Be equipped with by-pass valve control on described abandoned stream pipe and described collecting pipe, be used to regulate the size of flow on abandoned stream pipe and time collecting pipe.
Described upper box body bottom periphery adopts the special construction of back taper domatic, the rainfall initial stage, make things convenient for the concentrated and precipitation of suspension in the rainwater, and enter lower part box via worker's shape opening.The rainfall later stage makes the concentrated and precipitation of small amounts of contamination in the water, and is unlikely with the delivery port discharge of directly flowing through.
The described variable density that goes up class floating ball body, described lower class floating ball body and water is: go up class floating ball body<water<lower class floating ball body.
Described shape of through holes is circular or square.
Described lower part box base plate is pull-out type base plate or rotary plate, is used to carry out deposit clear operations such as bed mud, prevents to stop up.
The invention has the beneficial effects as follows: owing to adopt technique scheme, drainage tank of the present invention have the pre-filtering function, simple in structure, be easy to safeguard, pollutant complexity, early-stage rainwater that degree of contamination is high effectively can be separated with the later stage rainwater, and solved the problem that accurate judgement rainwater is collected dwell time, solve a rainwater resource safety and a difficult problem of rationally utilizing simultaneously.
