Background technology
City direct-discharging combined drainage system is when drought flows, the sewage of Combined sewer system all enters Wastewater Treatment Plant, but while raining, because the disposal ability of Wastewater Treatment Plant is limited, part combined sewage will enter water body, thereby can cause serious water body and natural environment to pollute.For protection of the environment reduces, pollute, conventional counter-measure is transformed into shutoff type combined drainage system, and catchpit is one of them important ancillary structure.Now conventional catchpit has three kinds of forms: great-jump-forward, slot type and weir formula catchpit.The interception ratio n adopting when the size of existing three kinds of its amounts of damming of catchpit and design 0closely bound up.N 0too small effectively to intercept sewage, n 0the excessive rainwater that has dammed a large amount of necessity enters the main that dams, and Sewage Plant is caused to treating capacity pressure, is difficult to determine appropriate n according to actual conditions in design process 0.Therefore, existing catchpit can not be given and in good time control according to amount of rainfall size, in the hope of reaching the best effect of damming.In addition, slot type and great-jump-forward catchpit have a common shortcoming: when instantaneous dirty waste water comes the water yield larger, just may occur overflow, its section of dirty effect is undesirable.Although overflow weir formula catchpit can overcome this shortcoming, but when rainfall is large and the duration is longer, its section of dirty effect is poor, it overflows to water body after the larger rainwater rainwater less with Final pollution thing of pollutant in early stage can being mixed, although played the effect of damming, do not played and cut to greatest extent dirty effect.
Traditional catchpit is gravity current catchpit, and combined sewer buried depth is generally very large, and especially the river water ordinary water level of near cities is higher, so that increase riverbank physical features, causes original catchpit water inlet pipe duct buried depth very large.But in some cases, for reducing difficulty of construction and cost, original direct-discharging combined sewer is dammed and often adopts the main that dams that buried depth is relatively little, and present stage three kinds of traditional gravity current catchpits be difficult to reach requirement.Although occurring that in catchpit transformation process cutting dirty outlet pipe absolute altitude is greater than into the pressure-bearing catchpit of water pipe duct absolute altitude, there is the problems such as alluvial and impeded drainage that very easily produce in this catchpit.

Further, overflow weir is all opened described in dry season, prevents instantaneous large amount of sewage overflow; At the initial stage in rainy season, described height of weir plate remains unchanged, and along with the increase of rainfall, the growth of rainfall duration, opening switch button reduces rapidly described overflow weir the end of to, makes rainwater earial drainages in a large number.
The invention has the beneficial effects as follows:
Can the be automatically controlled automatic adjusting overflow weir height of the present invention, the two-way gauge tap of lifting arranging according to amount of rainfall size operation well head, controls weir gate lifting, rationally regulates water level in catchpit, reaches to greatest extent and cuts a dirty overflow effect.Dry season and initial stage in rainy season overflow weir are opened completely, cut dirt and all enter main, prevent the instantaneous increase generation of water sewage overflow; Instantaneous reduction overflow weir of middle and later periods in rainy season, the end of to, reduces weir gate barrier in sluicing process, and rainwater is completely smooth and easy enters river; When rainwater latter stage or river water level soar, there is pouring in down a chimney phenomenon, immediately overflow weir 4 is risen completely, control river and pour in down a chimney, play flap valve effect.
Because overflow weir is adjustable, the more traditional weir gate of overflow in dry season weir gate is high, instantaneous large amount of sewage overflow can not occur to bleed off pipe phenomenon, and a section dirty main buried depth will be less than conventional dry buried depth, reduce construction cost and difficulty.
The overflow weir of circular arc has increased on the one hand overflow weir and has crossed water length, under the same terms, increased water flow, on the other hand because effluent stream in section dirty main is through catchpit, in cross-section of river short distance, change, water velocity changes immediately, produce disturbance, disturb the sinking of particle in sewage, prevent sludge settling in catchpit.
