The materialized water treatment equipment comprises the following steps during operation:

1. equipment water inlet: carry the waste water in the waste water collecting tank to first PH equalizing basin through stealthily dirty pump, be equipped with in the waste water collecting tank and lack water floater and full water floater, lack the start of water floater control stealthily dirty pump, lack the water floater and have 20 CM's distance from the water tank bottom, can not stand immediately after guaranteeing stealthily dirty pump start because the liquid level has not enough and stop work, will lead to stealthily dirty pump to start too frequently like this, reduce stealthily dirty pump's life. The submersible sewage pump conveys the wastewater to a pipeline of a PH adjusting tank, and a backflow pipeline is arranged on the pipeline and used for controlling the flow and balancing the pressure.

2. Water feeding and dosing in the materialization tank: the sewage submersible pump conveys the wastewater to the PH adjusting tank of the materialization tank, water enters from the top of the PH adjusting tank, meanwhile, the chemicals are added from the position near the water inlet to form upper water inlet, the first water outlet is arranged at the bottom of the tank, so that the process that the water in the first reaction tank enters the second reaction tank forms a diagonal line, and the reaction time of the chemicals is prolonged to the maximum.

The water of reserve reaction tank gets into from the bottom of the pool, adds the position that the medicine pipeline is connected to about 20cm apart from water inlet top, makes the waste water that has just flowed over just begin to react with the medicament, forms into water down, can not cross lowly because of adding medicine pipeline position again, and bottom of the pool impurity forms after equipment shut down and piles up and plug up and add the medicine mouth. The water outlet of the second reaction tank is arranged above the tank, so that the water in the second reaction tank enters the third reaction tank to form a diagonal line, and the reaction time of the medicament is prolonged to the maximum extent.

The water of the PAC reaction tank enters from the top, the dosing pipeline is connected to a position which is about 20cm above the water inlet, so that the water which just flows in starts to react with the medicament to form lower inlet water, and impurities at the bottom of the tank can not be accumulated to block a dosing port after the equipment is shut down because the position of the dosing pipeline is too low; the water outlet of the second reaction tank is arranged above the tank, so that the water in the second reaction tank enters the third reaction tank to form a diagonal line, and the reaction time of the medicament is prolonged to the maximum extent;

the water of PAM reaction tank gets into from the bottom, adds the medicine pipe connection to the water inlet position, makes just flowing waste water that comes begin to react with the medicament, forms into water, is equipped with the agitator pump in the PAM reaction tank. The water outlet of the third reaction tank is arranged at the bottom of the tank, so that a diagonal line is formed in the process that water in the third reaction tank enters the fourth reaction tank, and the reaction time of the medicament is prolonged to the maximum extent.

The water of PAM reaction tank output enters into the swash plate sedimentation tank through pressing from both sides at sedimentation tank awl bottom and swash plate intermediate position, and the delivery port position of here can not be changed to other positions, and the delivery port just overflows the clear water basin with the flocculus above easily, and the delivery port is in the sedimentation tank bottom, and rivers during operation will be washed away the flocculus that descends again and be taken to the clear water basin by rivers in. Under the general condition, the reaction tank is all through the aeration pipe stirring, and behind the PAM reaction tank, because PAM medicament itself gathers the PAM granule that has reacted to form the floccule of large granule, increase weight, be convenient for deposit, if at this time use gaseous stirring, can scatter the large granule floccule that gathers again, will lead to the settling time overlength like this, the mud that deposits out is thinner, can't form the mud piece of blocking when mud is squeezed by the pressure filter, solid stirring pump stirring.

3. Water production and conveying of equipment: clear water overflowing from the sedimentation tank enters a clear water tank, a full water floating ball, a water shortage floating ball and a submersible pump are arranged in the clear water tank, the full water floating ball controls the starting of the materialization equipment main body, the equipment is stopped after the full water floating ball sends a signal, the stirring pump, the filter press and the submersible pump do not influence the use, and the water shortage floating ball controls the operation of the submersible pump.

4. Starting the filter press: the mud delivery pump that equipment mainly used is pneumatic diaphragm pump, and the power supply is gaseous, and the effect that the filter press squeezed is decided to the size of atmospheric pressure, and atmospheric pressure is little, and diaphragm pump operating frequency is low, and the filter press can not filter the moisture in the mud totally, and mud is moist when leading to unloading mud, and the weight is high. Therefore, an air pipe electromagnetic valve is added on the air pipe to control the total air pressure of the pneumatic diaphragm pump, when the filter press is started, the air pipe electromagnetic valve is opened, and the pneumatic diaphragm pump starts to convey sludge into the filter press.

5. And (3) outlet water reflux of the filter press: what the pressure filter pressed under the usual condition is the mud of sedimentation tank bottom, water in the sedimentation tank is through adding the medicine reaction, water all is clear under the general condition, if consider alone that equipment moves under the good condition, the water that the pressure filter came out can directly be discharged, but because the characteristic of equipment, waste water treatment equipment must want people to observe and operate, will appear the maloperation like this at the in-process of operation or the measuring pump can not beat the condition such as medicament, the waste water treatment equipment that leads to produces water muddy, the mud of sedimentation tank all is dirty after the pressure filter squeezes this time, just can not directly discharge. Therefore, the treatment mode of the outlet water of the filter press is changed into the return flow to the waste water collecting pool, and the outlet water can be sent back by using a pipeline direct current or a conveying pump according to the difference that the waste water collecting pool is below or above the ground.

The utility model can balance the water inflow and the water consumption; the operation is stopped immediately when a fault occurs, and the self-protection function is realized; the service life of the motor is prolonged; the equipment after debugging can achieve the purpose of long-term stable water quality of produced water under the condition of normal operation of daily inspection equipment; PH on-line measuring instrument can prevent that too high low medicament that leads to of concentration from can't reacting when PH medicament adds the medicine, goes out the condition that water quality of water is not up to standard.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures made by the contents of the specification and the drawings, or directly or indirectly applied to other related technical fields, are included in the same principle as the protection scope of the present invention.
