bank penetrating channel needs to be increased, and engineering implementation is difficult; 3. if the intercepting well is built on the outer side of the river bank, the intercepting main pipe occupies too large the cross section of the river channel, which is not beneficial to flood the river channel, and the engineering implementation difficulty is large and the construction cost is high; 4. the amount of the rainwater and sewage for intercepting is fixed, and the device cannot adapt to the development and change of the sewage collecting pipe network in the region.
Based on the above consideration, the utility model designs a combined type vatch basin.
